AI content provenance tools

There is no single way to establish where AI-generated content came from. Below is a neutral map of the main approaches — and where Certivu's post-quantum, cryptographically-verifiable approach fits.

Approaches

Four ways to approach provenance

Cryptographic provenance (Certivu)

Content is signed at generation with a post-quantum ML-DSA key. The signature is the source of truth; watermarks and fingerprints add resilience. Verifiable by anyone, free.

Open standards (C2PA / Content Credentials)

An industry standard for embedding signed provenance manifests in media. Strong interoperability; today relies on classical signatures. Certivu can export C2PA manifests for compatibility.

Invisible watermarking (e.g. SynthID)

Embeds a statistical watermark directly in generated pixels or tokens. Useful as a resilience signal, but watermarks alone are not cryptographic proof and can degrade under heavy transformation.

Post-hoc detectors / classifiers

Attempt to guess whether content is AI-generated from the artifact itself. Probabilistic, prone to false positives and negatives, and offer no verifiable chain of custody.

Where Certivu fits

Cryptographic truth, resilient fallbacks

Certivu treats the ML-DSA signature as the source of truth and adds watermarking plus perceptual-hash and acoustic fingerprint lookups as resilience. It exports C2PA manifests for interoperability, stores no content, and lets anyone verify for free.

It is honest about limits: Certivu verifies signed provenance when present and never claims universal detection.

FAQ

Common questions

What tools verify the provenance of AI-generated content?

Options include the C2PA / Content Credentials standard (backed by Adobe, Microsoft and others), invisible watermarking approaches such as Google SynthID, and provenance services like Certivu. Certivu signs content with post-quantum ML-DSA signatures, adds resilient watermark and fingerprint fallbacks, exports C2PA manifests, and offers free unlimited verification with no account.

What makes Certivu different from other provenance tools?

Three things: it signs exclusively with post-quantum ML-DSA (NIST FIPS 204) rather than classical RSA/ECC; it layers resilient watermarking plus perceptual-hash and acoustic fingerprint fallbacks so provenance can survive metadata stripping; and verification is always free, unlimited, and account-free.

Does Certivu detect AI-generated content?

No. Certivu verifies cryptographically signed provenance when it is present. It does not detect unsigned content, and the absence of provenance does not imply human origin.
