Problems solved by technology

[0004] Therefore, copyright information, as part of resource data, is rarely protected during transmission. In this way, it is easy to obtain, resulting in the leakage of copyright information, which is not conducive to copyright protection and also affects the distribution of resources.

Embodiment Construction

[0027] In the embodiment of the present invention, an authentication server is added to the data information distribution system, and each publishing subsystem must be authenticated and authorized by the authentication server before it can distribute data information and obtain corresponding copyright information.

[0028] According to the characteristics of resource distribution in the digital publishing industry, the data information distribution system includes: two-level or multi-level publishing subsystems. There can be only one, two, or more publishing subsystems in each level of publishing subsystems. Each publishing subsystem has a unique identifier. The data information is distributed downwards according to the publishing subsystem level, that is, it is distributed downwards from the highest-level publishing subsystem.

[0029] The authentication server manages the authorization and authentication information of all publishing subsystems, as well as the identificatio...

Abstract

The invention discloses a method, a system and a device for data information distribution in order to improve a security level of data information and strengthen copyright protection. The method comprises the steps that a current level publishing subsystem acquires first authorization authentication information from an authentication server; at least one copyright element in a first copyright information file is encrypted according to an encryption public key in the first authorization authentication information; a copyright information ciphertext is generated, and sent to a next level publishing subsystem; the next level publishing subsystem decrypts the copyright information ciphertext according to a decryption private key in second authorization authentication information acquired from the authentication server; and a corresponding second copyright information file is obtained.

Description

technical field [0001] The present invention relates to the technical field of digital information, in particular to a method, system and device for distributing data information. Background technique [0002] Copyright protection is especially important in the digital publishing industry. However, when the publishing subsystem generally publishes its own resources, it often pays too much attention to the protection of the data content of the resources itself, but rarely pays attention to the concealment of copyright information. [0003] At present, the publishing subsystem adopts the method of data information distribution to publish resources. For example: use manuscript encrypted transmission mode to distribute data information between publishing subsystems at all levels. This data information distribution method only involves the encryption and distribution of the data content of the resource itself, but does not involve the protection and distribution of copyright in...
