Network multimedia copyright active following and monitoring system

Abstract

The invention discloses a network multimedia copyright active following and monitoring system. By taking digital fingerprinting and copy detection technology as a core and closely combining with a conventional DRM system, a frame for discovering, following, administrating and monitoring illegal multimedia copies under a network environment is constructed and an active following mechanism, digital fingerprint generation and embedding technology supporting bulk capacity users, copy detection technology and copyright registration and administration technology are realized. The system comprises a characteristic database, a monitoring result database, a network media database, a digital fingerprint database, a copyright registration and management module, a digital copyright management module, a digital fingerprint detection module, a client module, a fingerprint certificate management module, a copyright monitoring module, a copy detection module, a network crawling module and a user query and display interface. Aiming at problems existing in multimedia digital copyright, the invention provides the network multimedia copyright active following and monitoring system, which realizes the copyright active following mechanism and overcomes the shortcoming of the passiveness of a conventional digital fingerprint system.

Description

technical field [0001] The invention belongs to the technical field of computer information security, in particular to a network multimedia copyright active tracking and monitoring system. Background technique [0002] With the rapid development of multimedia technology and computer networks, the storage, reproduction and dissemination of digital multimedia works have become very convenient and fast, which has greatly promoted the online sales and dissemination of digital multimedia works. However, digital multimedia works can be easily copied and redistributed without any quality damage, making the Internet a hotbed for illegal use and dissemination of copyrighted media content. With the rapid development of P2P networks and the widespread use of large-capacity storage media such as DVDs, the problem of piracy will become more serious. Therefore, how to protect the digital copyright of network multimedia and track and monitor illegally disseminated works has become an urge...

Problems solved by technology

Although the digital fingerprint system has been proposed for some time, there are some shortcomings, the most important of which is: the digital fingerprint system is passive and lacks an active search mechanism

However, there are some deficiencies: most systems do not pay enough attention to the resistance to geometric distortion (rotation, scaling, translation, and local clipping, etc.), and are powerless to attack in this area; in addition, there are deficiencies in computational efficiency, and most feature extraction methods have relatively high computational complexity. High, the index structure cannot support efficient feature information retrieval, and it is difficult to meet the online real-time query requirements of the copy detection system

[0010] Through the research and analysis of related fields at home and abroad, it can be seen that: ①Current patents on copy detection are to extract some simple features for copy detection. Although the complexity is low, the identification ability and anti-distortion of the system are relatively weak. , the patents on the index structure supporting efficient retrieval and the robust feature extraction against geometric distortion are still blank; ②Although the patents on digital fingerprints propose some anti-collusion algorithms, which are feasible for small-scale There is a trend of large-scale users. At present, there is no patent for fingerprint encoding with high anti-collusion in the actual large-scale user environment, and there is no patent for fingerprint robust embedding, especially fingerprint embedding against geometric attacks.

③ All fingerprint system patents adopt a conventional passive tracking strategy, that is, the conventional fingerprint system focuses on tracking the co-conspirators from the illegal copies sent for detection, and lacks a mechanism for actively discovering illegal copies
