Face recognition based door locking system

The security sector is experiencing diversification. This has brought about
the need to review the reliability of already existing systems and look into the possibility of creating better systems that are smarter and more secure. The old door security systems made use of keys, locks and chains. However, the locks can be easily broken and keys can get stolen or can be duplicated. In order to overcome this drawback, mechanical locking system was
introduced, that is, latches were used. Latches had better security than the
locks. Although, latches cannot be broken as easily as the locks, they make
the use of keys, which are not so reliable and can get stolen. Further, to
avoid these drawbacks, password based system was introduced. This
system used numeric combination to permit entrance to user.

But security is entirely based on confidentiality and the strength of the password.Modification was made in the password from numeric to alpha-numeric.Security describes protection of life and property. moved to biometric security system to ensure better security. Biometric security system includes fingerprint based system was the first biometric locking system. Using the fingerprints of a person for unlocking the door is main parameter for this system. However, like any other systems, they also have drawbacks. Fingerprints of a person can be duplicated. This can lead to opening of the door for unauthorized person. Finally research moved to image processing system. This system provides high security. When a person wants to access his locker, initially at the main door of locker and PIR sensor will be placed. This sensor will sense the body temperature of a person, standing near the door. And then, his/her image will be captured by
the camera installed at the main gate. This image will be given to the PC
where the Python software will compare this image with the authentic
images stored in the PC. If authentic, then only the door will open otherwise
it will remain closed and the alarm will buzz for further action.
