摘要： An imaging device includes a transparent prismatic element having two contiguous inlet surfaces separated by a ridge. A lens and an image sensor make it possible to acquire images, each including a reproduction of a first pattern located against one of the inlet surfaces, and a reproduction of a second imaged pattern through the other inlet surface. Such a device can be used in a biometric detection apparatus for detecting both a skin print and the vein distribution of a user. The device can also be used in a reading terminal capable of detecting a skin print and a machine-readable tape.

摘要： A device is provided that generates a composite image using a first image and a second image having different exposure conditions. The device includes an image input unit, a likelihood calculating unit, an exposure estimating unit, and a compositing unit. The image input unit inputs the first image and the second image. The likelihood calculating unit calculates a subject motion likelihood at each pixel based on a difference between the first image and the second image. The exposure estimating unit estimates an exposure transform function that conforms the exposure conditions of the first image and the second image to each other based on the subject motion likelihood. The compositing unit composites the first image and the second image by using the exposure transform function.

摘要： A database comprising biometric data stored in encrypted form is managed by a management unit. It comprises a set of filters respectively associated with filter identifiers. A biometric data item is received at a management unit; next, said biometric data item is stored in an encrypted form at a given address in the database. Then keywords are obtained on the basis of a first set of hash functions and of the biometric data item. A subset of indexing filters is associated with each keyword by selecting, for each keyword, filters as a function of the respectively associated filter identifiers, of said keywords, and of a second set of hash functions; and the given address is associated with each of the filters of the subset of filters.

摘要： A security gate has two walls defining between them a passage through which an individual passes, for each wall, a transparent lighting window extending over at least part of the wall, for at least one of the edges of the lighting window, a light source intended to light the edge and to generate light beams that propagate through the thickness of the lighting window, and for each lighting window, at least one extraction zone provided on the lighting window and intended to transmit the light beams towards the face of the individual passing through the passage, the light beams thus transmitted forming, with respect to the plane of the lighting window from which they emanate, an angle adapted to the geometry of the security gate so as to optimize the lighting of the individual.

摘要： The invention concerns a method for executing cryptographic calculation in an electronic component, based on a specific cryptographic algorithm including at least one secret key operation (102) to be performed with a secret encryption key (103) comprising m secret encryption key blocks of n bits on a data block (101), wherein m and n are positive integers, and a non-linear operation (107). It consists in determining 2n−1 secondary secret keys (105) on n bits different from the secret encryption key block; then, for a given secret encryption key block, performing the secret key operation (102) with the secret encryption key block (103) and performing the secret key operation (102) with the secondary secret keys on a data block (101) and obtaining respectively a data block being encrypted (104) and 2n−1 secondary data blocks (106); then performing the non-linear operation (107) of the data block being encrypted (104) and on the secondary blocks (106); supplying data block encrypted from the data block being encrypted.

摘要： A sampling system that contains filter components for collecting and concentrating vapor and particles in high-volume flows. The sample is then vaporized and delivered to a detector at a low-volume flow. The invention also has a sampling probe that contains an air-jet to help dislodge particles from surfaces and a heating lamp to help vaporize compounds on surfaces or objects. The sampling system is especially useful for screening for explosives and other illicit chemicals and toxins on people, baggage, cargo, and other objects.
