In 2009, India embarked on a scheme for the biometric identification of its people. The idea behind the project was to use digital technology—and the data collection it enables—for economic ends. But to register the entire Indian population, the state had to be persuaded to be involved in the project, later named “Aadhaar”. What have been the implications of this programme, in terms of privacy in particular? How has the population reacted and are the data protected? Interview with Christophe Jaffrelot and Nicolas Belorgey, authors of the 251st Etude du CERI entitled, L’identification biométrique de 1,3 milliard d’Indiens. Milieux d’affaires, Etat et société civile recently translated. The study is available in English under the title Identifying 1.3 Billion Indians Biometrically. Corporate World, State, and Civil Society (Heidelberg Papers in South Asian and Comparative Studies No. 80). Interview with the two authors by Corinne Deloy.
