PROCESSING OF DATA ASSOCIATED WITH A DIGITAL SERVICE

摘要

The invention relates to the processing of data associated with a digital service. In order to process a digital datum (DAT) created, stored, used or intended to be used by an application (AP) dedicated to a digital service and executed in a terminal, a protection system (SP) intercepts a memory access request (RA) sent by the application to the operating system of the terminal and containing the digital datum. A memory manager (GM) identifies the application that sent the request. A parameter server (SVP) determines at least one context parameter (CPR) relating to the application in order to associate same with said request. A service controller (CS) identifies the service according to the parameter associated with the request. A key generator (GC) generates a key (KPD) according to the processing parameters associated with the service identified in order to process (e.g. encrypt or decrypt) the digital datum as a function of the key generated.
