India Trials Refined Full-Body Scanners At Two Airports
India is testing machines that can check passengers for hidden objects.
The tests are taking place at Bengaluru and Cochin airports.
Officials are collecting information about how often the machines raise alarms.
They will use this information to improve the machines’ computer programs.
The scanners are being designed not to show real pictures of people.
Instead, they will show a simple outline and mark only a suspicious area.
Officials are also checking whether Indian ornaments or mangal sutras cause unnecessary alarms.
Eight airports have been told to use these scanners, but Cochin is not one of those eight.
The final decision will come after the trials and algorithm improvements.
The Bureau of Civil Aviation Security is trialling full-body scanners at Bengaluru and Cochin airports.
Data on alarms and other trial results will guide decisions on deploying the scanners.
The scanners are being redesigned to show generic outlines rather than passenger images.
BCAS is refining algorithms to account for Indian clothing, ornaments and mangal sutras.
Full-body scanners have been mandated for eight airports, but Cochin is not among them.
- Who
- The Bureau of Civil Aviation Security, led on this issue by Director General Rajesh Nirwan.
- What
- Trials are being conducted to refine full-body scanners and their detection algorithms before wider deployment.
- Where
- Bengaluru and Cochin airports in India.
- When
- The trials were discussed on Thursday; the articles do not provide a calendar date.
- Why
- To address passenger-privacy concerns, reduce unnecessary alarms and adapt the technology to conditions common in India.
Privacy And Local Adaptation
Security And Wider Deployment
Passenger privacy
Privacy And Local Adaptation
Privacy concerns about displaying images of passengers have delayed deployment, so the scanners are being redesigned to show only generic outlines and suspicious areas.
Security And Wider Deployment
Security authorities are testing the scanners as a way to identify suspicious objects and are gathering alarm data before making deployment decisions.
Algorithm design
Privacy And Local Adaptation
Algorithms must be adapted to Indian passengers and account for ornaments and mangal sutras to avoid unnecessary alarms.
Security And Wider Deployment
Existing technology is based on foreign-market algorithms, and continued testing and refinement are being used to make the systems effective in Indian airports.
Key facts

Rajesh Nirwan
Director General of the Bureau of Civil Aviation Security
“What we are getting today in India is based on algorithms that have been designed for foreign markets. There are certain typical things that are on the body of Indian citizens or people living in India. So, those algorithms are also being continuously refined.”
