Abstract

Digital identity is the cornerstone of a digital economy. However, proving identity remotely is difficult to do. To complicate things further, identity is usually not a global, absolute construct, but the information shared with different parties differs, based on the relationship to the user. Therefore, a viable solution for digital identity should enable users to have full control over their personal information and share only the information that they wish to share with each service. Blockchain technology can help to realize a self-sovereign identity that puts the user in control of her information, by enabling a decentralized way to handle public key infrastructure. In the current contribution, we present the Sora identity system, which is a mobile app that utilizes blockchain technology to create a secure protocol for storing encrypted personal information, as well as sharing verifiable claims about personal information.
