Abstract

This application discloses a blockchain-based information update method and server. The method includes: obtaining the first broadcast message sent by the operator node from the blockchain network; The value obtained by the hash operation, the second encoding is the value obtained by the terminal encoding the information of the second vehicle according to the preset method; obtain the pre-stored first storage information and the second storage information, and according to the preset method, respectively Encoding the first storage information to obtain a third code, and encoding the second storage information to obtain a fourth code; performing hash operations on the third code and the fourth code respectively to obtain a third hash value and a fourth hash value ;According to the preset time order, sort the third hash value and the fourth hash value to obtain the second sorting result; update the license plate number of the first vehicle and the second vehicle according to the second sorting result and the first sorting result license plate number.

Description

Technical field [0001] The present application relates to the field of communication technology, and in particular to a block-based information update method and a server. Background technique [0002] At present, the Ministry of Public Security is notified to launch a new measures for the reform of the 10 Ministry of Public Security. Among them, these 10 new measures include a 5-class well-organized business, 5 convenient services. Among them, the business of different places includes: owners can update their original license plate numbers to other vehicles they own, so that the owner can keep their own original license plate number unchanged. [0003] Since the user name in the block chain network is not the real name of the user, if the update of the license plate number is implemented by the block chain network, the confidentiality of the information is poor, and the owner's privacy information is leaked, causing the user experience. . Inventive content [0004] To this end,...
