Digital copyright protection platform based on block chain and national secret SM2/3

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.

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.
