Have you ever wondered how you can unlock your phone just by showing it your face? How just a simple scan can save the world or how common the use of biostatistics is in your everyday life? Opening your phone, scanning a QR code, signing into work with your fingerprint, or simply asking Alexa the date, are just some basic instances. How does it work though?
The biology of your body is the main and most important part of Biometrics. It is about your biological measurement or physical characteristics and how it can be used to identify or track an individual. The devices and technology you use daily authenticate and verify your body’s characteristics such as fingerprints, eye retinas and irises, voice patterns, facial patterns, and hand measurements.
Your fingerprints are unique and almost one of a kind, there is a 1 in 64 billion chance that you share the same marks and patterns on your fingertips as another person. Just by this, it is easy to recognize and then track someone just by their fingerprints. Ultrasonic sensors are the most accurate type of fingerprint sensor, and very difficult to fool with fake fingerprints.
Biometrics and fingerprint tracking is an essential part of crime fighting. In forensics, this pattern of ridges and furrows found on the human fingerprint is analyzed to determine who it belongs to by looking for patterns. Forensic scientists work in great detail and hygiene. Dusting for fingerprints and looking for strands of hair will help them track the person they need to. If you are wondering how they find the exact person they are looking for just by their thumbprint in movies and TV shows, it is because that person's prints were taken previously and placed in the database or an old criminal record.
In conclusion, biometrics and fingerprint tracking is not a complicated process, it is a simple observing, learning, and remembering process. So if you have ever wondered how Google Search knows what you want to search or how your face ID works with just a glimpse of your face, now you know that the new technology just learns our behavior and special patterns of our body. This is a rapidly evolving world for cybernetics and computer sciences and the possibilities are boundless!
