This paper explains the use of Biometric such as face recognition in automobiles such as cars. Nowadays the door lock in cars is released using keys, and then they can also be accessed using fingerprint, RFID etc. The use of keys to unlock the doors in cars is not efficient sometimes. Because the keys may be sometimes used by the wrong person. Hence this proposed system uses the face recognition for unlocking the doors in cars. This system is an efficient method to unlock the cars and at the same time provides security for the cars. Here raspberry pi is used for storing and processing.
