Embodiment Construction

[0017] The present invention provides an authorization information management method based on blockchain and IPFS. The system flow chart is as follows image 3 Shown. It includes the following steps:

[0018] Step 1: Open the command line program of windows and start the Ethereum environment. Create a new account on the Ethereum blockchain and unlock it, open another command line program, execute truffle.cmd compile to compile the contract, and then execute truffle.cmd migrate to deploy the contract on the Ethereum blockchain.

[0019] Step 2: Open another windows command line program and run the authorization information data acquisition interface script and the data storage query interface script in the Node.js environment. The authorization information data acquisition interface will start monitoring and wait for the upload of authorization information.

[0020] Step 3: Obtain authorization information through the authorization information acquisition interface, and encrypt the ...

Abstract

The invention discloses a block chain-based mobile projection authorization management method, and relates to the technical field of block chains, the field of digital film copyright protection and the field of data security. Encrypted distributed storage of authorization information and authorization processing on nodes are completed through cooperation of the block chain technology and the IPFS technology. The method specifically comprises the following steps: obtaining and uploading authorization information, encrypting the authorization information, and storing the encrypted authorization information into a block chain IPFS storage system; and the user equipment being respectively accessed to the block chain network to form a user interaction network and an equipment light node network. And after the user node proposes an authorization application, authorization operation of authorization information is carried out through identity authentication and equipment authentication. And after the authentication is successful, the device light node can obtain the authorization information to perform corresponding decryption processing. According to the method, the storage models of the block chain and the IPFS are utilized, the capacity storage problem of the block chain is solved, and the expandability of the block chain is improved.

Description

Technical field [0001] The invention relates to the field of blockchain technology, the field of digital movie copyright protection, and the field of data security, in particular to an authorization management method for a movie mobile projection system. Background technique [0002] In recent years, the mobile screening of rural digital films has become a major cultural poverty alleviation project in rural my country. However, the existing mobile screening authorization management is based on the traditional centralized database technology and adopts a centralized management model. The authorization information is transmitted to the theater authorized receiving station via the Internet. With the rapid development of the Internet, the efficiency and safety of the management of screening authorization have become increasingly prominent, and there are problems such as artificial data tampering and illegal authorization. Therefore, it is urgent to establish a safe and reliable mobi...
