Improved method for transmitting data and related service data

摘要

A method of transmitting data and service information associated with said data, including an addressing step during which a set of service information D(Si) that is intended to be stored is referenced by means of an address AD. The address AD includes a session identifier Si, a session being defined as a string of successive activations of different communications means. Service information D(Si) is marked unequivocally by means of an identifier Si that is invariant throughout the session concerned. Thus no element external to that session can reach or degrade the service information, and its permanence is guaranteed until the end of the session.
