Document Type and Number:
WIPO Patent Application WO/2021/104345
Kind Code:
A1
Abstract:
Disclosed is an anti-counterfeiting and encryption method based on a local random image transformation technique, which method belonging to the technical field of anti-counterfeiting and encryption. In the present invention, local replacement is performed on random images (that is, the arrangement structure of pixels in a space is changed or pixel values are changed), and then, two random images are used to store corresponding information; and "locally scrambled" portions of the images contain a part of key information. However, since the images are still random, there is still no explicit information display in the images; and even if the information is intercepted during a transfer process, the content of the information cannot be known without the original first random scatter diagram, and the existing information also cannot be tampered with. In the present invention, a user does not need to memorize any password; and the present invention is convenient for operation, simple to calculate and suitable for use in a mobile terminal, such as a mobile phone.
