Abstract

The invention concerns a method and system for safely transmitting a fax between a transmitter sending the fax and at least a receiver (11) receiving the fax (162) using a fax machine (161) associated with a telephone equipment (16). The faxes (162) are routed between a transmitter and a receiver by a communication network (15) via a fax management center (30). The fax management center (30) provides the receiver (11) with a card, formatted like a credit card, personalized by specific identifiers for each card and each receiver. This card (10) emits brief identifying sound signals, of the DTMF type, at least partially encrypted, varying with each operation, when it is actuated (14) by the receiver (11). The signals received by the microphone (17) of the telephone equipment (16) are transmitted by the communication network (15) to the computer services (18) of the fax management center (30). The transmitted signals and the identification data of the receiver and of the card held (23) by the computer services (18), are electronically processed (24) and compared (25) by the computer service (18) of the fax management center. In the event of coincidence, the fax management center, (30), transmits to the fax machine (161) of the receiver (11), the fax (162) sent to him by the transmitter.
