Making system constraints of a specified permission in digital rights management

A computer program product for use in an executing device capable of consuming a content object, which is protected by a digital rights management system and used for making multi-system constraints of a specific permission of a rights object corresponding to the content object, the computer program product including computer executable instructions stored on a non-transitory computer readable medium such that when executed by a processor of the executing device cause it to:

• obtain a rights object related to the content object protected by the digital rights management system, wherein descriptions of a specific permission of the rights object includes system constraint descriptions of a plurality of systems of the same type that apply to a plurality of devices capable of consuming the content object;
• obtain corresponding system information within the executing device according to said system constraint descriptions, wherein the system information includes a type of system within the executing device;
• compare the type of system within the executing device with the system constraint descriptions of the plurality of systems of the same type for determining if a match exists between the type of system within the executing device and one or more of the plurality of systems of the same type;
• and
• based on the aforementioned comparing, determine to permit executing said specific permission for the content object if there is a match between the type of system within the executing device and one or more of the plurality of systems of the same type in said system constraint descriptions, otherwise, determining not to permit executing said specific permission for the content object.
