Methods and apparatuses for transferring data between data processing systems which transfer a representation of the data before transferring the data
First Claim
1. A method for transferring data between a first digital processing system and a second digital processing system said method comprising:
- creating a first representation of a first digital media, said first digital media being stored on said first digital processing system;
comparing said first representation to a plurality of representations of a corresponding plurality of digital media;
transmitting said first digital media from said first digital processing system to said second digital processing system if said first representation does not match any of said plurality of representations.

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.
