Abstract

The invention relates to a digital rights management method of a binding terminal, comprising following steps: the terminal extracts terminal information of the terminal and stores and sends the information to the server; the server receives and stores or contrasts the information; the server uses the received terminal information as a key to encrypt media files that the terminal wants to download; the terminal uses the terminal information as the key to decrypt the encryption media files which are downloaded and stored in the terminal information and display the encryption media files. The invention also discloses a system used for the method and a handheld terminal. Implementing the digital rights management method of the binding terminal, the system and the handheld terminal of the invention is provided with following beneficial effect: the invention can prevent the media files from being illegally copied after being downloaded, so as to really guarantee practical copyright benefits of program content providers.

Description

technical field [0001] The present invention relates to a digital rights management method, system and terminal thereof, more specifically, to a digital rights management method, system and a hand-held terminal for binding a terminal. Background technique [0002] The working principle of digital rights management technology (DIGITAL RIGHT MANAGEMENT DRM) is to first establish a media file authorization center, encode and compress the digital program content, and use the key (Key) to be encrypted and protected (lock), and the encrypted media file header It stores the KeyID and the URL of the program authorization center. When the user is ordering, according to the KeyID and URL information in the file header, the relevant key decryption (unlock) can be sent after the verification and authorization of the media file authorization center, so that the file can be played. The files to be protected are encrypted, and even if they are downloaded and saved by the user, they cannot...
