Embodiment 1

[0048] This embodiment provides a digital resource copyright protection method, which can be used in the copyright protection of massive digital resources based on hardware storage devices, the method flow chart is as follows figure 1 shown, including the following steps:

[0049] S01. Use the first key to encrypt the content of the digital resource on the digital resource. Here is the copyright protection encryption performed on the content of the digital resource, for example, the first key is key A, and the encryption method is DRM encryption.

[0050] S02. Use the second key to encrypt the first key, and generate an encryption certificate according to the encrypted information.

[0051] When mass-producing digital resources, such as when a batch of e-books is to be authorized in batches to several mobile phones, the above-mentioned key A is encrypted twice at this time, and the second key here is key B. When resources are authorized in batches, key B is selected to encry...

Embodiment 2

[0058] This embodiment provides a method for opening a copyright-protected digital resource, which can be used to open a digital resource mass-produced using the method in Embodiment 1 on a hardware storage device. The flow chart of the method is as follows figure 2 shown, including the following steps

[0059] S11. Read the authorization file, and judge whether the authorization file matches the unique identifier of the current hardware storage device. When matching, execute step S12, and exit the program directly if not matching, or prompt that the reason for exiting is not matching.

[0060] When accessing copyright-protected digital resources on the hardware storage device, start the copyright protection program, read the authorization file first, and enter the next step when the authorization file matches the unique identifier of the current hardware storage device.

[0061] S12. When the authorization file matches the unique identifier of the current hardware storage d...

Embodiment 3

[0068] This embodiment provides a digital resource copyright protection device, the structural block diagram is as follows image 3 shown, including:

[0069] The digital resource encryption unit 01 is used to encrypt the content of the digital resource using the first key for the digital resource;

[0070] The secondary encryption unit 02 is configured to use the second key to encrypt the first key, and generate an encryption certificate according to the encrypted information;

[0071] A transmission unit 03, configured to send the encrypted digital resource and the encryption certificate to each hardware storage device;

[0072] An authorization file generation unit 04, configured to bind the second key with the unique identifier of the hardware storage device, and generate an authorization file for the hardware storage device.

[0073] Wherein, the digital resource encryption unit adopts DRM encryption.

Abstract

The invention provides a digital resource copyright protection method and device. Digital resource content encryption is carried out to a digital resource by means of a first secret key; the first secret key is encrypted by means of a second secret key, and an encryption certificate is generated in dependence on encrypted information; the encrypted digital resource and the encryption certificate are sent to each hardware storage device; the second secret key is bound with a unique identification of the hardware storage devices, and an authorization file of the hardware storage devices is generated. According to the scheme, when the digital resource is licensed to a plurality of mobile terminals in a batch manner, only two times of encryption work are needed, one authorization certificate is made for each hardware storage device, encryption in a batch manner is achieved, time spending on binding the hardware storage devices with the digital resource is greatly reduced, the production efficiency of massive copyright protection resources based on bound storage devices is improved, the production cost is reduced, at the same time, resource copyright protection is guaranteed, the resource is prevented from being copied and embezzled, and dependence of hardware resource protection on hardware equipment is avoided.

Description

technical field [0001] The invention relates to the field of digital resource protection, in particular to a digital resource copyright protection method and device. Background technique [0002] With the development of information technology, the way and speed of dissemination of information resources are getting faster and faster. As a kind of information resources, digital resources are becoming more and more popular among people, such as e-books, e-journals, e-newspapers, online news, etc. It has become an important source of information for people in their daily lives. However, due to the wide distribution channels and fast speed of digital resources, how to effectively protect the copyright of digital resources has become an important problem to be solved urgently. [0003] With the rapid development of hardware technology and the popularization of the network, network applications based on hardware storage devices are becoming more and more extensive, such as data st...
