Abstract
A method for transferring data between processing systems and systems for transferring data. A method in one example creates a first representation of a first digital media which is stored on a first digital processing system. The first representation is compared to a plurality of representations of a corresponding plurality of digital media. Typically, but not necessarily, the plurality of representations are stored on a second digital processing system and the first representation is transmitted to the second digital processing system. The first digital media is transmitted to the second digital processing system if the first representation does not match any of the plurality of representations.
