How to Use and Lock Your Aadhar Biometric Data Online

An Aadhar card number is a unique number issued to every Indian citizen. It is a centralized universal identification number that joins him directly to the verification procedures required throughout India and is mandatory for all the citizens. The Aadhar card is a small biometric data document that stores all the personal details of an individual including his address, date of birth, name, father’s name, etc.

These details are further stored in a government database and are becoming the government’s base for citizen services and public welfare works. Government has done various campaigns to publicize the importance of Aadhar card in an individual’s life. But still, there are various uses you won’t be aware of. We have highlighted those uses as follows.

Some Important uses of Aadhar Card

All-purpose identity card:

Aadhar card does not have a specific purpose just like a voter card that is only used to identify a voter. Instead, Aadhar card can be used for various identity purposes, making it a government-issued universally acceptable identity card. E.g. you can use it for address proof, date of birth proof, age proof, etc.

To avail subsidies

Another main use of Aadhar card is it makes you avail all the government subsidies an individual is eligible for. Since the government has all the required data on a particular individual, they only need their Aadhar card number as an identity proof to avail them various subsidies or programs issued by the government.

So far the government has introduced various schemes whereby it is mandatory for the individual to link their Aadhar card to a bank account and LPG connection so that they could receive their LPG subsidy directly into their bank accounts. This negates the possibility of cases of fraudulent claims in order to claim extra benefits from the government or the funds being misappropriated.

This also reduces the risk of misplacing of an original document, since the Aadhar can be downloaded onto any device and can be displayed at the required times.

Used for various government processes:

An Aadhar Card is the most essential document when it comes to verification, KYC, and identification purposes. Aadhar Card is used to speeding up the government and bureaucratic processes like:
• Acquisition of passport
• Opening a bank account
• Disbursing provident funds
• Taking benefits of government schemes like Jan Dhan Yojna
• LPG Subsidy Etc.

But have you ever wondered what it can be harmful to you? Means when you get an Aadhar card you give your important information including your fingerprint and retinal scan data to a government that is also called biometric data.

This biometric data is used for various identification purposes, e.g. when you submit an Aadhar card as an identity proof to get a SIM card, you use your fingerprint to allow the telecom company service provider to access your identity information. By doing this, you can quickly authenticate the Identity, speeding up the KYC verification process.

In the process, we forget that we have given a part of our personal information to the service provider. Several cases have been informed that claims the misuse of Aadhar biometric authentication data. The people who have claimed such cases have mentioned receiving an email from UIDAI stating that their data has been accessed via biometric authentication while they haven’t made use of their heir Aadhar card from longer duration. This is a quite shocking and alarming situation.
