Biometrics are biological measurements — or physical characteristics — that can be used to identify individuals.
- It can involve physiological sources (fingerprints, iris, facial, vein, DNA) and behavioural sources (gait, voice, typing rhythm).
- It helps to accurately identify an individual based on biology and behaviour.
- Biometric scanners are hardware used to capture biometrics for the verification of identity.
- Biometrics is easy to use, so there is no fear of being misplaced at home when personal identification is needed. Biometrics cannot be easily stolen like an identity card or key.
Challenges of biometrics
- Stealing or leaking of biometric data cannot be resolved and has lifelong challenges. Unauthorised usage of biometric data can exist and create law and order issues like impersonation.
- Biometric inaccuracy can result in false positive or false negative permissions, resulting in unauthorised usage.
- Chances of spoofing of biometric data using high-end technology exist. Without human verification, it can be a true challenge.
- Effective implementation of the scheme involves a very high cost as well as recurring expenses to maintain the database.
- Inclusivity challenges can arise for persons with physical disabilities.
