Embodiment Construction

[0034] The digital file network distribution system realized by the present invention firstly has the function of protecting the file when the user stores the digital file, and secondly has the function of protecting the file during the transmission process from the distributor to the user. An implementation of the present invention is introduced below. This implementation is based on the implementation described in Chinese Invention Patent 200910147998.7 and the implementation described in Chinese Invention Patent 200910008922.6. The specific content is as follows, wherein the digital file in a special form is referred to as Special forms for digital files:

[0035] Components of the distribution system

[0036] In this implementation, the hardware composition of the distribution system includes computer equipment for making special forms of digital files (called distributor computers), network servers for disseminating special forms of digital files (called download servers)...

Abstract

The invention relates to a digital file distribution method based on a network, which comprises the following major steps: 1, processing the content of a file to be distributed until the content is in such a state that the content can not be directly acquired by an access program; 2, transmitting a file the content of which is in a processed state; 3, after a user acquires the file the content of which is in a processed state, recovering the content of the file, and simultaneously storing the file in a storage environment which can prevent the file from being copied and moved and check the access program; and 4, in the storage environment, providing an access to the content of the digital file for an application program. By using the method, the invention ensures that the digital file can be protected in the whole distribution process.

Description

technical field [0001] The content of the present invention relates to a digital file network distribution system. Specifically, a method for distributing digital files through the network is described. Among them, through encapsulating and distributing digital files, storing them in a storage environment that can restrict illegal copying, restricting illegal movement, and checking access programs, etc., digital files will not be illegally copied during the entire distribution process such as dissemination, storage, and use. The purpose of protecting file content. Background technique [0002] Chinese invention patent 200910008922.6 introduces a method of providing a custom access control method in a file system. The file system that provides user-defined access control methods has the function of supporting the access control verification process corresponding to user-defined file access operations. [0003] A file system that provides custom access control methods provi...
