Abstract

The smart card includes a number of biometric characteristic data sets in addition to the normal digital coding. In particular the written signature of the holder is digitized as is a sample of speech. Fingerprint data is also entered into memory. When the card is entered into a reader the data is transferred to a computer for processing.

Description

Chipkarten (Smartcard) sind allgemein bekannt. Sie werden für viele Anwendungen genutzt. Beispiele hierfür sind Kreditkarte, Scheckkarte, Telefonkarte, Arztkarte, etc. Für die "digitale Signatur" wird ebenfalls eine Chipkarte zur Anwendung kommen. In dem Halbleiterchip, einem Mikroprozessor, werden viele Funktionen realisiert. So z. B. die Speicherung von Kryptoalgorithmen, persönliche Daten des Inhabers und Daten der Ausgabestelle. Es werden dort aber auch biometrische Merkmale des Be­ sitzers gespeichert.Smart cards are generally known. They are used for many applications utilized. Examples of this are credit card, check card, phone card, doctor card, etc. A chip card will also be used for the "digital signature". In The semiconductor chip, a microprocessor, performs many functions. So e.g. B. the storage of crypto-algorithms, personal data of the owner and Issuing office data. There are also biometric features of the Be saved.

Gerade bei der "digitalen Signatur" werden erhebliche Anforderungen an den Identi­ tätsnachweis des Besitzers der Chipkarte gestellt. Erst durch die eindeutige Identifi­ zierung des Nutzers ist eine juristische Anerkennung der "digitalen Signatur" möglich. Die erheblichen Schwächen der Personenidentifikationsnummern (PIN) und Codes - nicht nur in deren Verschlüsselung, vielmehr in dem Problem mit deren Umgang­ verlangen die Identifizieung des Besitzers durch biometrische Merkmale.Especially with the "digital signature" there are considerable demands on the identi Proof of the identity of the owner of the chip card. Only through the clear identification The user is legally recognized for the "digital signature". The significant weaknesses of personal identification numbers (PIN) and codes - not only in their encryption, but rather in the problem with their handling require the owner to be identified by biometric features.

Hierzu bietet sich besonders die vierdimensional erfaßte Unterschrift an. Diese ist man gewohnt und wird in unserem Kulturkreis allgemein akzeptiert. Wie M. Hecker vom BKA Wiesbaden in seinem Buch "Forensische Handschriftuntersuchung" (Krimi­ nalistikverlag, Heidelberg, 1993) ausführt: "Die Unterschrift als Ausdruck einer Handlung 'mit seinem Namen für etwas zu stehen', hat nach wie vor große Bedeu­ tung im Rechtsleben."The four-dimensional signature is particularly useful for this. This is you are used to and generally accepted in our culture. Like M. Hecker from the BKA Wiesbaden in his book "Forensic handwriting examination" (crime thriller nalistikverlag, Heidelberg, 1993) explains: "The signature as an expression of a Action 'to stand for something with his name' is still very important tion in legal life. "

Unterschriftenprüfer sind bekannt. Dabei erfolgt die Aufnahme der Schriftdynamik mit Spezialstiften auf einem Digitalisiertablett oder mit Normalstiften auf einer mit Wäge­ zellen unterbauten Platte. Die biometrischen Merkmale der Unterschrift können dann auf der Chipkarte gespeichert werden. Siehe EP 0 560 356.Signature checkers are known. The writing dynamics are recorded with Special pens on a digitizing tablet or with normal pens on a scale cells under plate. The signature's biometric features can then be saved on the chip card. See EP 0 560 356.

Die Stimmerkennung ist ebenfalls bekannt. Hierzu wird ein vorgewähltes und in ein Mikrofon gesprochenes Paßwort als biometrisches Merkmal genutzt.Voice recognition is also known. For this, a preselected and in a Microphone spoken password used as a biometric feature.

Die Abgabe eines Fingerabdruckes erfolgt in eine Fläche die die Abtastung der Tastlinien übernimmt. Diese stehen ebenfalls als Halbleiterchip zur Verfügung.A fingerprint is given in an area that is scanned Touch lines takes over. These are also available as semiconductor chips.

Der Nachteil dieser Verfahren liegt darin begründet, daß die Aufnahme der Schreib­ dynamik, der Stimmfrequenzen und der Tastlinien jeweils in einem gesonderten Ge­ rät erfolgt, also immer getrennt von dem Chipkartenleser und Chipkarte. Gezwunge­ nermaßen muß eine elektrische Verbindung zwischen dem Aufnahmegerät und dem Chipkartenleser vorhanden sein. Diese dient der Datenübertragung der zu spei­ chernden oder gespeicherten biometrischen Merkmale in dem Chip.The disadvantage of this method is that the inclusion of the letter dynamics, the voice frequencies and the tactile lines each in a separate Ge advises, so always separate from the smart card reader and smart card. Forced In particular, an electrical connection between the recording device and the Smart card reader must be available. This is used to transmit the data saving or stored biometric features in the chip.

Werden die Daten benötigt, müssen sie wieder von der Chipkarte in das Aufnahme­ gerät überspielt werden, wo dann der Vergleich stattfindet.If the data is required, it must be transferred from the chip card back into the slot device, where the comparison then takes place.

Hier ist eine Schwachstelle, die u. U. zu Manipulationen mit betrügerischen Absichten, dem sogenannten "spoofing", ausgenutzt werden kann.Here is a vulnerability that u. U. manipulation with fraudulent intentions, the so-called "spoofing" can be used.

Erfindungsgemäß bietet es sich an, den Unterschriftenprüfer in Kombination mit ei­ nem Mikrofon, einem Fingerabdrucknehmer und der Chipkarte aufzubauen. In der Chipkarte, die ggfs. aus mehreren Lagen verschiedener Materialien erstellt ist, sind z. B. jeweils in den Ecken Wägezellen integriert. Diese messen den Druck den das Schreibutensil beim Schreiben auf der Schreibfläche ausübt. Die Änderungen der Schreibdynamik während der Leistung einer Unterschrift werden erfaßt und ausge­ wertet. According to the invention it makes sense to use the signature checker in combination with egg a microphone, a fingerprint reader and the chip card. In the Chip card, which may be created from several layers of different materials e.g. B. Load cells integrated in the corners. These measure the pressure that the Exercises writing utensils when writing on the writing surface. The changes in Writing dynamics during the performance of a signature are recorded and output evaluates.  

Desgleichen ist ein miniaturisiertes Mikrofon in die Chipkarte eingelassen, das der Stimmaufnahme dient.Likewise, a miniaturized microphone is embedded in the chip card, which the Voice recording serves.

Die schon heute vorhandenen aus Halbleitern gefertigten Aufnehmer für einen gan­ zen oder von Teilen eines Fingerabdruckes ermöglichen ebenfalls den Einbau in ei­ ner Chipkarte.The sensors that are already made of semiconductors for one go Zen or parts of a fingerprint also allow installation in an egg a chip card.

Je nach Sensibilität des zu schützenden Objekts wird vom Nutzer ein vorgewähltes Verfahren eingesetzt. So ist denkbar bei Zutrittskontrollen zu Räumen mit niederen Sicherheitsniveau den Fingerabdruck oder die Stimme zu nutzen.Depending on the sensitivity of the object to be protected, the user selects a pre-selected one Process used. It is conceivable for access controls to rooms with low levels Security level to use your fingerprint or voice.

Verlangt das zu schützende Objekt, ein Dokument, oder die Datei eine hohe Sicher­ heitsstufe, kommt nur die aktive Willenserklärung durch eine Unterschrift in Frage.Requires the object to be protected, a document, or the file a high level of security level, only the active declaration of intent through a signature comes into question.

Die Leistung einer Unterschrift, die Abgabe einer Stimmprobe oder die Prüfung des Fingerabdruckes erfolgt dann auf der Chipkarte selbst, die elektrischen Verbindun­ gen sind lediglich auf der Chipkarte vorhanden. Der Vergleich der geleisteten Unter­ schrift, der Stimmprobe oder des Fingerabdruckes mit dem auf dem Chip gespei­ cherten Daten erfolgt ohne Eingriffsmöglichkeiten von außen.The performance of a signature, the submission of a voice test or the examination of the The fingerprint is then made on the chip card itself, the electrical connections conditions are only available on the chip card. The comparison of the performed sub writing, the voice test or the fingerprint with the saved on the chip Saved data is done without external intervention.

Die Weitergabe eines Signals "erkannt" oder "nicht erkannt" in ein übergeordnetes Rechnersystem erfolgt verschlüsselt in bekannter Weise kontaktlos, kontaktbehaftet oder in einer Kombination beider Verfahren.The transmission of a signal "recognized" or "not recognized" in a higher-level Computer system is encrypted in a known manner without contact, with contact or in a combination of both methods.

Hierzu wird die Chipkarte am Ort der Abgabe des biometrischen Merkmals auf ein gekennzeichnetes Feld gelegt oder in einen üblichen Chipkartenleser eingeführt. In diesem Feld oder Chipkartenleser sind die benötigten Vorrichtungen zum Datenaus­ tausch mit dem übergeordneten Rechner integriert.For this purpose, the chip card is placed on the place of delivery of the biometric feature marked field or inserted into a conventional smart card reader. In This field or chip card reader are the devices required for data transmission exchange integrated with the higher-level computer.

Durch die Anordnung von z. B. vier Wägezellen in der Chipkarte und der entspre­ chenden Software, ist jederzeit die Stelle einer Druckeingabe bekannt. Somit können auf der Chipkarte Felder mit Zahlen oder Buchstaben versehen werden, die nach ge­ zielter Druckeingabe genau erkannt werden. Dies ermöglicht die Eingabe von bisher üblichen PIN und Codes oder dienen der Kommunikation des Nutzers mit dem über­ geordneten Rechner.By arranging z. B. four load cells in the chip card and the correspond appropriate software, the place of a print entry is known at all times. So you can Fields with numbers or letters are provided on the chip card, which according to ge targeted printing input can be precisely recognized. This enables the entry of so far usual PIN and codes or serve the communication of the user with the orderly calculator.
