A method and system for updating personal biological information based on blockchain

Abstract

The invention discloses a method and system for updating personal biometric information based on blockchain, comprising: presetting a preset collection age stage of biometric information and a preset collection biometric feature range to obtain preset body biometric stage data; Preset body biometric stage data collection age feature range; collect personal biometric information in the age feature range; dynamically update personal biometric age feature attributes according to personal biometric age feature attribute data and personal biometric attribute characteristics of each age stage ;Convert the dynamic update data of personal biological information into the dynamic corresponding unordered deprivation field of biological information, the dynamic correspondence of biological information to the disordered deprivation field through blockchain encryption operation, and dynamically correspond to the deprivation key and general area according to the biological information of the person The verification result of the blockchain key confirms whether the new block generation and blockchain transaction settlement activities of the biological information blockchain system can be performed.

Description

technical field [0001] The present invention relates to the field of blockchain biological updating, and more particularly, the present invention relates to a method and system for updating personal biological information based on blockchain. Background technique [0002] At this stage, blockchain and biometric identification technology have been widely developed, but the update and change of biometric information is still a technical problem that blockchain biometric identification needs to face and solve; The changes are great, how to update the biological information on the blockchain, and the technical problems based on the blockchain and personal biological information update have yet to be solved, including: how to collect biological information and biological characteristics and obtain personal biological information Age characteristic attribute data technical problems It needs to be further improved and perfected; how to dynamically correspond the biological informat...

Problems solved by technology

[0002] At this stage, blockchain and biometric information technology have been widely developed, but the update and change of biological information is still a technical problem that blockchain biometrics needs to face and solve; There are big changes, how to update the biometric information to the blockchain, the technical issues based on the blockchain and personal biometric information update have yet to be resolved, including: how to collect biometric information and biometric features and obtain the technical issues of personal biometric information age characteristic attribute data It needs to be further improved and perfected; how to dynamically correspond to the encryption operation of the blockchain with biological information, and how to generate new blocks in the blockchain system of biological information and transaction settlement activities in the blockchain through the verification results still need to be further resolved; therefore, it is necessary Propose a method and system for updating personal biometric information based on blockchain to at least partially solve the problems existing in the prior art
