There are many types of biometric devices, but there are five types of biometrics security that are most commonly used. You can often see these special biometric devices in movies and TV shows, but you will find that these types of biometric security devices can be found in the most mundane places.
Biometrics is basically the recognition of human characteristics that are unique to each human, which can include facial recognition, fingerprints, voice recognition, retina scans, palm prints, and more.
Using this biometric technology to keep your devices safe is the best way to ensure that people stay out of your valuable possessions and information, and you will find that using any one of these five biometrics security devices is a great way to keep things safe:
Retina Scanner - These scan the unique biometric pattern in each person’s iris, and match it against a certain number of unique identifying marks that set every person apart from everyone else.
Iris scanning and retinal scanning are both used to identify a person according to their unique pattern, but they tend to be far costlier and more complex.
Finger Print Scanner - As far as price goes, the fingerprint scanning is on the lower end of the scale. The cheapest fingerprint scanners are the ones that only scan the actual print, though the costlier ones actually scan the presence of blood in the fingerprint, the size and shape of the thumb, and many other features. These costlier systems actually capture a 3D image of the fingerprint, thereby making it much more difficult for the fingerprint to be counterfeited.
Facial Biometrics - Each person around the world has a distinctly unique face, even two twins that the human eye cannot tell apart. It may be something as small as the slightly different placing of the eyebrows, the width of the eyes, or the breadth of the nose.
There are certain markers that enable these biometric recognition scanners to instantly identify the uniqueness of each person scanning their facial features, thus enabling the device to ensure that only the single person with the correct bone structure and feature placement can gain access.
Voice Recognition - Every person in the world has a unique voice pattern, even though the changes are slight and barely noticeable to the human ear. However, with special voice recognition software, those tiny differences in each person’s voice can be noted, tested, and authenticated to only allow access to the person that has the right tone, pitch, and volume of voice. It can be surprisingly effective at differentiating two people who have almost identical voice patterns.
Hand Print Patterns - When you place your hand on a scanner, you not only have a unique fingerprint pattern, but the size and shape of your entire hand is also very unique.
This includes the width and length of your palm, the width and length of your fingers, the distance between each knuckle, and the depth of each of the lines in your palm. This is more complex than regular fingerprint scanning, and will be much more accurate with less chance of falsification.
Some of these products will be far costlier than the others, as they feature technology that is much more complex. However, the amount that you spend on the various types of biometric devices will be directly proportionate to the level of security you need. The more secure you want your home or business to be, the more costly your device will be.
