  Decentralised identifiers have become a standardised element of digital
identity architecture, with supra-national organisations such as the European
Union adopting them as a key component for a unified European digital identity
ledger. This paper delves into enhancing security and privacy features within
decentralised identifiers by integrating ring signatures as an alternative
verification method. This allows users to identify themselves through digital
signatures without revealing which public key they used. To this end, the study
proposed a novel decentralised identity method showcased in a decentralised
identifier-based architectural framework. Additionally, the investigation
assesses the repercussions of employing this new method in the verification
process, focusing specifically on privacy and security aspects. Although ring
signatures are an established asset of cryptographic protocols, this paper
seeks to leverage their capabilities in the evolving domain of digital
identities.
