A system for acquiring an image of veins of a finger includes a camera designed to acquire an image of said finger when it is passed in front of it, a lighting device designed to illuminate said finger and a control unit for controlling the illumination intensity of said lighting device. Also, at least one system measures the transmission power of said finger upstream of the camera with respect to the passage of said finger towards said camera, said control unit being designed to control the illumination intensity of said lighting device according to the transmission power measured by said measuring system. Additionally, a method for acquiring images of veins of a finger is provided.

The invention relates to a device for acquisition of images for a biometric system, which includes an optical assembly and at least one imager for acquisition of an image of an object to be analysed presented in front of the assembly at a non-determined distance from the latter. The assembly includes at least one diaphragm with a coded aperture. The optical assembly allows acquisition by the sensor(s) of an image of the object capable of being exploited to deduce therefrom the searched biometric information, and of an image of the object acquired via the coded aperture of the diaphragm. The device also includes a processing unit to determine the distance of the object to be analysed as a function of the image of the object acquired via the coded aperture of the diaphragm.


A method of detecting zones liable to contain at least one finger print in an image of at least one portion of hand of an individual includes a step of acquiring the image, a step of determining a plurality of zones of the acquired image and a first selection step. The step of determining a plurality of zones determines that each zone is a continuous zone of points of the acquired image which each exhibit a luminous intensity level greater than or equal to a selected luminous intensity threshold value. The first selection step selects, from among the zones determined, the zones which are liable to represent at least one print of a finger.


A device for use in identifying or authenticating a subject positioned in an acquisition volume on the basis of at least one biometric characteristic of the subject, the device including in succession, in offset manner along a camera placement axis: a first camera; a second camera; and a third camera; the optical axes of the first and second cameras forming between them an angle strictly less than 10, and the optical axis of the third camera intersecting the optical axes of the first and second cameras, the optical axes of the first and second cameras each forming an angle less than or equal to 5 relative to a normal axis perpendicular to the camera placement axis.

The increase of the identity theft phenomenon across Europe and its related human and economical impacts is a major concern for all M.S. Several EU initiatives are ongoing to try to curb this concern. Todays identity can take various forms, either in the real world, as a primary identity delivered by a M.S. (passport, ID card, driving license...) but more and more in the 2.0 world (secondary identity for banking, administration, professional and commercial activities...). Similarly identity theft can take various forms, from stealing citizens paper documents, or simply by using digital means. Privacy is at the center of all concerns, as any solution must protect citizens identity and privacy, whilst not being worse than the problem itself. The major objective of EKSISTENZ is to protect EU citizens identities from all current threats but also to foresee what the future threats would be. The project will study in deep the identity theft phenomenon in Europe, revealing the flaws in the different paper-based procedures but also in the new dematerialized processes, assess the threat for the citizen and consequently, will develop technological components, backward compatible with different existing M.S. frameworks. EKSISTENZ will also focus on an identity-as-a-service approach, to allow M.S. interoperability, leading to a more global system to provide secure and strong identity for all M.S. To achieve this, the consortium will bring together different types of users involved in the identity chain (authorities, industrials, stakeholders, businesses), specialized technology providers and of course, data protection and privacy experts. EKSISTENZ will recommend updates to EU regulations in order to clearly inform, protect, propose responses and increase its resilience following an attempt. Knowing this, identity theft will become, if not impossible, much harder to carry out.
