Proof of origin that survives beyond publication.

puit.is embeds a media-bound UID at or near the source, linking the asset to an external provenance record and a UID-derived public commitment so origin evidence can remain re-checkable after redistribution.

It is built for cultural heritage, institutional records, and high-consequence media workflows where origin must remain verifiable beyond one platform, one database, or one moment in time.

Measured where provenance usually breaks.

Provenance systems often work while files remain untouched. The real test begins when media is resized, compressed, reformatted, reposted, or moved across systems.

Current TRL6 evidence shows 99.55% baseline perfect UID recovery (12,276 of 12,331 images) and 98.5% UID recovery after documented manual WhatsApp transfer (985/1,000 baseline-perfect items), supported by negative-control testing.

These are measured robustness results under defined transformation and recompression conditions, not a claim of universal removal-proof watermarking.

Built for the gap between creation and verification.

Metadata can disappear. Hashes break when files change. Detection systems estimate likelihood, but they do not preserve a durable link to origin.

puit.is is designed for the part of the journey where provenance usually fails: after media leaves its original system but still needs to be trusted, challenged, reused, archived, or verified later.

That makes it relevant for digital heritage, public records, editorial workflows, rights management, brand protection, and any environment where evidence must survive beyond the first upload.

Core pillars

Source-first

Attach a durable link to provenance before the file starts moving.

Robust through transformation

Designed for compression, edits, migration, derivatives, reposting, and reuse.

Re-checkable across systems

Support re-checks across institutions, systems, and workflows without relying on one closed platform. Independently operated verification remains a planned validation path.

Privacy-by-design

Verify origin without exposing more information than necessary.

Where continuity matters

From archives and newsrooms to brands and evidence workflows, puit.is is designed for contexts where origin, continuity, and independent verification matter after files start moving.

Digital heritage preservation

Challenge

Digital collections move across systems, formats, and time. Once provenance weakens, authorship, rights, and institutional trust are harder to defend.

How puit.is helps

puit.is embeds a durable UID at or near digitisation, linking the asset to a provenance record so continuity stays checkable across derivatives, migration, and reuse.

Impact

Stronger continuity across migration and institutions.

Journalism and news media

Challenge

Newsroom assets are edited, published, syndicated, and reposted under deadline. Trust weakens the moment provenance breaks anywhere along the chain.

How puit.is helps

puit.is supports source-linked continuity through editorial workflows, syndication, and redistribution after publication.

Impact

More inspectable origin evidence across editorial and redistribution workflows.

Film and VFX

Challenge

Production assets pass through many hands, versions, and render steps. Once continuity weakens, attribution and leak tracing become harder to reconstruct.

How puit.is helps

puit.is adds source-linked provenance that stays meaningful across editing, rendering, versioning, and downstream reuse.

Impact

Stronger attribution across complex media pipelines.

Platforms and redistribution

Challenge

Social-platform redistribution can strip embedded metadata on upload, detaching files from their original context.

How puit.is helps

puit.is is designed to keep origin linkages meaningful after reposting, re-encoding, resizing, and ordinary transformation.

Impact

Durable provenance where metadata alone does not travel.

High-stakes documentation and evidence workflows

Challenge

When digital records may later face dispute, broken continuity creates risk. Evidence is harder to defend if origin cannot be checked after handling.

How puit.is helps

puit.is supports stronger provenance continuity across transfer, long-term storage, archiving, and later independent review.

Impact

Stronger auditability when records face later scrutiny.

See where provenance fits

If provenance breaks somewhere in your workflow, we would like to hear where it happens and what has to hold up later.

Roadmap to institutional readiness

puit.is is moving from robust image-layer provenance toward broader media formats, lighthouse pilots, and auditable deployment environments.

More formats

From images toward audio, video, 3D, and complex heritage objects.

Lighthouse pilots

Heritage, archive, newsroom, and public-interest workflows.

Verification layer

Confidence-graded checks with clearer evidence outputs for real review processes.

Independently operated nodes

Independently operated verification and multi-operator provenance are planned TRL7–8 validation and scale paths.

Make provenance operational.

Bring us a workflow where provenance breaks, and we will scope a bounded test around it.
