Description

Dispositivos eléctricos  Electric dispositives

La presente descripción se refiere a dispositivos eléctricos para la autenticación de un objeto físico, tal como por ejemplo, un documento de papel, un embalaje, etc. This description refers to electrical devices for the authentication of a physical object, such as, for example, a paper document, a packaging, etc.

ANTECEDENTES DE LA TÉCNICA BACKGROUND OF THE TECHNIQUE

La autenticación se puede definir como la acción de verificar/confirmar que algo es original (es decir, no es una falsificación) de una manera relativamente fiable. La autenticación de un objeto físico, tal como por ejemplo un documento de papel, un embalaje, etc. puede ser aconsejable en función de su contexto de uso. En un ejemplo, se puede realizar la autenticación de pasaportes en una zona de control de pasaportes para verificar el origen y la identidad de las personas que se desplazan entre diferentes países. En otro ejemplo, se puede llevar a cabo la autenticación de paquetes recibidos en una oficina de correos para identificar paquetes sospechosos.  Authentication can be defined as the act of verifying / confirming that something is original (that is, it is not a fake) in a relatively reliable way. Authentication of a physical object, such as a paper document, packaging, etc. It may be advisable depending on its context of use. In one example, passport authentication can be performed in a passport control zone to verify the origin and identity of people traveling between different countries. In another example, authentication of packages received at a post office can be carried out to identify suspicious packages.

Se sabe que un objeto físico puede ser autenticado mediante el uso de una etiqueta pegada al objeto y que contiene datos de identificación del objeto, y un lector configurado para leer/recibir dichos datos de identificación. La lectura/verificación con éxito de los datos de identificación puede permitir llegar a la conclusión de que el objeto no es una falsificación, de modo que el objeto puede ser admitido como válido por el personal correspondiente. La lectura/verificación sin éxito de los datos de identificación puede dar lugar a dudas sobre su autenticidad, en cuyo caso el objeto puede no ser admitido como válido. En esta situación, el objeto puede ser, por ejemplo, sometido a comprobaciones adicionales en pasos posteriores de comprobación o directamente rechazado. It is known that a physical object can be authenticated by using a tag attached to the object and containing object identification data, and a reader configured to read / receive said identification data. The successful reading / verification of the identification data may allow the conclusion that the object is not a forgery, so that the object can be admitted as valid by the corresponding personnel. The unsuccessful reading / verification of the identification data may give rise to doubts about its authenticity, in which case the object may not be admitted as valid. In this situation, the object can be, for example, subjected to additional checks in subsequent verification steps or directly rejected.

Estas etiquetas acoplables (que se pueden pegar) comprenden típicamente unos medios electrónicos para almacenar y proporcionar de alguna manera al lector unos datos de identificación del objeto. Este almacenamiento y provisión de los datos de identificación pueden requerir que la etiqueta comprenda, por ejemplo, micro-controlador(es), antena(s), etc. configurado(s) para almacenar los datos de identificación e interactuar con el lector de tal manera que se provoca la transmisión de los datos desde la etiqueta hacia el lector. Por lo tanto, tales sistemas de autenticación y, en particular, las etiquetas pueden resultar relativamente complejos en cuanto a su configuración y, por lo tanto, caros. Además, el lector está típicamente orientado y limitado al propósito concreto de leer etiquetas concretas. These attachable labels (which can be attached) typically comprise electronic means for storing and providing in some way to the Reader identification data of the object. This storage and provision of identification data may require the label to comprise, for example, microcontroller (s), antenna (s), etc. configured (s) to store the identification data and interact with the reader in such a way that the transmission of the data from the label to the reader is caused. Therefore, such authentication systems and, in particular, tags can be relatively complex in terms of configuration and, therefore, expensive. In addition, the reader is typically oriented and limited to the specific purpose of reading specific labels.

WO2014165952 A1 describe un ejemplo de dicho tipo de sistemas de autenticación. En particular, se describe una etiqueta RFID/NFC y el correspondiente lector, siendo la etiqueta acoplable (que se puede pegar) a un documento para su consiguiente autenticación. En particular, la etiqueta RFID/NFC se describe comprendiendo un chip micro-controlador y antenas que permiten la comunicación con el lector. Por lo tanto, la autenticación del documento con la etiqueta RFID/NFC pegada al mismo se puede realizar usando el lector para obtener los correspondientes datos de la etiqueta y verificar la validez de los mismos. WO2014165952 A1 describes an example of said type of authentication systems. In particular, an RFID / NFC tag and the corresponding reader are described, the tag being attachable (which can be pasted) to a document for subsequent authentication. In particular, the RFID / NFC tag is described comprising a micro-controller chip and antennas that allow communication with the reader. Therefore, the authentication of the document with the RFID / NFC tag attached to it can be done using the reader to obtain the corresponding data from the tag and verify its validity.

Es un objeto de la presente divulgación proporcionar unos sistemas de autenticación que reduzcan al menos parcialmente al menos algunos de los inconvenientes mencionados anteriormente, dando lugar a mejores modos de autenticar un objeto físico, tal como por ejemplo un documento de papel, un embalaje, etc. It is an object of the present disclosure to provide authentication systems that at least partially reduce at least some of the above-mentioned drawbacks, resulting in better ways of authenticating a physical object, such as for example a paper document, a packaging, etc. .

RESUMEN SUMMARY

En un primer aspecto, se proporciona un dispositivo eléctrico para la autenticación de un objeto físico (por ejemplo, un documento de papel, un embalaje, etc.) en combinación con una primera parte eléctrica y un dispositivo con capacidad de Near Field Communication (NFC). El dispositivo eléctrico comprende una segunda parte eléctrica. La primera parte eléctrica es acoplable (se puede pegar) al objeto físico. La primera parte eléctrica y el dispositivo eléctrico son elementos separados que están configurados para ser dispuestos uno respecto al otro y con respecto al dispositivo NFC de tal manera que, en uso, la primera parte eléctrica y la segunda parte eléctrica se acoplan eléctricamente para formar un circuito resonante (cerrado) que tiene un elemento eléctrico inductivo y un elemento eléctrico capacitivo. Este circuito resonante se forma de tal manera que se produce un acoplamiento inductivo entre el dispositivo NFC y el elemento eléctrico inductivo. Este acoplamiento inductivo se produce de tal manera que se causa una comunicación NFC entre el elemento eléctrico inductivo y el dispositivo NFC. In a first aspect, an electrical device is provided for the authentication of a physical object (for example, a paper document, a packaging, etc.) in combination with a first electrical part and a device with Near Field Communication (NFC capability) ). The electrical device comprises a second electrical part. The first electrical part It is attachable (can be attached) to the physical object. The first electrical part and the electrical device are separate elements that are configured to be arranged with respect to each other and with respect to the NFC device such that, in use, the first electrical part and the second electrical part are electrically coupled to form a resonant (closed) circuit that has an inductive electrical element and a capacitive electrical element. This resonant circuit is formed in such a way that an inductive coupling occurs between the NFC device and the inductive electrical element. This inductive coupling occurs in such a way that an NFC communication is caused between the inductive electrical element and the NFC device.

En algunos ejemplos, se puede proporcionar un sistema de autenticación para la autenticación de un objeto físico (por ejemplo, un documento de papel, un embalaje, etc.). El sistema de autenticación puede comprender un dispositivo eléctrico como el descrito anteriormente y una primera parte eléctrica como la descrita anteriormente. La primera parte eléctrica es acoplable (se puede pegar) al objeto físico, y el dispositivo eléctrico puede tener una segunda parte eléctrica. La primera parte eléctrica y el dispositivo eléctrico pueden ser elementos separados que están configurados para ser dispuestos uno respecto al otro y con respecto a un dispositivo NFC de tal manera que, en uso, la primera parte eléctrica y la segunda parte eléctrica se acoplan eléctricamente para formar un circuito resonante (cerrado) que tiene un elemento eléctrico inductivo y un elemento eléctrico capacitivo. El circuito resonante se puede formar de tal manera que se produce un acoplamiento inductivo entre el dispositivo NFC y el elemento eléctrico inductivo. El acoplamiento inductivo se puede producir de tal manera que se causa una comunicación NFC entre el elemento eléctrico inductivo y el dispositivo NFC. In some examples, an authentication system can be provided for the authentication of a physical object (for example, a paper document, a packaging, etc.). The authentication system may comprise an electrical device such as that described above and a first electrical part such as that described above. The first electrical part is attachable (can be glued) to the physical object, and the electrical device may have a second electrical part. The first electrical part and the electrical device may be separate elements that are configured to be arranged relative to each other and with respect to an NFC device such that, in use, the first electrical part and the second electrical part are electrically coupled to form a resonant (closed) circuit that has an inductive electrical element and a capacitive electrical element. The resonant circuit can be formed in such a way that an inductive coupling between the NFC device and the inductive electrical element occurs. Inductive coupling can occur in such a way that NFC communication is caused between the inductive electrical element and the NFC device.

La primera parte eléctrica y la segunda parte eléctrica se pueden definir como compatibles entre sí en el sentido de que ambas partes están configuradas para crear el circuito resonante a la frecuencia de resonancia de 13,56 MHz, que es la frecuencia a la que se producen las comunicaciones NFC. Por lo tanto, la primera y segunda partes eléctricas pueden tener cualquier combinación de características (por ejemplo, tamaño, disposición, composición, etc.) que permitan la formación del circuito resonante (cerrado) a la frecuencia mencionada. Teniendo en cuenta que la NFC es una tecnología bien conocida, no se proporcionarán más detalles acerca de la NFC en el presente documento. The first electrical part and the second electrical part can be defined as compatible with each other in the sense that both parts are configured to create the resonant circuit at the resonant frequency of 13.56 MHz, which is the frequency at which they occur NFC communications. For the therefore, the first and second electrical parts can have any combination of characteristics (for example, size, arrangement, composition, etc.) that allow the formation of the resonant circuit (closed) at the mentioned frequency. Given that the NFC is a well known technology, no further details about the NFC will be provided in this document.

El dispositivo eléctrico puede ser, por ejemplo, un bolígrafo, un llavero, una tarjeta, etc. , con la segunda parte eléctrica integrada en el mismo. Por lo tanto, se puede usar un dispositivo de múltiples propósitos con el rol anterior atribuido al dispositivo eléctrico. The electrical device can be, for example, a pen, a key ring, a card, etc. , with the second electrical part integrated in it. Therefore, a multi-purpose device can be used with the previous role attributed to the electric device.

Se proporciona en la presente divulgación un sistema de autenticación relativamente simple, barato y flexible, ya que sólo la primera parte eléctrica tiene que estar pegada al objeto físico. Esto es relativamente mucho menos que lo que se necesita en los sistemas de la técnica anterior, en los que se requiere la presencia de configuraciones más sofisticadas en el objeto físico para su autenticación. Dichas configuraciones más sofisticadas pueden comprender, por ejemplo, un circuito completo que tiene un micro-controlador, mientras que el sistema de autenticación propuesto se basa simplemente en la verificación de la existencia de la primera parte eléctrica pegada al objeto físico. Esta verificación se realiza en el dispositivo NFC cuando se produce la comunicación NFC causada por la formación del circuito resonante como resultado del acoplamiento eléctrico entre la primera y segunda partes eléctricas. A relatively simple, cheap and flexible authentication system is provided in the present disclosure, since only the first electrical part has to be attached to the physical object. This is relatively much less than what is needed in prior art systems, in which the presence of more sophisticated configurations in the physical object is required for authentication. Such more sophisticated configurations may comprise, for example, a complete circuit that has a micro-controller, while the proposed authentication system is simply based on the verification of the existence of the first electrical part attached to the physical object. This verification is performed on the NFC device when NFC communication caused by the formation of the resonant circuit occurs as a result of the electrical coupling between the first and second electrical parts.

La primera y segunda partes eléctricas son necesarias para crear el circuito resonante, que es necesario para causar el acoplamiento inductivo y, por lo tanto, la comunicación NFC entre el elemento eléctrico inductivo y el dispositivo NFC. Sin embargo, se puede reutilizar el mismo dispositivo eléctrico (es decir, la segunda parte eléctrica) para la autenticación de diversos objetos físicos, teniendo cada uno de ellos una primera parte eléctrica compatible con la segunda parte eléctrica en los términos descritos anteriormente. Además, se puede reutilizar cualquier dispositivo de propósito general que tenga capacidad de NFC en el contexto del sistema de autenticación propuesto. The first and second electrical parts are necessary to create the resonant circuit, which is necessary to cause inductive coupling and, therefore, NFC communication between the inductive electrical element and the NFC device. However, the same electrical device (i.e. the second electrical part) can be reused for the authentication of various physical objects, each having a first part electrical compatible with the second electrical part in the terms described above. In addition, any general purpose device that has NFC capability in the context of the proposed authentication system can be reused.

Por lo tanto, un aspecto relevante del sistema de autenticación propuesto puede ser que se proporciona un alto nivel de reutilización (del dispositivo eléctrico y dispositivo NFC) para la autenticación de una pluralidad de objetos físicos. Sólo se necesita que la primera parte eléctrica (compatible con la segunda parte eléctrica) esté pegada a cada uno de los objetos físicos a autenticar. Por consiguiente, la primera parte eléctrica puede ser el único componente no reutilizable en el sistema de autenticación. Therefore, a relevant aspect of the proposed authentication system may be that a high level of reuse (of the electrical device and NFC device) is provided for the authentication of a plurality of physical objects. It is only necessary that the first electrical part (compatible with the second electrical part) be attached to each of the physical objects to be authenticated. Therefore, the first electrical part may be the only non-reusable component in the authentication system.

En algunas implementaciones, la primera parte eléctrica puede ser acoplable (se puede pegar) al objeto físico mediante impresión con una tinta conductora o, alternativamente, mediante Tecnología de Montaje Superficial (SMT - Surface Mount Technology) o, alternativamente, mediante una combinación de ambas técnicas. Un aspecto de usar la impresión con tinta conductora puede ser que se puede proveer el objeto físico (a autenticar) con la primera parte eléctrica de una manera relativamente fácil y barata. Cuando se utiliza la tecnología de montaje superficial (SMT), el dispositivo resultante puede ser denominado como un dispositivo de montaje superficial (SMD - suríace- mount device). En algunos ejemplos, la segunda parte eléctrica se puede pegar al dispositivo eléctrico mediante impresión con una tinta conductora o, alternativamente, mediante Tecnología de montaje superficial (SMT) o, alternativamente, mediante una combinación de ambas técnicas. Un aspecto de usar la impresión con tinta conductora puede ser que se puede proveer el dispositivo eléctrico con la segunda parte eléctrica de una manera relativamente fácil y barata. Cuando se utiliza la tecnología de montaje superficial (SMT), el dispositivo resultante puede ser denominado como un dispositivo de montaje superficial (SMD). In some implementations, the first electrical part can be attachable (can be glued) to the physical object by printing with a conductive ink or, alternatively, by Surface Mount Technology (SMT - Surface Mount Technology) or, alternatively, by a combination of both techniques One aspect of using conductive ink printing may be that the physical object (to be authenticated) can be provided with the first electrical part in a relatively easy and cheap manner. When surface mount technology (SMT) is used, the resulting device can be referred to as a surface mount device (SMD - suríace - mount device). In some examples, the second electrical part can be glued to the electrical device by printing with a conductive ink or, alternatively, by Surface Mount Technology (SMT) or, alternatively, by a combination of both techniques. One aspect of using conductive ink printing may be that the electrical device can be provided with the second electrical part in a relatively easy and cheap manner. When surface mount technology (SMT) is used, the The resulting device can be referred to as a surface mount device (SMD).

La impresión con tinta conductora (que comprende, por ejemplo, partículas de plata) se puede realizar sobre cualquier sustrato con una porosidad que permita el pegado relativamente fiable de la tinta al mismo, tal como por ejemplo, papel, plástico, etc. Se pueden usar diferentes tecnologías/dispositivos para la impresión con tinta conductora, tal como por ejemplo la impresión por serigrafía, la impresión de inyección de tinta, etc. La tinta conductiva puede ser una tinta offset conductiva, por ejemplo. La serigrafía puede permitir la obtención de una capa de tinta (pegada al sustrato) más gruesa y, por lo tanto, con una menor resistencia eléctrica en comparación con la obtenida usando la impresión de inyección de tinta. La impresión de inyección de tinta con tinta conductora puede requerir un cabezal de impresión adaptado especialmente para evitar su obstrucción con las partículas conductoras. En general, la impresión con tinta conductora se puede realizar de forma relativamente fiable en función del sustrato, la tinta y la tecnología/dispositivo de impresión elegidos. En algunas configuraciones, la primera parte eléctrica puede comprender una primera placa de contacto eléctrico (first electrical pad) y una segunda placa de contacto eléctrico (second electrical pad), y la segunda parte eléctrica (del dispositivo eléctrico) puede comprender una tercera placa de contacto eléctrico y una cuarta placa de contacto eléctrico. Además, el dispositivo eléctrico puede estar configurado para ser dispuesto con respecto a la primera parte eléctrica de tal manera que, en uso, la primera placa de contacto eléctrico está en contacto con una de las placas de contacto eléctrico tercera y cuarta, y la segunda placa de contacto eléctrico está en contacto con la otra de las placas de contacto eléctrico tercera y cuarta. Por lo tanto, con dichas primera, segunda, tercera y cuarta placas de contacto eléctrico, el circuito resonante se puede formar por medio de contacto (contact-based manner). Las placas de contacto eléctricas (electrical pads) anteriores se pueden dimensionar y disponer de cualquier manera que permita que la primera y segunda partes eléctricas entren en contacto de manera efectiva para formar el circuito resonante cuando el dispositivo eléctrico y la primera parte eléctrica se disponen relativamente entre sí de forma adecuada. Printing with conductive ink (comprising, for example, silver particles) can be performed on any substrate with a porosity that allows relatively reliable bonding of the ink thereto, such as, for example, paper, plastic, etc. Different technologies / devices can be used for conductive ink printing, such as screen printing, inkjet printing, etc. The conductive ink may be a conductive offset ink, for example. Screen printing can allow obtaining a thicker ink layer (glued to the substrate) and, therefore, with a lower electrical resistance compared to that obtained using inkjet printing. Inkjet printing with conductive ink may require a printhead specially adapted to prevent clogging with the conductive particles. In general, printing with conductive ink can be performed relatively reliably depending on the substrate, the ink and the printing technology / device chosen. In some configurations, the first electrical part may comprise a first electrical contact plate (first electrical pad) and a second electrical contact plate (second electrical pad), and the second electrical part (of the electrical device) may comprise a third electrical plate electrical contact and a fourth electrical contact plate. In addition, the electrical device may be configured to be disposed with respect to the first electrical part such that, in use, the first electrical contact plate is in contact with one of the third and fourth electrical contact plates, and the second Electrical contact plate is in contact with the other of the third and fourth electrical contact plates. Therefore, with said first, second, third and fourth electrical contact plates, the resonant circuit can be formed by means of contact (contact-based manner). The electrical contact plates above can be sized and arranged in any way that allows the first and second electrical parts to come into contact effectively to form the resonant circuit when the electrical device and the first electrical part are arranged relatively each other properly.

En implementaciones alternativas, la primera parte eléctrica puede comprender un primer devanado eléctrico y un segundo devanado eléctrico, y la segunda parte eléctrica (del dispositivo eléctrico) puede comprender un tercer devanado eléctrico y un cuarto devanado eléctrico. Además, el dispositivo eléctrico puede estar configurado para ser dispuesto con respecto a la primera parte eléctrica de tal manera que, en uso, el primer devanado eléctrico se acopla inductivamente con uno de los devanados eléctricos tercero y cuarto, y el segundo devanado eléctrico se acopla inductivamente con el otro de los devanados eléctricos tercero y cuarto. Por lo tanto, el circuito resonante (cerrado) se puede formar sin contacto con dichos primer, segundo, tercer y cuarto devanados. Este enfoque sin contacto puede permitir una operación más cómoda y más rápida del sistema de autenticación. In alternative implementations, the first electrical part may comprise a first electrical winding and a second electrical winding, and the second electrical part (of the electrical device) may comprise a third electrical winding and a fourth electrical winding. In addition, the electrical device may be configured to be disposed with respect to the first electrical part such that, in use, the first electrical winding is inductively coupled with one of the third and fourth electrical windings, and the second electrical winding is coupled inductively with the other of the third and fourth electric windings. Therefore, the resonant (closed) circuit can be formed without contact with said first, second, third and fourth windings. This contactless approach can allow for more convenient and faster operation of the authentication system.

En algunos ejemplos, el elemento eléctrico inductivo puede estar comprendido en la primera parte eléctrica y el elemento eléctrico capacitivo puede estar comprendido en la segunda parte eléctrica (del dispositivo eléctrico). Alternativamente, el elemento eléctrico capacitivo puede estar comprendido en la primera parte eléctrica y el elemento eléctrico inductivo puede estar comprendido en la segunda parte eléctrica (del dispositivo eléctrico). In some examples, the inductive electrical element may be comprised in the first electrical part and the capacitive electrical element may be comprised in the second electrical part (of the electrical device). Alternatively, the capacitive electrical element may be comprised in the first electrical part and the inductive electrical element may be comprised in the second electrical part (of the electrical device).

En otra alternativa, el elemento eléctrico inductivo y el elemento eléctrico capacitivo pueden estar comprendidos en la segunda parte eléctrica (del dispositivo eléctrico). En esta configuración, la primera parte eléctrica puede comprender simplemente una pista conductora y las correspondientes placas de contacto (para la conexión con contacto) o devanados (para el acoplamiento sin contacto) destinados a cerrar el circuito resonante. Este enfoque puede hacer que el sistema sea significativamente barato, ya que se minimiza la complejidad de la primera parte eléctrica, que puede ser el único componente no reutilizable del sistema. In another alternative, the inductive electrical element and the capacitive electrical element may be comprised in the second electrical part (of the electrical device). In this configuration, the first electrical part can simply comprise a conductive track and the corresponding plates of contact (for connection with contact) or windings (for coupling without contact) intended to close the resonant circuit. This approach can make the system significantly cheap, since the complexity of the first electrical part is minimized, which may be the only non-reusable component of the system.

En aún otras implementaciones alternativas, tanto el elemento eléctrico inductivo como el elemento eléctrico capacitivo pueden estar comprendidos en la primera parte eléctrica (que es acoplable o se puede pegar al objeto a autenticar). En este caso, la segunda parte eléctrica (del dispositivo eléctrico) puede comprender simplemente una pista conductora y las correspondientes placas de contacto (para la conexión con contacto) o devanados (para el acoplamiento sin contacto) destinados a cerrar el circuito resonante. El elemento inductivo puede comprender cualquier tipo de elemento configurado para generar una inductancia, y el elemento capacitivo puede comprender cualquier tipo de elemento configurado para generar una capacitancia, siendo dichas inductancia y capacitancia compatibles en el sentido descrito anteriormente. El elemento inductivo puede comprender, por ejemplo, un devanado (con, por ejemplo, forma de espiral), una inductancia SMD, etc. El elemento capacitivo puede comprender, por ejemplo, un condensador, dos capas conductoras impresas en caras opuestas de un sustrato dieléctrico (por ejemplo, papel), etc. El elemento inductivo y el elemento capacitivo pueden tener cualquier combinación de características (por ejemplo, tamaño, disposición, composición, etc.) que permitan la formación del circuito resonante a la frecuencia NFC de 13,56 MHz cuando el dispositivo eléctrico y la primera parte eléctrica se disponen de forma adecuada relativamente entre sí. In still other alternative implementations, both the inductive electrical element and the capacitive electrical element may be comprised in the first electrical part (which is attachable or can be attached to the object to be authenticated). In this case, the second electrical part (of the electrical device) may simply comprise a conductive track and the corresponding contact plates (for contact connection) or windings (for contactless coupling) intended to close the resonant circuit. The inductive element may comprise any type of element configured to generate an inductance, and the capacitive element may comprise any type of element configured to generate a capacitance, said inductance and capacitance being compatible in the sense described above. The inductive element may comprise, for example, a winding (with, for example, spiral form), an SMD inductance, etc. The capacitive element may comprise, for example, a capacitor, two conductive layers printed on opposite faces of a dielectric substrate (eg, paper), etc. The inductive element and the capacitive element can have any combination of characteristics (for example, size, arrangement, composition, etc.) that allow the formation of the resonant circuit at the NFC frequency of 13.56 MHz when the electrical device and the first part electrical are adequately arranged relatively with each other.

En algunos ejemplos, el dispositivo NFC, que puede ser un teléfono inteligente con capacidad de NFC, puede estar comprendido en el sistema de autenticación. En este caso, se proporciona un sistema de autenticación completo con un dispositivo de propósito general como el dispositivo NFC. Esto puede hacer que el sistema sea más barato en comparación con sistemas de la técnica anterior basados en un dispositivo de propósito particular que actúa como lector de los datos de identificación del objeto a autenticar. In some examples, the NFC device, which may be an NFC-capable smartphone, may be comprised in the system of authentication. In this case, a complete authentication system is provided with a general purpose device such as the NFC device. This can make the system cheaper compared to prior art systems based on a particular purpose device that acts as a reader of the identification data of the object to be authenticated.

De acuerdo con algunos ejemplos, el dispositivo eléctrico puede comprender además un circuito integrado que almacena unos datos que son legibles según la norma NFC y, por lo tanto, transmisibles a través de la comunicación NFC causada. En implementaciones particulares, el dispositivo NFC puede estar configurado para leer los datos almacenados en el circuito integrado del dispositivo eléctrico, de manera que dichos datos pueden ser obtenidos y procesados por el dispositivo NFC. According to some examples, the electrical device may further comprise an integrated circuit that stores data that is readable according to the NFC standard and, therefore, transmissible through the NFC communication caused. In particular implementations, the NFC device may be configured to read the data stored in the integrated circuit of the electrical device, so that such data can be obtained and processed by the NFC device.

Los datos leídos/obtenidos por el dispositivo NFC pueden ser comparados con los datos conocidos como existentes en el circuito integrado del dispositivo eléctrico con el fin de validar la operación del sistema de autenticación. Si los datos obtenidos por el dispositivo NFC corresponden a los datos conocidos como almacenados en el circuito integrado, se puede concluir que se ha producido la comunicación NFC entre el dispositivo NFC y los elementos eléctricos inductivo y capacitivo del sistema de autenticación. De lo contrario, algún componente externo al sistema de autenticación puede haber participado de forma maliciosa o accidental en la comunicación NFC. Por lo tanto, se puede proporcionar un sistema de autenticación más fiable con dichos medios de verificación. The data read / obtained by the NFC device can be compared with the data known as existing in the integrated circuit of the electrical device in order to validate the operation of the authentication system. If the data obtained by the NFC device corresponds to the data known as stored in the integrated circuit, it can be concluded that NFC communication has occurred between the NFC device and the inductive and capacitive electrical elements of the authentication system. Otherwise, some component outside the authentication system may have participated maliciously or accidentally in NFC communication. Therefore, a more reliable authentication system can be provided with said verification means.

En ejemplos de la presente divulgación, el sistema de autenticación puede comprender además un código bidimensional configurado para ser pegado a una superficie del objeto físico. En ejemplos particulares, el código bidimensional puede comprender un código de barras y/o un código de respuesta rápida (QR - Quick Response). El dispositivo NFC puede estar configurado además para leer y decodificar el código tridimensional. El código tridimensional puede codificar datos adicionales que pueden estar relacionados de alguna manera con los datos almacenados en el circuito integrado del dispositivo eléctrico. Estos datos adicionales, una vez decodificados por el dispositivo NFC, se pueden usar para enriquecer la operación de autenticación, para añadir más información para el seguimiento de la operación de autenticación, etc. In examples of the present disclosure, the authentication system may further comprise a two-dimensional code configured to be attached to a surface of the physical object. In particular examples, the two-dimensional code may comprise a barcode and / or a quick response code (QR - Quick Response). The NFC device may be also configured to read and decode the three-dimensional code. The three-dimensional code may encode additional data that may be related in some way to the data stored in the integrated circuit of the electrical device. This additional data, once decoded by the NFC device, can be used to enrich the authentication operation, to add more information for tracking the authentication operation, etc.

La Figura 1 es un diagrama de bloques que ¡lustra esquemáticamente un sistema de autenticación de acuerdo con un ejemplo. Este sistema de autenticación puede comprender una primera parte eléctrica 1 10, un dispositivo eléctrico 105 que tiene una segunda parte eléctrica 1 1 1 , y un dispositivo con capacidad de NFC 102. La primera parte eléctrica 1 10 puede comprender un elemento eléctrico inductivo 101 y puede estar pegada a un objeto físico 100 a autenticar. El objeto físico 100 puede ser un documento de papel, por ejemplo.  Figure 1 is a block diagram that schematically illustrates an authentication system according to an example. This authentication system may comprise a first electrical part 1 10, an electrical device 105 having a second electrical part 1 1 1, and a device with NFC capacity 102. The first electrical part 1 10 may comprise an inductive electrical element 101 and It can be attached to a physical object 100 to authenticate. The physical object 100 may be a paper document, for example.

El elemento eléctrico inductivo puede ser, por ejemplo, un devanado eléctrico 101 con forma de espiral impreso en una superficie del documento de papel 100 con una tinta conductora. La segunda parte eléctrica 1 1 1 puede comprender un elemento eléctrico capacitivo 106 que puede comprender, por ejemplo, un condensador eléctrico. The inductive electrical element may be, for example, a spiral-shaped electric winding 101 printed on a surface of the paper document 100 with a conductive ink. The second electrical part 1 1 1 may comprise a capacitive electrical element 106 which may comprise, for example, an electrical capacitor.

La primera parte eléctrica 101 y el dispositivo eléctrico 105 se muestran como elementos separados. El elemento eléctrico inductivo 101 y el elemento eléctrico capacitivo 106 pueden estar configurados para crear un circuito resonante 109 a una frecuencia de resonancia de sustancialmente 13,56 MHz cuando se disponen relativamente entre sí de forma conveniente. La frecuencia de resonancia de 13,56 MHz es la frecuencia a la que se producen las comunicaciones NFC. The first electrical part 101 and the electrical device 105 are shown as separate elements. The inductive electrical element 101 and the capacitive electrical element 106 may be configured to create a resonant circuit 109 at a resonance frequency of substantially 13.56 MHz when conveniently arranged relative to each other. The 13.56 MHz resonance frequency is the frequency at which NFC communications occur.

El dispositivo NFC 102 (por ejemplo, un teléfono inteligente con capacidad de NFC) puede comprender un módulo NFC estándar 103 configurado para establecer comunicaciones NFC. En el caso de la presente divulgación, el módulo NFC 103 puede comunicarse de acuerdo con los principios NFC con el elemento eléctrico inductivo 101 cuando se forma el circuito resonante 109. Este módulo NFC 103 puede pre-existir en un dispositivo de uso general pre- existente, como por ejemplo, un teléfono inteligente. El uso de un dispositivo de propósito general (en lugar de un dispositivo de propósito particular) puede hacer que el sistema de autenticación sea más barato y más versátil. La comunicación NFC se puede producir a causa de un acoplamiento inductivo 108 entre el módulo NFC 103 y el elemento eléctrico inductivo 101 una vez que el elemento eléctrico inductivo 101 , el elemento eléctrico capacitivo 106 y los correspondientes medios de conexión/acoplamiento han formado el circuito resonante 109. The NFC 102 (for example, an NFC-capable smartphone) may comprise a standard NFC module 103 configured to establish NFC communications. In the case of the present disclosure, the NFC module 103 may communicate in accordance with the NFC principles with the inductive electrical element 101 when the resonant circuit 109 is formed. This NFC module 103 may pre-exist in a pre-general purpose device existing, such as a smartphone. The use of a general purpose device (instead of a particular purpose device) can make the authentication system cheaper and more versatile. NFC communication can occur because of an inductive coupling 108 between the NFC module 103 and the inductive electrical element 101 once the inductive electrical element 101, the capacitive electrical element 106 and the corresponding connection / coupling means have formed the circuit resonant 109.

El elemento eléctrico capacitivo 106 puede estar pegado a una superficie del dispositivo eléctrico 105 mediante, por ejemplo, Tecnología de Montaje Superficial (SMT) o, alternativamente, mediante impresión con una tinta conductora. En el primer caso, el dispositivo resultante sería un dispositivo de montaje superficial (SMD). The capacitive electrical element 106 may be glued to a surface of the electrical device 105 by, for example, Surface Mount Technology (SMT) or, alternatively, by printing with a conductive ink. In the first case, the resulting device would be a surface mount device (SMD).

El dispositivo eléctrico 105 puede comprender además un circuito integrado 107 que puede estar configurado para almacenar unos datos legibles según la norma NFC. Dichos datos pueden ser transmitidos desde el dispositivo eléctrico 105 al dispositivo NFC 102 a través de la comunicación NFC inducida. Entonces, el dispositivo NFC 102 puede verificar si los datos obtenidos corresponden a los datos conocidos como existentes en el circuito integrado 107, en cuyo caso el documento 100 puede considerarse autenticado. El dispositivo NFC 102 puede comprender además una aplicación (o software o programa informático) 104 configurado para realizar dicha lectura y verificación de los datos proporcionados por el módulo NFC y que tienen su origen en el circuito integrado 107 del dispositivo eléctrico 105. The electrical device 105 may further comprise an integrated circuit 107 that can be configured to store readable data according to the NFC standard. Said data can be transmitted from the electrical device 105 to the NFC device 102 through the induced NFC communication. Then, the NFC device 102 can verify whether the data obtained corresponds to the data known as existing in the integrated circuit 107, in which case the document 100 can be considered authenticated. The NFC device 102 may further comprise an application (or software or computer program) 104 configured to perform said reading and verification of the data provided by the NFC module and which originate from the integrated circuit 107 of the electrical device 105.

La verificación de que los datos obtenidos corresponden a los datos almacenados en el circuito integrado 107 puede permitir asegurar que se ha producido la comunicación NFC entre el dispositivo NFC 102 y los elementos inductivo y capacitivo 101 , 106 del sistema de autenticación. Si los datos obtenidos no corresponden a los datos conocidos como almacenados en el circuito integrado 107, esto puede implicar que la comunicación NFC se ha producido a causa de la participación de otros elementos que no pertenecen al sistema de autenticación. Estos elementos "externos" pueden estar presentes en las proximidades del sistema de forma maliciosa o accidental. Verification that the data obtained corresponds to the data stored in the integrated circuit 107 can ensure that NFC communication has occurred between the NFC device 102 and the inductive and capacitive elements 101, 106 of the authentication system. If the data obtained do not correspond to the data known as stored in the integrated circuit 107, this may imply that the NFC communication has occurred due to the participation of other elements that do not belong to the authentication system. These "external" elements may be present in the vicinity of the system maliciously or accidentally.

El sistema de autenticación puede comprender además un código bidimensional (no mostrado), tal como por ejemplo, un código de barras y/o un código QR, y el dispositivo NFC 102 puede estar configurado además para leer y decodificar dicho código bidimensional. Los datos almacenados en el circuito integrado 107 y los datos codificados en el código bidimensional pueden estar relacionados entre sí de alguna manera. De este modo, el dispositivo NFC 102 puede combinar los datos procedentes del circuito integrado 107 y los datos procedentes del código bidimensional con el fin de enriquecer la operación de autenticación, añadir más información para el seguimiento de la operación, etc. The authentication system may further comprise a two-dimensional code (not shown), such as, for example, a barcode and / or a QR code, and the NFC 102 device may also be configured to read and decode said two-dimensional code. The data stored in the integrated circuit 107 and the data encoded in the two-dimensional code may be related to each other in some way. In this way, the NFC 102 device can combine the data from the integrated circuit 107 and the data from the two-dimensional code in order to enrich the authentication operation, add more information for the operation tracking, etc.

De este modo, la autenticación del documento de papel 100 se puede realizar utilizando el sistema de la Figura 1 simplemente para verificar (en el dispositivo NFC) que el devanado especialmente configurado 101 está pegado al documento de papel 100. La presencia del devanado especialmente configurado 101 puede permitir concluir que el documento 100 no es una falsificación. La ausencia del devanado especialmente configurado 101 puede permitir concluir que el documento 100 puede ser una falsificación. Thus, the authentication of the paper document 100 can be performed using the system of Figure 1 simply to verify (in the NFC device) that the specially configured winding 101 is attached to the paper document 100. The presence of the specially configured winding 101 may allow to conclude that document 100 is not a forgery. The absence of the specially configured winding 101 may allow to conclude that the document 100 may be a forgery.

En otras partes de la descripción se proporcionarán, con referencia a otras figuras, detalles sobre cómo se pueden conectar o acoplar entre sí el elemento eléctrico inductivo 101 y el elemento eléctrico capacitivo 106 con el fin de formar el circuito resonante (cerrado) 109. In other parts of the description, details on how the inductive electrical element 101 and the capacitive electrical element 106 can be connected or connected to each other will be provided in order to form the resonant (closed) circuit 109.

La Figura 2a es una representación esquemática de un sistema de autenticación de acuerdo con un ejemplo adicional. Este sistema de autenticación es similar al ¡lustrado en la Figura 1 . En particular, el sistema de autenticación de la figura 2a se muestra comprendiendo una primera parte eléctrica 213 y un dispositivo eléctrico 206 que tiene una segunda parte eléctrica 212. La primera parte eléctrica 213 puede comprender una elemento eléctrico inductivo (por ejemplo un devanado con forma de espiral) 201 y una primera y segunda placas de contacto 202, 203 conectadas eléctricamente a respectivos extremos del devanado 201 . El devanado 201 , la primera y segunda placas de contacto 202, 203 y las conexiones eléctricas pueden estar pegadas a un objeto físico (por ejemplo, un documento de papel) 200 a autenticar. La segunda parte eléctrica 212 puede comprender un elemento eléctrico capacitivo 207 (por ejemplo, un condensador) y una tercera y cuarta placas de contacto 208, 209 conectadas eléctricamente a respectivos extremos del condensador 207. La primera parte eléctrica 213 y el dispositivo eléctrico 206 se muestran como elementos separados que están configurados para ser dispuestos uno respecto al otro y con respecto a un dispositivo NFC 205 de tal manera que, en uso, la primera parte eléctrica 213 y la segunda parte eléctrica 212 forman un circuito resonante (cerrado) 21 1 . Este circuito resonante 21 1 se puede formar de tal manera que se produce un acoplamiento inductivo entre el dispositivo NFC 205 y el elemento eléctrico inductivo 201 , causando dicho acoplamiento inductivo una comunicación NFC 204 entre el elemento eléctrico inductivo 201 y el dispositivo NFC 205. El dispositivo eléctrico 206 puede comprender además un circuito integrado 210 conectado a la segunda parte eléctrica 212 y configurado para almacenar unos datos para su transmisión al dispositivo NFC 205 a través de la comunicación NFC 204 causada. Estos datos pueden ser utilizados como un mecanismo de segundad para asegurar que la comunicación NFC ha sido causada únicamente por los componentes del sistema de autenticación sin la intervención de componentes externos dispuestos en las proximidades del sistema de forma maliciosa o accidental. El dispositivo eléctrico 206 puede estar configurado para ser dispuesto con respecto a la primera parte eléctrica 213 de tal manera que, en uso, la primera y segunda placas de contacto 202, 203 están en contacto con la tercera y cuarta placas de contacto 208, 209 para formar el circuito resonante (cerrado) 21 1 . En particular, la primera placa de contacto eléctrico 202 puede estar en contacto con una de las placas de contacto eléctrico tercera y cuarta 208, 209, y la segunda placa de contacto eléctrico 203 puede estar en contacto con la otra de las placas de contacto eléctrico tercera y cuarta 208, 209. De este modo, con dicho enfoque basado en placas de contacto, se puede formar el circuito resonante 21 1 entre la primera y segunda partes eléctricas 213, 212 por medio de contacto (contact-based manner). Figure 2a is a schematic representation of an authentication system according to an additional example. This system of Authentication is similar to the one illustrated in Figure 1. In particular, the authentication system of Fig. 2a is shown comprising a first electrical part 213 and an electrical device 206 having a second electrical part 212. The first electrical part 213 may comprise an inductive electrical element (for example, a winding with a shape spiral) 201 and a first and second contact plates 202, 203 electrically connected to respective ends of the winding 201. The winding 201, the first and second contact plates 202, 203 and the electrical connections may be attached to a physical object (for example, a paper document) 200 to be authenticated. The second electrical part 212 may comprise a capacitive electrical element 207 (for example, a capacitor) and a third and fourth contact plates 208, 209 electrically connected to respective ends of the capacitor 207. The first electrical part 213 and the electrical device 206 are they show as separate elements that are configured to be arranged with respect to each other and with respect to an NFC 205 device such that, in use, the first electrical part 213 and the second electrical part 212 form a resonant (closed) circuit 21 1 . This resonant circuit 21 1 can be formed in such a way that an inductive coupling occurs between the NFC 205 device and the inductive electrical element 201, said inductive coupling causing an NFC 204 communication between the inductive electrical element 201 and the NFC 205 device. Electrical device 206 may further comprise an integrated circuit 210 connected to the second electrical part 212 and configured to store data for transmission to the NFC 205 through the NFC 204 communication caused. This data can be used as a security mechanism to ensure that NFC communication has been caused solely by the components of the authentication system without the intervention of external components arranged in the vicinity of the system maliciously or accidentally. The electrical device 206 may be configured to be disposed with respect to the first electrical part 213 such that, in use, the first and second contact plates 202, 203 are in contact with the third and fourth contact plates 208, 209 to form the resonant circuit (closed) 21 1. In particular, the first electrical contact plate 202 may be in contact with one of the third and fourth electrical contact plates 208, 209, and the second electrical contact plate 203 may be in contact with the other of the electrical contact plates third and fourth 208, 209. Thus, with said approach based on contact plates, the resonant circuit 21 1 can be formed between the first and second electrical parts 213, 212 through contact-based manner.

De este modo, se puede realizar la autenticación del documento de papel 200 usando el sistema de la Figura 2a simplemente para verificar (en el dispositivo NFC 205) que el devanado especialmente configurado 201 está pegado al documento de papel 200. Su presencia puede permitir concluir que el documento 200 no es una falsificación. Su ausencia puede permitir concluir que en el documento 200 puede ser una falsificación. In this way, the authentication of the paper document 200 can be performed using the system of Figure 2a simply to verify (in the NFC 205 device) that the specially configured winding 201 is attached to the paper document 200. Its presence may allow to conclude that document 200 is not a forgery. Its absence may allow to conclude that in document 200 it may be a forgery.

La Figura 2b es una representación esquemática de cómo se pueden disponer los componentes del sistema de autenticación de la Figura 2a relativamente entre sí para hacer que el sistema de autenticación funcione. El dispositivo eléctrico 206 y el documento de papel 200 pueden disponerse uno frente al otro con caras respectivas enfrentadas de tal manera que la primera placa de contacto 202 está en contacto con una de las placas de contacto tercera y cuarta 208, 209, y la segunda placa de contacto 203 está en contacto con la otra de las placas de contacto tercera y cuarta 208, 209. La figura 2b muestra además el dispositivo NFC 205 dispuesto en la proximidad del circuito resonante 21 1 formado por la primera y segunda partes eléctricas 213, 212, de tal manera que se produce el acoplamiento inductivo y, por lo tanto, la comunicación NFC entre el elemento eléctrico inductivo 201 y el dispositivo NFC 205. Figure 2b is a schematic representation of how the authentication system components of Figure 2a can be arranged relative to each other to make the authentication system work. The electrical device 206 and the paper document 200 can be arranged facing each other with respective faces facing each other such that the first contact plate 202 is in contact with one of the third and fourth contact plates 208, 209, and the second contact plate 203 is in contact with the other of the third and fourth contact plates 208, 209. Figure 2b further shows the NFC 205 device disposed in the vicinity of the resonant circuit 21 1 formed by the first and second electrical parts 213, 212, such that coupling occurs inductive and, therefore, NFC communication between inductive electrical element 201 and NFC 205.

La Figura 3 es una representación esquemática de un sistema de autenticación de acuerdo con un ejemplo adicional. Este sistema de autenticación es similar al ¡lustrado por la Figura 2a. En particular, el sistema de autenticación de la figura 3 también se muestra comprendiendo una primera parte eléctrica 313 pegada a, por ejemplo, un documento de papel 300 a autenticar, y un dispositivo eléctrico 306 que tiene una segunda parte eléctrica 312. Figure 3 is a schematic representation of an authentication system according to an additional example. This authentication system is similar to the one illustrated by Figure 2a. In particular, the authentication system of Figure 3 is also shown comprising a first electrical part 313 attached to, for example, a paper document 300 to be authenticated, and an electrical device 306 having a second electrical part 312.

Una diferencia es que el elemento capacitivo 307 (por ejemplo, condensador) se muestra comprendido en la primera parte eléctrica 313, y el elemento inductivo 301 (por ejemplo, devanado) se muestra comprendido en la segunda parte eléctrica 312. One difference is that the capacitive element 307 (for example, capacitor) is shown comprised in the first electrical part 313, and the inductive element 301 (for example, wound) is shown comprised in the second electrical part 312.

Otra diferencia es que la primera parte eléctrica 313 se muestra comprendiendo un primer y segundo devanados 302, 303 (en lugar de las placas de contacto 202, 203 de la Figura 2a), y la segunda parte eléctrica 312 se muestra comprendiendo un tercer y cuarto devanados 308, 309 (en lugar de las placas de contacto 208, 209 de la Figura 2a). Another difference is that the first electrical part 313 is shown comprising a first and second windings 302, 303 (instead of the contact plates 202, 203 of Figure 2a), and the second electrical part 312 is shown comprising a third and fourth windings 308, 309 (instead of the contact plates 208, 209 of Figure 2a).

La primera parte eléctrica 313 y el dispositivo eléctrico 306 se muestran como elementos separados que están configurados para ser dispuestos uno respecto al otro y con respecto a un dispositivo NFC 305 de tal manera que, en uso, la primera y segunda partes eléctricas 313, 312 forman un circuito resonante (cerrado) 31 1 . El circuito resonante 31 1 se puede formar de tal manera que se produce un acoplamiento inductivo entre el dispositivo NFC 305 y el elemento eléctrico inductivo 301 . El acoplamiento inductivo se puede producir de tal manera que se produce una comunicación NFC 304 entre el elemento eléctrico inductivo 301 y el dispositivo NFC 305. Las conexiones entre el elemento capacitivo 307 y los devanados primero y segundo 302, 303 y las conexiones entre el elemento inductivo 301 y los devanados tercero y cuarto 308, 309 pueden ser tales que se forma el circuito resonante 31 1 cuando el elemento eléctrico 306 se dispone de forma adecuada con respecto a la primera parte eléctrica 313. En particular, el primer devanado eléctrico 302 se puede acoplar inductivamente con uno de los devanados eléctricos tercero y cuarto 308, 309, y el segundo devanado eléctrico 303 se puede acoplar inductivamente con el otro de los devanados eléctricos tercero y cuarto 308, 309. Por lo tanto, el circuito resonante 31 1 entre la primera y segunda partes eléctricas 313, 312 se puede formar sin contacto (contactless manner). Este enfoque sin contacto puede permitir una operación más cómoda y más rápida del sistema de autenticación. The first electrical part 313 and the electrical device 306 are shown as separate elements that are configured to be arranged relative to each other and with respect to an NFC device 305 such that, in use, the first and second electrical parts 313, 312 they form a resonant circuit (closed) 31 1. The resonant circuit 31 1 can be formed such that an inductive coupling occurs between the NFC device 305 and the inductive electrical element 301. Inductive coupling can occur in such a way that an NFC 304 communication occurs between the inductive electrical element 301 and the NFC 305 device. The connections between the capacitive element 307 and the first and second windings 302, 303 and the connections between the inductive element 301 and the third and fourth windings 308, 309 can be such that the resonant circuit 31 1 is formed when the electrical element 306 is properly disposed with respect to the first electrical part 313. In particular, the first electrical winding 302 can be inductively coupled with one of the third and fourth electrical windings 308, 309, and the second electrical winding 303 can be inductively coupled with the another of the third and fourth electric windings 308, 309. Therefore, the resonant circuit 31 1 between the first and second electrical parts 313, 312 can be formed without contact (contactless manner). This contactless approach can allow for more convenient and faster operation of the authentication system.

El dispositivo eléctrico 306 puede comprender además un circuito integrado 310 configurado para almacenar unos datos a utilizar para la autenticación del documento de papel 300. El circuito integrado 310 puede estar conectado a la segunda parte eléctrica 312 de tal manera que los datos almacenados pueden ser transmitidos al dispositivo NFC 305 a través de la comunicación NFC 304. El circuito integrado 310 (de la Figura 3) puede funcionar, por lo tanto, de la misma manera o similar al circuito integrado 210 (de la Figura 2a). The electrical device 306 may further comprise an integrated circuit 310 configured to store some data to be used for the authentication of the paper document 300. The integrated circuit 310 may be connected to the second electrical part 312 such that the stored data can be transmitted to the NFC device 305 through the NFC communication 304. The integrated circuit 310 (of Figure 3) can therefore operate in the same manner or similar to the integrated circuit 210 (of Figure 2a).

La autenticación del documento de papel 300 se puede realizar, por lo tanto, utilizando el sistema de la Figura 3 para simplemente verificar (en el dispositivo NFC 305) que el condensador especialmente configurado 307 está pegado al documento de papel 300. Su presencia puede permitir concluir que el documento 300 no es una falsificación. Su ausencia puede permitir concluir que en el documento 300 puede ser una falsificación. Authentication of the paper document 300 can therefore be performed using the system of Figure 3 to simply verify (in the NFC device 305) that the specially configured capacitor 307 is attached to the paper document 300. Its presence may allow conclude that document 300 is not a forgery. Its absence may allow to conclude that in document 300 it can be a forgery.

La Figura 4 es una representación esquemática de un sistema de autenticación de acuerdo con otro ejemplo. Este sistema de autenticación es similar al ¡lustrado en la Figura 3. El sistema de autenticación de la Figura 4 también se muestra comprendiendo una primera parte eléctrica 413 pegada a, por ejemplo, un documento de papel 400 a autenticar, y un dispositivo eléctrico 406 que tiene una segunda parte eléctrica 412. Figure 4 is a schematic representation of an authentication system according to another example. This authentication system is similar to that illustrated in Figure 3. The authentication system of Figure 4 is also shown comprising a first electrical part 413 attached to, for example, a paper document 400 to be authenticated, and an electrical device 406 having a second electrical part 412.

Una diferencia es que el elemento capacitivo 407 (por ejemplo, condensador) se muestra comprendido en la segunda parte eléctrica 412, y el elemento inductivo 401 (por ejemplo, devanado) se muestra comprendido en la primera parte eléctrica 413. One difference is that the capacitive element 407 (for example, capacitor) is shown comprised in the second electrical part 412, and the inductive element 401 (for example, winding) is shown comprised in the first electrical part 413.

La primera parte eléctrica 413 y el dispositivo eléctrico 406 también se muestran como elementos separados que están configurados para ser dispuestos uno respecto al otro y con respecto a un dispositivo NFC 405 de tal manera que, en uso, la primera y segunda partes eléctricas 413, 412 forman un circuito resonante (cerrado) 41 1 . El circuito resonante 41 1 se puede formar de tal manera que se produce un acoplamiento inductivo entre el dispositivo NFC 405 y el elemento eléctrico inductivo 401 . El acoplamiento inductivo se puede producir de tal manera que se produce una comunicación NFC 404 entre el elemento eléctrico inductivo 401 y el dispositivo NFC 405. The first electrical part 413 and the electrical device 406 are also shown as separate elements that are configured to be arranged relative to each other and with respect to an NFC device 405 such that, in use, the first and second electrical parts 413, 412 form a resonant circuit (closed) 41 1. The resonant circuit 41 1 can be formed such that an inductive coupling occurs between the NFC device 405 and the inductive electrical element 401. Inductive coupling can occur in such a way that an NFC 404 communication occurs between the inductive electrical element 401 and the NFC device 405.

Los devanados primero y segundo 402, 403 (en la primera parte eléctrica 413) y los devanados tercero y cuarto 408, 409 (en la segunda parte eléctrica 412) pueden tener el mismo rol que los devanados 302, 303, 308, 309 de la Figura 3 para implementar un acoplamiento sin contacto entre la primera y segunda partes eléctricas 413, 412. Este enfoque sin contacto puede permitir una operación más cómoda y más rápida del sistema de autenticación. The first and second windings 402, 403 (in the first electrical part 413) and the third and fourth windings 408, 409 (in the second electrical part 412) may have the same role as the windings 302, 303, 308, 309 of the Figure 3 to implement a contactless coupling between the first and second electrical parts 413, 412. This contactless approach may allow for more convenient and faster operation of the authentication system.

El dispositivo eléctrico 406 puede comprender además un circuito integrado 410 con el mismo rol o similar al del circuito integrado 310 de la Figura 3. The electrical device 406 may further comprise an integrated circuit 410 with the same role or similar to that of the integrated circuit 310 of Figure 3.

La autenticación del documento de papel 400 se puede realizar, de este modo, utilizando el sistema de la figura 4 simplemente para verificar (en el dispositivo NFC 405) que el devanado especialmente configurado 401 está pegado al documento de papel 400. Su presencia puede permitir concluir que el documento 400 no es una falsificación. Su ausencia puede permitir concluir que en el documento 400 puede ser una falsificación. Authentication of paper document 400 can thus be performed using the system of Figure 4 simply to verify (in NFC device 405) that the specially configured winding 401 is attached to paper document 400. Its presence may allow conclude that Document 400 is not a forgery. Its absence may allow to conclude that in document 400 it can be a forgery.

La Figura 5 es una representación esquemática de un sistema de autenticación de acuerdo con un ejemplo adicional. Esta configuración es similar a la configuración de la Figura 4. El sistema de autenticación de la Figura 5 se muestra también comprendiendo una primera parte eléctrica 513 pegada a, por ejemplo, un documento de papel 500 a autenticar, y un dispositivo eléctrico 506 que tiene una segunda parte eléctrica 512. Figure 5 is a schematic representation of an authentication system according to an additional example. This configuration is similar to the configuration of Figure 4. The authentication system of Figure 5 is also shown comprising a first electrical part 513 attached to, for example, a paper document 500 to be authenticated, and an electrical device 506 having a second electrical part 512.

Una diferencia es que el elemento inductivo 501 y el elemento capacitivo 507 se muestran comprendidos en la segunda parte eléctrica 512 del dispositivo eléctrico 506. Los devanados primero y segundo 502, 503 (en la primera parte eléctrica 513) y los devanados tercero y cuarto 508, 509 (en la segunda parte eléctrica 512) pueden tener el mismo rol que los devanados 402, 403, 408, 409 de la Figura 4 para implementar un acoplamiento sin contacto entre la primera y segunda partes eléctricas 513, 512. One difference is that the inductive element 501 and the capacitive element 507 are shown included in the second electrical part 512 of the electrical device 506. The first and second windings 502, 503 (in the first electrical part 513) and the third and fourth windings 508 , 509 (in the second electrical part 512) may have the same role as the windings 402, 403, 408, 409 of Figure 4 to implement a contactless coupling between the first and second electrical parts 513, 512.

Otra diferencia con respecto a la figura 4 es que el primer y segundo devanados 502, 503 están conectados "directamente" por medio de, por ejemplo, una simple pista conductora con el objetivo de cerrar el circuito resonante 51 1 cuando el dispositivo eléctrico 506 se dispone de forma adecuada con respecto a la primera parte eléctrica 513. Según los mismos principios o similares comentados con respecto a otras figuras, se puede establecer finalmente una comunicación NFC 504 entre el elemento inductivo 501 y el dispositivo NFC 505. El dispositivo eléctrico 506 puede comprender además un circuito integrado 510 con el mismo rol o similar al del circuito integrado 410 de la Figura 4. De este modo, la autenticación del documento de papel 500 se puede realizar utilizando el sistema de la Figura 5 simplemente para verificar (en el dispositivo NFC 505) que la conexión directa entre los devanados primero y segundo 502, 503 está pegada al documento de papel 500. Su presencia puede permitir concluir que el documento 500 no es una falsificación. Su ausencia puede permitir concluir que en el documento 500 puede ser una falsificación. Another difference with respect to Figure 4 is that the first and second windings 502, 503 are connected "directly" by means of, for example, a simple conductive track in order to close the resonant circuit 51 1 when the electrical device 506 is properly disposed with respect to the first electrical part 513. According to the same or similar principles discussed with respect to other figures, an NFC 504 communication can finally be established between the inductive element 501 and the NFC 505 device. The electrical device 506 can further comprising an integrated circuit 510 with the same or similar role as the integrated circuit 410 of Figure 4. Thus, the authentication of the paper document 500 can be performed using the system of Figure 5 simply to verify (in the NFC 505 device) that the direct connection between the first and second windings 502, 503 is attached to the paper document 500. Their presence may allow to conclude that document 500 is not a forgery. Its absence may allow to conclude that in document 500 it can be a forgery.

La Figura 6 es una representación esquemática de un sistema de autenticación de acuerdo con otro ejemplo adicional. Este sistema es similar al ¡lustrado en la Figura 5. El sistema de autenticación de la Figura 6 se muestra también comprendiendo una primera parte eléctrica 613 pegada a, por ejemplo, un documento de papel 600 (a autenticar), y un dispositivo eléctrico 606 que tiene una segunda parte eléctrica 612. Figure 6 is a schematic representation of an authentication system according to another additional example. This system is similar to that illustrated in Figure 5. The authentication system of Figure 6 is also shown comprising a first electrical part 613 attached to, for example, a paper document 600 (to be authenticated), and an electrical device 606 which has a second electrical part 612.

Una diferencia es que se usa una primera, segunda, tercera y cuarta placas de contacto 602, 603, 608, 609 en lugar del primer, segundo, tercero y cuarto devanados 502, 503, 508, 509 de la Figura 5. Por lo tanto, se produce una conexión mediante contacto entre la primera y segunda partes eléctricas 613, 612 para formar un circuito resonante (cerrado) 61 1 cuando el dispositivo eléctrico 606 se dispone de forma adecuada con respecto a la primera parte eléctrica 613. One difference is that a first, second, third and fourth contact plates 602, 603, 608, 609 are used instead of the first, second, third and fourth windings 502, 503, 508, 509 of Figure 5. Therefore , a connection is produced by contact between the first and second electrical parts 613, 612 to form a resonant (closed) circuit 61 1 when the electrical device 606 is properly disposed with respect to the first electrical part 613.

Como en la Figura 5, el elemento inductivo 601 y el elemento capacitivo 607 también se muestran conectados de forma adecuada dentro de la segunda parte eléctrica 612 del dispositivo eléctrico 606. As in Figure 5, the inductive element 601 and the capacitive element 607 are also shown properly connected within the second electrical part 612 of the electrical device 606.

Las placas de contacto primera y segunda 602, 603 están conectadas "directamente" por medio de, por ejemplo, una pista conductora con el objetivo de cerrar el circuito resonante 61 1 cuando el dispositivo eléctrico 606 se dispone de forma adecuada con respecto a la primera parte eléctrica 613. Según los mismos principios o similares comentados con respecto a otras figuras, se puede establecer finalmente una comunicación NFC 604 entre el elemento inductivo 601 y el dispositivo NFC 605. The first and second contact plates 602, 603 are connected "directly" by means of, for example, a conductive track in order to close the resonant circuit 61 1 when the electrical device 606 is properly disposed with respect to the first electrical part 613. According to the same or similar principles discussed with respect to others figures, an NFC 604 communication can finally be established between the inductive element 601 and the NFC 605 device.

El dispositivo eléctrico 606 puede comprender además un circuito integrado 610 con el mismo rol o similar al del circuito integrado 510 de la Figura 5. The electrical device 606 may further comprise an integrated circuit 610 with the same role or similar to that of the integrated circuit 510 of Figure 5.

La autenticación del documento de papel 600 se puede realizar, por lo tanto, utilizando el sistema de la Figura 6 simplemente para verificar (en el dispositivo NFC 605) que la conexión directa entre las placas de contacto primera y segunda 602, 603 está pegada al documento de papel 600. Su presencia puede permitir concluir que el documento 600 no es una falsificación. Su ausencia puede permitir concluir que el documento 600 puede ser una falsificación. Aunque sólo se han descrito un número de ejemplos en este documento, son posibles otras alternativas, modificaciones, usos y/o equivalentes de los mismos. Además, también se cubren todas las combinaciones posibles de los ejemplos descritos. De este modo, el alcance de la presente descripción no debe estar limitado por los ejemplos particulares, sino que debería determinarse sólo por una lectura imparcial de las reivindicaciones que siguen. Authentication of the paper document 600 can therefore be performed using the system of Figure 6 simply to verify (in the NFC 605 device) that the direct connection between the first and second contact plates 602, 603 is attached to the paper document 600. Its presence may allow to conclude that document 600 is not a forgery. Its absence may allow to conclude that document 600 may be a forgery. Although only a number of examples have been described in this document, other alternatives, modifications, uses and / or equivalents thereof are possible. In addition, all possible combinations of the described examples are also covered. Thus, the scope of the present description should not be limited by the particular examples, but should be determined only by an impartial reading of the claims that follow.
