In today's society, it seems that all people need to do is move their fingers. With just a few taps on our phones, we can shop online, pay bills, and even get in touch with someone on the other side of the world. Today, our fingers take on a whole new role. Fingerprints are increasingly replacing passwords, and fingerprint locks are becoming a popular trend. Think about it. Why remember a password when you can just use your finger and not have to remember anything? Also, fingerprints seem more secure because no two people have the same fingerprint. But in reality, it can be dangerous to use fingerprint recognition instead of strong passwords. The truth is that strong passwords are much more secure than any fingerprint.
How does fingerprint lock work?
As the user places his or her finger on the device multiple times to capture the fingerprint, the device extracts the fingerprint features and the more distinctive features of the fingerprint are recorded and enhanced. The image of the fingerprint is then converted into a binary code and encrypted so that the device can identify and quickly compare it with the user's finger to produce a matching score. Depending on the match score, the system will allow or deny access to the device.
Does fingerprint lock really secure?
Fingerprint scanners are not infallible. The biggest problem with fingerprint recognition is that it often fails to distinguish between a real finger and a fake finger. If someone has access to a user's fingerprint, or even a similar fingerprint in general, they may create a fake finger, which could fool the scanner.
In addition, people unknowingly leave their fingerprints everywhere. They can't do anything about it; their fingerprints are a part of them. It's basically like writing your password on a sticky note wherever you go. Anyone, with a little patience, can access your personal fingerprint.
As fingerprint recognition and biometrics become more prevalent, criminals will have more incentive to try to forge fingerprints. And there are many ways to easily spoof fingerprint readers.
So why not use a combination lock. A good, strong password is more secure than fingerprint identification.
