METHOD AND SYSTEM FOR EXCHANGING MESSAGES TO GUARANTEE THE ANONYMITY OF A TRANSMITTER

摘要

The invention relates to a device (100) and a method of exchanging SMS/MMS messages between a first terminal (1) identified on a first network (10) by a first identifier (N1) and a second terminal (2) identified on a second network (20) by a second identifier (N2). According to the invention, the non-disclosure of the first identifier (N1) to the second terminal (2) is guaranteed while still allowing said second terminal (2) to respond to the first terminal (1). To accomplish this, the first identifier (N1) of an SMS/MMS message (M1) transmitted by the first terminal (1) to a second terminal (2) is replaced by a reply address (A) associated with at least the first identifier (N1). Because this reply address (A) is accessible from the second network (20), it allows the second terminal (2) to reply to the first terminal (1) without said first terminal (1) disclosing its identifier (N1).
