Abstract
Digital credentials represent digital versions of physical credentials. They are the cornerstone of digital identity on the Internet. In order to enhance privacy, different authors implement selective disclosure in digital credentials, allowing users to disclose only the claims or attributes they want. This paper gives an overview of the most influential articles for selective disclosure, a chronology of the evolution of the methods, and a list of strategies and approaches to the problem. We identify the categories of approaches and their advantages and disadvantages. In addition, we recognize research gaps and open challenges and provide potential future directions.
