Abstract
Described is a system and method for providing protection of media by the detection of unauthorized client behaviors and the communication of the unauthorized client behaviors to augment the invention's detection abilities. A variety of detectors are sent to a client process and the responses are evaluated to detect the presence of an unauthorized software behavior on the client. Unauthorized behaviors include alteration of a client process as well as simultaneously running processes that might enable unauthorized copying of protected media. Communication of unauthorized software behaviors includes sharing of memory detectors among servers on a network, and the sending of memory detectors to other clients to detect previously unseen unauthorized behaviors on the other clients.
