Embodiment Construction

[0034] Below, the present invention will be further described in conjunction with the accompanying drawings and specific embodiments.

[0035] refer to figure 1 As shown, according to an embodiment of the present invention, an electronic distribution system is provided, and the electronic distribution system includes four types of nodes: a copyright authorization center, a content processing node, a device certificate issuing node, and a terminal device (such as a reader).

[0036] Among them, the copyright authorization center is generally located in the central computer room, and is used to provide copyright object (RO) files, issue digital certificates for users, and provide database services. The copyright object (RO) file is generated based on various information of the user in the order (when the user clicks to subscribe through the client, various information such as the user name, terminal model, and subscribed electronic media label are packaged to form an order and s...

Abstract

The invention provides an electronic issuing system. The electronic issuing system comprises a content processing node and terminal equipment, and is characterized in that the electronic issuing system further comprises a copyright authorizing center and an equipment certificate issuing node, wherein the copyright authorizing center is used for generating a copyright object file, issuing a digital certificate for a user, providing a corresponding private key and providing database service; the content processing node is used for encrypting a publication by using a secret key (Key) so as to generate a content object file; the equipment certificate issuing node is used for receiving the digital certificate and the corresponding private key issued by the copyright authorizing center and burning the digital certificate and the corresponding private key into the terminal equipment; and the terminal equipment is used for acquiring the content object file and the copyright object file, and thus acquiring the secret key (Key) through the private key in the terminal, and decrypting the publication in the content object file into a plaintext. The invention further provides a corresponding electronic issuing method for the publication. Through the electronic issuing system and the electronic issuing method, issued information can be encrypted in a certification process; encrypting levels can be graded; and software encryption and hardware encryption are combined to improve the encrypting security and the encrypting flexibility.

Description

technical field [0001] The present invention relates to the technical field of electronic distribution systems, in particular, the present invention relates to an electronic distribution system and publication distribution method. Background technique [0002] The electronic distribution system is a news information electronic dissemination and Internet digital publishing system with electronic dissemination and personal terminal display as the main body. Different from traditional paper media, digital media-based network distribution brings challenges to the copyright control of publications. Due to the shared and virtual nature of the network, if certain technical means are not adopted, electronic publications will inevitably be pirated. rampant. At present, the traditional electronic distribution system mainly includes: a database module, an information distribution module and a user terminal. Technology protects the copyright of publications. In this system, the most ...
