• Abstract: 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.

  Web3's decentralised infrastructure has upended the standardised approach to digital identity protocols like OpenID Connect. Web2 and Web3 currently operate in silos, with selective disclosure web tokens (SD-JWTs) and Web3 dApps being reliant on verifiable-chain data. This paper explores the integration of Web3 within the OpenID Connect framework, scrutinising established authentication protocols for their adaptability to decentralised identities.

  Redactable signature schemes and sanitizable signature schemes are methods that permit modification of a given digital message and retain a valid signature. We propose implementing these protocols on a digital credential and compare them against other privacy-enhancing techniques to assess their suitability.

  Unsupervised person re-identification (ReID) aims to train a feature extractor for identity retrieval without exploiting identity labels. Due to the blind trust in imperfect clustering results, the learning is inevitably misled by unreliable pseudo labels. Confidence-Guided pseudo Label (CGL) enables samples to approach not only the originally assigned centroid but other centroids that are potentially embedded with their identity information.
