How to Secure your Aadhar Data

What is Aadhar about?

India is turning in to a digitally enabled country and the role of Aadhar(unique identification number) can be considered as pivotal. Though it took some time to gain momentum, Aadhar has started rolling along with speed and we keep on seeing large number of government and private services being linked to Aadhar. The latest in the list of services which was linked recently was PAN card details. Going forward, it will be mandatory to link phone number to your Aadhar number.

Aadhar is a 12 digit unique identification number which identifies an individual. Aadhar details currently contain lots of personal data including address, date of birth, phone number, biometric data etc. This data is used to provide various services while authenticating the identity via backend data servers. So naturally it is of prime importance that Aadhar data stays secure. If it falls in wrong hands, it could be misused resulting in unwanted losses and unpleasant events.
