Digital image ownership protection cloud platform based on confidential calculation

Abstract

The invention discloses a digital image ownership protection cloud platform based on confidential calculation, which is based on a secGear framework, adopts an autonomously designed authentication protocol, and comprises a front end and a rear end, the front end realizes user login, user registration, image watermark addition and image watermark extraction; and the rear end uses a python language, compiles through a Flask framework, and provides a verification interface for user login, user registration, image watermark addition and image watermark service of the front end. Wherein only user login, encryption and decryption of registration information and calculation of watermark image key parameters are executed in a secGear framework, and other operations are all realized in front-end and rear-end open execution environments. The method has the advantages of being high in safety, good in practicability and capable of resisting most algorithm attacks and protocol attacks. Compared with an evidence storage link of an existing digital copyright service platform, the method has the advantages that the source file is directly subjected to copyright information steganography, a basis is provided for infringement judgment and evidence collection, and the problem of infringement judgment dispute is reduced.

Description

technical field [0001] The invention relates to the field of confidential computing, in particular to a digital image ownership protection cloud platform based on confidential computing. Background technique [0002] The development of science and technology makes the dissemination of information very easy. The dissemination of digital images can be seen everywhere on the Internet. In addition, it is almost costless to copy images, so digital images are easy to be pirated and infringed. The phenomenon of embezzling digital pictures has been repeatedly banned, and the losses to image creators are immeasurable. However, due to the high difficulty of identifying whether images have been stolen, the long time for legal proceedings, and the high costs, the infringed will most likely choose to remain silent in the face of these difficulties. Therefore, the problem of digital image theft is becoming more and more serious. Therefore, research on image digital copyright protection t...

Problems solved by technology

However, the current research on digital watermark encryption technology is mostly limited to the algorithm research of anti-geometric attack, and there is no systematic protection strategy for malicious attacks in the process of image data transmission and encryption.

In addition, the current digital copyright management control mechanism relying on third-party organizations is cumbersome, costly, inefficient, and insufficient evidence for rights protection cannot meet the needs of digital image ownership protection
