How Do Fingerprint Door Locks Work

What are fingerprint door locks.

How do fingerprint door locks work.

For the door lock to work you first have to enter your fingerprint data. Since fingerprints are unique to each person this biometric method of entry is both more secure and more efficient than keys too. To unlock it you can simply place your finger on the pad. The way fingerprint scanners scan is different actually.

This process can take place either on a host computer or a local processor in applications such as a fingerprint locks. Basically fingerprint locks operate by scanning and converting your fingerprint data into a numerical template. Fingerprint door locks work just like the biometric sensors on your phone. Then when you shut the door on your house the lock engages.

Let s start with the definition. For these reasons many people believe these types of locks to be a secure option. Based on this biometric locks can recognize and separate different users. Once you place your finger onto the scanner for the first time the conversion into numerical data takes place and the fingerprint template is saved.

So during the first time the fingerprint door lock accumulates the fingerprint pattern data and converts the data into number format usually binary format. First you need to set the lock for the fingerprint door lock. Fingerprint locks are almost impossible to deceive and can detect when a door closes and lock after five seconds. The codes range in complexity from four to eight digits or more.

First a user enrolls in the system by providing a fingerprint sample. This process is then repeated every time you want to grant someone access. The sensor captures the fingerprint image which is then interpreted by an algorithm and the representative features extracted to a data file. Locks which employ them have either a physical or virtual keypad you type the code into and provided it s the right one the door opens.

Basically fingerprint locks operate by scanning and converting your fingerprint data into a numerical template. Although the name in itself is pretty self explanatory a fingerprint door lock may be defined as a system which grants access to authorized personnel by virtue of recognizing their unique fingerprints. Biometric info relies on a system that is able to detect if a print is a match without having to send info to a source. Fingerprint door locks scan the fingerprint of a person to open the door rather than using a key.

Fingerprint locks scan the patterns of the finger converts the pattern into numerical data templates. That way the lock can identify each person. These types of scanners can be tricked by presenting a photo of the print. There are the optical scanners and they in essence take photos of your finger and then store the photo for matching.

The data file then serves as the user s individual identification template.
