The system comprises a server (1), two clients (2,3), and a symmetric key of the former client using data to be detected. An asymmetric key pair is obtained for registration by server, to encode the private key with the asymmetric key of former client. The asymmetric key pair consists of a private key and an official key. The encoded private key is communicated to the server and to release the official key so that the server receives latter client, for preserving the data. The server is arranged to store the encoded data and the encoded private key of former client. Independent claims are included for the following: (1) a method for safe server based storage and release of data; and (2) a computer program. |
