Biometric Locks: Basic Categories and Features

With the increase in the number of smart software hackers, digital lock systems are currently under threat. This has prompted inventors to enhance the digital locks with the more efficient biometric technology. This feature makes use of unique aspects of the user themselves to unlock the doors.

By using a biometric door lock in Singapore, passwords and PINs are rendered unnecessary. This rules out any kind of intrusion by hackers. These systems cannot be unlocked without the physical presence of the registered users.

Types of Biometric Identification

Based on the biometric used for identification, a biometric door lock can be classified under three main categories:

• Fingerprint Identification: The database of the lock contains a list of users with saved images of their fingerprints. To unlock the door, the user will have to press their finger to the lit panel. The input image is then matched with the images existing in the database. It offers precise fingerprint authentication. In case the input image matches that on an existing user, the old image is replaced with the new one. Thus, it not only provides excellent security but also automatically updates itself

• Retinal Scan: It is well known that the pattern of capillaries in a person’s retina is unique; even identical twins cannot have the same pattern. Also, it remains the same from birth to death. So some digital door locks have been fitted with a camera to scan the retina of the user. The input image is then matched with those existing in the database. This process is extremely speedy and precise. This technology is used in places that require extreme security, for instance, high-profile research labs, and intelligence services and so on.

• Speaker Recognition: It is based on the fact that the acoustic patterns of speech of different people are different. It takes into account vocal quality, pitch as well as speaking style. The user provides a pre-saved command and it is matched with system records to verify who is speaking. Sometimes, the vocal quality might be taken into consideration instead of the provided command. Often, an identity or some unique PIN is provided by the user and the device authenticates the speaker. This system is highly flexible and can provide security measures on multiple levels to suit the needs of the user or the institution.

Biometric security systems are used by high-profile institutions to protect confidential material. But their use can be extended to domestic spaces as well, so that one does not have to waste their valuable time worrying about the hackers, the criminals or security from them.
