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. Specifically include the following steps:

[0018] Step 1: Open the Windows command line program 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 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 e...

Abstract

A block chain-based mobile projection authorization management method relates to the field of block chain technology, the field of digital film copyright protection, and the field of data security. The encrypted distributed storage of authorization information and the authorization processing on nodes are completed through the cooperation of blockchain technology and IPFS technology. Specifically, it includes obtaining and uploading authorization information, and encrypting it and storing it in the blockchain IPFS storage system; user devices are respectively connected to the blockchain network to form a user interaction network and a device light node network. After the user node submits an authorization application, the authorization operation of the authorization information is carried out through identity authentication and device authentication. After the authentication is successful, the device light node can obtain the authorization information and perform corresponding decryption processing. This method utilizes the storage model of blockchain and IPFS to improve the capacity storage problem of blockchain and improve the scalability of blockchain.

Description

technical field [0001] The invention relates to the field of block chain technology, the field of digital movie copyright protection, and the field of data security, especially an authorization management method for a movie streaming projection system. Background technique [0002] In recent years, the mobile projection of digital movies in rural areas has become a major cultural poverty alleviation project in rural my country. However, the existing mobile screening authorization management is based on traditional centralized database technology, adopting a centralized management model, and the authorization information is transmitted to the theater chain authorization receiving station through the Internet. With the rapid development of the Internet, the efficiency and security issues of screening authorization management have become increasingly prominent, and there are problems such as artificial data tampering and illegal authorization. Therefore, it is imminent to esta...
