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: Disclosed is a method implemented in an identity document including a microcircuit and a unit enabling the microcircuit to communicate with a terminal, the microcircuit being designed to permit the transmission of data obtained (directly or indirectly) from data memorized in a storage zone in response to a request received from the terminal, furthermore including the following steps: reception by the microcircuit of an identifier of the terminal; at least partial comparison of the identifier of the terminal and of at least one portion of an identifier stored in the microcircuit; and performance of a set action depending on the result of the comparison. An identity document in which such a method is implemented is also described.

Abstract: The invention relates to systems and methods of securely transmitting an image stored in the memory of an identity document to a first terminal that is suitable for receiving the image. In various implementations, operations are performed by the identity document, including the identity document receiving an attribute transmitted by the first terminal; generating a marker from the attribute received from the terminal; including the marker in the image; and transmitting the image containing the marker, which may be referred to as the “modified” image, to the terminal.

Abstract: Methods and devices for enabling authentication may include a first stage in which a first electronic device of the first entity communicates with a second electronic device of the second entity via a telecommunications network. During the first stage, the first electronic device generates a first token and transmits it from the first electronic device to the second electronic device via the network; and the second electronic device generates a third token and transmits the third token to the first electronic device via the network. During a second stage, authenticating a first non-authenticated entity as being the second entity as a function of a second token contained in a first portable electronic device of the first non-authenticated entity occurs; and authenticating a non-authenticated entity as being the first entity as a function of a fourth token contained in a second portable electronic device of the second non-authenticated entity also occurs.

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: 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.

Abstract: A method and system for controlling the execution of a function protected by authentication of a user and which is provided for example for the access to a resource. The method includes inputting, by the user, of personal data using an input device, authenticating the user with the input personal data for authorizing or not authorizing the execution of the function; in a secure card connected to the input device, storing limited validity authentication data dependant on the input data; when the card is connected to a processing device by which the user generates a message whose processing implements the function, using the stored data, taking into account the limited validity, to authorize or not authorize the execution of that function.
