    Abstract: A system for authenticating a subject identification document includes a memory section storing computer-executable instructions and a memory section storing an enrolled document template, ROI information, and a codebook representing partitions of a [Cb, Cr] color plane. The system includes a processor in communication with the memory. The processor executes the instructions that, when executed, cause the processor to receive an image of the document, the image depicting, in a RGB color space, the document. The processor transforms the image of the document to a second image of the document in a YCbCr color space. The processor assigns pixels within a ROI in the second image corresponding to the ROI information to the partitions of the codebook. The processor generates a template based on respective counts of the pixels assigned to the partitions of the codebook. The processor compares the template to the enrolled document template to authenticate document.

    Abstract: A method for comparing a first and a second databases to determine whether an individual is represented by both an element of the first database and an element of the second database, wherein said elements are biometric data, including the implementation of the steps applying a classification model for each element of each database so as to construct a set of first and second bins of the respective first and second databases, each bin bringing together similar elements, each first bin being associated with a second bin; comparing the elements from the first database for at least one pair of an associated first bin and second bin belonging to said first bin with the elements from the second database belonging to said second bin, at least one of the first and the second databases then being encrypted homomorphically.

    Abstract: The invention relates to a contactless device (1) for capturing a biometric print, said device comprising a user region (10) and an electronic compartment (20), the user region (10) being suitable for receiving a hand portion of a user according to an orientation vector (V), the electronic compartment (20) comprising lighting means and an image-acquiring device (40), the image-acquiring device (40) being oriented along an optical axis (A1) making a first angle (B1) to the orientation vector (V), the lighting means comprising a light source (31) oriented along a lighting axis (A31) such that the projection (PA31) of said lighting axis (A31) in the plane defined by the orientation vector (V) and the optical axis (A1) makes a second angle (B31) to the orientation vector (V), the first angle (B1) being smaller than or equal to eighty degrees, the second angle (B31) being smaller than or equal to eighty degrees.

    Abstract: A method for strong authentication of an individual by a server and a connected client device, the client device having a candidate biometric data of the individual and an image from an identity document representing at least one photograph of the individual and one optical reader data visible on the identity document. A cryptographic footprint includes extracting, by analysis of the acquired image and the optical reader data, calculating a first data decoded by application of a decoding process to the candidate information and to a first encoded data, such that the first decoded data matches first random data if the candidate information matches a reference information representative of the appearance of the photograph, verifying that a cryptographic footprint of a first concatenation of the extracted optical reader data and the decoded data coincides with the first cryptographic footprint, and a reference biometric data and the candidate biometric data match.
