Problems solved by technology

However, in a large-scale computer network, such as the Internet, there are millions of hosts, and it is a very challenging task to query the watermark in the data distributed in such a network
In this case, it is unimaginable to download pictures only by manual means, and then implement detection

Embodiment

[0034] First of all, it is set that each client has a pair of public and private keys, Public key and Private key, and the private key is safely stored on the hard disk of the device, and any illegal user cannot (or it is difficult) to obtain the private key. It is assumed that the computer environment of the end user is safe, and hackers cannot obtain the decryption key of the protected content and the decrypted content when the decrypted content is executed. The setting program has the ability to resist attacks, and it is difficult for the user to disassemble the executable unit in the system. Finally, for multimedia files (such as 3D models), a secure channel is set between the player and the graphics card, making it impossible for hackers to intercept the decrypted content before the video signal reaches the graphics card.

[0035] With a three-dimensional model, be recorded as 3DModel_A ' as example, illustrate the working process of the present invention:

Abstract

The present invention relates to a digital copyright management system based on digital watermarking and mobile agent, comprising six modules, i.e. a digital media server, a copyright owner, a digital work issuer, a consumer, a bill trade center and a mobile agent center. The present invention aims to realize the copyright protection to digital work lifecycle in open networks. The present invention utilizes the distribution and moving characteristics of mobile agent and directly detect digital watermarks on a detected remote host computer, and what is moved by mobile agent is a watermark detection program but not data, thereby the present invention overcomes the overload disadvantage that the prior server and greatly improves the efficiency of copyright protection and tracing.

Description

technical field [0001] The invention belongs to the field of information security and computer application, in particular to a digital copyright management system based on digital watermark and mobile agent. Background technique [0002] With the development of computer network technology and the popularization of the Internet, the scope of multimedia data distribution is becoming wider and wider, and many information and resources are released in the form of WWW. The premise of realizing more commercial applications on the Internet is to solve the problem of copyright protection. If the problem of copyright protection is not solved, the information and resources released on the WEB pages will be easily used and copied illegally, which will cause manufacturers and authors to be dissatisfied. If you dare to publish information on the WWW, you will only be able to see e-commerce advertisements, some technical reports or other materials that have not been officially published o...
