HashCam

What it does

AI can now generate extremely realistic photos, videos and voices. This creates a new problem: how can we prove what is real? HashCam seals photos, videos with tamper-proof cryptographic proof stored on the blockchain. Capture authentic media, verify files instantly, and generate proof certificates. In the AI era, the most valuable asset online will not be "content". It will be "verifiable proof".

HashCam helps individuals and businesses turn photos, videos, and documents into verifiable proof with blockchain-secured verification and shareable certificates.

Proof of authenticity. In every photo. In every video. HashCam seals your mediafrom hashcam.io
