With the development of science and technology, the spread of images on the Internet is getting faster and faster, which also reduces the cost of infringement and brings immeasurable losses to image creators. In order to solve the problem of digital image infringement, this paper uses encryption algorithm and signature algorithm to design a verifiable message delivery scheme based on timestamp, and applies it to the copyright protection of digital image, designs and implements a copyright protection system based on digital signature and timestamp. Our system provides a new reference solution for the copyright registration protection of digital images, realizes the protection of digital image copyright through a small amount of encryption and decryption operations and a small amount of information transmission. After analysis, our copyright protection system has high computing efficiency and security, the calculation efficiency and advantages are more prominent when transmitting large data information, and it has good application prospects.
