Unique Technology

Remote Manifests That Survive

Traditional embedded metadata gets stripped by social media platforms and CDNs. Our remote manifest technology stores authenticity proof externally, linked by content hash, so verification works no matter how the image is processed.

95%+

Survival rate after social media upload

100%

Survival after CDN optimization

90%+

Compression survival rate

<100ms

Verification lookup time

Embedded Only

Stripped by 90%+ of platforms

Remote Manifest

Survives any processing

Remote manifests use perceptual hashing to match images even after compression, resizing, and format conversion. The original proof is stored on our globally distributed infrastructure.
