FIELD: information technology.
SUBSTANCE: invention relates to a method of distributing information content for a mobile device using a digital privilege control (DPC) scheme, and to a mobile device for receiving information content using DPC. The mobile device creates a request file (RORequest.rop) which contains information necessary for creating an privilege object file. The request file is extracted on the computer side and a response file is sent to the mobile device, where the said response file contains encrypted information content (Content.dcf), as well as privilege object file (). The mobile device receives the response file and decrypts and stores the information content. File exchange can take place through a DPC holder made in the mobile device and is accessible to the computer in mass memory mode, or the DPC holder can be made in external memory which is accessed by the mobile device and the computer in turns.
EFFECT: flexible method of distributing protected information content using DPC from a computer system to a mobile device independent of the data transmission protocol or channel type.
