DECE-Graphic

DECE-Graphic Strengths

  • Allowed the UltraViolet DRM ecosystem to easily distinguish structural UI/cover graphic assets from actual encrypted video tracks in a Common File Format container
Limitations
  • Completely obsolete since the 2019 shutdown of UltraViolet
  • Unnecessary abstraction, as the underlying files were just standard JPEGs or PNGs
  • Causes modern strict MIME-type validators to fail if they rely on the Content-Type header
FACTI

FACTI Strengths

  • Provides undeniable, mathematically verifiable proof of a photo's origin (time, location, and device) via the StarkNet blockchain [1.3.1]
  • Privacy-first design utilizes zero-knowledge proofs (Groth16), meaning the actual image is never uploaded to a central server or blockchain
  • Invisible watermarking ensures that even if the image is screenshotted or cropped, tampering can be detected
Limitations
  • Lacks native rendering support in web browsers and standard image viewers, requiring specialized software to view
  • Requires blockchain registration at the moment of capture, making it incompatible with existing legacy photos
  • The proprietary nature of the container limits integration to environments supporting the BlockFact SDK
