FIELD: physics, computer technology.
SUBSTANCE: invention concerns digital rights management system. (DRM) features multiple DRM servers with DRM functionality, and incoming server DRM-I is registered in the system by registration server DRM-R, so that incoming server DRM-I should be a trust server in this system. DRM-I server sends registration request to DRM-R server including representative identification data and public key (PU-E). DRM-R server checks validity of representative identification data, and if the request can be met, DRM-R server generates digital registration certificate by (PU-E) for DRM-I server for registration of DRM-I server in DRM system. Just registered DRM-I server with generated registration certificate can use it for delivery of documents with DRM in DRM system.
EFFECT: possible controlled reproduction or replay of arbitrary digital content forms in medium where documents are shared by a definite group of users.
