Fingerprint Door Locks
What Is Fingerprint Door Lock and How Does It Work?
Fingerprint Door Locks – In the era of digitization, technology has become an integral part of our lives. As security is a significant concern in our daily lives, technology has embraced it too. Protecting our personal belongings and valuables has been the top priority for ages.
Today security is defined by a combination of hardware and software intelligence along with biometric involvement in their functionality. Here comes the concept of fingerprint door locks which use biometric identity in their functionality.
Fingerprint door lock – at a glance
Well, the term itself is self-explanatory. It is an exclusive door lock that uses the human fingerprint as the key to open a door. Now the next immediate question arises why fingerprint? To explain it – if you notice your fingers carefully, there are many line patterns, and these are called fingerprints.
No two persons have the same fingerprints. Hence, it’s a unique identity of a human being. The fingerprint door lock is the technical implementation of securing access to doors by recognizing and differentiating fingerprints.
How does Fingerprint door lock work?
Fingerprint door locks work in the following stages:
• Scanning of fingerprint
• Converting scanned data into numerical form
• Matching the numerical data through a matching algorithm
In the first step when someone places the finger onto the scanner for the first time, it scans the person’s fingerprint and saves the numerical template of the scanned data in the memory. Later, when someone puts their finger on the sensor of the lock, it matches the numerical data obtained through fingerprint with the saved values. In case of a match, the lock grants access to the user. Otherwise, the door remains locked.
Now, how does this matching happen? Instead, how does the sensor differentiate between two different fingerprints? Well, it occurs by the Minutia matching technique. Minutia is an essential feature of a human fingerprint which includes Ridge ending and Ridge bifurcation. It is widely used in forensics and biometrics to compare two fingerprints.
In the case of a fingerprint door lock also, the same information is stored in the memory. When there is a match found a green LED blinks up and the door opens. Overall it is a speedy process that takes only a few seconds.
Sometimes fingerprint scanners are made based on an optical system or are capacitor-based.
Are fingerprint door locks a safe way to go?
No doubt fingerprint door lock is a safe biometric way to ensure the security of valuable belongings or homes. However, it is not impossible to find a way through. If someone can copy an image of the actual person’s hand, they can open the door without consent.
Also, in case of a hand injury or scar, sometimes the scanner may not acknowledge the real person. Also, the battery of the door lock may be discharged, and it may start malfunctioning. Hence, it is always a good idea to install a fingerprint door lock with a keyhole provision.
Conclusion: To conclude, Fingerprint door lock is a simple, non-expensive, and easy-to-use security system. Installing fingerprint door locks helps you avoid hassles regarding key loss, is more reliable, and offers superior security. It is definitely worth the money, considering its benefits.
