Fingerprints Aren’t As Unique As First Thought, But These 4 Special Characters Prove Nobody Is The Same
Fingerprints Aren’t As Unique As First Thought, But These 4 Special Characters Prove Nobody Is The Same
We like to think that we as individuals are unique. However, more often than not, it is difficult to determine just one thing that makes each of us different. There are currently a series of biometric techniques that can determine who an individual is with a high degree of accuracy. The following is a list of the four main ways used to determine a person’s identity.
1. Ears
Did you know that ears are one of the most unique elements of a person? In the last few years researchers have developed what is called an “image ray transform” which uses a sophisticated system to detect the shape of your ear. Using your ears for recognition is advantageous since they remain largely unchanged throughout a person’s life.They are also less intrusive than other forms of identification. This technology can identify a person’s ear with 99.6 percent accuracy which makes it one the most sophisticated systems out there.
2. Tongue
New developments in the identification of people have focused on the tongue. Researchers have built a sophisticated 3-D system that uses a laser to scan it. The tongue is an effective way to identify a person due to its unique shape and texture. The tongue is also the only internal organ which can be inspected without a high degree of intrusion.
3. Iris
The iris has been used widely to identify people. It is the structure in the eye that allows light in and controls the size of the pupil. Iris recognition uses a technique which is able to determine the intricate patterns within it. One of the advantages of this system is that the iris is internally protected and yet visible.
4. Gait
Did you know that a person’s walk can be one of the most determining factors in identifying someone? It’s true. The way someone walks has small variations. Just think about when someone walks while dragging their feet and slouching. There are roughly 24 different components that make up a person’s gait. Some technology can event determine the amount of light and shadows in a person’s clothing while they walk.
We all like to think that we are unique and that there is no one else quite like us. These tools used to identify people are accurate but there is still some degree of error. This is one of the reasons these tools are often used together to determine a person’s identity and reduce the risk of failure. We are unique but we are also very much alike.
