Whitepaper - Self-Sovereign Identity

Self-Sovereign Identity (SSI) is a new concept for electronic identities that is based upon the blockchain technology. With the blockchain technology, a huge new research area appeared with lots of opportunities and potential. SSI combines the electronic identities with this promising technology.

In common identity management models, the user does not have control over her own identity data. For instance, revocation of identity data or their deletion might not be an easy task if even possible. Therefore, the idea of SSI is to give the citizen full control over her own data. This includes operations from updating or revoking attributes to fully deletion of the electronic identity.


The outcome of this project is a whitepaper with the focus on SSI. This whitepaper consists of three parts:
  1. The first part defines the concept of SSI and describes its underlying blockchain technology.
  2. In the second part, blockchain implementations are evaluated in order to find the most suitable to realize a SSI system. Evaluation criteria used for the evaluation were derived from the requirements of a SSI system.
  3. Finally, the last part identifies both the technical potential of a SSI system when using it as identity management system as well as some possible use cases.
