Problems solved by technology

However, since the generation and management of such traces are mainly carried out in the user system, users may take some abnormal means to modify these traces of use, and then modify the browsing rights of digital works they enjoy.
Therefore, if an effective method cannot be adopted to safely generate and save usage traces at the user level, it will not be possible to safely and effectively control the user's digital work browsing authority, so that the copyright protection of digital works cannot be effectively carried out.
[0010] At the same time, in the existing technology, when users use digital content, they may not need to use all the digital content, but only need to use a part of the entire digital content, and sometimes due to "mistaken clicks", etc. The reason is wrong use of some digital content. Since the existing digital trace technology does not support the "partial use" of digital content, whether it is only a piece of content or a "misclick", the user's Corresponding to the authority of the entire digital content, so that users suffer unnecessary losses

Embodiment 1

[0056] The method for generating and managing digital content use traces based on trusted computing technology of the present invention can be divided into two parts: a method for generating use traces and a method for managing use traces.

[0057] The use trace of digital content is generated during the storage and use of digital content. Therefore, the method for generating digital content use trace of the present invention uses a digital content browsing system including TPM to protect key data of digital content, including the following step:

[0058] Step S110, obtain the digital content including authority information, and generate a key for encrypting the obtained digital content; generate an initial usage trace matching the obtained digital content, store the key, use The key encrypts the acquired digital content, and forms and stores a content / key address.

[0059] The step S110 includes the following steps:

[0060] Step S111: The digital content browsing system in...

Embodiment 2

[0076] Please refer to image 3 , which is a flowchart of a method for generating digital content usage traces based on trusted computing technology in the second embodiment of the present invention. Here, the steps in the second embodiment that are the same as those in the first embodiment will not be repeated, and only the steps that are different from those in the first embodiment will be described.

[0077] The difference between the second embodiment and the first embodiment is:

[0078]In step S112 of the second embodiment, firstly, there is a content splitting process, that is, the digital content obtained by the user is divided into several content segments according to certain principles, wherein each content segment contains the contents of the digital content using the digital content. Information that requires permission. The principle of splitting the above content can be based on the amount of data, etc. In this embodiment, the acquired digital content is split...

Abstract

The invention relates to a digital content use trace generation and management method based on dependable computing technology, which comprises the following procedures: acquire digital content and generate a cipher key for encryption; generate an initial use trace, store the cipher key and conduct encryption with the cipher key, so as to form and store a content / cipher key address; in using the digital content, compare the use access information and use trace to judge whether or not to read the content / cipher key address; address and read the digital content and cipher key, decrypt and use the digital content to form the use trace of digital content. The management method comprises the following procedures: a digital content browse system with TPM generates the use trace; encrypt the use trace and store it in binding with a platform status; collect the platform status when the device is restarted; when users start the browse of digital content via the digital content browse system with TPM, judge whether or not to allow the binding of use trace.

Description

technical field [0001] The invention relates to the field of trusted computing, in particular to a method for generating and managing digital content usage traces based on trusted computing technology. Background technique [0002] With the rapid development of computer and Internet technology, the browsing of digital works based on computer technology has been popularized all over the world, and the issues of copyright use and copyright protection of digital works caused by this have also attracted more and more attention. [0003] The copyright use and copyright protection of digital works are mainly carried out in three layers, which are content production layer, content transmission layer and content application layer. [0004] Among them, in the content production layer, the distribution unit of digital works mainly adds permission restrictions to the digital works produced, that is, copyright restrictions. These restrictions are preset and can be carried out in accorda...
