Blockchain is used in
biometric technology to keep personal data secure since only authorized access
is possible.
Biometric technology uses the
personal information of people. That's why keeping it secure is very
important. NEC India's Digi
Yatra, a biometric technology for authenticating passengers, makes use of
blockchain to protect the biometric data of passengers.
Digi Yatra has made it
possible for passengers to use biometrics like fingerprints, iris scans, or
faces to authenticate themselves at significant touchpoints at the airports.
The facility is based on consent provided by the passengers for using the
biometric details for the purpose of authentication.
Since the authorities are
responsible for protecting the sensitive data of passengers, they use
blockchain to protect the data. With the help of blockchain technology,
authorities ensure that only authorized access to the biometric details is possible.
Under the Digi Yatra
facility, the data of passengers are encrypted and not stored centrally. In
order to keep the data secure, the biometric details are shared only with the
airport of travel origin. To make sure that there is no breach, the data is
deleted from the system within 24 hours of departure of the flight.
The scheme was launched
initially in Delhi, Varanasi and Bengaluru. As of now, around 3.5 million
passengers have used the facility. Owing to the success, the facility was
extended to Vijayawada, Pune, Hyderabad, and Kolkata. Now, the facility is
about to be made available at the airports of Mumbai and Kochi.
Launching Digi Yatra required
the use of infrastructure that can be made available by an IT service provider.
IP-based cameras with edge processors are installed at various touch-points,
like boarding gates. They can help passengers avail the facility of touchless
boarding.
Digi Yatra has made the
flying experience less cumbersome for the passengers. The processes like
security screening get completed within a stipulated time, and they need not
wait in queues for a long time.
