Images Lose Metadata.
PixelSeal Doesn't.
PixelSeal embeds a cryptographically signed identity directly into image pixels — invisible, compression-resilient, and verifiable anywhere.
The Problem
The Internet Strips Context
Once your image leaves your platform, it loses its identity. PixelSeal restores persistence at the signal layer.
IPTC removed
Social platforms strip embedded text metadata on upload.
EXIF wiped
Camera data, GPS, and author fields deleted silently.
C2PA often stripped
Content Credentials not preserved across most pipelines.
Screenshots destroy metadata
Screen capture creates a new file with zero provenance.
Visible watermarks can be cropped
Overlay-based marks are removed in seconds with AI.
The Solution
Pixel-Level Identity
PixelSeal embeds a structured, signed payload into the DCT coefficients of your image — surviving every transform the internet throws at it.
Creator ID
8-byte SHA-256 hash of the creator's identity, embedded directly into pixel signal.
Asset ID
Content-derived fingerprint linking the signature to the original file bytes.
Timestamp
32-bit Unix timestamp proving when the signature was created.
HMAC Signature
Truncated HMAC-SHA256 tag — cryptographically proves the payload hasn't been tampered with.
Protected By
Reed–Solomon RS(45,28)
Corrects up to 8 byte-level errors
Redundant DCT Embedding
5× payload copies across mid-frequency coefficients
Alignment Recovery
Phase search + scaled-grid extraction for crop/resize survival
CRC-16 + HMAC-4
Dual integrity validation at payload level
Proven Resilience
Survival Matrix
Real results from PixelSeal's stress test suite. Zero embed changes needed.
| Transform | Survival |
|---|---|
| JPEG Q90 | Pass |
| JPEG Q80 | Pass |
| JPEG Q60 | Pass |
| Resize | Pass* |
| 5% Crop | Pass** |
* Alignment recovery mode required · ** Crop recovery with original-grid reconstruction
Trust Layer
Identity Needs a Registry
Without a registry, a pixel signature proves origin but cannot recover context. PixelSeal Registry provides the lookup layer that connects embedded identities to real-world profiles.
