Abstract
This thesis examines how a decentralized approach based on Self-Sovereign Identity (SSI) and Distributed Ledger Technology (DLT) can strengthen trust in employment verification. Traditional CVs and document checks often depend on self-asserted claims and institution-bound processes, creating inefficiencies and trust gaps. By analyzing CV structures and related employment artifacts, the study identifies which elements can be transformed into Verifiable Credentials (VCs) and proposes a trust model that distinguishes between high-trust and low-trust issuers. Leveraging decentralized identifiers (DIDs), digital wallets, and cryptographic proofs, the system aims to partially automate hiring while enhancing privacy, authenticity, and cross-border interoperability. The work results in a scalable design for secure, user-controlled credential exchange across diverse employment contexts.
Dette speciale undersøger, hvordan en decentraliseret løsning baseret på Self-Sovereign Identity (SSI) og Distributed Ledger Technology (DLT) kan øge tilliden i ansættelsesverifikation. Traditionelle CV’er og dokumentkontroller bygger ofte på selvangivne oplysninger og institutionsbundne processer, som skaber ineffektivitet og tillidsmangler. Gennem analyse af CV-struktur og tilhørende ansættelsesartefakter identificeres de elementer, der kan gøres til verificerbare legitimationsoplysninger (VC’er), og der udvikles en tillidsmodel, der skelner mellem udstedere med høj og lav tillid. Med brug af decentrale identifikatorer (DID’er), digitale wallets og kryptografiske beviser sigter systemet mod delvis automatisering af rekruttering, samtidig med at privatliv, autenticitet og grænseoverskridende interoperabilitet styrkes. Arbejdet munder ud i et skalerbart design for sikker, brugerkontrolleret udveksling af legitimationsoplysninger på tværs af forskellige ansættelseskontekster.
