A software method of setting a state in a processor regarding whether a processor number encoded in the processor will be available for reading is described. The method comprises prompting the user to enter an indication whether the processor number should be available for reading by a program. Then, setting a state to inhibit the processor number from being read by a program if the indication indicates that the processor number should not be available for reading by the program. For one embodiment, the method further includes testing the indication if a request for the processor number is received, and releasing the processor number if the indication indicates that the processor number is available.

Processor unique processor number feature with a user controllable disable capability

A system featuring an interface unit connected to a programmable unit is described. The interface unit is capable of containing a time-sensitive key. The programmable unit is allowed to receive digital content from the interface unit upon establishing that the time-sensitive key is also contained therein.

Conditional access and content security method

A method for encoding MPEG compatible video data for subsequent compression comprises detecting a plurality of frames of video data organized as a GOP, generating an encryption key for the GOP, and encrypting the video data using GOP-synchronized substitution, transposition, and rotation transformations that are parameterized by offsets derived from the generated encryption key.
