Biometric data in State hubs destroyed

Why in News?

A statement was made in the Supreme Court , that all biometrics stored in State Resident Data Hubs have been “destroyed” since  Aadhaar Act of 2016 does not allow biometrics to be stored with State-level authorities as a precaution against leakages.




The SC is hearing the question of the validity of Aadhaar, in the light of the recent landmark judgement, making a Right to Privacy a Fundamental Right under Article 21 of the Constitution.

The Aadhaar project was initiated in 2009 to address the issues related to leakage of benefits, subsidies, forgery and duplication of identity proofs etc.   It was envisaged as a biometric-based unique identity number that could help identify eligible persons.

In 2016, Parliament enacted the Aadhaar (Targeted Delivery of Financial and Other Subsidies, Benefits and Services) Act, 2016 to provide legislative backing to the project.  This Act allowed Aadhaar to be used for authentication purposes by the central and state government, as well as by private bodies and persons.

Protection of Information Collected Under Aadhaar

The Biometric and Demographic information collected under Aadhaar is submitted to the Unique Identification Authority of India (UIDAI) .

The Aadhar Number , Demographic and Biometric data are together stored in the Central Identities Data Repository (CIDR)


The Unique Identification Authority of India (UIDAI) is a statutory authority established under the provisions of the Aadhaar (Targeted Delivery of Financial and Other Subsidies, Benefits and Services) Act, 2016 (“Aadhaar Act 2016”) under  Ministry of Electronics and Information Technology (MeitY).

It is responsible for Aadhaar enrolment and authentication, including operation and management of all stages of Aadhaar life cycle, developing the policy, procedure and system for issuing Aadhaar numbers to individuals and perform authentication and also required to ensure the security of identity information and authentication records of individuals.


Central Identities Data Repository (CIDR) is a government agency that stores and manages data for the country’s Aadhaar project. CIDR, which is regulated by the Unique Identification Authority of India (UIDAI), is responsible for verifying the authenticity of documents submitted by an individual and that an applicant is actually the person he or she claims to be.
