Self-Sovereign Identity and Verifiable Credentials in Your Digital Wallet

Self-Sovereign Identity and Verifiable Credentials in Your Digital Wallet

Mary Lacity, Erran Carmel
This paper provides an overview of Self-Sovereign Identity (SSI), a decentralized approach for issuing, holding, and verifying digital credentials. Through an analysis of the technology's architecture and a case study of the UK's National Health Service (NHS), the authors explain SSI's business value, implementation, and potential risks for IT leaders.

Problem Current digital identity systems are centralized, meaning individuals lack control over their own credentials like licenses, diplomas, or work histories. This creates inefficiencies for businesses (e.g., slow employee onboarding), high costs associated with password management, and significant cybersecurity risks as centralized databases are prime targets for data breaches and identity theft.

Outcome - Self-Sovereign Identity (SSI) empowers individuals to possess and control their own digital proofs of credentials in a secure digital wallet on their smartphone.
- SSI can dramatically improve business efficiency by streamlining processes like employee onboarding, reducing a multi-day manual verification process to a few minutes, as seen in the NHS case study.
- The technology enhances privacy by enabling data minimization, allowing users to prove a specific attribute (e.g., being over 21) without revealing unnecessary personal information like their full date of birth or address.
- For organizations, SSI reduces cybersecurity risks and costs by eliminating centralized credential databases and the need for password resets.
- While promising, SSI is an emerging technology with risks including the need for widespread ecosystem adoption, the development of sustainable economic models, and ensuring robust cybersecurity for individual wallets.
