Enhancing Airport Travel with DigiYatra: Secure and Seamless Identity Solutions

Tech Today’s Aayush Ailwadi interviews Suresh Khadakbhavi, CEO of DigiYatra foundation. The discussion centers on Digi Yatra's approach to ensuring user data privacy and security. Enrollment involves mobile number verification and OTP for authentication. Facial data, obtained from a trusted source like Aadhaar, includes name and digital image. Digi Yatra's biometric matching algorithm verifies identity using Aadhaar details, face, name, and gender, storing only the selfie in users' digital wallets while discarding Aadhaar data. Data is not stored centrally; instead, a self-sovereign identity model ensures no personally identifiable information is on distributed ledgers. Each credential is secured with a unique signature, a data string, and a hash value stored locally on users' phones. When traveling, users upload their boarding passes for name matching, and only the face data is sent securely to the airport's backend system. This streamlined process enhances security and privacy, allowing for advance data sharing while maintaining user control over their personal information.
