Method and System for Monitoring and Tracing Multimedia Resource Transmission
First Claim
1. A method for monitoring and tracing transmission of multimedia resources, comprising:
- capturing data packets in a network link, reassembling the captured data packets to complete restoration of data streams, and storing the restored data streams into a data stream database; and
extracting data fragments from a multimedia file as file DNA fragments to construct a file DNA, and storing the file DNA into a file DNA database; and
invoking the file DNA from the file DNA database, and identifying the file DNA fragments of the file DNA in the data streams to obtain identification results.
