What Are Biometrics?

Biometrics have been used in different areas of human security for years, and recently they have seen an explosive growth in their use. Previously biometics were used to track individuals in secure premises, but today biometics play a key role in implementing stronger security in businesses and public areas. Here’s a look at how biometics work and what biometric security systems are capable of.

The idea behind biometics is that it takes several small pieces of identifying information, including: a fingerprint or iris scan, hand geometry and facial appearance, and matches these bits of identifying information to a series of patterns known as “genetic fingerprints”. If the individual bears a matching set of genetic fingerprints, then they are said to possess a “biometric match” to the person searching them out. This can often be done with a quick scan of an identifying document, such as a passport or driver’s license. However, biometics systems are starting to make use of more complex biometric matching methods, such as fingerprint recognition.

While it’s been around for nearly as long as fingerprints have, biometrics aren’t something new to the field of security. Fingerprints have actually been used as a form of biometric security for decades. Originally, biometrics would be used in security situations in high-security jobs, such as prison and military applications. Security guards would wear special identification badges on their uniform, which would only allow them to “see” the faces of authorized individuals. In this way, guards could perform extra checks, such as those required by gun control, or searches of dangerous or suspicious activity.

But while it was popular for employers to implement such systems at their workplaces, it wasn’t until the late 1970s that biometric systems began showing up in more public settings. At first, they were implemented for security reasons in government buildings and banks. But as time went on, biometric systems began popping up in retail settings as well. Bookstores would implement fingerprint scanners to ensure that customers would pay for items with their credit cards.

Today, biometric systems are widely used, not only in government and financial facilities but also in stores, offices, hospitals and even on vehicles. Even when driving a vehicle, you can use a biometric scan of your fingerprint to prevent anyone from stealing your identity, or to make sure that the car is safe before you leave the house. If you’re using a public facility like a hospital, you’ll find that biometric systems are common.

There are several different types of biometrics. One of the most common is a fingerprint scanning system. While it can be used in many different settings, including safety and security, it’s most commonly found in department stores and other retail environments. These kinds of biometrics can prevent fraud and can catch shoplifters who try to steal wallets or purses.

Biometrics can also be used in medical environments. A finger scan will let doctors know whether or not a person has been administered drugs or other substances that can potentially harm them. It is even possible to scan an employee’s hand to keep track of how much time they’ve spent working on the computer. By using biometrics in these different applications, it makes good business sense to use them. However, as noted, biometrics aren’t always foolproof. The best biometrics for security are iris scans or fingerprint scans.

Iris scans look just like human eyes, allowing employers to determine quickly whether or not a person is telling the truth about their time spent at a job. Fingerprint scanners can catch shoplifters and prevent others from using a card or wallet to take advantage of a person. While biometrics are still fairly new for security measures, they have rapidly become more commonplace. When choosing a security system, always consider the options available and find the best system for your needs.
