The AI Lab says its Trust Identity Protocol (TIP) is publicly available through a browser extension and web app. It uses post-quantum digital signatures, content fingerprints and a decentralized ledger to record a creator’s identity and whether a work has changed; it does not establish whether the work is accurate or truthful.
The AI Lab has made its Trust Identity Protocol (TIP) publicly available, offering creators a way to attach a cryptographically signed record of who made a digital work and whether it has been altered. The company says TIP is designed to withstand future quantum-computing threats, but the protocol records provenance rather than verifying whether content is true.
According to The AI Lab’s announcement, TIP combines ML-DSA-65 digital signatures, SHAKE-256 content fingerprints and a decentralized ledger. A record, which the company calls a TIP, is intended to link a work to its creator, preserve the creator’s declaration of whether a person, AI or both produced it, and indicate whether the content has changed since it was registered. The company says the service is available through a browser extension and web app.
The AI Lab presents the protocol as a tool for journalists, authors, filmmakers and other creators seeking evidence of authorship and modification history. A newsroom or reader could use such a record to check a work’s claimed origin or compare it with a registered version before sharing or citing it. That is the company’s stated use case; the announcement does not show independent testing of TIP or establish how widely other services will support its records.
TIP’s limits are central to what it can establish. The AI Lab says the protocol does not determine whether a claim in a work is true. A signed record can associate content with an identity and reveal a mismatch with a recorded fingerprint, but it does not by itself prove that the named person created the underlying idea, that the creator’s declaration is accurate, or that the content is reliable.
A Provenance Record, Not a Truth Test
For creators and publishers, a durable record of authorship could help document when a particular digital work was registered and whether a later copy differs from it. That may be useful when content is reposted, altered or circulated under another name. In journalism, for example, a newsroom might use a provenance record as one piece of evidence when checking a file’s source or version history. It would not replace editorial verification, source checks or legal processes over ownership.
The post-quantum aspect addresses a longer-term concern: quantum computers powerful enough to break some widely used cryptographic systems could put existing digital signatures at risk. The AI Lab argues that preparation timelines are shrinking, citing changing estimates and migration plans. Those timelines remain estimates, not proof that a cryptographically relevant quantum computer is imminent. TIP’s release therefore offers a specific proposed response—signing content with a post-quantum algorithm—rather than evidence that the broader quantum threat has arrived.
The distinction matters for readers. A protocol can provide technical evidence that a record has not changed since it was signed, while leaving open whether the original was authentic, complete or honest. Provenance is not fact-checking, and the value of TIP will depend partly on whether creators, platforms and audiences adopt it and know how to interpret its records.

Why the Lab Cites Quantum Risk
The AI Lab’s release connects TIP to concerns about future attacks on digital signatures. The company cites a sequence of estimates: a 2019 estimate of about 20 million qubits to break RSA-2048, a May 2025 estimate of fewer than one million qubits from a Google Quantum AI researcher, and a February 2026 design study placing the requirement below 100,000 physical qubits under specific engineering assumptions. These figures refer to different work and assumptions; they do not amount to a settled prediction of when such a machine will exist.
The company also points to Google’s stated 2029 goal for moving to post-quantum cryptography and to standards work by the U.S. National Institute of Standards and Technology. NIST published its first post-quantum standards in August 2024, including FIPS 204 for digital signatures. The AI Lab says draft U.S. transition guidance proposes phasing out quantum-vulnerable algorithms after 2030 and disallowing them after 2035. These broader migration efforts provide context for TIP, but do not amount to an endorsement or assessment of the protocol itself.
The AI Lab’s headline estimate that preparation time has fallen from roughly 20 years to roughly two years is the company’s assessment. The announcement attributes the shorter horizon to progress in quantum hardware, error correction and AI-assisted research. It does not establish a consensus deadline for a machine capable of breaking current cryptography.

Adoption and Verification Questions
The announcement does not specify how the public ledger is governed, how creator identities are checked, what fees or usage limits apply, or how records can be corrected if a creator’s account is compromised or a declaration is disputed. It also provides no independent audit results, performance measurements or detailed comparison with other provenance systems. The exact process for checking TIP records outside the company’s own tools is not described.
It is also unclear whether major publishing, social media or distribution platforms will display or recognize TIP records. Without broader integration, creators may be able to register work while readers and institutions have limited ways to discover or interpret those records. The protocol’s cryptographic design and the company’s claims about quantum readiness have not been independently assessed in the material provided.
Finally, the source does not establish a firm date for a quantum computer capable of breaking current public-key cryptography. The estimates cited by The AI Lab and the broader migration deadlines are planning signals, not confirmation that such a machine will arrive within two years.

Platform Support and Independent Review
The AI Lab says TIP can be used now through its browser extension and web app. The next practical tests will be whether creators can register and retrieve records reliably, whether third parties can check them without relying on the company’s own presentation, and whether publishers or platforms incorporate the protocol into their workflows.
Readers and organizations evaluating TIP will also need more detail on identity checks, ledger governance, recovery from account compromise and dispute handling. Independent technical review could clarify the implementation’s security properties and the limits of its post-quantum claims. Until those details and adoption patterns are clearer, TIP should be understood as a newly released provenance tool, not a general guarantee of authenticity or truth.

Key Questions
What does TIP record?
The AI Lab says TIP records a creator’s identity, the creator’s declaration of whether a person, AI or both made the work, and whether the registered content has changed. It uses a digital signature, a SHAKE-256 fingerprint and a decentralized ledger.
Does TIP prove that content is true?
No. The AI Lab says TIP does not assess the truth of a work’s claims. It is intended to record provenance and changes, not to fact-check content.
Can people use TIP now?
The company says TIP is publicly available through a browser extension and web app. The announcement does not detail fees, eligibility or the extent of third-party platform support.
Is a quantum computer expected to break current signatures within two years?
That is The AI Lab’s estimate of the preparation window, not a confirmed forecast that such a computer will exist in two years. The quantum timelines cited in the announcement depend on differing assumptions and remain uncertain.
Has TIP been independently validated?
The source material does not report an independent security audit, performance evaluation or adoption by outside platforms. Those points remain open.
