Data processing device e.g. mobile telephone, safeguarding method, involves communicating private system with device under interconnection of public systems, and providing communication between public system and device using application

摘要

The method involves using system-specific non-standard software, which is derived from standard software by a private system (2). The private system communicates with an external data processing device under interconnection of the public systems (1). The device is networked with a computer (3). The communication between the public system and the external data processing device occurs using a standard application. Independent claims are also included for the following: (1) an arrangement for safeguarding the data processing systems (2) a computer program for safeguarding a data processing device (3) a computer readable storage medium storing a program for safeguarding a data processing device.
