OutDID

OutDID is a private identity verification service where users scan documents locally and a zero-knowledge algorithm produces a credential, so the business only receives a verdict. It serves platforms needing age or identity checks, addressing centralised verification that requires uploading original documents and leaves the platform holding storage duties and breach consequences. Verification requests open the app through a QR code or deep link, and the flow never passes through the business's servers.

Documents are parsed on device, with digests and issuer signatures checked locally, and a credential carrying only the required fields is produced while the original image never leaves the device; credentials can be reused across compatible sites without resubmitting documents. The service ships as an API supporting per-call and batch verification. Credentials carry an expiry and a minimum disclosure scope, must be regenerated afterwards, and the business keeps only the verdict and a timestamp.
