Abstract
A method for supplying and a method for obtaining, by a terminal, from a first user, a biometric signature of a second user. The terminal receives a radio signal transmitted by a transmitter device according to a near-field communication technology, via a channel using the electromagnetic wave conduction capabilities of the body of the second user when the second user comes into contact with or grazes a surface of the transmitter device and via a channel using the electromagnetic wave capabilities of the body of the first user when the first user comes into contact with or grazes the second user, and obtains, from this radio signal, the biometric signature of the second user. The biometric signature is stored in a secure memory space of the terminal in order to be used subsequently during an authentication of the first user.
