The Aadhaar is a project of the Government of India and is the most ambitious program in the world aimed at issuing unique 12-digit numbers to every Indian as well as recording their biometrics for authentication services. A data leak would be potentially disastrous and would constitute a major breach of privacy as well. Such a leak can take place at the application level, the network level and the storage level. Data pertaining to the number of data breaches in the past decade has been analyzed to emphasize the importance of a secure ecosystem for such an ambitious project. A new methodology has also been studied which will help in heightening the security of the Aadhaar ecosystem and safeguarding the privacy of the people better. © 2020, Springer Nature Singapore Pte Ltd.
