Embodiment Construction

[0028] Embodiments of the present invention will now be described with reference to the drawings, in which like reference numerals represent like elements.

[0029] Such as figure 1 with figure 2 As shown, the digital copyright protection method based on virus detection and watermark embedding in this embodiment includes the following steps:

[0030] Step S1, the identity authentication module accepts the owner to log in, and when the information submitted by the owner is consistent with the owner user information in the database, it is judged whether the owner's digital certificate is valid;

[0031] Step S2, when the owner's digital certificate is valid, the digital media publishing module receives and stores the media work file uploaded by the owner;

[0032] Step S3, the digital media release module detects whether the uploaded media work file contains viruses or suspicious codes, if yes, proceed to the next step, if not, go to step S5;

[0033] Step S4, delete the med...

Abstract

The invention discloses a digital right protection method based on virus detection and watermark embedding, comprising the following steps of carrying out virus detection on an uploaded media works file; embedding an owner user information watermark and a platform mark watermark into the media works file; generating a license after a consumer pays the purchase cost; embedding consumer user information and PC information into the media works file in a mode of the watermark; carrying out binary transformation on the media works file with the owner user information watermark, the platform mark watermark and the consumer user information-PC information watermark; encapsulating the license and the media works file after transformation to download; when a digital certificate of the consumer is valid or a only physic mark of a current PC is correct, carrying out decapsulation and format transformation on the downloaded media works file according to the use jurisdiction stipulated by the license of the downloaded media works to play. The method can avoid virus entry and off-line diffusion and can realize diffusion channel tracing.

Description

technical field [0001] The invention relates to digital watermarking technology, multimedia technology and information security technology, in particular to network multimedia data copyright protection technology. Specifically, the present invention relates to a digital copyright protection method based on virus detection and watermark embedding. Background technique [0002] In a complex network environment, providing safe and reliable copyright protection for network multimedia data has gradually become the focus of the digital media industry, and the resulting digital rights management (Digital Rights Management, hereinafter referred to as DRM) technology can realize copyright protection , which combines the access mechanism of hardware and software to effectively control the access of network multimedia data in its life cycle. Since its birth, many scholars at home and abroad have conducted in-depth and extensive research on the architecture and key algorithms of DRM. ...
