Abstract
The invention relates to an application and a method for checking documents. Hitherto, documents with optical diffraction security layers, specially holograms, were checked by costly optical monitoring technology. The entire monitoring process was so time-consuming that the monitoring process could not be applied to fast operating processing machines. Rapid monitoring (as an authentication characteristic) constitutes a further security step in evaluating effective optical diffraction security layers. The effective optical diffraction layer has a discontinuous metallizing layer and/or partially metal layers and/or areas of metal layers on various planes. Several methods of measurement exist to detect electrical conductivity. In practice, the contactless capacitive method of measurement has proven to be more practical.
Description
The present invention relates to the application and the method for checking file.
Up to now, have the safe floor (diffraction-opticallyeffective safety layers) of diffraction optics effect, the file that particularly has hologram is to adopt costly optical evaluation facility to test.In this case, the check thing must accurately be located.The one-hundred-percent inspection process is for a long time consuming time, so that this method of inspection can not be used in the fast processing machine.For example, the banknote that has the holographic false proof sign just can not be tested in paper money counter, because this paper money counter is with per minute 500 and 1500 be higher than this speed operation.DE2747156 has introduced method and the testing instruments that the I.D. that adopts hologram is carried out validity check.This hologram is copied and estimated.This method is not suitable for carrying out fast, effectively, not depending on people's check.Introduced a kind of device that produces scanning patter in EP0042946, this device is to test by means of laser, reflective optics and lens combination and optical sensor.Required in this case expense is also very high.If the check thing does not carry out classification and Detection, expense can be higher.For avoiding classifying in advance, false proof checking system needs multi-level the layout.
The objective of the invention is to overcome the defective of prior art and propose fast, not depend on the people's and with cheap expense to having effective optical diffraction security layer, particularly have application and method that the file of hologram is tested.This method both can also can be tested to the file that has effective optical diffraction security layer in hand-held testing instruments in device for verifying documents and cash processing machine device.
This purpose is achieved by feature given in claim 1 characteristic.
Adopting hologram and other effective optical diffraction security layer to carry out false proof to certificate and other securities and banknote is method more and more commonly used at present.Quick test also is the other safe class when the effective optical diffraction layer of identifying as anti-false sign.The effective optical diffraction layer is made up of a metal layer and other materials.This metal layer has electric conductivity.Conductive capability is according to the bed thickness respective change.The effective optical diffraction floor has an interrupted metal layer and/or the metal level district on localized metallic floor and/or the Different Plane.The known method that different measurement electric conductivity is arranged.Facts have proved that this non-contact capacitance mensuration is feasible.In the method for this checking security documents, the transmission of energy utilizes the conductive security material to carry out the electromagnetic field overlap joint between capacitive coupling between transmitter and the receiver and transmitter and the receiver.Electronic analysis device subsequently will check the signal pattern of thing and corresponding reference signal to compare.This relatively provides the category signal of further processing.Corresponding therewith, for example verifying attachment can be shut down at this moment and the file that will be identified as counterfeit money sorts out.Signal pattern depends on the structure of the metal layer of effective optical diffraction layer.If the effective optical diffraction layer has an interrupted metal layer, each zone of metal layer has different electric conductivity so.Practice shows that this different electric conductivity is had an effect to signal pattern.
Electric conductivity combined with other anti-false sign of effective optical diffraction layer test, can further improve the reliability of check.Additional anti-false sign can be checked this sign and electric conductivity simultaneously in the non-metallic zone between the metal level zone on interrupted metal layer and/or localized metallic layer and/or Different Plane.By the electronic analysis device, the authenticity signal of measuring another sensor of authenticity is connected with the sensor logic of measuring electric conductivity.At the output terminal of electronic analysis device, one waits for effective optical diffraction layer classified signals and is for further processing.Should have fluorescigenic, phosphorescent or light absorbing characteristic by additional anti-false sign, or come by different magnetic and the difference of its environment.Corresponding therewith, use optics or magnetic sensor.Detect and measuring error for reducing, preferably use the sensor carrier member.This sensor carrier member can be held all the sensors that is used to detect anti-false sign.Also make distance between the sensor minimize and sensor is arranged in definite position all the time.Be the factor of avoiding interference, the sensor carrier member firmly is connected with supporting electronic analysis Unit Installation plate.Whole verifying attachment is contained in the handling machine, thereby needn't increase the additional expense of transporting the check thing.
Except claim, explanatory note and accompanying drawing also can show feature of the present invention, and each feature has been represented the claimed embodiment with advantage and patentability here with independent form or several forms that makes up respectively respectively.Be one embodiment of the present of invention shown in the figure, describe the present invention in detail below with reference to this embodiment.In the accompanying drawing:
