Processing of cellular radio data, in particular by a SIM card of a terminal in a mobility situation, said SIM card receiving a current cell identifier and comparing the current identifier with an identifier previously stored in memory, in order to generate a notification intended for a remote server when there is a difference between the current identifier and an identifier previously stored in memory. More particularly, the SIM card stores in memory a list of current identifiers of respective cells in which the terminal is successively located, and the sending of a notification to the server occurs only if the current identifier is absent from this list.

Processing of cellular radio data implemented by a SIM card, particularly for security purposes

A system for managing at least one service access authentication data item, including a device for accessing at least one service. The system also includes a mobile terminal including a mechanism managing the authentication data item and an identifier of the service, a communication interface between the access device and the management mechanism, and a software interface configured to determine the service identifier and to utilize the management mechanism, via the communication interface, on access to the service. The system for example is applicable to website access authentication services.
