Embodiment 1

[0033] figure 1 It is a structural block diagram of the examination information recording system provided by the embodiment of the present invention, and is described in detail as follows:

[0034] The examination information recording system includes a management server, a plurality of examination information recording nodes and a plurality of vehicle-mounted terminals installed on examination vehicles; the plurality of examination information recording nodes include examination information recording preferred nodes and other examination information recording nodes, so The other exam information nodes are exam information nodes other than the exam information record preferred node among the plurality of exam information nodes; the management server and the exam information record preferred node adopt an alliance chain to build a chain to form a block chain network;

[0035] The management server is used to establish a genesis block, and assigns an account number and a key to...

Embodiment 2

[0051] figure 2 It is the implementation flowchart of the test information recording method provided by the embodiment of the present invention, and is described in detail as follows:

[0052] S201. The management server establishes a genesis block, and assigns an account number and a key to each of the preferred nodes of the examination information record, authorizes the preferred node of the examination information record to join the blockchain network, and A smart contract is issued on the network, and the smart contract is provided with a node identification that allows access to blockchain ledger information;

[0053] S202. The vehicle-mounted terminal obtains examination information, and uploads the examination information to the preferred node for recording examination information, where the examination information includes the name and ID number of the examiner, examination results, and image information inside and outside the vehicle during the examination;

Abstract

The invention is applicable to the technical field of information security, and provides a test information recording system and a test information recording method based on a block chain. The systemcomprises a management server, a plurality of test information recording nodes and a plurality of vehicle-mounted terminals. The management server and the examination information record node adopt theunion chain way to establish the chain, and form the block chain network; The management server is used for establishing the creation block; The vehicle terminal obtains the examination information;as the examination information record node records the examination information, an Examination Information Recording Request is initiated, transaction unique identification number is obtained,, the test information and a transaction unique identification number are packaged to form transaction data, if the transaction data is selected as the bookkeeping node, the transaction data is packaged according to the block data structure to generate a block, the generated block is broadcast to the rest of the examination information recording nodes, and the generated block is added at the end of the existing block chain. The invention enhances the safety of the examination information recording system.

Description

technical field [0001] The invention belongs to the technical field of information security, and in particular relates to a blockchain-based examination information recording system and examination information recording method. Background technique [0002] After the relevant provisions of the Ministry of Public Security on the process of obtaining a motor vehicle driver's license were changed from the previous Decree No. 111 to Decree No. 123, the judging method of the driving skill test process of motor vehicle candidates has been changed from manual to computer-based, and the entire test is required All the information of the process can be traced to the source at any time, that is to say, the test process of any candidate can be completely played back or restored at any time, so that it can be re-examined or corrected correctly. [0003] However, in the existing examination information recording system, the examination information is easy to be tampered with, which is no...
