Abstract

The present invention relates to a digital content packing method with right description, which belongs to the technical field of information diffusion. The present invention comprises that data compression treatment is carried out for the original number content; the number watermark is added in the compressed number content; the number content in which the number watermark is embedded is encrypted; various right requirement descriptions for a number content operation are added in the number content which is encrypted; a right limitation requirement description for using a number content tool is added in the number content which is encrypted; a separation description for the intact number content is added in the number content which is encrypted. The method of the present invention breaks the traditional number contents encrypted packing thought. When the number content is packed, the encrypted information and number watermark information are not only added, and different probable right requirement information is packed simultaneously. Thereby, the effective protection and the management of the number content in a whole expense value chain are realized.

Description

A digital content packaging method with claims

technical field

The invention belongs to the technical field of information dissemination, and in particular relates to a digital content packaging method with claim descriptions in a digital content consumption environment.

Background technique

With the development of the Internet and the construction of home broadband networks, the consumption of digital content is increasing. Digital content without rights control is illegally copied and disseminated in large quantities on the Internet without restriction, seriously endangering national cultural security.

Although traditional encryption and packaging of digital content can protect digital content to a certain extent, it cannot effectively manage digital content. Meanwhile, once the encrypted digital content is decrypted, the digital content is no longer protected. In this case, the phenomenon of piracy has been repeatedly banned, and it is even more intensified.

Therefore, to prevent the spread of piracy, effectively manage and protect digital content, and realize the protection and management of digital content in the entire consumption value chain are major technical issues that need to be solved urgently.

Contents of the invention

The object of the present invention is to solve the above-mentioned technical problems, and propose a digital content packaging method with claims. The method simultaneously packs various possible rights control information in the traditional digital content encryption packaging method, thereby realizing effective protection and management of digital content in the entire consumption value chain.

A kind of digital content packaging method with claim description proposed by the present invention comprises the following steps:

(1) Perform data compression processing on the original digital content, including digital video content compression, digital audio content compression, and digital text content compression (the relevant digital content compression methods are directly implemented by traditional existing methods);

(2) Add digital watermark to the compressed digital content (by embedding the digital watermark into the digital content, the owner information of the digital content is bound with the digital content, the copyright information is accompanied by the digital content from generation to disappearance, and the related digital watermark The embedding method directly adopts traditional existing methods to realize);

(3) Encrypt the digital content embedded with the digital watermark (through the encryption of the digital content, the digital content no longer exists in the form of plain text, and its expression is in the form of invisible cipher text. The relevant digital content encryption method directly adopts the traditional Existing methods for implementation);

(4) adding various claim descriptions on digital content operations to the encrypted digital content;

(5) Adding a description of the restriction requirements on the use of digital content tools to the encrypted digital content;

(6) Adding a split description of the complete digital content to the encrypted digital content.

Add various claim descriptions on digital content operations in the above step (4), specifically including the following steps:

(4.1) Abstract the possible operation requests received by the digital content from the digital content, and list a list of permitted operations on the digital content;

(4.2) For each operation in the digital content permission operation list, mark the specific rights or identity marks that need to be owned to perform or complete the operation;

(4.3) Add the digital content permission operation list to the digital content package.

In the above step (5), add a description of the rights restriction requirements for the use of digital content tools, specifically including the following steps:

(5.1) List a list of licensed digital content tools based on the compression format of the digital content, the digital content compression format supported by each tool, and the operation requirements;

(5.2) For each tool in the list of licensed digital content tools, indicate what specific rights or identity marks are required to use the tool to perform or complete operations;

(5.3) Add the list of licensed digital content tools to the digital content package.

In the above step (6), a method for splitting and packaging the complete digital content is added, which specifically includes the following steps:

An embodiment of a method for packaging digital content with claims of the present invention includes the following steps:

(1) Perform necessary data compression processing on the original digital content, including digital video content compression, digital audio content compression, and digital text content compression. Related digital content compression methods are directly implemented using traditional existing methods, such as: Video compression methods such as DIVX and XVID, audio compression methods such as MP3;

(2) Add a digital watermark to the compressed digital content. By embedding the digital watermark into the digital content, the owner information of the digital content is bound to the digital content, and the copyright information is accompanied by the digital content from generation to disappearance. The embedding method is directly realized by traditional existing methods, such as: DES, AES, RSA, etc.;

(3) Encrypt the digital content that has been embedded with digital watermark. By encrypting the digital content, the digital content no longer exists in the form of plain text, and its expression is in the form of invisible cipher text. Realize the existing methods, such as: PATCHWORK, etc.;

(4) adding various claim descriptions on digital content operations to the encrypted digital content;

(5) Adding a description of the restriction requirements on the use of digital content tools to the encrypted digital content;

(6) Adding a split description of the complete digital content to the encrypted digital content.

Add various claim descriptions on digital content operations in the above step (4), specifically including the following steps:

(4.1) Abstract the possible operation requests received by the digital content from the digital content, and list a list of permitted operations on the digital content;

(4.2) For each operation in the digital content permission operation list, mark the specific rights or identity marks that need to be owned to perform or complete the operation;

(4.3) Add the digital content permission operation list to the digital content package.

In the above step (5), add a description of the rights restriction requirements for the use of digital content tools, specifically including the following steps:

(5.1) List a list of licensed digital content tools based on the compression format of the digital content, the digital content compression format supported by each tool, and the operation requirements;
