    摘要: A method for identifying and/or authenticating an individual by a system including a storage device storing at least one binary code of a reference iris and a binary code of an associated reference mask: acquisition of an image of an eye of the individual, segmentation of the acquired image to isolate a region containing the texture of the iris and determine an associated mask, division of the region and the mask into N2 concentric rings, normalization of the region, determination of a binary iris code IC and a binary code of mask IM matching at least one ring of the iris with a ring of the reference iris to minimize a matching distance between the acquired image and the reference image, computation of the minimized matching distance, identification and/or authentication of the individual if the minimized matching distance is less than a predetermined threshold.

    摘要: A method for verifying identity of a user of a communicating terminal, including: a preliminary operation including: communicating a first piece of identity data of a user to at least one server, generating a second piece of identity data of the user from the server, the second piece of data defining a derived identity of the user, and storing the second piece of identity data in a secure memory of the terminal; an operation for identity verification, including: transmitting a token for encryption from the server to the terminal, using the second piece of data at the terminal at least to generate an encryption of the token, the encrypted token being transmitted to the server and verified by the server, and in a case of positive verification of the encrypted token by the server, the server validates the identity verification of the user of the terminal.

    摘要: A cryptographic calculation includes obtaining a point P(X,Y) from a parameter t on an elliptical curve Y2=f(X); and from polynomials X1(t), X2(t), X3(t) and U(t) satisfying: f(X1(t))·f(X2(t))·f(X3(t))=U(t)2 in Fq, with q=3 mod 4. Firstly a value of the parameter t is obtained. Next, the point P is determined by: (i) calculating X1=X1(t), X2=X2(t), X3=X3(t) and U=U(t); (ii) if the term f(X1)·f(X2) is a square, then testing whether the term f(X3) is a square in Fq and if so calculating the square root of f(X3) in order to obtain the point P(X3); (iii) otherwise, testing whether the term f(X1) is a square and, if so, calculating the square root of f(X1) in order to obtain the point P(X1); (iv) otherwise, calculating the square root of f(X2) in order to obtain the point P(X2). This point P is useful in a cryptographic application.

    摘要: The invention relates to a method for calibrating a sighting system comprising a viewfinder and an optic for detecting the position of an object in space, characterized in that it comprises the determination of a control law to apply to the viewfinder to aim at the object as a function of its position, said position being determined in a frame of reference of the detection optic and the control law comprising two angular controls and a focusing control of the viewfinder, expressed as a function of the relative positions between the object to aim at and an intersection point of all the lines of sight of the viewfinder, the method comprising the steps consisting in: aiming (100), with the viewfinder, at objects found at at least six different known positions in the frame of reference of the sighting system and noting the corresponding controls, from the positions of the object and the corresponding controls, determining (200, 200′) the position of the intersection point of the lines of sight and the control law by the minimization of a function of the second derivative of the control law.

    摘要: The invention relates to a method of inputting confidential data on a terminal including an input interface, at least one processor for running a trusted program and a display screen, the method including the following steps applied before the input: taking exclusive control of the input interface by the trusted program; displaying on the screen a trusted image known to the user of the terminal to indicate that exclusive control of the input interface has been taken by the trusted program; after control has been taken and before displaying the trusted image, selecting the trusted image as part of a reference image predetermined by the user, wherein the selected trusted image varies from one input to another. The invention also relates to a terminal for use of said method.

    摘要: An image processing device is provided. The image processing device includes: a tracking area setting section that sets a tracking area in a frame image of an original motion picture; a color information obtaining section that obtains color information of the tracking area set by the tracking area setting section; a tracking position estimating section that estimates a tracking position with reference to the tracking area with respect to each frame image of the original motion picture by using the color information obtained by the color information obtaining section; an output frame setting section that sets an output frame enclosing the tracking area set by the tracking area setting section and that updates the output frame based on the estimated tracking position; and a lock-on motion picture generating section that generates a motion picture that is based on the output frame.
