The invention discloses a 
monitoring system and device based on human face large data. The 
system is composed of a front-end real-time acquisition 
system and a human face monitoring center 
management system. The front-end real-time acquisition 
system distributively collects a human face video or a high-definition human face image and individual basic information, and carries out uploading to a human face comparison 
server. The human face comparison 
server establishes a local human face 
data management system for uploaded human face data, and periodically carries out 
data synchronization with the human face monitoring center 
management system to synchronize added human face data to a 
central database. The 
central database uses a simple and efficient human 
face matching algorithm, or merges and classifies human face data based on a unique identification code. Based on the classified human face large data, 
data analysis, 
blacklist large-scale early warning and other functions are carried out. The system provided by the invention effectively solves the problem that current urban human face monitoring systems are independent of each other, have separated data, and are not conducive to the construction of an accurate criminal suspect 
tracking system.
