Abstract: A system allows the display of a private file on a screen of a telecommunications terminal. This system includes a first and a second Internet site. In the first Internet site, a first image contains a coded link to an address of a file of the second Internet site. The private file is stored in encrypted form in the meta data of the file in the second Internet site. A program recognizes the coded link and searches the meta data of the file whose Internet address corresponds to the coded link for authorization of a person connected to the first Internet site to view the private file. The program downloads the private file of the second Internet site via a remote protocol from the telecommunications terminal if viewing is authorized, to display the private file on the screen.

Abstract: The procedure concerns set-up of an anonymous telephone call between two persons, A and B, each equipped with a GSM terminal incorporating a proactive SIM card, and a specific anonymous call application according to the following protocol: party A application ACC_A enables caller A to select the nickname of B (11) and display information describing B (21). The application of party A sends (31) a call request and information describing A to party B application ACC_B via an SMS type message. The application of B displays (42) the information received from A to enable B to accept or refuse the call (52). Application ACC_B sends (62) the reply of B to ACC_A by an SMS message. If the call is accepted, the application of A sets up (81) the telephone call.
