Abstract
Data on a master is read into a master image file, and the master image file is manipulated to include a benchmark comprising tracking and verification information tied to at least a portion of the master image file. Thus, a copied-to storage media as copied from the master image file also includes such benchmark, a data alteration of the master image file causes a mis-match with regard to the benchmark in such master image file, and a data alteration of the copied-to storage media also causes a mis-match with regard to the benchmark in such storage media as copied from such master image file. The benchmark may include a part identifier and a security identifier.
