Aadhaar Biometrics

For an Aadhaar user, UIDAI provides a mechanism to lock the biometric information and prevent any misuse. Biometric information refers to the iris, finger prints and facial photograph of which the fingerprint and iris data is to be used for authentication. In addition, Aadhaar stores the demographic information such as name, address, date of birth/age, gender, mobile number, email address.

One can actually protect privacy and confidentiality of one's biometrics data. Once the Biometric is locked, the Aadhaar holder will not be able to use their Biometrics (fingerprints/iris) for authentications and neither can anyone else, thus preventing potential misuse. The process has been kept simple and once locked, it will temporarily get unlocked for only ten minutes. It automatically gets locked again.
