Methods and apparatus for attacking a screening algorithm

摘要

Methods and apparatus for attacking a screening algorithm. The methods include the steps of searching a medium to determine a location of at least one sample stored on the medium, and applying the sample to content, wherein the content would not pass the screening algorithm but for the application of the sample. Once the locations of the samples are known, the attacker can use the samples to distribute a compressed version of the disk or a song contained on the disk from which the samples are derived, use the samples to import any disk into the SDMI domain, or use the samples to smuggle pirated music into the SDMI domain.
