Transmission encryption method and system based on private block chain, medium and electronic equipment

Abstract

The invention provides a transmission encryption method, device and system based on a private block chain, and electronic equipment, and provides the transmission encryption method and system based on the private block chain, a medium and the electronic equipment according to the confidentiality grade attribute condition of a to-be-uploaded file and the identity, address and uploading time of an uploader. Setting a file confidentiality level, and obtaining a confidentiality level attribute condition of the to-be-uploaded file; according to the attribute condition, not encrypting a low-confidentiality file, and encrypting a high-confidentiality file; the encryption method comprises the step of adding digital watermarks to audio and video files for encryption. According to the private block chain-based transmission encryption method and system, the medium and the electronic equipment, a decentralized and high-security file storage mechanism is formed by using a block chain technology, and in the data transmission process, the risk of leakage of commercial core data can be effectively avoided, core confidentiality can be protected, and stable development of enterprises can be promoted.

Description

technical field [0001] The invention relates to the technical field of blockchain data transmission, in particular to a transmission encryption method, system, medium and electronic equipment based on a private blockchain. Background technique [0002] Blockchain is a new application model of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. From a technological perspective, blockchain involves many scientific and technological issues such as mathematics, cryptography, the Internet, and computer programming. From the perspective of application, in simple terms, blockchain is a distributed shared ledger and database, which has the characteristics of decentralization, non-tampering, traceability throughout the process, traceability, collective maintenance, openness and transparency, etc. These characteristics guarantee The "honesty" and "transparency" of the blockchain lay the foundation for the cr...

Problems solved by technology

[0007] Applied to enterprise servers, the cost of cloud servers is low but the security is also low, while the cost of local servers is relatively high but the security is also improved but the utilization rate is low. How to store low and high confidentiality files and data, To avoid leakage, a private blockchain can be used to store confidential files. Among them, high confidentiality files are stored on the blockchain in a specific way to ensure that they will not be leaked
