Abstract

Analysis and identification on software infringement, which is a time-consuming and complicated work, is always done in lab. However, to check whether suspect software infringes upon other’s copyright quickly is the necessity in software infringement cases. An approach of copyright checking based on digital fingerprint is provided in this study, which computes system similarity through segmenting files to be compared, searching boundaries by sliding window and finding the same digital fingerprints of data blocks with simple and complex hash. The approach fits for finding preliminary evidences on the law enforcement spot of software infringement case, thus it has the attributes of efficiency and reliability.
