One embodiment includes method for determining whether a player application is authorized to play protected content. The method comprises reading a digital signature associated with the player application from a predetermined memory location using a protection interface associated with the player application, where the digital signature comprises one or more file designations. The embodiment further comprises mapping, by the protection interface, the one or more file designations to one or more files associated with the player application and transmitting mapping information from the protection interface to a verification application stored on a storage medium. The verification application is configured to determine whether the player application is authorized to play the protected content if the one or more file designations match the one or more files based on the mapping information.

Systems and methods for detecting authorized players

Systems and methods for performing secure playback of media content are described. One embodiment, among others, is a method for performing secure playback of video in a hardware protection module. The method comprises receiving media content from a media player comprising video data, audio data, and navigation data. The method further comprises receiving digital rights management (DRM) information relating to the media content, removing a portion of the video data from the media content, forwarding the audio data, navigation data, and a remaining portion of the video data to the media player for decoding, and decoding, in the hardware protection module, the portion of the video data.

Systems and methods for performing secure playback of media content

A system and method is disclosed for enforcing a third-party factory test during a quality verification of a newly-manufactured computing device. During an assembly line quality verification, a factory implemented test and a required third-party factory test are executed on a computing device, and then the execution verified by an external process. On verifying the required third-party factory test was executed, the computing device is configured to execute a release image on a subsequent startup of the computing device.
