Abstract

The invention discloses a block chain private data protection method and device, equipment and a medium. The method comprises the steps that two transaction parties on a block chain carry out transaction to acquire generated transaction information, generate symmetric encryption keys, encrypt private data through the secret key, encrypt the symmetric encryption secret key through a public key of an access end of the private data, package and upload the encrypted private data and the symmetric encryption secret key, and decrypt the private data through respective private keys of the access endto obtain the private data when the private data needs to be checked. Wherein the access end comprises a transaction end and a supervision end, the method can play a role in protecting private data, and meanwhile, the supervision end can conveniently supervise the private data.

Description

technical field [0001] The present invention relates to the field of block chains, in particular to a method, device, device and medium for protecting private data in block chains. Background technique [0002] Blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. Blockchain is an important concept of Bitcoin. As the underlying technology of Bitcoin, it is a series of data blocks associated with each other using cryptographic methods. In the formation process of Bitcoin, a block is a storage unit one by one, which records all the communication information of each block node within a certain period of time. Each block is linked by a random hash, and the latter block contains the hash value of the previous block. With the expansion of information exchange, one block is followed by another, and the result is called a block. chain. Since each data block conta...
