In an increasingly inter-connected digital world, where social media apps have become the store-keeper of our lives, tracking not just our online behaviour but getting a peek into our daily lives, concerns around privacy is but natural. Vinit Goenka, a member of the governing council of CRIS (Centre for Railway Information System), and ex-member of the IT task force in the ministry of road and shipping, brings to fore the challenges and threats posed by lack of data privacy and control. In the book, Data Sovereignty: The Pursuit of Supremacy, Goenka, along with other co-authors, explains the pitfalls of data colonisation by social media and e-commerce giants. The book makes a case for strong laws to ensure control over the ownership of data, which today resides in servers beyond Indian shores. In an interaction with Outlook Business, Goenka explains why the fear over data is not mere paranoia, and why sovereignty over data is critical for India.
