Abstract

The invention relates to the data processing field, in particular to a digital film secret key distributing method, device and system based on a management website. The method includes the steps that the authorization request for a digital film sent by a second client is received, and authorization information corresponding the digital film is generated according to the authorization request; the authorization information at least comprises authorized information of a playing device, theater information and digital film information; according to the digital film information in the authorization information, content secret keys corresponding to the digital film information are acquired, and the content secret keys are processed to generate secret key files; the secret key files are sent to a first client corresponding to the information of the playing device through a network so that after the first client acquires the secret key files, the acquired encrypted digital film can be decrypted through the secret key files and the digital film corresponding to the authorization information of the first client can be acquired. With the method, device and system, safety of digital films in the propagation process is effectively improved, and safety of the copyright of digital films is protected.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a management website-based digital movie key distribution method, device and system. Background technique [0002] With the maturity of digital multimedia technology, the digital film industry began to grow. Because of the advantages of relatively easy production, flexible processing, convenient storage and transmission, and good image effects, digital movies are more and more widely used and better meet the cultural needs of the broad masses of the people. [0003] Digital movies are gradually developing in the direction of high-definition and high-quality. The initial stage of digital movie development is to adopt the MPEG2 standard with a resolution of 1920×1080. Later, the "Digital Cinema Specification (v1.0)" formulated by DCI (Digital Cinema Initiative Alliance) in 2005 proposed 2K (resolution 2048×1080) and 4K (resolution 4096×2160) digital movies based on JPEG200...
