TL;DR: Decentralized identity moves verified credentials into user-controlled wallets, so people can prove attributes through selective disclosure rather than repeatedly handing over personal data, according to Daon; cryptographic signatures and revocation checks reduce breach exposure, fraud, and onboarding friction while aligning with emerging digital identity frameworks. The architectural shift matters because privacy gains only hold if issuers, wallets, and verifiers are governed as a trust ecosystem rather than isolated points.
Editorial analysis by NHI Mgmt Group, based on content published by Daon: “Decentralized Identity 101”.
Key questions
Q: How do organisations reduce identity data exposure when using verifiable credentials?
A: Use selective disclosure so the verifier receives only the attribute needed for the transaction, and avoid storing full identity evidence unless there is a clear business or regulatory need.
A: Security teams should design selective disclosure around the minimum attributes needed for each transaction, not around full credential reuse.
Q: How can organisations verify identity without centralising personal data?
A: Organisations can verify identity with decentralised credentials, signed claims, and issuer trust lists, so the verifier checks cryptographic proof rather than copying raw personal data into one central store.
Practitioner guidance
- Define the claims you will no longer centralise Inventory which identity attributes can be verified on demand instead of stored in your customer or workforce systems, then remove duplicate retention paths where possible.
- Separate issuer trust from verifier policy Document which issuers are trusted for which credentials, how verifiers check revocation, and what assurance level each transaction requires before deployment.
- Set wallet recovery rules before adoption Specify how users recover credentials, what device binding is required, and what happens when a wallet or private key is lost or suspected compromised.
Bottom line: Decentralized identity reduces identity sprawl by letting users present verified claims without sending full records to every service.

Decentralized identity is really a data minimisation architecture before it is an authentication model. The strongest security value comes from not collecting or reusing identity data everywhere in the first place. That changes the governance emphasis from storage control to disclosure control, which is a different design problem for identity programmes. Practitioners should evaluate where they can stop centralising identity evidence rather than only how they will protect it after collection.
A question worth separating out:
Q: What should identity teams do when a wallet device is lost or compromised?
A: They should revoke the wallet unit’s trust state and check whether any credentials bound to that hardware need to be invalidated. The point is to stop relying on a device once its integrity can no longer be assumed, rather than treating revocation as a generic afterthought.
