The invention relates to a method 20 for proving at least one piece of user information. According to the invention, the method comprises the following steps. A requester device 12 sends to a server 18 a first message 22 including a request for proving at least one piece of user 11 information and data identifying a requester. The server generates 24 requester authentication data and associated data identifying a transaction. The server generates 26 a proof of user information using the at least one piece of user information and the requester authentication data. The server sends to the requester device a second message 28 including, as a request response, the proof of user information and the associated data identifying the transaction. A verifier device 12 sends to the server a third message 214 including a request for getting authentication data associated with data identifying a transaction and the associated data identifying the transaction. The server sends to the verifier device a fourth message 218 including, as a request response, authentication data associated with the data identifying the transaction. The verifier device or a verifier 19 authenticates the at least one piece of user information only if the received authentication data matches the requester authentication data. The invention also relates to corresponding requester device, verifier device and server. |
