Abstract: A method for receiving a signal during an intra-body communication via a user carrying a terminal. The method includes, at the level of the terminal: receiving, from a communication device, a signal characterizing the fact that an approach gesture performed by the user toward the device has been performed between two times; detecting the time interval, between the two times, in which the amplitude of the signal is at a maximum; detecting, in the time interval, information determining whether or not the user has touched the device between the two times; and validating a transaction depending on the value of said detected information.

Abstract: 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.
