Biometric devices use technology to identify people based on unique characteristics like fingerprints, iris scans, and voice recognition. They can be used for identification and verification, but accuracy and security are important factors to consider. Capacity is also an issue due to storage limitations.
Biometrics allows you to identify people based on unique characteristics. Examples include fingerprint scans, iris scans, and voice recognition. Biometric devices use technology to capture and process this type of information. Such devices can be found in airports, government buildings and law enforcement agencies.
Biometric devices typically capture information about a person the first time they use them. That information is linked to her, and other information can be linked, creating a file. For example, a person may need to enter a room that allows access after fingerprint verification. The first time, the person’s fingerprint will be recorded and attached to their name and photo. It’s also possible that other information, such as the make, model and registration number of your vehicle, could be linked to that fingerprint.
The two primary uses of biometric devices are identification and verification. These may look the same, but they can actually be very different. A facial recognition device can be used to identify a person entering a building and receiving an access pass. The information captured can only be useful later if it is necessary to identify who was given the access pass. If that person were to ever return, she could be subjected to the same process again.
Verification generally involves re-identifying someone using a biometric device. An example of such a case would be an iris scan that grants access to classified areas in a building. In this case, a person will use the device numerous times to confirm her identity and deem her qualified for entry.
There are many important factors to consider with biometric devices. One, which makes the use of these devices controversial, is security. Many people have objected to using biometric devices because the information captured is so sensitive. If it is not properly protected and people with bad intentions access it, a lot of damage can be done.
Accuracy is also important. This is an area, however, that can present challenges to the use of biometric devices. Many are designed to capture a person’s characteristics exactly as they are without the ability to allow for potential changes. If, for example, a facial recognition system is used and a person is involved in an accident that damages their face, serious problems can arise. It may be difficult or impossible to get the system to accept the change.
Capacity is another issue. Biometric devices are usually connected to some type of storage mechanism that stores the captured data. These usually have limitations. It is important to consider sufficient storage space when planning to use biometric devices. How long a person’s information is stored generally depends on the design of the system.
