Four simple steps to cryptographically verify your content's integrity and authenticity.
Use the True Media mobile app to capture photos or videos. The moment you press the shutter, our app immediately generates a cryptographic hash of your content before any processing occurs.
Camera captures content
SHA-256 hash generated instantly
Your device automatically validates that the content came from our legitimate, unmodified app using iOS App Attest or Android SafetyNet. This proves the content wasn't generated by malicious software, AI or modified apps.
Device validates app authenticity
Proves content source legitimacy
The content hash and device attestation are submitted to the blockchain, creating an immutable, timestamped record. This provides cryptographic proof that your content existed at a specific time and hasn't been altered.
Hash submitted to blockchain
Creates immutable record
Anyone can verify your content by entering its SHA-256 hash into our verification portal. We'll compare the hash against blockchain records to confirm the content hasn't been modified since capture. You receive a certificate of authenticity.
