摘要： A method for authenticating at least one document having a predetermined format and carrying at least one security pattern of appearance that varies as a function of an angle of observation, the method comprising the steps of: capturing at least one image of the document; determining a camera angle by comparing geometric characteristics detected in the document and stored predetermined geometric characteristics; deducing an expected appearance for the security pattern; comparing the expected appearance with an appearance detected in the image of the document; and declaring the document authentic when the expected appearance matches the detected appearance.

摘要： The invention proposes a method for controls on persons in possession of a document comprising a machine-readable zone containing a document number and an electronic chip in which an authentication biometric is stored, comprising: at a first step (100), acquiring (120) a biometric datum, acquiring (110) the document number by reading the machine-readable zone, and recording (130), in a memory (20), the number linked with the biometric datum, and at a second step (200), acquiring (210) a biometric, from said biometric datum retrieving (220), in the memory, the number of the identity document corresponding to the person, accessing the content of the chip and retrieving the authentication biometric datum (240), and performing authentication (250) of the person by comparing the authentication biometric datum with a biometric datum of the person.
