How puit.is keeps origin checkable after transformation
Puit.is combines imperceptible watermarking, tamper-evident public anchoring, and confidence-graded verification to preserve a checkable origin link across editing, compression, migration, reposting, and reuse.
Technology for provenance that has to survive real distribution.

Workflow overview
From creation to later review, puit.is is designed for provenance that can survive real distribution paths.
Embed at source
At or near the point of origin, an imperceptible signal is embedded into the file. It connects the media to a provenance claim without changing normal viewing or use.
Anchor the claim
A cryptographic commitment is linked to a tamper-evident public record, so later verification does not depend on one platform, vendor, archive system, or private database.
Verify later
The signal can be recovered and checked against the record. Results can be confidence-graded rather than purely binary, so verification remains useful after compression, reformatting, migration, reposting, or partial degradation.
Why now
Synthetic media is scaling faster than provenance infrastructure.
At the same time, archives, media institutions, regulators, and public platforms are increasingly required to preserve authenticity, attribution, and continuity across digital workflows.
Puit.is exists because origin is becoming operationally important again.
Core components
Three technical layers make provenance resilient, independently checkable, and practical to deploy.
Watermarking engine
Imperceptible, edit-tolerant embedding designed for distribution paths where metadata can be stripped and exact-file hashes no longer apply.
Public anchoring layer
Tamper-evident commitments keep provenance checkable across operators, institutions, systems, and time.
Verification toolset
Confidence-graded checks help reviewers understand how strongly a file still links back to its claimed origin after transformation.
Reproducible evidence
Runbooks, manifests, per-item results, and integrity hashes support independent re-checks and later review.
Vendor-neutral verification
Checks are designed to work beyond one closed platform, database, archive system, or operator.
Privacy-aware provenance
Origin can be verified without unnecessary exposure of sensitive data.
Designed for auditability, review, and regulatory alignment
Policy-aware architecture
Designed with European expectations for transparency, auditability, data protection, and digital trust in mind, including GDPR, the EU AI Act, eIDAS 2.0, NIS2, and the DSA.
Comparison with existing approaches
Puit.is does not ask whether media looks manipulated. It preserves the link needed to check where it came from.
Built to evolve without replacing the trust model
Puit.is is designed as a modular provenance stack. Watermarking, anchoring, verification, and deployment can improve as formats, attacks, and institutional workflows change - without rebuilding the entire system.
