A method, apparatus, and manufacture for debugging and crash logging is provided. A log file is received, where the log file includes encrypted log messages that indicate execution trace of obfuscated code while leaving code locations of corresponding code in the obfuscated code unknown. The encrypted log messages include execution way-point indices. Next, at least a portion of the log file is then decrypted. A debug log viewer is then employed to view the decrypted log file. The debug log viewer includes an execution way-point manifest that correlates each of the execution way-point indices to a corresponding code location.

Method, manufacture, and apparatus for secure debug and crash logging of obfuscated libraries

Various embodiments are directed towards employing a container and communication protocol proxy component within a client device to receive securely real-time streamed, progressively downloaded, or adaptively streamed container over a network using one container and communication protocol, and to securely decrypt the container and provide it to a media player using a different container and communications protocol. In one embodiment, the container is in Flash Video (FLV) file format. A browser or the media player on the client device may be used to request the container. The requested container is sent over one communication protocol and intercepted by the container and communication protocol proxy component. The container may be received as selectively encrypted container. The container and communication protocol proxy component then may enable decryption of the container and providing of it to the media player using another container and communication protocol combination.

Progressive download or streaming of digital media securely through a localized container and communication protocol proxy

A method, apparatus, and system are directed towards employing a chain of permission keys obtained during playing of advertisements within content to enable continued playing of the content. A sequence of encoded permission keys are generated with each encoded permission key, except a last permission key, incorporating a scrambling key useable to decode a next encoded permission key within the sequence of encoded permission keys that enables playing of a next portion of the content. If playing of any advertisement within the content is avoided, then access to an associated scrambling key useable to decode a next permission key is prevented, which in turn inhibits playing of a next portion of the content. In another embodiment, a heartbeat analysis may also be performed to monitor if skipping of an advertisement is being attempted, and if so, playing of the content is prevented.

Preventing unauthorized modification or skipping of viewing of advertisements within content

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.

Tamper prevention and detection for video provided over a network to a client

A system, apparatus, and method are directed towards managing entitlement/right revocation and delivery to be performed within a non-addressable media network. Such networks may include for example a client device behind a network address translation (NAT) device, employs non-addressable satellite components, or so forth. A server notifies clients that entitlements, revocations, or the like are available by sending a request for communications with the client. The client initiates a connection to receive the entitlements, or the like, and then disconnects from the server. If the client fails to initiate a connection, the server may continue to send a request for a connection, or even change encryption keys to the content to prevent access by the client. In one embodiment, failure to receive an acknowledgement response from the server of a connection with the client, or from the client, may result in invocation of a revocation failure action.
