• Security of human life and property is one of the paramount challenges facing individuals, corporate organizations or any nation.
• The problem of insecurity of properties and intrusion into premises dates back as far as the existence of man. One major means
of achieving security within a building is through the door access control.
• The door access control provides security by limiting
unauthorized access and possibly taking record of those that passes through it
Working
• Biometrics Door Lock mainly works on the basis of highly
programmed device which will allow the authentication only if the user
is authorized.
• The authorization process in the Biometric Door Lock is not done
by any physically existing key but it is done by fingerprint, facerecognition or iris-scan.
• At first, the user needs to enter the biometrics of people he/she
wants to give authorization in the database. And then place the lock.
• Whenever the person needs to unlock the lock, he/she is advised to
scan his/her biometrics to get the access granted.

1.Availability of Multiple Fingerprints
2. Built-In-Arm
3. Live detection of biometrics
4. Availability of Mechanical Key as a back-up
5. FRR – False Rejection Rate
6. Proper Power Source
security threats
• There is no doubt that Biometrics Door Locks are better in
comparison to Normal Door Locks.
• But in this era of rapidly growing
technology, there are many threats in using a Biometric Door Lock.
• Even if the entire Biometric system works on the principle of
programs which are developed by a professional, there is a possibility
for hackers to find a trapdoor in it and gain access illegally.
• In fingerprint-based door locks, there is possibility of duplicating
an authorized user’s print and then gaining unauthorized access.
