Embodiment Construction

[0017] The present invention will be described in detail below in conjunction with the embodiments and accompanying drawings.

[0018] see figure 1 , is a schematic diagram of a digital copyright protection system 10 , including a copyright owner 100 , a service providing device 200 and a user terminal 300 .

[0019] The copyright owner 100 is used to provide the digital file to the service provider 200 .

[0020] The service providing device 200 is responsible for publishing digital files, and the service providing device 200 encrypts the digital files and publishes the digital files through the network. The service providing device 200 is also used to obtain the hardware information of the user terminal 300 (such as the serial number of the motherboard of the user terminal 300, the serial number of the hard disk, etc.), and generate an authorization file according to the hardware information, and the authorization file is used for decrypting the digital file. And uniquely ...

Abstract

The invention relates to a copyright protection method, which comprises the following steps of: sending a request for downloading an encrypted digital file to a service provision device by a user terminal; downloading the encrypted digital file and an authorization file corresponding to the digital file from the service provision device, and embedding hardware information of the user terminal into the authorization file; and judging whether hardware information in the authorization file is consistent with the hardware information of the user terminal or not, and when the hardware information in the authorization file is consistent with the hardware information of the user terminal, permitting the user terminal to obtain the authorization of the digital file. The hardware information of the user terminal is embedded into the authorization file, and the corresponding digital file can be used only when the hardware information in the authorization file is consistent with the hardware information of the terminal, therefore, the copyright protection method can prevent from illegally copying the digital file. The invention also provides the service provision device for preventing the user terminal from illegally copying the digital file and the user terminal capable of eligibly copying the digital file.

Description

technical field [0001] The invention relates to the technical field of digital copyright protection, in particular to a service providing device, a user terminal and a copyright protection method enabled during the transmission of digital files. Background technique [0002] Most of the current data does not adopt copyright protection technology, so digital files can be copied from a computer or a portable terminal to other computers or portable terminals at will, resulting in illegal duplication. Illegal duplication often seriously infringes the interests of digital file providers and relevant rights holders. In order to deal with this situation, realize the protection of digital files and prevent the illegal circulation of content, digital copyright management technology is born accordingly. This kind of technology will need to carry out The copyright-protected digital files are encrypted and encoded and sent to the user terminal, and the user uses the obtained key to decr...
