Abstract: Disclosed is a fraud detection method to authenticate that an object is formed of human skin. The method includes an object being placed on a home location on the surface of a propagation medium of a sensor, lighting the home location of the surface by a light source emitting light rays illuminating the home location forming with said surface a plurality of incidence angles encompassing a critical angle defined by the refraction index of the propagation medium and by a refraction index expected for authentic human skin, receipt by an imager of light rays from the surface, and acquisition of an image, and determining whether the object matches an authentic human finger based on the refraction index of said object, as a function of the spatial light distribution on the acquired image.

Abstract: A method of recognizing individuals by means of at least one processor executing a recognition algorithm comprising the steps of: detecting biometric characteristics of a finger of a candidate for recognition while writing a signature by pressing the finger against a signature surface; encoding both the written signature and also the biometric characteristics in order to form signature data and biometric data of the candidate; and using the algorithm to compare the signature data and the biometric data of the candidate with signature data and fingerprint biometric data belonging to at least one individual and stored on a data medium.

Abstract: The invention relates to a fraud detection method to authenticate that an object is formed of human skin, said object (5) being placed on a home location on the surface (3) of a propagation medium (2) of a sensor (1), which method comprises the following steps: lighting the home location of the surface (3) by a light source (6) emitting light rays (20, 22) illuminating the home location forming with said surface a plurality of incidence angles encompassing a critical angle defined by the refraction index of the propagation medium and by a refraction index expected for authentic human skin, receipt by an imager (4) of light rays from the surface (3), and acquisition of an image, determining whether the object (5) matches an authentic human finger based on the refraction index of said object, as a function of the spatial light distribution on the acquired image.

Abstract: The invention concerns a size marker for electrophoresis, characterized in that it contains several pairs of molecules the sizes of which are selected to allow the generation of a succession of double-peaks in one same electropherogram, said double-peaks being spaced apart two by two by a distance greater than the distance separating the two peaks of a double-peak. The invention also concerns a method for controlling the resolution of an electropherogram produced with a said marker.

Abstract: The present invention relates to a PCR kit for improving detection of particular nucleic acid motifs and for increasing the reliability of the results obtained. More precisely, the invention proposes to use modified primers having particular characteristics making it possible, during electrophoresis treatment, to detect, on samples containing nucleic acids, the equivalent of a characteristic encoding of particular nucleic acid motifs, this encoding being such that it makes it possible to better detect the presence of these motifs. The invention also proposes a method for detecting nucleic acid motifs of interest (for example STRs, mini-STRs or VNTRs) using such primers. It advantageously finds—but is not limited to—application in the field of capillary electrophoresis.

Abstract: The invention relates to a process for digitizing document in which the document (4) is feed driven in front of a sensor (2) by a drive mechanism (3) comprising a plurality of elements (31-36) which come into contact with the document (4) while it is fed, wherein the sensor (2) is capable of generating digital data from an image on the document (4), wherein the process comprises steps consisting of: —detecting when the contact is established or broken between the document (4) and one of the elements (32), —correcting the digital data by applying to the data a distortion correction function which takes into account the position of the sensor (2) with respect to the image when the detection takes place.
