Data evidence storage method based on block chain

Abstract

The invention discloses a data evidence storage method based on a block chain. The data evidence storage method comprises the following two stages: stage 1, generating a contract file: step 1, selecting a contract template; a user selects the following five contract templates as required according to an actual application scene: an identity registration template, a data release template, a data update template, a data evaluation template and a data check template; 2, configuring a contract template; 3, generating a contract code; 4, installing and deploying an intelligent contract; and stage 2, intelligent contract calling: after the intelligent contract is successfully deployed, calling a method provided by the intelligent contract by the user, running the intelligent contract, and completing data uplink evidence storage. The method is based on a block chain technology, an editable data storage excel contract template contract file is provided for a user, the user can complete data storage intelligent contract development by using simple template configuration, and credible storage of user data is realized.

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
