xPrufy

xPrufy is a mobile evidence capture app designed to support file integrity for photos, videos, and audio. Each capture is associated with cryptographic hashes and signed metadata, with optional blockchain and trusted timestamp records for independent time-related verification.

Built for investigators, legal professionals, journalists, and safety-conscious users, xPrufy stores evidence on-device by default and provides “Export with Proof” packages that can be reviewed independently outside the app.

With chain-of-custody metadata, reliability scoring, and tamper-detection checks, xPrufy helps teams document, preserve, and review digital evidence workflows.

xPrufy provides integrity aids and does not replace independent professional review where required.
