  • Publication number: 20130161387
    Abstract: Methods of generating a secured printed document on paper or other medium by printing a security layer made of a transparent conductive material over the ink/toner layer that forms the visible content of the document. The security layer is printed using a transparent conductive material such as transparent conductive toner or ink and is invisible to human eyes. In one embodiment, the transparent conductive material contains a pattern that forms a radio frequency (RF) transponder circuit which has an RF antenna and a digital memory storing security data, which can be read out and used to authenticate the document. In another embodiment, the pattern forms a memory circuit without an RF antenna. In yet another embodiment, the transparent conductive material is patterned but does not form a functional circuit, and the electrical properties of the security layer such conductivity and/or capacitance are used to authenticate the document.

    Abstract: In a method of controlling the operation of a security module, wherein firmware controlling the operation of the security module (10) is stored in a program memory (40), new firmware may be loaded into the module (10). An authentication key (KA) is encrypted using a key storage key (KSK) stored in a resettable shift register (54) in the security module and the encrypted authentication key is stored in a secure memory (36). A firmware authentication value FAV is calculated, using the authentication key (KA), externally of the security module (10), for the new firmware, and the new firmware, together with FAV is loaded into a data memory (38) in the security module (10). A processor (30) in the security module (10) recalculates the firmware authentication value using the stored authentication key (KA) and compares the recalculated value with the loaded value FAV. If a correct comparison is achieved, the new firmware is transferred into the program memory (40).

  • Patent number: 4344135
    Abstract: In order to verify the authenticity of the signature of an individual, first a sample signature is written with a pen which can generate electrical signals representative of the forces exerted in the plane of the paper in the process of writing. These signals are sampled and then scaled so that the signature when displayed, can be fitted within a predetermined display area. The scaled signals generated from the sample signature are then stored. When it is desired to compare the sample signature with a signature which is subsequently written, called a specimen signature, the specimen signature is written and is processed for display in the same manner as was the sample signature. The scaled sample signature signals are then called out of storage and displayed, as are the scaled signals generated in the course of writing the specimen signature. Any deviations between the signatures are very readily detectable by observing the display.

  • Patent number: 4071741
    Abstract: A validator for a card bearing a code readable by moving the card forward past a reader, particularly for use in a vendor to control vending, in which the card is transported forward from an entry position past the reader to an escrow position. If read as valid, the card is maintained in the escrow position pending the user's decision to have the card collected or to obtain return of his card. If the card is read as invalid, it is immediately fed back to the user. The card transport is such as to prevent a valid card from being pulled back out of the validator as by a string or tape attached to the card, and the validator is so constructed that it is easily opened for servicing, including removal of a card which may become jammed in the validator.
