Abstract: A method and a terminal device for making multi-system constraint of a specified permission in a digital rights. A rights object related to content object is obtained by an executing device. The specific permission descriptions of the rights object include system constraint descriptions of a plurality of systems of the same type. The executing device obtains a corresponding system information in the device according to the system constraint descriptions and compares the system information in the device with the system information in the system constraint descriptions, so as to judge whether there is any system permitted in system constraint descriptions. If yes, it determines to permit executing the specific permission for the content object; otherwise, it determines not to permit executing said specific permission for the content object.
