Abstract: A system, apparatus, and method are directed to evolving detectors in an Artificial Immune System for use in detecting unauthorized computing activities. In one embodiment, a population of detectors is generated with a matching value and expectation value of zero. The detectors are then compared to logged fragments of system calls within a computing device to modify the matching value. When the matching value for a given detector is equal to or greater than an expectation value, the detector's expectation value may be set to the matching value. The detectors may then evolve and/or generate other detectors using mutation, and/or recombination, or the like. Detectors continue to generate and/or to evolve until a detector's matching value reaches a determined value, in which case, the detector may be evaluated to determine if an unauthorized activity is detected. If an unauthorized activity is detected, a detection response may be performed.

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.
