#CMT# #/CMT# The method involves identifying an application (AP) at the origin of a memory access request (RA) using a memory manager (GM), after interception of the request for an operating system, where the request includes digital data (DAT). An identifier of a data network (RD) associated to the identified application is determined using a parameter server (SVP). A data protection key (KPD) e.g. encryption key, is generated according to the identifier of the determined network using a key generator (GC). The digital data is processed according to the generated key using an encryption module (MC). #CMT# : #/CMT# Independent claims are also included for the following: (1) a system for processing a digital data, comprising a determining unit (2) a computer program comprising a set of instructions to perform a method for processing a digital data (3) a recording medium comprising a set of instructions to perform a method for processing a digital data. #CMT#USE : #/CMT# Method for processing digital data created, stored or utilized by an application of a data network e.g. telecommunication network, banking service network or removable memory card e.g. smart card, and executed in a computer terminal e.g. personal computer, mobile radio terminal, banking terminal, application server or surveillance camera, using a system (claimed) i.e. protection system. #CMT#ADVANTAGE : #/CMT# The method ensures the absence of data exchange between two distinct data networks via a memory medium, conserves time and money for a user of a computer terminal and optimizes downloading of the data in the terminal by facilitating management of resumption on an incident such as extinction of the terminal. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic block diagram of a protection system for processing a digital data relative to a data network. AP : Application DAT : Digital data GC : Key generator GM : Memory manager KPD : Data protection key MC : Encryption module RA : Memory access request RD : Data network SP : Protection system SVP : Parameter server. |
