Towards the classification of Self-Sovereign Identity properties

Self-Sovereign Identity (SSI) is a novel and emerging, decentralized identity approach that enables entities to fully control and manage their digital identifiers and associated identity data while enhances trust, privacy, security, and many other properties analyzed in this paper. The paper provides an overview of the SSI properties, focusing on an in-depth analysis, furthermore presenting a comprehensive collection of SSI properties that are important for the implementation of the SSI system. In addition, it explores the SSI process flow and highlights the steps in which individual properties are important. After the initial purification and classification phase, we then validated properties among experts in the field of decentralized and self-sovereign identity management using an online questionnaire, which resulted in a final set of classified and verified SSI properties. The results can be used for further work on the definition and standardization of the SSI field.
