During June 2025, Nat Sakimura developed privacy and security enhancements for the openid/OpenID4VP repository, focusing on verifiable credential exchanges. Sakimura designed and implemented privacy-by-design features such as user consent flows, privacy notices, purpose legitimacy checks, and selective disclosure, all documented in Markdown. The work reinforced security considerations for Verifier Attestation JWTs and Wallet invocation, aligning with enterprise risk reduction goals. Leveraging skills in privacy engineering, specification development, and technical writing, Sakimura improved the privacy posture of wallet-to-verifier flows. The depth of the contribution lay in integrating privacy controls directly into the OpenID4VP specification, supporting safer credential exchange.
