Abstract
A system, apparatus, and method are directed to providing digital copy protection of media using a subscriber/publisher architecture. In one embodiment, a publisher employs various dynamic and/or static tamper detection, including, filter graph change detectors, ICE detectors, screen scraping detectors, debugger detectors, pattern recognizers, or the like. When a tampering event is detected by one or more of the publishers, the tamper event may be published for access by a subscriber. Published tamper events may be pushed to or pulled by the subscribers. When one or more subscribers receive the tamper event, the subscriber(s) may perform one or more tamper response actions according to various business rules, and/or other core rules.
