The AI Lab says its Trust Identity Protocol (TIP) is now 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 digital work has changed. TIP does not verify the truth of a work’s claims, and the company’s estimate of roughly two years to prepare for quantum computing is its view, not a settled forecast.
The AI Lab has made its Trust Identity Protocol (TIP) publicly available, offering creators a way to sign digital works and record whether they have been altered. The system uses post-quantum cryptography and a decentralized ledger, but it records authorship declarations and content changes; it does not establish whether a work is accurate or truthful.
According to the company’s announcement, TIP is available through a browser extension and web app. A creator can attach a persistent tag to a digital work, sign it and record an attribution describing whether the work was made by a person, an AI system or both. The record is also intended to show whether the content has changed since it was signed.
The protocol uses ML-DSA-65 signatures, a cryptographic signature standard, and SHAKE-256 fingerprints to represent content. The company says those records are stored on a decentralized ledger. It presents TIP as a way for readers, publishers and other creators to check a work against its signed record, including when a story or other work is shared or cited.
The announcement does not provide independent testing results, adoption figures or details about the ledger’s governance. TIP’s records concern identity declarations and whether content matches a fingerprint. They do not certify that an attribution is accurate, settle ownership disputes or assess the truth of statements within the work.
Digital signatures can help establish that a file came from a particular signing key and has not changed since it was signed. For journalists, authors and filmmakers, that could provide a checkable record when work is copied, edited or reposted. It may also give newsrooms a way to compare a circulated item with an earlier signed version.
The potential relevance extends beyond routine copying. The AI Lab argues that future quantum computers could threaten some digital signature systems, while generative AI has made it easier to produce or alter convincing digital material. A signature scheme designed for post-quantum use is one response to that prospective risk. TIP’s practical value will depend on whether creators and publishers adopt it, whether records can be checked reliably, and how disputes over identity or permission are handled.
A TIP record should not be read as a general trust label. It can indicate that content matches a signed record and identify what a signer declared about its creation. It cannot, by itself, show that the signer is the rightful owner or that the content is genuine, lawful or factually correct.

Why the Quantum Deadline Is Debated
The AI Lab says advances in quantum computing and artificial intelligence have compressed the time available to prepare for a quantum threat, putting its estimate at roughly two years rather than about 20. That is the company’s assessment. The source material describes a range of estimates and milestones, not a consensus that a cryptographically relevant quantum computer will arrive on that schedule.
The announcement cites a Global Risk Institute 2025 report that assessed a 28% to 49% likelihood of a cryptographically relevant quantum computer within 10 years. It also points to Google’s stated 2029 target for moving to post-quantum cryptography and to NIST’s standards and draft transition guidance. NIST published its first post-quantum standards in August 2024; its draft guidance proposes phasing out some quantum-vulnerable algorithms after 2030 and disallowing them after 2035.
Those developments concern preparation and risk management, not proof that current digital signatures are already broken. The AI Lab’s case for TIP links that longer-term migration challenge with nearer-term concerns about altered and misattributed content.
““Trust is no longer a default. It has to be signed.””
— Dr. Sofia Martinez, CEO and president of The AI Lab

Adoption and Verification Questions
It is not yet clear how many creators or publishers will use TIP, how third parties will verify its records, or how the ledger will be maintained over time. The announcement does not describe procedures for correcting mistaken identity claims, resolving competing authorship claims or handling a creator who loses access to a signing key.
The strength of a content fingerprint also depends on what changes count as a new version and how the system handles edits, formats or excerpts. The source material does not specify how those cases are treated. Nor does it provide independent evaluations of the protocol’s security, performance or compatibility with publishing tools.
The quantum timeline remains uncertain. Research progress and migration targets inform planning, but they do not establish when a machine capable of breaking widely used cryptography will exist. TIP’s release likewise does not mean that it has been broadly adopted or that it can prove the truth of a work or conclusively settle ownership.

Testing TIP in Real Workflows
The immediate next step is for creators, newsrooms and other potential users to try the browser extension and web app and assess whether signed records fit their publishing and verification workflows. The AI Lab has announced public availability, but the source material gives no rollout schedule, adoption target or independent review date.
Readers can expect further information to matter most on verification methods, ledger governance, key recovery and how disputed claims are handled. Wider use would also depend on other services supporting TIP records. Separately, organizations will continue to face post-quantum migration decisions under standards and timelines set by bodies such as NIST; the timing of a capable quantum computer remains an open question.

Key Questions
What is TIP?
TIP is The AI Lab’s protocol for attaching a signed record to digital content. The company says the record identifies the creator’s declaration about who or what made the work and indicates whether the content has changed.
Does TIP prove that a story or image is true?
No. TIP is designed to record an attribution and detect changes relative to a signed fingerprint. It does not verify factual accuracy or establish that the person signing has a valid ownership claim.
What cryptography does TIP use?
The company says TIP uses ML-DSA-65 signatures and SHAKE-256 content fingerprints, with records kept on a decentralized ledger. The announcement does not include independent security test results.
Is a quantum computer expected to break current signatures in two years?
The roughly two-year preparation window is The AI Lab chairman’s estimate, not a confirmed forecast of when a machine capable of breaking current cryptography will be available. The source material cites a Global Risk Institute estimate for the chance of such a machine within 10 years and separate government and industry migration targets.
