Abstract
Facility for transferring data over a network between two network endpoints by transferring hash signatures over the network instead the actual data. The hash signatures are pre-generated from local static data and stored in a hash database before any data is transferred between source and destination. The hash signatures are created on both sides of a network at the point where data is local, and the hash database consists of hash signatures of blocks of data that are stored locally. The hash signatures are created using different traversal patterns across local data so that the hash database can represent a larger dataset then the actual physical storage of the local data. If no local data is present, then arbitrary data is generated and then remains static.
