What is Aadhaar Biometric?

Aadhaar biometric is the recorded data of a resident’s fingerprint, iris, or face that helps to identify him/her uniquely when used for identification purposes in India. Whether you’re signing up for a new government scheme or purchasing a service/product, biometric authentication has made identification much faster and more convenient than before.

Since this data is unique to you, it can be catastrophic in the wrong hands as an attacker or hacker might use it to carry out an unauthorized authentication. Therefore, keeping it safe by locking your Aadhaar biometrics is essential.

How Can Someone Misuse Your Aadhaar Biometric?

If a hacker has somehow managed to get your Aadhaar biometric data, he/she can use it to authenticate and gain unauthorized access to services you’ve linked or signed up for. This can even include your bank account or telecom services registered with your Aadhaar, risking your hard-earned savings. A recent incident on Twitter reported a cyber fraud where a hacker drained a resident’s bank account completely using Aadhaar biometrics from different places.

• Once locked, you can temporarily unlock it for ten minutes (or permanently) if you need the Aadhaar biometric for authentication.
