Shivangi Narayan is currently involved in a project studying digital policing in India, having recently submitted her PhD thesis titled ‘Policing and the construction of the criminal: A study of Bureaucracy and Algorithms in Delhi Police’ in Centre for Study of Social Systems (CSSS), Jawaharlal Nehru University (JNU), New Delhi. She is interested in all things tech, especially those related to big identification/data/predictive systems. Before becoming a researcher, Narayan was a Systems Analyst at an IT company in NCR and thereafter, a journalist at a fortnightly policy magazine. It was during her fieldwork as a journalist that she explored the ICT and data landscape of India and realised she needed to study it further. This book is her dissertation she wrote for her MPhil programme at CSSS, JNU.
