Abstract: A method and apparatus for enabling hardware platform identification while ensuring privacy protection. The apparatus comprises a computer-readable medium that stores computer-executable instructions. Those instructions, when executed by a microprocessor, cause an expected hash value, which is derived from a key and a first identifier for a computer system; to be compared with a hash value, which is derived from the key and a second identifier for a computer system. A microprocessor for executing those instructions may comprise an identifier that identifies the microprocessor, and embedded instructions for comparing a hash value, derived from the identifier and a key, to an expected hash value.

Abstract: A system and method for controlling access to an object. The system stores an object and a processor identifier. The system includes a verification agent that can access information embedded in a processor and then calculate from that embedded information a value that may be compared with the stored processor identifier. A comparison agent is used to compare that value with the processor identifier to determine whether the processor corresponds to the processor identifier. If the value that the verification agent returns matches the processor identifier, then the computer grants the user access to the object.
