Your Aadhaar

Aadhaar number is a 12-digit random number issued by the UIDAI (“Authority”) to the residents of India after satisfying the verification process laid down by the Authority. Any individual, irrespective of age and gender, who is a resident of India, may voluntarily enrol to obtain an Aadhaar number. A person willing to enrol has to provide minimal demographic and biometric information during the enrolment process which is totally free of cost. An individual needs to enrol for Aadhaar only once and after de-duplication only one Aadhaar shall be generated, as the uniqueness is achieved through the process of demographic and biometric de-duplication. Aadhaar number is verifiable in an online, cost-effective way. It is unique and robust enough to eliminate duplicates and fake identities and may be used as a basis/primary identifier to roll out several Government welfare schemes and programmes for effective service delivery thereby promoting transparency and good governance. This is the only program of its kind globally, wherein a state-of-the-art digital and online ID is being provided free of cost at such a large scale to people, and has the potential to change the way service delivery functions in the country. Aadhaar number is devoid of any intelligence and does not profile people based on caste, religion, income, health and geography. The Aadhaar number is a proof of identity, however, it does not confer any right of citizenship or domicile in respect of an Aadhaar number holder. Aadhaar is a strategic policy tool for social and financial inclusion, public sector delivery reforms, managing fiscal budgets, increasing convenience and promoting hassle-free people-centric governance. Aadhaar can be used as a permanent Financial Address and facilitates financial inclusion of the underprivileged and weaker sections of the society and is therefore a tool of distributive justice and equality. The Aadhaar identity platform is one of the key pillars of the ‘Digital India’, wherein every resident of the country is provided with a unique identity. The Aadhaar programme has already achieved several milestones and is by far the largest biometrics based identification system in the world. Aadhaar identity platform with its inherent features of Uniqueness, Authentication, Financial Address and e-KYC, enables the Government of India to directly reach residents of the country in delivery of various subsidies, benefits and services by using the resident’s Aadhaar number only..

Aadhaar verification/authentication is governed by the sections of Aadhaar Act, 2016, under which the use case has been notified by the concerned Ministry/Department for providing services.

There are many agencies that simply accept physical copy of Aadhaar and do not carry out any biometric or OTP authentication or verification. Is this a good practice?

No, in this connection MeitY has issued detailed instructions to all Government Ministries/Departments vide office memorandum no 10(22)/2017-EG-II(VOL-1) dated 19.06.2023 .

If Aadhaar has to be freely used for proving identity and it is safe to do so, then why has UIDAI advised people not to put up their Aadhaar number in Social Media or public domain?

You use PAN card, debit card, credit card, bank cheques wherever required. But do you put these details openly on internet and social media such as Facebook, Twitter, etc.? Obviously no! You do not put such personal details unnecessarily in public domain so that there is no unwarranted invasion attempt on your privacy. The same logic needs to be applied in case of uses of Aadhaar.

Recently, UIDAI has issued an advisory asking people not to share their Aadhaar number openly in the public domain especially on Social Media or other public platforms. Does this mean that I should not use Aadhaar freely?

You should use your Aadhaar without any hesitation for proving your identity and doing transactions, just like you use your bank account number, PAN card, debit card, credit card, etc., wherever required. What UIDAI has advised is that Aadhaar card should be freely used for proving identity and doing transactions, but should not be put on public platforms like Twitter, Facebook, etc. People give their debit card or credit card details or cheque (which has bank account number) when they purchase goods, or pay school fee, water, electricity, telephone and other utility bills, etc. Similarly, you can freely use your Aadhaar to establish your identity as and when required without any fear. While using Aadhaar, you should do the same level of due diligence as you do in case of other ID cards – not more, not less.

One Aadhaar: Aadhaar is a unique number, and no Aadhaar number holder can have a duplicate number since it is linked to their individual biometrics; thereby identifying fake and ghost identities which result in leakages today. Savings from eliminating duplicates and fakes through Aadhaar-based identification will further enable governments to expand benefits to other eligible individual s. Portability: Aadhaar is a universal number, and agencies and services can contact the central Unique Identification database from anywhere in the country to authenticate a beneficiary's identity by availing authentication services. Electronic benefit transfers: The UID-enabled-Bank-Account network will offer a secure and low cost platform to directly remit benefits to Aadhaar number holders without the heavy costs associated today with benefit distribution; the leakages in the current system will also be stemmed as a result. Aadhaar-based authentication to confirm entitlement delivered to the beneficiary: The UIDAI will offer online authentication services for agencies who wish to validate a A adhaar number holder 's identity; this service will enable confirmation of the entitlement actually reaching the intended beneficiary. Improved services through increased transparency: Clear accountability and transparent monitoring would significantly improve access and quality of entitlements to beneficiaries and the agency alike. Self-service puts A adhaar number holders in control : Using Aadhaar as an authentication mechanism, A adhaar number holder s should be able to access up-to-date information about their entitlements, demand services and redress their grievances directly from their mobile phone, kiosks or other means. In the case of self-service on the A adhaar number holder 's mobile, security is assured using two-factor authentication (i.e. by proving possession of the A adhaar number holder 's registered Mobile Number and knowledge of the A adhaar number holder 's Aadhaar PIN). These standards are compliant with the Reserve Bank of India's approved standards for Mobile Banking and Payments.

How does the UIDAI protect the individual and their information?

Protection of the individual, and the safeguarding their information is inherent in the design of the UID project. From having a random number which does not reveal anything about the individual to other features listed below, the UID project keeps the interest of the individual at the core of its purpose and objectives. Collecting limited information Data collected by the UIDAI is purely to issue Aadhaar numbers, and confirm the identity of Aadhaar number holders. The UIDAI is collecting basic data fields in order to be able to establish identity– this includes Name, Date of Birth, Gender, Address, Parent/ Guardian’s name essential for children but not for others, mobile number and email id is optional as well . The UIDAI is collecting biometric information to establish uniqueness – therefore collecting photo, 10 finger prints and iris. No profiling and tracking information collected The UIDAI policy bars it from collecting sensitive personal information such as religion, caste, community, class, ethnicity, income and health. The profiling of individuals is therefore not possible through the UID system, since the data collected is limited to that required for identification and identity confirmation. The UIDAI had in fact, dropped the ‘place of birth’ data field – part of the initial list of information it planned to collect – based on feedback from CSOs that it could lead to profiling. The UIDAI also does not collect any transaction records of the individual. The records of an individual confirming their identity through Aadhaar will only reflect that such a confirmation happened. This limited information will be retained for a short period time in the interest of the individual, to resolve any disputes. Release of information – yes or no response The UIDAI is barred from revealing personal information in the Aadhaar database – the only response permitted are a ‘yes’ or ‘no’ to requests to verify an identity. The only exceptions are the order of a court, or the order of a joint secretary, in case of national security. This is a reasonable exception and is clear and precise. This approach is also in line with security norms followed in US and Europe on access to data in case of a security threat. Data protection and privacy The UIDAI has the obligation to ensure the security and confidentiality of the data collected. The data will be collected on software provided by the UIDAI and encrypted to prevent leaks in transit. Trained and certified enrollers will collect the information, which will not have access to the data being collected. The UIDAI has a comprehensive security policy to ensure the safety and integrity of its data. It will publish more details on this, including the Information Security Plan and Policies for the CIDR and mechanisms for auditing the compliance of the UIDAI and its contracting agencies. In addition, there will be strict security and storage protocols in place. Penalties for any security violation will be severe, and include penalties for disclosing identity information. There will also be penal consequences for unauthorised access to CIDR – including hacking, and penalties for tampering with data in the CIDR. Convergence and linking of UIDAI information to other databases The UID database is not linked to any other databases, or to information held in other databases. Its only purpose will be to verify a person’s identity at the point of receiving a service, and that too with the consent of the aadhaar number holder. The UID database will be guarded both physically and electronically by a few select individuals with high clearance. It will not be available even for many members of the UID staff and will be secured with the best encryption, and in a highly secure data vault. All access details will be properly logged.

The UIDAI is collecting basic data fields in order to be able to establish identity– this includes Name, Date of Birth, Gender, Address, Parent/ Guardian’s name essential for children but not for others, mobile number and email id is optional as well . The UIDAI is collecting biometric information to establish uniqueness – therefore collecting photo, 10 finger prints and iris. No profiling and tracking information collected The UIDAI policy bars it from collecting sensitive personal information such as religion, caste, community, class, ethnicity, income and health. The profiling of individuals is therefore not possible through the UID system, since the data collected is limited to that required for identification and identity confirmation. The UIDAI had in fact, dropped the ‘place of birth’ data field – part of the initial list of information it planned to collect – based on feedback from CSOs that it could lead to profiling. The UIDAI also does not collect any transaction records of the individual. The records of an individual confirming their identity through Aadhaar will only reflect that such a confirmation happened. This limited information will be retained for a short period time in the interest of the individual, to resolve any disputes. Release of information – yes or no response The UIDAI is barred from revealing personal information in the Aadhaar database – the only response permitted are a ‘yes’ or ‘no’ to requests to verify an identity. The only exceptions are the order of a court, or the order of a joint secretary, in case of national security. This is a reasonable exception and is clear and precise. This approach is also in line with security norms followed in US and Europe on access to data in case of a security threat. Data protection and privacy The UIDAI has the obligation to ensure the security and confidentiality of the data collected. The data will be collected on software provided by the UIDAI and encrypted to prevent leaks in transit. Trained and certified enrollers will collect the information, which will not have access to the data being collected. The UIDAI has a comprehensive security policy to ensure the safety and integrity of its data. It will publish more details on this, including the Information Security Plan and Policies for the CIDR and mechanisms for auditing the compliance of the UIDAI and its contracting agencies. In addition, there will be strict security and storage protocols in place. Penalties for any security violation will be severe, and include penalties for disclosing identity information. There will also be penal consequences for unauthorised access to CIDR – including hacking, and penalties for tampering with data in the CIDR. Convergence and linking of UIDAI information to other databases The UID database is not linked to any other databases, or to information held in other databases. Its only purpose will be to verify a person’s identity at the point of receiving a service, and that too with the consent of the aadhaar number holder. The UID database will be guarded both physically and electronically by a few select individuals with high clearance. It will not be available even for many members of the UID staff and will be secured with the best encryption, and in a highly secure data vault. All access details will be properly logged.
