Introduction

Self Sovereign Identity (SSI)​

SSI is a set of principals and to some extent similar to GDPR regulation. When developing a solution the SSI principals fit well to describe what is attempted to be achieved in a decentralised solution without one company or government having all of the control

These are the principals of Self-Sovereign Identity originally published by Christopher Allen in 2016 in The Path to Self-Sovereign Identity.

  1. Existence
  2. Control
  3. Access
  4. Transparency
  5. Persistence
  6. Portability
  7. Interoperability
  8. Consent
  9. Minimalization
  10. Protection

Distributed Ledger Technology (DLT)​

To avoid lockin for a single solution provider (silo) and allow for interoperability between different actors in the personal data handling arena a distributed solution is required. A distributed ledger technology (DLT) based on blockchain allows establishing trust between actors and exchange of data. The exchange of data can be done securely and with zero knowledge proof. Zero knowledge proof limits private data shared by simply answering a claim. For example, I prove I am over 18 without revealing more personal information than is necessary like full date of birth. To test DLT refer to instructions in Aries play ground.
