Abstract (en)

[origin: WO2011041916A1] Embodiments provide a method that causes a plurality of virtual machine instructions to be interpreted for indications of a mobile device's hardware identification information, thus forming a plurality of hardware instruction interpretations. The embodiment also combines each of the plurality of hardware instruction interpretations and hashes the combination to form a quasi-hardware device identifier. An encryption process is based on the quasi-hardware encryption device identifier and the media is then encrypted using the encryption process. The encrypted media is transferred to the mobile device wherein the mobile device decrypts the media based at least in part on the mobile device's internal knowledge of the quasi-hardware device identification.
