Problems solved by technology

[0002] Geotechnical engineering survey data is highly reusable data and has high utilization value, so it is impossible to freely exchange data between survey units
At present, there are mainly two modes of exchange of survey data: 1. The survey institutes contact each other separately, and then exchange data with each other; 2. Unify the application to the government department that manages survey data; the two methods are basically through WeChat, QQ, and email Although it can satisfy the sharing of survey data, it cannot satisfy the security, credibility, freedom and verifiability of survey data sharing, which is mainly reflected in the following three problems:
[0003] 1) Before the data is shared, the source of the data cannot be effectively verified, such as information such as the collection unit, collection person, and collection equipment;
[0004] 2) In the process of data sharing, the data exchange information cannot be effectively saved, such as: information such as the parties to the data exchange, the content of the exchanged data, and the time;
[0005] 3) After the end of data sharing, evaluation information on data quality or data provider credit cannot be effectively provided

Embodiment

[0049] Example: such as figure 1 , 2 As shown, this embodiment specifically relates to a blockchain-based survey data management system, the survey data management system includes an authorization module, an acquisition module, a storage module, a verification module, a sharing module, and an evaluation module, wherein:

[0050] Authorization module: grant unique identity information to each survey unit, and form encryption key pairs (encrypted private key and encrypted public key) and signature keys of each survey unit through encryption technology based on the unique identity information; at the same time, based on the identity of each unit The information generates unique identity information for the employees and equipment of the unit, and based on the unique identity information, encryption key pairs and signature keys for employees and equipment are formed through encryption technology. Encryption technology can use any one of RSA, Elgamai, ECC.

Abstract

The invention discloses a reconnaissance data management system based on a block chain and a working method thereof. The reconnaissance data management system comprises an authorization module, an acquisition module, a storage module, a verification module, a sharing module and an evaluation module, the storage module comprises a local storage unit and a block chain storage unit; and the sharing module comprises a data query and display unit and a data exchange unit. The system has the advantages that the whole system comprises authorization, collection, storage, verification, sharing and evaluation, private storage of survey data is guaranteed, data sharing among different survey units is supported, and the efficiency and reliability of the data are improved; with the help of a block chain technology, information of an investigation unit, investigation personnel, investigation equipment, investigation data and a data exchange process is encrypted and uploaded to a chain, so that the non-modifiability and the verifiability of the uploaded data are ensured; each investigation unit, the investigation personnel and the equipment are endowed with unique identities, and the identities cannot be modified, so that the uniqueness of a data source is ensured.

Description

technical field [0001] The invention belongs to the technical field of geological survey, and in particular relates to a blockchain-based survey data management system and a working method thereof. Background technique [0002] Geotechnical engineering survey data is highly reusable data and has high utilization value. Therefore, various survey units cannot exchange data freely and safely. At present, there are mainly two modes of exchange of survey data: 1. The survey institutes contact each other separately, and then exchange data with each other; 2. Unify the application to the government department that manages survey data; the two methods are basically through WeChat, QQ, and email Although it can satisfy the sharing of survey data, it cannot satisfy the security, credibility, freedom and verifiability of survey data sharing, which is mainly reflected in the following three problems: [0003] 1) Before the data is shared, the source of the data cannot be effectively ve...
