METHOD AND SYSTEM FOR MAKING EDRM-PROTECTED DATA OBJECTS AVAILABLE |
摘要 |
A method and a system make EDRM-protected data objects available to users. Access rights to an EDRM-protected data object are produced depending on partial access rights to at least one or more data objects, which data objects are contained in the respective EDRM-protected data object. The access rights to the EDRM-protected data object are calculated by a client computer of the user using an access right differentiation function depending on the partial access rights which are made available by different EDRM servers. A data object key of the EDRM-protected data object is calculated by the client computer of the user using a key differentiation function depending on partial keys which are made available by the different EDRM servers.
