Abstract: A method to conduct fingerprint verification provides a sector distribution based on the position and angle of every minutiae vector, wherein the number of further minutiae vectors of the template in any sector of the sector distribution is determined and a feature vector is generated for every minutiae vector of both templates. The two feature arrays are matched by calculating the scalar product for every combination of said vectors generating a matrix. Mated pairs of minutiae from the first second template are found by searching the maximum element in every column of the matrix finally issuing a value representing identification information of the fingerprint. Additionally a false finger identification method and a fingerprint verification system are disclosed.

Abstract: A method for setting up a secure communication line between a user and a service provider using non-secure communication channels within an insecure network, comprising the steps of transmitting an identity token from a user station to a service provider station both coupled to the insecure network; upon reception of the identity token, triggering the creation of a secret URL by the service provider station; transmitting the secret URL within a secure side channel to the user station; obtaining, within the user station, the secret URL, and setting-up a new communication path in the insecure network linking the user and the service provider station based on said secret URL. Beside discarding a man-in-the-middle by denying him access to the data flow it is also possible to stop him through denying him access to the content of the data flow. Such access can be denied through use of a one-time codebook with semantics only known to the User and the authentication service provider.

Abstract: A method for coded-aperture imaging includes the steps of providing an image containing coded information, convoluting said image with an aperture code to obtain a light emitting intermediate image, and subjecting the light emitting intermediate image to decoding mask means to obtain an image on detector means. This method can take advantage of the use of photo detectors which can easily be integrated on silicon, allowing all together to construct an extremely small camera to reconstitute a computer generated convoluted image.
