Embodiment 1

[0031] Embodiment 1, refer to Figure 1-2 Describe this embodiment, a privacy data protection method, comprising the following steps:

[0032] Step 1: Establish a Fabric blockchain network, which includes the following steps:

[0033] Step 11. Define the necessary configuration information such as channel and identity, and start the ordering service node and peer node;

[0034] Steps 1 and 2, define a smart contract containing a private data set, in which a specific function needs to be defined to save the user-generated key key and the random value nonce;

[0035] Specifically, the key key and the random value nonce are stored in the private data set as private data.

Abstract

The invention provides a privacy data protection method, an electronic device and a storage medium, which belong to the technical field of computer applications. First, the Fabric blockchain network is established; thirdly, the specific function is called; thirdly, it is judged whether the private data occupying the storage space meets the preset standard, and the ciphertext is stored in the form of key-value pairs under the chain; thirdly, the private data If the data can meet the preset standard, then replace the original function parameters with the private data ciphertext and random value; finally, according to the replaced parameters and random values, obtain the key value of the corresponding private data stored under the chain, the private data Authorized nodes can download the ciphertext of private data from off-chain, and decrypt the ciphertext according to the key to obtain the original text of the private data. The technical problem of insufficient storage space of the private database existing in the prior art is solved. Realize off-chain storage with sufficient storage space and high flexibility.

Description

technical field [0001] The present application relates to a data protection method, in particular to a privacy data protection method, an electronic device and a storage medium, belonging to the technical field of computer applications. Background technique [0002] Hyperledger Fabric is an open-source enterprise-grade permissioned Distributed Ledger Technology (DLT) platform designed for use in enterprise environments and has become one of the most popular enterprise-grade blockchain platforms. [0003] Although blockchain technology has significantly improved the security and reliability of data, the current storage scalability of blockchain technology is poor, and it will increasingly occupy a large amount of storage space of massive nodes. On-chain storage and off-chain storage is an efficient solution to improve the scalability of blockchain storage. It transfers the data content in the block body from the original block body to the off-chain storage system. The block b...
