    摘要： In embodiments, the present invention provides method and system for determining if an existing pass log may be reused. The method may include associating an existing pass log with an encoding profile. The method may further include computing with a processor a signature for the encoding profile and for a target encoding profile. The method may include comparing with the processor at least a portion of the two signatures and based on a result of the comparing, storing in a processor accessible memory at least one of an indication that the pass log file may be used in conjunction with the target encoding profile and an indication that the pass log file cannot be used in conjunction with the target encoding profile.

    摘要： 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.
