Abstract: A method of personalizing a security document, which includes a processing method performed by a processing device in order to prepare personalization of a security document. The method includes obtaining personalization data, encrypting the personalization data by using diversification data associated with the security document so as to produce encrypted data, and transmitting the encrypted data to a personalization device. The encrypted data enables the device to personalize the security document by using the encrypted data and the diversification data. Also described is a method of personalizing a security document by means of such a personalization device, as well as devices that employ the methods.

Abstract: A method of delegating and verifying rights that enables a tutor (10) to delegate rights over a tutee (20) to a third party (30). The method includes creating a delegation attestation (71) that includes a third party authorization (33) comprising the rights over the tutee (21) that are delegated to the third party (31) by the tutor (10). The method further includes storing the delegation attestation (71), and if not already present, storing an affiliation attestation (51) identifying a tutoring relationship between a tutor (10) and a tutee (20) comprising a tutor authorization (13) that includes the rights allocated to the tutor (10) over the tutee (20). There is also an associated verification method.

Abstract: Method of authentication of a user via a terminal including acquisition elements for performing a biometric acquisition, includes: presentation to the acquisition elements by the user of a member to be verified by biometric comparison and triggering by the user a biometric acquisition to obtain an acquisition datum; biometric comparison of the acquisition datum with a prestored reference datum, the user being authenticated if the biometric comparison is positive and not authenticated otherwise, the method further including the following steps: providing the user with elements indicative of a first angle, the user applying a corrective rotation by a second angle so as to match an acquisition datum with the second angle, and in the biometric comparison step the reference datum is matched with the first angle, the biometric comparison being positive if the second angle is substantially equal to the first angle. Device adapted to implement such a method.

Abstract: An affiliation method for identifying a tutoring relationship between a tutor and a tutee. The affiliation method includes the following steps: creating an affiliation attestation that includes a tutor authorization comprising the rights over the tutee that are allocated to the tutor, and storing the affiliation attestation. There is also a related emancipation method, as well as corresponding verification methods.
