Abstract
The present invention relates to one kind of digital content packaging method with authority description, and b information propagating technology. The packaging method includes: compressing the original digital content; adding digital watermark; enciphering the digital content with embedded watermark; adding operation authority description to the enciphered content; adding the authority limitation description of using digital content tool; and adding the separation description of the complete digital content. Unlike traditional digital content enciphering packaging thought, the present invention packages various authority requirement information to realize the effective protection and management of the digital content in the whole consuming value chain.
Description
Technical field
The invention belongs to the information dissemination technology field, the digital content packing method of the sharp interpellation of the cum rights under particularly a kind of digital content consumer environment.
Background technology
Along with Internet development, the construction of family's broadband network, the consumption of digital content is more and more, lacks a large amount of without restriction on the internet bootleggings of digital content and the propagation of right control, serious harm national cultural security.
Though the packing of traditional encrypt digital content can be protected digital content to a certain extent, can not effectively manage digital content.Simultaneously, in case encrypted digital content is decrypted, digital content no longer is protected.In the case, pirate phenomenon remains incessant after repeated prohibition, and the trend that grows in intensity is more arranged.
Therefore stop stretching of pirate phenomenon, manage and protect digital content effectively, realize that the protection and the management of digital content in whole consumption value chain is the key technical problem that needs to be resolved hurrily.
Summary of the invention
The objective of the invention is for solving the problems of the technologies described above, propose the digital content packing method of the sharp interpellation of a kind of cum rights.This method simultaneously with various possible right control information packings, thereby realizes effective protection and the management of digital content in whole consumption value chain by in traditional encrypt digital content packaging method.
The digital content packing method of the sharp interpellation of a kind of cum rights that the present invention proposes may further comprise the steps:
(1) original digital content is carried out data compression process, comprising digital video content compression, digital audio content compression and digital text content compression (correlated digital content compression method directly adopts traditional existent method to realize);
(2) digital content of having compressed is added digital watermarking (by digital watermarking is embedded in the digital content, the owner information of digital content and digital content binding, copyright information is accompanied by digital content from producing disappearance, and the embedding grammar of correlated digital watermark directly adopts traditional existing method to realize);
(3) digital content of embed digital watermark is encrypted (by the encryption to digital content, digital content no longer exists with form expressly, it takes the form of sightless ciphertext form, and the correlated digital content enciphering method directly adopts traditional existing method to realize);
(4) described encrypted digital content being added various claims to digital content manipulation describes;
(5) claim limitation that described encrypted digital content is added using the digital content instrument requires description;
(6) described encrypted digital content interpolation is split description to complete digital content.
In above-mentioned steps (4), add various claims and describe, specifically may further comprise the steps digital content manipulation:
(4.1) operation requests that digital content may be received abstract come out from digital content lists a digital content permit operation tabulation;
(4.2) carry out or finish concrete right or the identity sign that this action need has for each the operation mark in the tabulation of digital content permit operation;
(4.3) this digital content permit operation tabulation is added in the described digital content packing.
Add that in above-mentioned steps (5) claim limitation of using the digital content instrument is required to describe, specifically may further comprise the steps:
(5.1) a permission to use digital content instrument tabulation is listed in digital content compressed format and the operational rights requirement of supporting according to compressed format and each instrument of described digital content;
(5.2) mark out for each instrument in the permission to use digital content instrument tabulation that this instrument of use carries out or complete operation need have what concrete right or identity sign;
(5.3) this permission to use digital content instrument tabulation is added in the described digital content packing.
In above-mentioned steps (6), add the method that complete digital content is split packing, specifically may further comprise the steps:
(6.1) according to the actual conditions of described digital content consumption, as the full disclosure of predicting or introduce unconditional or low condition, promptly the different piece of digital content is given the description of different claims with sub-fraction content in the digital content;
(6.2) the corresponding different claims descriptions of the different piece of described this digital content are added in the described digital content packing.
Characteristics of the present invention and technique effect:
The inventive method breaks through traditional encrypt digital content packing thought; when digital content is packed; not only add enciphered message and digital watermark information; simultaneously with various possible claim information package, thereby realize effective protection and the management of digital content in whole consumption value chain.
