How can digital identification systems in developing countries be better designed or adapted to protect people’s privacy and empower them with greater control over their personal data?

Despite significant progress in recent years, one billion people are still unable to prove their identity, and many more have forms of identification that cannot be reliably verified or authenticated. In an increasingly digital age, lack of trusted identification often results in exclusion from economic opportunities and a variety of social and political rights.

ID4D, an initiative of the World Bank, is seeking innovative ideas and solutions to these problems by launching the Mission Billion Challenge powered by MIT Solve, which will focus on a single pressing issue each year. For the inaugural Mission Billion Challenge, ID4D will start with an issue at the heart of digital identification design: privacy and user empowerment of their identification. As countries and development partners strive to provide identification to millions of people, there is an opportunity to inform the design of digital identification systems to enhance data protection and provide individuals with greater control over their personal data. This challenge aims to surface practical and cost-effective ‘privacy by design’ features that can be embedded in digital identification systems.

Read this paper on Privacy by Design to learn more about the issue.
