Classification: CPC H  G | IPC H

Claim 21:
22. A method for transmitting data from a sensing device, the method comprising steps of:
permanently store an unique code in a storage medium of the sensing device;
generating, on the sensing device, a private key and a public key in response of providing a provisioning code matching the unique code, preferably provided by a provisioning device;
signing, on the sensing device, collected data provided by a sensing unit and a timestamp provided by a time-keeping unit by said private key so as to provide a digital signature;
transmitting to a server a packed data comprising the collected data, the timestamp, the digital signature and the public key; and then
permanently erase, on the sensing device, the private key, in response of a detection of a tampering of the protecting casing of the sensing device and/or of a detection of a remaining energy of a storage module of the sensing device being below a given energy threshold and/or of a reception of an end-of-live signal.
