METHOD AND COMMUNICATION SYSTEM FOR THE COMPUTER-AIDED DETECTION AND IDENTIFICATION OF COPYRIGHTED CONTENTS

摘要

Disclosed is a method for the computer-aided detection and identification of copyrighted contents that are exchanged between at least two computers in a communication network, especially in peer-to-peer networks. Said method comprises the following steps: - first data packets that are specified according to an execute command and are analyzed regarding at least one first criterion are fed to a first computer (PAT), first and second parameters being determined from the data packets meeting the at least one first criterion; - the first computer (PAT) determines the first data packets encompassing the second parameter from all first data packets that are fed to the first computer (PAT) and transmits said data packets to a second computer (FP); - a third computer (CRAW) sends at least one inquiry message for detecting data with copyrighted contents to the communication network, said third computer (CRAW) receives reply messages in reaction to the at least one inquiry message and requests second data packets meeting at least one second criterion from the communication network and analyzes the same, third and fourth parameters being determined from the data packets meeting the at least one second criterion; - the third computer (CRAW) determines the second data packets encompassing the fourth parameter from all second data packets that are fed to the third computer (CRAW) and transmits said data packets to the second computer (FP); - the first computer (PAT) transmits the first parameters to the third computer (CRAW) in order for said first parameters to be used in the second criteria; and - the third computer (CRAW) transmits the third parameters to the second computer (PAT) in order for said third parameters to be used in the first criteria.
