The AI Lab says its Trust Identity Protocol is now publicly available through a browser extension and web app. TIP 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 assess whether content is true.
The AI Lab says it has made its Trust Identity Protocol (TIP) publicly available, offering creators a way to attach a signed record of authorship and later changes to digital works. The company says the protocol uses post-quantum cryptography and can be used through a browser extension and web app, as concerns grow about AI-generated impersonation and future quantum attacks on current digital signatures.
According to The AI Lab, a TIP record links a work to its creator and includes the creator’s declaration of whether a person, an AI system or both made it. It is also intended to show whether the content has changed since the record was created. The company says the protocol combines ML-DSA-65 signatures, SHAKE-256 content fingerprints and a decentralized ledger. The source material does not specify the ledger’s governance, where records are stored, or how users can independently inspect its operation.
The company describes TIP as a way for journalists, authors, filmmakers and other creators to provide evidence about a work’s origin and integrity. For a news article, for example, a newsroom or reader could check a record associated with the story against the original. The protocol records a creator’s declaration; the material does not describe a process for independently verifying that declaration or resolving competing authorship claims.
The AI Lab draws a distinction between provenance and accuracy: TIP is intended to record who claims to have made a work and whether it was altered, not whether its claims are true. Its public availability is an announcement by the company. The supplied report does not include independent technical testing, adoption figures, or confirmation from outside researchers that TIP meets its stated security goals.
If it works as described and creators adopt it, a portable record of origin could help publishers and audiences distinguish an original file from a later alteration. That could be useful when content is copied, reposted or presented under another name. It may also give a newsroom a way to document who submitted a story and whether a particular version has changed.
The stakes extend beyond attribution. Digital signatures are used to establish that a message or record came from a particular key and was not altered. A sufficiently capable quantum computer could threaten some widely used cryptographic systems, though the timing and practical capabilities of such a machine remain uncertain. TIP’s use of a post-quantum signature algorithm is intended to address that future risk, while its content fingerprint and ledger provide other parts of the record.
Those functions do not settle questions of trust on their own. A signed record can support a claim about provenance, but it cannot show that a story is accurate, that a creator’s identity was checked, or that an AI-use declaration is complete. Users would need to understand what the protocol verifies and what depends on the person who creates the record.

Why Quantum Readiness Is on the Agenda
The announcement connects TIP’s design to changing estimates for how much quantum computing might threaten current cryptography. The AI Lab cites a 2019 estimate that breaking RSA-2048 could require a quantum computer with about 20 million qubits, a May 2025 estimate by a Google Quantum AI researcher of fewer than one million, and a February 2026 design study that put the figure below 100,000 physical qubits under specified engineering assumptions. These figures describe different estimates and assumptions; they do not establish when such a machine will exist.
The company also points to Google’s stated 2029 target for moving to post-quantum cryptography and to a 2025 Global Risk Institute survey. The report says respondents put the likelihood of a cryptographically relevant quantum computer within 10 years at 28 to 49 percent. That is a survey estimate, not a prediction of a confirmed arrival date. The AI Lab’s assertion that AI has shortened preparation time from about 20 years to about two years is its assessment, rather than a settled consensus in the supplied source material.
There is already a formal migration effort. In August 2024, the U.S. National Institute of Standards and Technology published its first post-quantum standards, including FIPS 204 for digital signatures. The report says draft transition guidance proposes phasing out quantum-vulnerable algorithms such as RSA-2048 after 2030 and disallowing them after 2035. These dates concern government cryptographic transition guidance; they do not validate TIP or establish a deadline for creators to use it.
““With AI accelerating quantum research, I believe we now have roughly two years to prepare.””

Open Questions on Security and Use
The supplied material does not identify an independent audit, describe how TIP’s implementation has been tested, or provide details needed to assess its security in practice. It also does not explain how the decentralized ledger is operated, what happens if a signing key is lost or compromised, or how a disputed identity or authorship record can be corrected.
Adoption is another unknown. The AI Lab says the browser extension and web app are available, but gives no user numbers, publisher partnerships or evidence of integration with major platforms. It is not clear whether recipients will be able to verify a TIP record without using the company’s tools, or how widely the protocol will be supported.
The quantum timeline remains uncertain as well. The estimates cited in the announcement depend on engineering assumptions and do not show that a machine able to break current digital signatures is imminent. TIP’s ability to establish provenance also does not amount to a check on factual accuracy, identity verification or the completeness of a creator’s disclosure about AI use.

Availability and Independent Review
The immediate next step is for interested creators and publishers to assess the browser extension and web app and determine whether TIP fits their publishing process. The AI Lab has announced public availability, but the supplied report gives no schedule for further releases, third-party integrations or an external security review.
Evidence that would clarify the protocol’s practical value includes published technical documentation, independent testing, clear procedures for key recovery and disputes, and examples of outside publishers using the records. Until such information is available, TIP’s launch establishes that the company has released the system; its security, reliability and reach remain to be demonstrated.

Key Questions
What does TIP record?
The AI Lab says TIP records a creator’s identity, the creator’s declaration about whether a person or AI made the work, and whether the content has changed since the record was made.
Does TIP verify that a work is true?
No. The company describes TIP as a provenance and integrity record. It does not establish whether the content itself is accurate.
What technology does the protocol use?
The AI Lab says TIP combines ML-DSA-65 digital signatures, SHAKE-256 content fingerprints and a decentralized ledger.
Is a quantum computer expected to break current signatures in two years?
The two-year timeframe is the AI Lab chairman’s assessment of how long the world has to prepare. The estimates in the announcement do not confirm that a quantum computer capable of breaking current signatures will arrive on that schedule.
Has TIP been independently audited?
The supplied report does not mention an independent audit or provide outside test results. The protocol’s real-world security and adoption remain unclear.
