Best digital product passport AI tools

HashCam is a blockchain-based verification tool that provides tamper-proof authenticity proof for photos, videos, and digital products. By capturing media directly on the device with embedded GPS, metadata, and an immutable blockchain timestamp, it solves the trust deficit in the age of AI-generated content. It offers solutions for mobile (iOS), drone (DJI), and desktop (Mac) workflows, ensuring privacy by design without cloud uploads.
