Problems solved by technology

This method limits the copying of data resources by binding data resources and device hardware; and sets the expiration time for data resources, which mainly makes the limited use of data resources by comparing the download time with the current time of the machine
But this mode has certain defects: all data resources are downloaded to the client (such as a personal computer) and stored on the hard disk, which provides a carrier for cracking and copying, and ultimately makes it difficult to guarantee the copyright protection of digital resources
This method can prevent users from copying and deciphering data resources after downloading them through "Digital Rights Management (DRM)" technology (such as adding anti-copy codes to network digital resources), which limits the illegal copying of data resources to a certain extent.
[0006] However, when the "data stream" method is used, the encryption method of the data resource itself is also limited. Generally, the data header is encrypted. The entire data file, and the use of data resources by client programs is affected by network conditions

Abstract

The invention discloses a data resource anti-copying encrypted transmission system and a method. The system comprises a client device (1) and a network end device (5), wherein the client device (1) transmits a request to the network end device (5) to download data files into a temporary storage; the client device (1) comprises a reader (14), and the reader (14) reads and displays the data files in the temporary storage, and has the one or multiple functions of prohibiting printing, transferring and copying; the network end device (5) comprises a network server (3) and a data resource management server (4); after receiving the request, the network server (3) transmits a request for calling the data files from the data resource management server(4); the data resource management server (4) transmits the requested data files to the network server (3) according to the call request, wherein each data file has encryption protection; and after further encrypting the data files, the network server (3) transmits the encrypted data files to the client device (1) through a network. The invention effectively enhances the data file transmission safety and reduces the possibility of copying and decryption.

Description

[0001] The said application is a divisional application, its parent application number is 200510117041.X, and the filing date is 2005.10.28. technical field [0002] The invention relates to a method and equipment system for preventing network data resources from being copied during online use and being intercepted during transmission. It is mainly used in the network system of the "server-client" mode. technology between media. Background technique [0003] With the networkization and digitization of a large number of information resources, illegal copying of other people's digital works and violations of the legitimate rights and interests of data resource owners are becoming more and more serious. In order to protect the interests of right holders and prevent network resources from being illegally copied, it is necessary to impose certain restrictions on the use of network resources and the means of data transmission. [0004] In the prior art, there are two ways of usin...
