Face recognition based on auto-switching magnetic door lock system using microcontroller

Face recognition system is widely used for human identification due to its capability to measure and subsequently identifies human identification especially for security purposes. This paper presents the development of Graphical User Interface (GUI) based on face recognition system and Peripheral Interface Controller (PIC) as an input/output carrier to switch on/off magnetic lock for door lock security system. The development is implemented by interfacing GUI built in MATLABR2009a with microcontroller to auto-switching magnetic lock for door lock security system. USB serial communication is used to interface between GUI and PIC microcontroller that allows input data transmission from GUI to microcontroller. The developed system shows that the auto-switching mode transmission being implemented via PIC microcontroller and USB serial communication cable. It was also found that GUI can successfully switch on and off the magnetic lock when an authorized image from GUI database is identified.
