Abstract

The invention provides a server side for providing digital contents in an encryption mode. The server side for providing the digital contents in the encryption mode comprises a user management module, an authorization module and a content module. The server side divides the digital contents into a plurality of blocks by the use of data segmentation technique, each content block is encrypted and decrypted in order by the use of the information related to client's hardware ID (identification), and the hardware ID information comprises CPUID (central processing unit identifier) information, hard disk volume number information, BIOS (basic input output system) information, network card MAC (media access control) addresses, IP (internet protocol) addresses and combination of above information. The server side has the advantages that with the client's hardware ID information used during the authentication process and the encryption process, security during the communication process is ensured, and encryption efficiency is improved.

Description

[0001] [0002] This application is a divisional application of the invention patent application with the filing date: October 25, 2010, the application number: 201010518019.7, and the invention title "Digital Content Encrypted Transmission Method and Server End". technical field [0003] The invention relates to a server end providing digital content in an encrypted manner. Background technique [0004] With the rapid development and popularization of the Internet, more and more users use the Internet to transmit data, release resources, and download resources. It is not uncommon to download various digital resources such as music, film and television dramas or computer software from the Internet. Although the rapid development of the Internet facilitates users' demand for quick access to information, it also brings challenges to the copyright protection of various digital resources. In daily life, there are various websites that provide unauthorized music resources, fil...
