Abstract:
1. A method for detecting copyright violation, said method comprising: receiving a selectable data stream of suspected copyright infringing material; using a linear shift generator to generate a first electronic signature for said data stream of said suspected copyright infringing material; using a linear shift generator to generate a second electronic signature for an original copyright material; comparing said first electronic signature with said second electronic signature, wherein a match of said first electronic signature with said second electronic signature indicates a likelihood that said suspected copyright infringing material and said original copyright material are the same; parsing said data stream of suspected copyright infringing material into suspected copyright infringing material data segments; generating a suspected copyright infringing material data segment electronic signature for each said suspected copyright infringing material data segment; parsing said original copyright material into original copyright material data segments; generating an original copyright material data segment electronic signature for each said original copyright material data segment; determining that at least one of said suspected copyright infringing material data segment electronic signatures matches at least one of said original copyright material data segment electronic signatures; and visually examining said suspected copyright infringing material data segment having said suspected copyright infringing material data segment electronic signature matching said original copyright material data segment electronic signature.
