Method for controlling by a server the use of at least one data element of a data owner

Abstract

The invention relates to a method for controlling by a server called secure server the use of a first set of at least one data element of a data owner and provided by a communication device, the method comprising the steps of: receiving at least one digital signature representative of a process authorized by the data owner and adapted to carry out a series of at least one instructions using the first set of at least one data element; receiving from a process entity the series of at least one instruction, and a ciphered version of the first set of at least one data element which is communicated to the process entity by the communication device; verifying that the series of at least one instruction correspond to a process authorized by the data owner of the communication device by comparing the at least one digital signature received by the secure server with a digital signature obtained by the secure server using as an input the series of at least one instruction received by the secure server; and if the series of at least one instruction correspond to an authorized process: deciphering the first set of at least one data element; generating a result data by executing the series of at least one instruction using the first set of at least one data element as an input; transmitting the result data to the process entity.
