<p>The invention concerns a device for identifying and locating a person in real time, comprising at least a fixed station (1) generating a final random code, an operation and control centre (2), a terminal (3) arranged in the proximity of the station (1), and connecting means (4) between the operation and control centre (2) and the terminal (3). The transmission to the operation and control centre (2) of the final random code through the terminal (3) is carried out by means of a signal transmitted by the station (1). The final code results from applying algorithms at least to the station (1) code, a random code generated by the station (1), a control key particularly taking into account a random code previously used by the station (1) and the code particular to the station (1). The algorithms are known to the operation and control centre (2).</p> |
