ABHA Labआभा
Anonymity for Bharat
We study how personal data leaks from the systems the world runs on, such as transport and mobility records, phones and wireless devices, health data and payments, with a specific focus on India. We build protections that hold up when someone actually tries to break them.
A research group in the Department of Computer Science and Engineering, IIT Jammu.

We focus exclusively on top-tier venues: A/A* conferences and Q1 journals.
What we work on
Four themes, one method: attack real systems and data releases, then build defences against what worked.
Mobility and location data
Re-identifying people in released trajectory and origin–destination data, and building anonymisation that scales to millions of users.
Read more →Wireless tracking
How Wi-Fi, Bluetooth and LoRaWAN devices give away identity and location, and how people can detect trackers aimed at them.
Read more →Anonymisation that holds up
Testing whether privacy claims survive real attacks, and turning the results into guidance for data publishers and regulators.
Read more →Health data
Quantifying privacy leakages and eventually protecting large-scale health-related data.
