Fingerprint Door Lock

Abstract

Since ancient times, security has been and remains a problem for homes, offices and stores. Everyone is afraid of a stranger breaking into their home or office without their knowledge. Normal doors can be equipped with locks that can be selected with an alternate key. You can find alternatives to this system, such as password or the pattern system of locks. This system can be exposed and opened again. Therefore, a solution to this problem ( ) may be to combine the 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 duplicacy in such key is not possible. Also, this system will not lead to problems like losing keys because we do not require carrying keys if this system is used instead of traditional locks. So, using arduino we will try to implement the system with features which will increase the security level Key Words: Home/office security system, Fingerprint door lock, Arduino based project
