Abstract: A method for biometrically recognizing individuals, comprising the following steps: performing at least two biometric recognitions based on separate sets of biometric characteristics detected on an individual during at least one first and one second detection operations; detecting a third set of biometric characteristics during the first detection and a fourth set of biometric characteristics during the second detection; verifying that the third set of biometric characteristics matches the fourth set of biometric characteristics. A corresponding enrolment method and a device to implement these methods.

Abstract: An image processor device includes a computer processor unit (CPU), at least one memory connected to the CPU, and device for transferring images to the CPU. The memory contains an image-processing program for processing images showing at least one person. The program performs the following operations: detecting at least a face in each image and extracting therefrom a biometric template of the face; for each image, storing in a database an image reference, the biometric template, and if possible context information for the image; comparing the biometric templates corresponding to different image references with one another and associating together the image references for which the comparison has a similarity score greater than a predetermined threshold; and searching for context information corresponding to at least one of the references of the associated images, and if there is corresponding context information, establishing a link between the associated images.
