A blockchain-based data storage method

Abstract

The invention discloses a blockchain-based data storage method, which includes the following two stages: Stage 1, generating contract files: the first step, selecting a contract template; the user selects the following five contract templates as needed according to actual application scenarios : Identity registration template, data release template, data update template, data evaluation template, data inspection template; the second step, configure the contract template; the third step, generate the contract code; the fourth step, install and deploy the smart contract; Contract call: After the smart contract is successfully deployed, the user calls the method provided by the smart contract, runs the smart contract, and completes the data storage on the chain. This method is based on blockchain technology and provides users with editable data deposit certificate excel contract template contract files. Users can use simple template configurations to complete the development of data deposit certificate smart contracts and realize credible deposit of user data.

Description

technical field [0001] The invention relates to a blockchain-based data storage method. Background technique [0002] Risks in the existing data storage system: [0003] (1) Data ownership lacks public confirmation. Data release is submitted by the resource party independently. The system lacks unique identification and time series notarization registration of data. There may be problems such as repeated data registration and unclear ownership, which may lead to disputes over rights and responsibilities. [0004] (2) The boundaries of data security responsibilities are unclear. While sharing and transferring the evidence data, it also conveys security responsibilities. Undifferentiated data, one-way responsibility transmission, and simple auditing will inevitably lead to "connection" of security responsibilities, which is not conducive to data leakage traceability, but also dampens data providers positivity. [0005] (3) Data management and control responsibilities are t...

AI Technical Summary

Problems solved by technology

The data release is submitted by the resource party independently. The system lacks unique identification and time series notarization registration for the data. There may be problems such as repeated data registration and unclear ownership, which may lead to disputes over rights and responsibilities

[0004] (2) The boundaries of data security responsibilities are not clear

While sharing and transferring the evidence data, it also conveys security responsibilities. Undifferentiated data, one-way responsibility transmission, and simple auditing will inevitably lead to "connection" of security responsibilities, which is not conducive to data leakage traceability, but also dampens data providers enthusiasm

[0005] (3) Data management and control responsibilities are too centralized

Data access authorization, sharing and exchange, and log auditing are all completed on the information storage and certificate sharing platform, which requires resource providers and demanders to fully trust the platform, and the platform naturally assumes the main responsibility for management and control, which is often the case in practical applications. there will be problems

[0006] (4) Lack of an open and fair evaluation mechanism

Resource demanders do not have an open and fair way to evaluate data quality, and the centralized evaluation management mechanism lacks credibility, making it difficult to provide support for the platform to implement effective supervision and management of data providers

[0007] One of the core characteristics of blockchain technology cannot be tampered with, so blockchain data storage will be the main way of data storage in the future. However, most current blockchain-based data storage solutions have complex and difficult operations. , Unfriendly user experience and other issues
