Abstract

The invention provides a key generation and distribution method based on graph recognition, and relates to the field of digital copyright protection. In order to ensure the generation and secure distribution of an e-book key, the scheme provided by the invention is as follows: at an e-book downloading stage of a user, converting a first page of an e-book to be downloaded by the user into an image by a server; selecting color information in the image in combination with e-book information; using information scrambling color information of user equipment as a key to encrypt the e-book; and storing the e-book information in other color information layers of the image to be distributed with the encrypted e-book; at an e-book reading stage of the user, identifying key information in a graph in the first page of the downloaded e-book by a client, and decrypting the e-book. The key generation and distribution method provided by the invention is used for not only guaranteeing the complexity of the key, but also guaranteeing the secure distribution and storage of the key.

Description

technical field [0001] The invention relates to the field of digital copyright protection, in particular to a key generation and distribution method based on graph recognition. Background technique [0002] With the development and application of Internet technology, computer technology, streaming media technology and compression technology, mobile terminals are becoming more and more popular, and the era of digital publishing has arrived. More and more readers choose to download e-books to read. However, the convenience of e-book transmission also makes the copyright protection of e-books more and more difficult, which seriously damages the interests of publishers and authors, and also hinders the development of digital publishing to a certain extent. [0003] The purpose of digital copyright protection is to prevent pirates and users from arbitrarily copying digital content among various terminals, and to protect the copyright of digital content. The technologies involved...
