Abstract

The invention discloses a database data synchronization method and device and a computer storage medium. Time stamps and version hash values are set for version information of databases of the Internet of Things terminal device and the cloud server. Only when the timestamps and the version hash values of the respective version information of the databases are consistent, synchronization of database is performed. The cloud server only sends different data between the data of the database corresponding to the latest update record of the cloud server and the data of the database of the version corresponding to the successful consistency check to the Internet of Things terminal device for synchronization. Through the scheme, data synchronization of the cloud server and the database of the Internet of Things terminal device can be ensured, and after consistency verification is successful, the cloud server only sends the difference data between the latest version of the database and the database when consistency verification is successful, so that the resource occupancy rate can be reduced, and the synchronization speed can be increased.

Description

technical field [0001] The embodiments of the present application relate to the technical field of the Internet, and in particular, to a database data synchronization method, device, and computer storage medium. Background technique [0002] With the development of the Internet and electronic camera technology, face recognition technology has been widely used, for example, it can be applied to various fields that require identification such as customs, banks, and access control. [0003] The regional feature analysis algorithm widely used in face recognition technology, which integrates computer image face recognition processing technology and biostatistics principles, uses computer image processing technology to extract portrait feature points from videos, and uses the principles of biostatistics Analyze and establish a mathematical model, that is, a face feature template. Use the built face feature template and the face image of the person under test to conduct feature an...
