Aadhaar data security: Govt says UIDAI database remains breach-free; multi-layered systems protect 134 crore users

India’s Aadhaar database has not suffered any breach since its inception, the government told Parliament, underscoring that a multi-layered technology framework continues to safeguard the personal data of over 134 crore Aadhaar holders, ANI reported.

In a statement placed in the Lok Sabha, the Ministry of Electronics and Information Technology said the Unique Identification Authority of India (UIDAI) follows a “defence-in-depth” security architecture to protect citizens’ biometric and demographic information stored in the central database.

“Till date, no breach of Aadhaar card holders' data has occurred from the UIDAI database,” the ministry said in a press release issued on Wednesday, asserting that Aadhaar data remains fully secure.


Union Minister of State for Electronics and Information Technology Jitin Prasada submitted the details in Parliament on December 17, 2025, outlining the safeguards deployed to prevent unauthorised access and cyber threats.

According to the government, UIDAI uses advanced encryption technologies to secure data both during transmission and while at rest, ensuring that sensitive personal information remains protected at all times.

The Aadhaar ecosystem is supported by multiple layers of security controls, combined with continuous monitoring and periodic system audits to verify that protections remain effective. UIDAI also conducts regular security assessments to identify and address potential vulnerabilities.

Highlighting international validation of these systems, the ministry said UIDAI’s Information Security Management System is certified under ISO 27001:2022 by STQC. “UIDAI is also certified ISO/IEC 27701:2019 (Privacy Information Management System),” the release said.

Further, UIDAI has been declared a protected system, with the National Critical Information Infrastructure Protection Centre (NCIIPC) providing continuous cybersecurity advisories to strengthen its security posture, the government added.

In addition to internal safeguards, an independent agency periodically audits compliance with security protocols. These audits include Static Application Security Testing (SAST) and Dynamic Application Security Testing (DAST) to detect application-level risks.

Aadhaar remains the world’s largest biometric identity system, with about 134 crore active users. The platform has completed more than 16,000 crore authentication transactions, forming a critical backbone for delivery of government services and welfare schemes across the country, the ministry said.
