What Are the Different Types to Verify Aadhaar?

The Aadhaar issued by the Unique Identification Authority of India (UIDAI) is a crucial document proving the identity of Indian citizens. Aadhaar verification is critical to facilitate security and block misuse across the spectrum of various services ranging from banking and telecommunications to government subsidization and online transactions. Organizations and service providers apply various verification techniques to verify Aadhaar information to ensure accuracy and regulatory compliance.

UIDAI has formulated stringent regulations to govern Aadhaar verification so that only the appropriate agencies can get access to and process Aadhaar information. With the growing usage of Aadhaar-based verification by industries, knowledge of various kinds of verification procedures is essential for businesses and consumers alike.

This blog explores the various Aadhaar verification methods, their applications, compliance requirements, and how they help maintain data security and integrity.

Different Forms of Aadhaar Documents

• Aadhaar Letter: A physical paper document released by UIDAI with the Aadhaar number, demographic information, and a QR code used for verification.
• e-Aadhaar: A digitally signed electronic version of Aadhaar, downloadable from the UIDAI website. It is password-protected and has legal validity under the IT Act, 2000.
• mAadhaar: A mobile app version of Aadhaar which enables users to have access to their Aadhaar information on their mobile phones. It has functionalities such as offline verification, locking/unlocking using biometrics, and sharing the QR code.
• Aadhaar PVC Card: A hard and portable plastic card form of Aadhaar with improved security aspects such as a hologram and digitally signed QR code. It may be purchased online using the UIDAI portal.

Types to Verify Aadhaar

Online Aadhaar Verification Methods

• OTP Verification: This is a common practice to verify aadhaar where a one-time password (OTP) is sent to the registered mobile number of the user for verification of identity.
• Demographic Authentication: This involves authentication of rudimentary personal details like name, date of birth, and address against the Aadhaar database.
• Biometric Authentication: It employs fingerprint or iris scans to compare a person’s identity with the information present in the UIDAI database.
• Virtual ID (VID) Verification: In place of Aadhaar number, a 16-digit virtual ID is generated and utilized for verification.

Offline Aadhaar Verification Mechanisms

• QR Code Authentication: The QR code in the Aadhaar card or e-Aadhaar can be scanned to verify the aadhaar of an individual.
• Aadhaar Paperless Offline e-KYC: An XML file containing crucial Aadhaar details can be downloaded and used for verification offline.
• e-Aadhaar Verification: A downloaded e-Aadhaar document can be displayed as identification evidence for verification.
• Physical Aadhaar Card Authentication: Physical Aadhaar PVC card can be produced to authenticate identity.

How Aadhaar Authentication Works?

The UIDAI offers Aadhaar-based authentication services on demand. As a first step, an authentication request is required to be made to the concerned authority. The authority cross-matches the information provided by the applicant with the information available in the CIDR (Central Identities Data Repository).

The authority can authenticate Aadhaar information by providing the Aadhaar number or through biometric information. In case the provided information is identical to the records, the answer is “Yes”; else it is “No.”

Types of Authentication

• Demographic Authentication: While enrolling in Aadhaar, people give their personal information like name, date of birth, address, and gender. These are called demographic information. When such information is verified by the CIDR with the information provided by the individual, it becomes Demographic Authentication.
• Biometric Authentication: This is accomplished by matching the biometric data (e.g., fingerprints or iris scans) captured at the time of Aadhaar authentication with the data provided by the individual. There are two types of biometric verification processes.
• Multi-Factor Authentication: The UIDAI also allows agencies to combine multiple authentication methods based on their requirements. This approach is referred to as multi-factor authentication.
• OTP-Based Aadhaar Authentication: Another option is to verify individuals using an OTP sent to their Aadhaar-registered mobile number. 

Data Privacy Regulations

• Aadhaar verification is regulated by the Aadhaar (Targeted Delivery of Financial and Other Subsidies, Benefits and Services) Act, 2016 (Aadhaar Act).
• The Personal Data Protection Bill (PDPB) (now transforming into the Digital Personal Data Protection Act, 2023) places regulations on managing Aadhaar-connected personal data.
• UIDAI (Unique Identification Authority of India) enforces data security standards to prevent misuse and unauthorized access.
• Consent-based authentication is mandatory for Aadhaar verification, ensuring individuals have control over their data.
• Organizations handling Aadhaar data must follow data minimization, storage limitation, and purpose limitation principles.

Compliance Guidelines

• KYC (Know Your Customer) Compliance: Aadhaar e-KYC is allowed for regulated institutions such as banks, telecom companies, and NBFCs under the guidelines of UIDAI.
• Aadhaar Authentication Regulations, 2016: Details the process and security requirements for authentication service providers.
• Offline Aadhaar Verification: Companies can perform Aadhaar XML, QR code, or masked Aadhaar verification without storing sensitive data.
• Data Security Measures: All Aadhaar data processing will be protected by encryption, tokenization, and access controls.
• Penalties for Non-Conformity: Non-compliance with the Aadhaar laws shall result in penalty, cancellation of licenses, and any legal process established under the Aadhaar Act and IT Act, 2000.

Benefit of Aadhaar Verification

• Fraud Control: Aadhaar verification protects identity fraud and financial crime by ensuring that only genuine people can avail themselves of convenient services. Biometric and OTP-based verifications prevent fraudsters from misusing the personal information of a person.
• Improving Customer Experience: Aadhaar eKYC enables easier identification verification, eliminating paperwork and delay. Customers onboard in a matter of minutes, with ease and hassle-free transactions.
• Simplification of Services: Aadhaar enables the most rapid and efficient delivery of service in domains ranging from banking to telecommunication services to government schemes. Minimizes redundancies, enhances accuracy, and keeps benefits in front of the intended individuals.
