Abstract

A self-sovereign identity (SSI) system represents a paradigm shift in identity management by leveraging the decentralization inherent in blockchain technology. The fundamental characteristics of the SSI system are constrained by a set of guiding principles and system properties. While knowledgeable scholars and practitioners have proposed such principles and properties, they have not yet been standardized. The SSI community has agreed upon and adheres to the existing proposals when implementing the SSI system. Additionally, the SSI system is used to manage personally identifiable information (PII), and compliance with certain standards and regulations is required. We discovered that while the current proposals do correspond to some extent to those documents, they cannot be characterized as explicitly compliant. We evaluate several well-known standards and regulations as credible sources in this work and compare them to the definitions in current proposals in order to identify inconsistencies. Then, we propose a list of SSI system properties that could be used to improve the security and privacy of the SSI system by addressing the inconsistencies discovered. We assess its applicability in real-world scenarios and its appropriateness from an expert’s perspective. The proposed properties yield meaningful results that may resolve the inconsistencies.
