Human have several parts that are unique from the other’s identity.  One of the widely used is the fingerprint biometrics, Fingerprint biometrics is a dynamic technology that is being adopted into new markets and applications at a rapidly increasing pace.  With lesser price this keyless lock (Fingerprint biometrics) has emerged as the most popular biometric technology to protect confidential computer information as they enable convenient security for desktop and Internet applications, it is also widely used for different applications not only for securing company files or personal files but this keyless lock is also used for office and home door lock which is also a lot reliable compared to an ordinary door lock.

Fingerprint door locks for homes allow security control over individual’s access without the need to replace locks when a key is lost or stolen.  Employees that are required to carry an electronic or magnetic ID to enter their office will also appreciate the convenience associated with a fingerprint activated lock.  This will also allow bigger companies to save from replacement of magnetic ID’s over and over again.

What advantage and disadvantages do you get from having a finger print biometrics?

Universality
Advantage: Fingerprint is one factor to consider in biometrics because almost all can use this keyless lock technology.
Disadvantage:   Those with skin diseases or any disorders can’t use the technology.

Uniqueness
Advantage: Each person has unique finger print even twins don’t have the same finger prints.
Disadvantage: Because of the uniqueness, stolen finger prints also mean your access is stolen for good.  Law enforcement officers found that any smooth, hard surface touched by a human hand would yield fingerprints made by the oily secretion present on the skin. When these so-called latent prints were dusted with powder or chemically treated, the identifying fingerprint pattern could be seen and photographed or otherwise preserved.

Performance
Advantage: A lot secure compared to any ordinary locks.  Fingerprint scanners are more accurate, faster and require less computation and storage compared to other biometrics.
Disadvantage: Like any other devices, keyless lock can be damaged.  Fingerprint recognition systems for large-scale deployments require a large amount of computational resources.

Though there are a lot of feed backs regarding the keyless lock fingerprint authentication there are still ways to strengthen the system and one method for improving the accuracy of biometric authentication systems is to enforce “two-factor authentication”, that is one must authenticate by some biometric form as well as use a password or posses a token.
