Abstract

Embodiments of the invention provide a data retention and verification method and device. The method comprises the following steps of: determining a retention characteristic value uniquely corresponding to retention data by a server according to a preset rule, writing the retention characteristic value into a transaction record of an appointed transaction, and writing the transaction record into a block chain to be stored; when the server verifies verification data, determining a to-be-verified characteristic value uniquely corresponding to the verification data according to the previously adopted manner, and comparing the to-be-verified characteristic value with the retention characteristic value stored in the transaction record of the block chain so as to verify the verification data. Through the method, the data stored in the block chain is unchangeable, and the server can attach the retention characteristic value uniquely corresponding to the retention data into the transaction record to be stored in the block chain, so that the reliability of the retention characteristic value is ensured, and the reliability of carrying out data verification on the verification data by the server through the retention characteristic value is further ensured.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a method and device for storing and verifying data. Background technique [0002] With the continuous development of computer technology, the data storage capacity of the database is continuously improved. At present, people can store a large amount of user data in the data storage device, so as to realize the unified management and application of these data. [0003] Since a large amount of user data is stored in the database, the security capability of the database storage data has been attracting attention, and people have been working hard to improve the security performance of the database, so that the database can be more reliable in terms of data storage security. However, the data stored in the current database is not tamper-resistant. For example, the administrator of the database can modify the historical data operation records at any time, and it is often d...
