Authenticity workflow
Seal the source before screenshots strip the trail.
When metadata is lost through screenshots, reposts, compression, or cropping, ContentSeal falls back to proof receipts, visual fingerprints, OCR conflict checks, and a cautious trust card that helps ordinary people find the most credible source.
Seal Source
Create the accountable original before screenshots spread.
A proof receipt stores source hash, visual fingerprints, issuer claim, declared AI usage, lifecycle state, and official-source context. Recover scans compare against this receipt later.
What this creates
Exact SHA-256 proof for the original file.
Perceptual hashes for screenshots, crops, and reposts.
Human accountability fields for issuer and official source.
Lifecycle controls such as expiry, version, and deletion.
Trust guardrail
ContentSeal recovers source evidence and explains uncertainty. It does not claim a file is true, fake, or human-made purely from metadata or AI-classifier output.
