The Core Idea: Privacy by Design
The DigiYatra system is built on a principle called 'self-sovereign identity'. In simple terms, this means you, the traveller, are in control of your own data. The Ministry of Civil Aviation has repeatedly stated that there is no centralised database
storing passengers' facial biometrics or personal information. Instead of creating a giant government-held pool of data, the system is designed to keep your most sensitive information on your own device. This decentralised approach is the cornerstone of its privacy and security framework.
What Data is Stored, and Where?
When you enrol in DigiYatra, you provide details like your name and Aadhaar information, and you take a selfie. This information, including a secure, encrypted version of your facial biometric, is stored only on your smartphone within the DigiYatra app's secure wallet. This data does not live on a government server or in the cloud. Think of your phone as the primary locker for your digital travel identity. The app creates a unique DigiYatra ID, which becomes your key for paperless travel.
The Data-Sharing Handshake at the Airport
Your data doesn't stay locked on your phone forever; it has to be used to verify your identity at the airport. When you have a flight, you upload your boarding pass to the app. The app then creates a temporary, encrypted travel credential that bundles your identity with your flight details. You then give consent to share this credential with the airport you are departing from. This data is sent only to that specific airport and is valid only for that single day of travel. It is not shared with airlines or any other third parties for marketing.
The 24-Hour Deletion Promise
This is the most critical part of the privacy policy. According to the DigiYatra Foundation, the data credential you share with the departure airport is purged from the airport's systems within 24 hours of your flight's departure. This means that after your journey is complete, the airport no longer holds the token that links your face to your boarding pass for that trip. This policy is designed to prevent the long-term storage of your travel patterns at airport servers. While this is the official policy, some reports, including a study by NITI Aayog, have called for clearer rules and audits on the deletion of all types of passenger information, not just facial biometrics.
Can You Delete Your Data Completely?
Yes. The control remains with you. If you decide you no longer want to use DigiYatra, you can permanently delete your account and data. The app provides a straightforward option to delete your profile. Once you initiate this, your credentials are removed from the system. This, combined with the voluntary, opt-in nature of the service, ensures that you can always go back to the traditional method of showing your ID and boarding pass at manual counters if you have any concerns.
So, Is It Secure?
DigiYatra uses end-to-end encryption for data transmission and stores the core biometric data on your personal device, which are strong security practices. The 'privacy by design' architecture is generally considered more secure than systems that rely on large, centralized databases. However, no digital system is entirely immune to risks. Civil liberties groups have raised valid concerns about the potential for metadata analysis and have called for greater transparency through regular, public audits to verify the system's claims. As of mid-2026, there have been no publicly disclosed breaches of biometric data from the DigiYatra system.
