Introduction
Nothing is 100% secure. Passwords can be guessed, safes can be easily broken into, and locks can be picked – these are just a few examples. How can you protect what you value and love if nothing is completely secure? One proven way is to use a fingerprint scanner. Not so long, fingerprints were taken if an individual was being suspected.
But now, it’s innocent individuals who’re turning to fingerprint scanners to protect themselves and their valuable things. As a result, fingerprints are everywhere, from laptops and mobile phones to ATM machines and high-security buildings. Let’s discover what fingerprint scanners are and how they work.
What is a Fingerprint Scanner?
Its name suggests what it is. A fingerprint scanner is an electronic device used to recognise and identify people by capturing their fingerprints. They manage to identify each individual since fingerprint patterns are unique for everyone.
A fingerprint scanner scans, processes and compares fingerprints to those stored in a database to identify a person. Several fingerprint scanners are available, which include the following:
- Dynamic output
- Mechanical
- Thermal
- Capacitive
- Optical reflective
How Does a Fingerprint Scanner Work?
While several fingerprint types are available, they all have one main objective – to capture fingerprints, process and identify an individual. A fingerprint scanner functions by obtaining an image of a finger and determining whether the pattern of the valleys and ridges in the photo matches one of those pre-scanned and stored in a secure database.
Only specific features unique to each fingerprint are filtered before being saved as encrypted mathematical representations or biometric keys. No fingerprint image is saved; only a binary code (a series of numbers) is used for verification. The algorithm can’t be reconverted to the initial image, meaning no one can manage to duplicate the fingerprints.
Why Fingerprint Scanners?
Fingerprint scanners have become a more secure way to identify people. It’s a perfect alternative to remembering an endless list of user names, passwords and pins stored in databases. Their reliability, high-security level, hidden in-display designs, and increasing speed ensure that individuals and businesses can easily and securely identify people.
