Abstract
Method for anonymously transmitting a message by means of a telecommunication network. A first exchange () between the sender () and the receiver () of said message replaces identifying features (MSISDN) of the sender () of the message by a first alias identification (CID). The conversion between the said identifying features (MSISNDN) and the first alias identification (CID) is permanent, or at least secure for several weeks. The first alias identification (CID) is replaced by a second alias identification (CMID) at the receiver () or in a further exchange (). The second alias identification (CMID) enables the receiver to identify the transmitter.
