Biometry, or Biometrics, the application of statistics to the study of living things.Biometry is especially useful in studying growth or biological similarities and differences. It is a vital part of insurance, public health, forestry, and many other fields.
Instead of using something you have (like a key) or something you know (like a password), biometrics uses who you are to identify you. Biometrics can use physical characteristics, like your face, fingerprints, irises or veins, or behavioral characteristics like your voice, handwriting or typing rhythm. Unlike keys and passwords, your personal traits are extremely difficult to lose or forget. They can also be very difficult to copy. For this reason, many people consider them to be safer and more secure than keys or passwords.
How fingerprinting works????
Fingerprinting has come a long way from the days when police officers lifted prints from a crime scene and checked them manually against their files. Modern fingerprinting techniques can not only check millions of criminal records simultaneously, but can also match faces, backgrounds and other identifiable characteristics to each perpetrator.
Biometrics vs. Forensics
Biometrics and forensics have a lot in common, but they’re not exactly the same. Biometrics uses your physical or behavioral characteristics to determine your identity or to confirm that you are who you claim to be. Forensics uses the same kind of information to establish facts in civil or criminal investigations.
