ARDUINO BASED FINGERPRINT DOOR LOCK SYSTEM
International Research Journal of Modernization in Engineering Technology and Science · 2022
From earlier times as well as till now, security was an important issue of concern in our households and also in office, shops, etc.Everyone has a fear of unauthorized person entering to their home or office without their knowledge.The normal door can be fitted with locks which are capable of breaking with the use of an alternate key.Alternatives to this system can be found like the password or pattern system in the locks which again has the possibility of getting exposed and opening the lock.So, a solution to such problems can be by combining door lock with biometrics.Biometric verification is any means by which a person can be uniquely identified by evaluating one or more distinguishing biological traits.Unique identifiers include fingerprints, hand geometry, earlobe geometry, retina and iris patterns, voice waves, DNA, and signatures.Here we will use fingerprint for biometric verification as it is one such thing which is unique to every individual and the use of fingerprint as the key to door locks can overcome the security problem of unauthorized people trespassing to our homes, shops, offices, etc to a great extent as duplicity in such key is not possible.Also, this system will not lead to problems like losing keys because we do not require carrying keys.This system can be used instead of traditional locks.So, using arduino we will try to implement the system with features which will increase the security level.
