India unfortunately doesn’t have a privacy protection law as many democracies do. Digital technologies are double-edged swords. It is more likely that the design and use of data and digital technologies can potentially be intrusive and erode human rights.

Traditional police watch-towers and other surveillance methods had only a limited reach and were primarily based on immediate needs. But in an age when high-tech cubicles in police headquarters can replace the watch-towers and conventional intelligence gathering, a democracy can degenerate into a virtual surveillance society where surveillance gets universalised.

In India, the Chennai Police are at the forefront of this highly controversial venture. They have been using FACETAGR technology, which involves an AI-based face-recognition app that can be used in CCTV cameras as well as smartphones. Faces within a crowd can be compared in real time with facial features of criminals and other wanted persons available in the police database.
