What is Offline Aadhaar Verification?
Offline Aadhaar Verification is a recognised identity verification mechanism that enables individuals to generate and share a digitally signed Offline Aadhaar data file for verification purposes. The shared data contains limited identity attributes such as name, address, date of birth, gender, and photograph, and is intended solely for identity verification.How Offline Aadhaar Verification Works
Consent Capture
The individual is presented with a consent screen and explicitly agrees or declines to proceed with Offline Aadhaar Verification.
Voluntary Aadhaar Number Submission
The individual voluntarily provides their Aadhaar number to initiate the offline data sharing process.
OTP-Based Access to Offline Data
A one-time password (OTP) is sent to the mobile number registered with Aadhaar. Upon successful OTP validation by the Aadhaar holder, the individual accesses and downloads a digitally signed Offline Aadhaar data file.
Offline Data Verification
The Offline Aadhaar data file contains verified demographic information, including name, address, photograph, gender, and date of birth, which can be validated offline.
Optional Liveness and Face Match
Where required, the photograph contained in the Offline Aadhaar data file may be matched with a live photo or selfie captured in real time to perform face match and liveness checks. These checks are performed independently by the application and do not constitute Aadhaar authentication.
