Digi Yatra to expand to 15 more airports in India, says Siddharth Verma

Digi Yatra, an initiative co-ordinated by the civil aviation ministry to ensure seamless travel for passengers from the airport gates to boarding a flight, will be available in 15 more airports this fiscal, Siddharth Verma, head of IT operations at Digi Yatra Foundation, said. "All the metros are done and all the big airports are done. So now we are left with the smaller airports where the ministry evaluates if there is a need at all or not. Because at times you don't need such solutions if the volume is very low, or there is just one gate," he told Business Standard. Five of the new airports include Mangalore, Trivandrum, Srinagar, Chandigarh, and Nagpur. The rest are managed by the Airports Authority of India (AAI), whose infrastructure is ready but where technology integration is still under way. India has 24 of its major airports covered under Digi Yatra, covering nearly 90 per cent of outbound passenger traffic, Verma added. The upcoming airports in Navi Mumbai and Noida are not part of the 15, he clarified. Digi Yatra's technology, launched in 2022, has revolutionised travel across Indian airports through the implementation of self-sovereign identity or decentralised ID, which allows users to control their online information. Authentication is done through two documents: the Aadhaar and the boarding pass. To date, the app has been downloaded 14 million times and has facilitated more than 56 million journeys across Indian airports. 'It should be like a walk in the park, a kind of experience where nobody should ask for your documents. You just show your face and keep walking through the touchpoints seamlessly and don't have to exchange your documents with anyone.' The Digi Yatra app is linked with the UIDAI ecosystem. When a passenger downloads the app, fills in the required details — including the Aadhaar number — and receives an OTP to authenticate, UIDAI sends the Aadhaar details to the phone. 'Then your proof of presence is established by taking your selfie and matching it with the image on your Aadhaar. These two must match. We then create a verified credential (VC), which is like a digital photocopy with a digital stamp called proof value. This proof value, along with the ID document, is stored in the Digi Yatra wallet on the user's phone until it is deleted by the user.' Even with Aadhaar, Digi Yatra follows what Verma terms data minimisation. Only the passenger's name, gender, date of birth, and masked Aadhaar number are taken. 'Your address is not pulled because it is not required for this use case. Privacy by design means data minimisation must be embedded at the core.' The second step involves uploading the boarding pass. The technology pulls data from the QR code, including date of travel, name, seat number, PNR, origin, destination, and sequence number. 'When you link your boarding pass, we match the name linked earlier from your Aadhaar with the name on the boarding pass. If these match, along with the real-time facial image clicked at the airport, the gate opens. All this happens automatically. There is no human intervention,' Verma explains. Asked about data security concerns, he said data shared with the origin airport is deleted from Digi Yatra's biometric gallery within 24 hours of flight departure. 'The data becomes instantly obsolete. That's how the architecture is designed. Airports also cannot retain the data as per policy.' Digi Yatra also conducts annual audits at the enabled airports to ensure compliance with these policy guidelines and verify that systemic scripts are in place. 'Some airports delete it within four hours, some within five. Others delete it as per the policy required by the CISF and other security agencies.'
