Abstract: Authentication and secure wireless data exchange is provided between a chip with an identification code and a dedicated server via a read unit, which carries out contactless read and/or write operations on the chip. The read unit connects to a computer terminal connected to a communication network. A first connection is first established to the communication network from the computer terminal connected to the read unit to the dedicated server using a defined secure data communication protocol. A second connection to the communication network from the read unit to the dedicated server is then established using the computer terminal as a secure data transmission tunnel to directly exchange encrypted data between the read unit and the server invisibly to the computer terminal. Finally, wireless personalized communication is carried out between the read unit and the chip once the chip is identified upon request of the dedicated server.

Abstract: The method allows authentication and secure wireless data exchange between a chip with an identification code (1?) and a dedicated server (35) via a read unit (5). This read unit is arranged for carrying out contactless read and/or write operations on the chip. The read unit is connected to a computer terminal (30) connected to a communication network (300) of computer terminals. For the method, a first connection is first of all established to the communication network from the computer terminal connected to the read unit to the dedicated server using a defined secure data communication protocol. A second connection to the communication network from the read unit to the dedicated server is then established. For this second connection, the computer terminal is used as a secure data transmission tunnel in order to directly exchange encrypted data between the read unit and the server in a manner invisible to the computer terminal.

Abstract: A system, installed in the extension of a line across which an object or a person passes, includes: an optical device for projecting an image of this line onto a photosensitive sensor capable of providing an image signal; at least a processor for processing the image signal; and a screen, connected to the processor, for displaying an image representative of the image signal, called the video image, connected to said processor, wherein the sensor is formed of a pixel matrix. A reticule signal is generated and superposed onto the video image displayed on the screen, the system also being capable of generating electric signals originating from a pixel column which corresponds to the position of the reticule on the screen.
