Data security has become an important issue in the last few years. There were a lot of questions over the security
of Aadhaar data last year. Governments have a close watch on social media platforms such as Facebook and WhatsApp, whether they are misusing user data. In such a situation, people are also worried about the security of the data being collected for the population. According to the government, census data is completely secret. It cannot
be shared with any government or private agency. However, some information related to the National Population Register can be used by the government in investigation. Only the government can use the database of the final draft of the National Population Register.
