In this modern technical world IOT is playing a significant role in security and privacy purpose like defense security, building security, official security, home security etc. In this article we have proposed an IoT-based smart door lock system using face lock recognition. An automated smart door with face recognition is a software to identify house owner to lock and unlock the door. This type of smart door lock presents high-level home security and privacy as now a days modern technology eliminates the need for keys or passwords. In face lock recognition system, there are some challenges and vulnerabilities in duplicate or false image verification like user’s JPEG, PNG photography identification while the user does not present in front of the camera. We have proposed an innovative access control model based on machine learning techniques with IoT.
