A network examination system based on a block chain and a method for managing the network examination by using the network examination system

Abstract

The invention relates to a network examination system based on a block chain and a method for managing the network examination by using the network examination system, belonging to the technical fieldof teaching management equipment. The system adopts double-block chain design, including a data storage layer, a block chain core layer, a block chain application layer, a block link interface layer,a business system layer and a system user layer. The API interface of the data storage layer is connected with the API interface of the core layer of the block chain, the core layer of the block chain is connected with the application layer of the block chain, and the application layer of the block chain is connected with the interface layer of the block link through the API interface. The blocklink interface layer is connected with the service system layer to realize the inquiry and writing of the block chain service. The business system layer is connected with the system user layer, whichprovides the interface between the user and the network examination service. The invention can prevent information from being lost or tampered with maliciously, construct a safe, reliable and non-tamper examination credit system, simplify the network examination management process, improve the network examination organization efficiency, and provide high-efficiency, convenient and humanized examination service for examinees.

Description

technical field [0001] The invention relates to a block chain-based network examination system and a method for managing network examinations by using it, and belongs to the technical field of teaching management equipment. Background technique [0002] The Ministry of Education's "National Medium- and Long-Term Educational Reform and Development Plan (2010-2020)" clearly proposes to build a "overpass" for lifelong learning, to promote vertical connection and horizontal communication of various levels of education, to provide multiple choices, and to meet the needs of individuals. Diverse learning and development needs. Examination, as an important evaluation link in the process of talent training, also needs to adapt to the needs of reform and development, and provide flexible, convenient, reasonable and fair personalized examination services for all kinds of learners. Traditional online examinations generally adopt a unified examination time, unified organization of propo...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to propose a blockchain-based network examination system and a method for managing network examinations by aiming at the problems that examination information and examinee performance data can be tampered with and the examination process cannot be traced in the existing network examination system , adopts a dual-blockchain design, stores candidate information and score data through the test taker score chain SBC, and realizes the openness and transparency of test taker score data; stores the test process, question bank, and test paper information through the test business chain BBC to realize the traceability of the whole process of the test business Reliability, using asymmetric encryption technology to ensure the data security of the question bank and test paper information
