  The Indian Personal Data Protection Bill 2019 provides a legal framework for
protecting personal data. It is modeled after the European Union's General Data
Protection Regulation(GDPR). We present a detailed description of the Bill, the
differences with GDPR, the challenges and limitations in implementing it. We
look at the technical aspects of the bill and suggest ways to address the
different clauses of the bill. We mostly explore cryptographic solutions for
implementing the bill. There are two broad outcomes of this study. Firstly, we
show that better technical understanding of privacy is important to clearly
define the clauses of the bill. Secondly, we also show how technical and legal
solutions can be used together to enforce the bill.
