A method and a device for authenticating a user. A signal representative of at least one character traced by the user on a surface of a transmitter device is received by the authentication device. The transmitter device includes an antenna able to transmit a radio signal to a terminal of the user via a channel using the electromagnetic wave conduction capabilities of the body of the user when the hand of the user traces the at least one character on or close to the surface of the transmitter device. The authentication device checks whether the received signal corresponds to a previously stored control signal and, in the event of a positive check, confirms authentication of the user.

Method and device for authenticating a user

A method for recognizing a user carrying a terminal capable of receiving a radio signal coming from a device equipped with an antenna suitable for transmitting the signal. The signal is intended to be transmitted between the device and the terminal by using electromagnetic wave conduction capacities of the body of the user when at least one part of his/her body is in the vicinity of the antenna. When the user makes a characteristic movement, to move the part of his/her body close to the antenna, the device transmits a characteristic signal of the movement. The method includes: receiving a signal coming from the device; generating a characteristic datum of the movement; obtaining at least one signature; comparing the characteristic datum with the signature; and depending on the results of the comparison, recognizing the user.
