Patent ID: 8566588

Claim:
A method of wireless authentication and secure data exchange between an identification chip and a dedicated server via a read unit arranged for carrying out contactless read or write, or read and write, operations on the chip, wherein the read unit is connected to a first computer terminal connected to a communication network of second computer terminals, wherein the method includes steps of: (a) establishing a first connection to the communication network from the first computer terminal connected to the read unit towards the dedicated server by using a defined secured data communication protocol; (b) establishing a second connection to the communication network from the read unit to the dedicated server using the first computer terminal as a secure data transmission tunnel in order to directly exchange encrypted data between the read unit and the server in a manner that is invisible to the first computer terminal; (c) establishing wireless personalised communication between the read unit and the identification code chip for an encrypted data transfer; and (d) directly exchanging encrypted data between the read unit and the server in a manner invisible to the first computer terminal by using the secure data transmission tunnel to exchange the encrypted data.
