The Cambridge dictionary defines biometrics as detailed information about someone’s body, such as patterns of color in their eyes, that can be used to prove who that person is. However, TechTerms defines biometrics as technology used to detect and recognize human physical characteristics. There are two categories of biometric identifiers which are Physiological characteristics that consists of fingerprint, face recognition, DNA, palm print, hand geometry, iris recognition, odor/scent, etc. and Behavioral characteristics which consists for voice recognition, gait recognition, etc. In recent years, it has become more and more popular for biometrics to be used as an authentication tool (e.g. mobile phone passwords using fingerprint scan, room entries using fingerprint or iris scan, etc.) because it is believed to be more reliable and genuine than the traditional recognition systems (e.g. phone passcodes, keys, tokens/tubs, etc.). This is mostly because every person has their unique biometric features that cannot be mimicked e.g. the ridges of a fingerprint is so unique that even dust or water on a person’s finger could change the way the ridges are read, the structure of the iris has its different structure is every individual person, Palm print is also varies from person to person with size or tiny features, facial recognition software’s are also a perfect example because facial structures differ from person to person hence why it is almost impossible for two people to look
