HASH DATA STRUCTURE FOR FILE COMPARISON AND HASH COMPARISON SYSTEM AND METHOD USING THE SAME

摘要

The present invention relates to a hash technology related to data files. A hash data comparison system according to an embodiment compares source files with each other using hash data including file information and a hash value. The hash data comparison system includes a file information generation unit, a hash generation unit, and a control unit. The file information generation unit checks an attribute of each source file and generates file information about the source file. The hash generation unit calculates a hash value by applying a hash function algorithm to at least part of the source file. The control unit generates hash data for the corresponding source file including the file information and the hash value.
