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.

The invention relates to a method for granting access to a service provided by a connected device for a user having a user's device and requesting said access, the method comprising the steps of: receiving by the user's device from the connected device a request to validate a user profile, a user profile corresponding to a list of at least one data item representing the user's capabilities to use a service provided by the given connected device; requesting by the user's device to a verification server associated to the at least one data item to validate said data item, and receiving a digital signature of said data item generated by the verification server as a proof of the validation; transmitting the data item of the user profile and its digital signature to a device belonging to the owner of the connected device for it to be informed that said data item is validated, the user profile being considered as validated when the digital signatures of all the data items listed in the user profile are correctly verified by the owner's device; granting for the user access to the service provided by the connected device when the user profile is validated.

The invention relates to a method for managing the reputation level of a first communication device (), said reputation level () being stored into a first secure enclave () embedded in said first communication device (). The method comprises the steps of: receiving from the first communication device () by a second communication device () an information message; verifying that the information message is consistent with data obtained from a sensor embedded in the second communication device (); generating a feedback message by the second communication device () to be transmitted to the first communication device () indicating if the information message is consistent for the secure enclave () of the first communication device () to update its reputation level.
