Using Edge Computing and face recognition technology to build intelligent security system is an important research content in modern artificial intelligence application field. In this paper, an insensitive SMS notification system of multi-face recognition is constructed, which collects real-time face recognition data, then analyzes the face information, and sends the SMS to the specified person according to the analysis result. The system in this paper can not only be used for independent short message notification function, but also can be integrated into other traditional face recognition security system.
