摘要： This invention relates to a method to compensate by a server a clock deviation of a card i by maintaining a time base T base ( i ) synchronized with card i, the method comprising the steps of: receiving (300) at a time TS a dynamic card verification dCVV code value generated by card i; providing (301) a set of at least two dCVV code corresponding to two successive dCVV time periods; if (302) the dCVV code received from card i corresponds to one of the dCVV codes of the provided set but is different from the reference dCVV code, determine (303, 304, 305) the minimum possible timing drift Min_td between the time base maintained by the server for the card and the time base Tbase ( i ) of the card; updating (306) time base Tbase ( i ) by addition of a time drift correction equal to the minimum possible time drift Min_td.

摘要： The invention relates to a method for the radiofrequency communication of data, in which the receiving of and/or access to said data is controlled by control means, including an electronic microcircuit, on the basis of access rights. The method is characterized in that the transmitted data includes time information (IT), and in that the access rights (Da) are controlled on the basis of said time information. The invention also relates to a device for controlling access rights as well as to a radiofrequency receiving device including same.

摘要： This invention relates to a method for provisioning a wireless control device (115) with an information element allowing to identify visually at least one unauthorized user in a restricted area, the restricted area comprising a gateless control area being equipped with at least an image sensor (112) and an electronic reader (113) supporting a short range radio technology allowing to read data memorized into a wearable device (111) carried by a user (110). The method comprises the steps of: providing (120, 121) by the image sensor a digital image of at least one user that is detected as passing through the gateless control area; extracting from the provided digital image of the detected user a first face detection dataset; providing (122, 123) by the electronic reader a second face detection dataset memorized in a wearable device carried by said detected user; applying (130) facial recognition over the first and second face detection datasets in order to determine if the user associated to the first face detection dataset is the same as the one associated to the second face detection dataset, the detected user being identified as authorized in that case and identified as unauthorized otherwise; sending (126) to a wireless control device a message comprising an information item adapted to ease the visual identification of an unauthorized user.

摘要： The invention relates to a method 20 for accessing a private key.
The method comprises:
- storing, by a first device 12, the private key and an associated public key;
- generating 22 an access token;
- sending 24 to a second device 14, the access token;
- sending 28, to a first server 16, an address relating to a decentralized identifier and the access token;
- sending 29, by the first server, to a ledger 112, a request for getting a decentralized identifier along with the decentralized identifier address;
- sending 212, to the first server, the decentralized identifier including the public key;
- generating 214 a challenge;
- encrypting 216 the challenge;
- sending 218, through a second server 18, to the first device, the encrypted challenge and the access token, an address relating to the second server being identified by using the decentralized identifier;
- verifying 224 whether the received access token is or is not the generated access token;
- decrypting 226, only in the affirmative, by using the private key, the encrypted challenge;
- sending 228, to the first server, the challenge;
- verifying 230, whether the received challenge is or is not the generated challenge; and
- attesting 232, only in the affirmative, that the decentralized identifier includes data that belongs to a user.
The invention also relates to corresponding first device, first and second server and system.
