Embodiment Construction

[0075] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0076] First, the general idea of ​​the present invention is described. The present invention provides an encryption method, a server, a decryption method and a terminal. First, the server generates an encrypted image using encryption technology, and then places the encrypted image in a terminal product. In the subsequent process, the terminal decrypts the encrypted image according to user instructions, and The decrypted image is displayed, so that the user can perform anti-counterfeiting authentication on the terminal product by viewing the decrypted image. Wherein, the key for decrypting the encrypted image is obtained by the terminal and the server during the interaction process.

[0077] Such as figure 1 Shown, be a kind of encryption method of the...

Abstract

Disclosed is an encryption method. The encryption method comprises: obtaining a binary image as an original image; arranging the original image according to a coordinate sequence to generate a first one-dimensional array; obtaining the panel number of a terminal; according to the panel number of the terminal, encrypting the first one-dimensional array to generate a second one-dimensional array; and in accordance with the coordinate sequence, enabling the second one-dimensional array to generate an encryption image. Also disclosed at the same time are a decryption method, a server, a terminal and an encryption / decryption system. The present invention can be applied to the digital image anti-counterfeiting technology of terminal products, and the application is simple.

Description

technical field [0001] The invention relates to the field of images, in particular to an encryption method and server, a decryption method and a terminal. Background technique [0002] As an important branch in the field of information security technology, digital watermarking technology has been widely used and studied deeply. It embeds an invisible mark into multimedia information products without causing perception to identify the original author's ownership of the work or verify the integrity of the information. [0003] With the continuous development of the terminal market, it is more and more important to strengthen the protection of property rights of terminal products. However, in the prior art, the digital image anti-counterfeiting technology is relatively complicated. Contents of the invention [0004] The invention provides an encryption method and server, a decryption method and a terminal which are easy to apply. [0005] In one aspect, an encryption method...
