The AI Lab has made its Trust Identity Protocol (TIP) available through a browser extension and web app. It uses post-quantum digital signatures, content fingerprints and a decentralized ledger to record declared authorship and whether a digital work has changed; it does not verify whether the work is true.
The AI Lab has made its Trust Identity Protocol (TIP) publicly available, offering creators a way to attach a record of declared authorship and later changes to digital content using post-quantum signatures. The system is available through a browser extension and web app, according to the company; it records who claims to have made a work, but does not determine whether the content is accurate or truthful.
The AI Lab says TIP combines ML-DSA-65 digital signatures, SHAKE-256 content fingerprints and a decentralized ledger. The signature associates a work with its creator, while the fingerprint is used to identify the content and detect whether it has been altered. The ledger is intended to preserve a record of those details. The company describes the record as permanent, but the announcement does not provide independent technical testing or operational details about how the ledger is governed.
A TIP record also includes the creator’s own declaration about whether a work was made by a person, an AI system or both. That is a declaration, not an independent finding about how the content was produced. The protocol is aimed at journalists, authors, filmmakers and other creators, who could use a record to help readers or publishers check a work’s claimed origin and modification status.
The AI Lab founder and chairman, Dinesh Mendhe, invented TIP, while chief executive Dr. Sofia Martinez also promoted the service in the announcement. The company argues that creators should prepare for future risks to current digital signatures. Its estimate that the preparation window has shrunk from about 20 years to roughly two years is the company’s assessment, not a settled projection shared by all experts.
A Provenance Record, Not a Truth Test
TIP addresses a practical problem for online publishing: after a work is copied, edited or reposted, it can be difficult to establish where it came from and whether a particular file has changed. A signed, checkable record could give creators and publishers another way to document an original version and compare later copies against it. That may be relevant as AI-generated and altered material becomes more common, though the announcement does not establish how widely the protocol will be adopted.
The distinction between authorship and accuracy matters. A valid TIP record could show that a named account signed a particular content fingerprint and that the fingerprint matches the record. It would not, by itself, show that the signer is telling the truth about authorship, that a work’s claims are factual, or that its declared human or AI involvement is complete. Readers would still need other evidence to evaluate identity, context and accuracy.
Post-quantum cryptography is relevant because sufficiently capable quantum computers could threaten some cryptographic systems now used for digital trust. The AI Lab’s choice of a post-quantum signature scheme places TIP within a broader migration effort, but a protocol’s algorithm choice alone does not establish that the whole service is secure or that it will remain trustworthy over time.

The Push Toward Post-Quantum Signatures
Governments and technology companies have begun planning for a shift away from cryptographic methods considered vulnerable to future quantum computers. In August 2024, the U.S. National Institute of Standards and Technology published its first post-quantum standards, including FIPS 204, a standard for digital signatures. NIST draft transition guidance proposes phasing out some quantum-vulnerable algorithms after 2030 and disallowing them after 2035; that guidance is a proposal, not a final timetable.
The AI Lab’s announcement points to changing estimates of the resources a quantum computer might need to break RSA-2048. It cites a 2019 estimate of about 20 million qubits, a May 2025 estimate below one million, and a February 2026 design analysis placing the figure below 100,000 physical qubits under specific engineering assumptions. These figures depend on different assumptions and are not dates for when such a machine will exist.
The announcement also cites a 2025 Global Risk Institute report estimating a 28% to 49% likelihood that a cryptographically relevant quantum computer could arrive within 10 years. Google has set 2029 as its own post-quantum migration deadline, according to the source material. Such estimates and corporate schedules illustrate planning concerns; they do not confirm that the quantum threat will materialize on a particular date.
““Trust is no longer a default. It has to be signed.””
— Dr. Sofia Martinez, chief executive and president of The AI Lab
Testing, Governance and Adoption
The announcement does not provide independent security audits, test results, or a detailed account of how TIP handles corrections, disputed authorship, lost signing keys or changes to the service. It also does not explain the ledger’s operators, governance rules, costs, or how users can verify records if the company or its tools are unavailable. Those details would help assess the system’s reliability in routine use.
It remains unclear how widely publishers, platforms and other creators will adopt TIP, and whether records will be interoperable with other provenance systems. A protocol can help preserve a signed claim about a file, but cannot by itself establish that the signer is the actual creator or that the content is true. The AI Lab’s two-year estimate for quantum preparation is also its stated view; the supplied material does not establish a generally accepted countdown.
Availability and Independent Review
The AI Lab says people can use TIP now through its browser extension and web app. The next useful developments will be clearer documentation of the verification process, details about ledger governance and key recovery, and independent evaluations of the implementation. Adoption by newsrooms, publishing services and creator platforms would also indicate whether TIP becomes a practical part of content workflows.
For now, users and publishers considering the service will need to distinguish the record it creates from broader judgments about credibility. A TIP entry may help compare a file with a signed content fingerprint and display a creator’s declared identity and production method. Whether that record is accepted as meaningful evidence by other organizations, and how it performs as cryptographic standards and platforms change, remains to be seen.
Key Questions
What is the Trust Identity Protocol?
TIP is a content-provenance protocol from The AI Lab. The company says it uses digital signatures, content fingerprints and a decentralized ledger to record declared authorship and whether a work has changed.
Does TIP prove that content is true?
No. The protocol is described as recording authorship claims and modification status. It does not check whether a work’s statements are accurate.
What does a TIP record say about AI involvement?
The record includes the creator’s own declaration of whether the work was made by a person, AI or both. The announcement does not describe this as an independently verified finding.
Is a quantum computer expected to break digital signatures in two years?
That is not established. The roughly two-year preparation estimate is the view attributed to The AI Lab’s founder. The cited quantum timelines depend on technical assumptions and do not confirm when a capable machine will be available.
