Problems solved by technology

[0004] At present, the way to prevent digital works from being infringed on the market is mainly to add visible watermarks to the works. These watermarks are basically automatically added for users by the application platform, and the adding position is fixed, usually in the lower left or right corner of the work. This traditional method of adding watermarks There are the following shortcomings: (1) The visible watermark affects the aesthetics of the work on a certain basis; (2) The visible watermark can be erased by cutting or other means, so that the real author cannot prove the ownership of the work; (3) The visible watermark It is very easy to be imitated, which may cause damage to the author’s reputation or other aspects; (4) the encryption method is not complicated enough, and the work is easy to be cracked; (5) even if a watermark is added, it is often difficult for the author to prove himself due to lack of impartiality Copyright

Abstract

The invention discloses a digital copyright protection platform based on a block chain and a national secret SM2 / 3, and belongs to the technical field of digital work copyright protection, the digital copyright protection platform comprises a processing module, an input port of the processing module is connected with an account registration module and an account login module, an output port of the processing module is connected with an account information storage module. An input port and an output port of the processing module are connected with an input account information authentication module, and an input port and an output port of the input account information authentication module are connected with an account information storage module; according to the method, the robust digital watermark is added for the digital work of the user in combination with the human eye visual sensitivity and the image texture self-adaptive algorithm, the visual features of the human eyes can be better met, the appearance of the work has no difference from that of the original work. Meanwhile, the robust digital watermark has invisibility. Therefore, the copyright of the original creator can be protected and the aesthetic property of the work can be maintained by combining the above two facts.

Description

technical field [0001] The invention belongs to the technical field of copyright protection of digital works, and in particular relates to a digital copyright protection platform based on block chain and national secret SM2 / 3. Background technique [0002] The advent of the information age has increased people's demand and utilization of digital works. People widely use digital equipment to produce, process, transmit and store various information, but at the same time it also produces copyright protection of digital works and the security of digital information transmission. Among them, how to prevent digital products (such as images, texts, and data) from being infringed, pirated, leaked, and tampered at will has become a hot topic that needs to be solved urgently. [0003] Because the copying and modification of digital works are very easy, and can be exactly the same as the original works, infringements have been repeatedly prohibited. [0004] At present, the way to pre...
