Abstract

The invention relates to a digital content coding decoding system and a digital content coding decoding method, which performs coding of a digital content by using a device number of a device downloading the digital content, a user ID, and a reading deadline set by a server, and performs decoding of the coded digital content by using a special reading module cooperating with the device number, the user ID and the actual time data so as to restore and read the digital content. The digital content coding decoding system of the invention has the characteristics of real-time coding and decoding of the digital content, and crack difficulty, and thus realizes the effect of real protection of the digital content from being stolen.

Description

technical field [0001] The present invention relates to an encoding and decoding system and encoding and decoding method, in particular to a digital content encoding and decoding system and a digital content encoding and decoding method. Background technique [0002] Due to the high development of network and cloud computing technology in today's society, the application of digital content is boundless. But also because of the maturity and universalization of technology, it is very easy to obtain digital content. Although this is of great help to the popularization of knowledge and technological progress, it is a great challenge to the protection of intellectual property rights. [0003] To implement education or digital content circulation via the Internet, in addition to contract restrictions, content providers usually code (also known as encryption) the digital content for protection. After the user obtains the encoded digital content, it must be decoded first to read t...
