Problems solved by technology

The security of not all encryption algorithms can be proved mathematically. The recognized high-strength encryption algorithms and implementations are often recognized by everyone after a long period of full practical demonstrations in all aspects, but this does not mean that they absolutely do not exist. Vulnerabilities, in fact, the security of cryptography is often provided through the mathematical problems on which the algorithm depends, rather than by keeping the implementation process of the algorithm secret, so it is still impossible to guarantee the credibility of the data before it is uploaded to the chain. Guarantee whether the data source is authentic and credible. The data after being uploaded to the chain can be guaranteed to be immutable through cryptographic methods, but it cannot guarantee whether the source of "first-hand data" is authentic or credible.

Abstract

The invention discloses a building project scene type evidence storage non-tampering method based on a block chain technology. The method comprises the following steps: step 1, carrying out authoritydivision and user authentication; step 2, accessing a hardware device of an operation site to the block chain; step 3, predefining various initial parameters about projects, tasks, logs and problem flows in engineering, and initializing a constructional engineering flow into the intelligent contract; step 4, performing data entry operation on the data representing the condition of the operation site through mobile equipment or mobile software; and step 5, performing data verification and uploading. The invention further discloses a corresponding system, computing equipment and a computer readable storage medium, and it can be guaranteed that the user truly stores and records information in real time according to project requirements in a specific time period and in a specific scene according to permission in a non-tamperable mode. Meanwhile, by utilizing the traceability characteristic of the block chain technology, the situation of user data uploading can be reviewed, and the projectprogress can be evaluated.

Description

technical field [0001] The present invention generally relates to the field of block chains, and in particular to a method and system for scene-based certificate storage of construction projects based on block chain technology and cannot be tampered with. Background technique [0002] Blockchain is widely regarded as a distributed data store that can serve as a solution to many problems in asset registration and transaction execution. At present, the non-tamperable and traceable features of blockchain technology have been affirmed by the industry. The application prospect of blockchain technology is broad, and all walks of life are actively looking for solutions from blockchain technology to solve industry pain points. [0003] In the current technical scheme, the important position of cryptography-related security technology in the entire information technology field is inevitable, and blockchain technology relies heavily on the research results of cryptography and securit...
