Method and system for reflecting differences between two files

摘要

A method and system for reflecting differences between two files. The method includes generating a base signature file having a plurality of base bit patterns, each base bit pattern being generated as a function of a portion of data in a first file. A second file containing a plurality of revised bit patterns is generated from a second file. Each revised bit pattern is compared to and matches at least one of the base bit patterns. A delta file reflecting the differences between a first file and the second file based on the base signature file, the delta signature file, and the second file is created.
