When anyone can generate a realistic photo, video, or article with AI in seconds, how do you prove that a post under your name is actually yours? How do readers know what to trust? TIP gives you a cryptographic way to sign your content with a verified identity and honestly declare how it was made. Other people can then tell your real work apart from impersonation, deepfakes, and unattributed AI output, on any site where your audience reads you. FOR CREATORS First, get a verified TIP-ID from an accredited Verification Provider. The VP runs a one-time biometric and government-ID check (about 10 minutes) and issues you a TIP-ID plus a private signing key. After that, whenever you publish:

Open the TIP panel on the page.
Pick the origin code that honestly describes your content: Original Human, AI-Assisted, AI-Generated, or Mixed.
Click Register. The extension signs the content using post-quantum cryptography (ML-DSA-65) and records it on the TIP Protocol decentralized network.
Paste the resulting Content Trust Identifier (CTID) into your post. Anyone who clicks it can verify your signature, your identity, and your origin claim.

FOR VIEWERS When a post contains a CTID, the extension shows a trust badge next to it with the signer's identity, their declared origin, and whether the signature is valid. This lets you:

Spot impersonation and deepfakes before you share them.
Confirm that a controversial or viral post actually came from the claimed author.
Distinguish human work from AI-generated content, even on platforms that do not label AI themselves.

Verification is independent of the hosting platform. No platform can fake, alter, or take down a valid TIP record, because the signature is verified against a decentralized network, not a platform database. PRIVACY Your private signing key is encrypted on your device with your biometric (Face ID or Touch ID) or a password, and stored only inside the browser's extension-storage sandbox. It never leaves your device. Not to us, not to Mozilla, not to any third party. The extension does no tracking, includes no analytics, and uses no third-party services. The source code is open and you can audit every line. Data is only sent when you explicitly click Register, and only to the TIP node you configure (the default is the public network node). What is sent: your public TIP-ID, your declared origin code, the text of the content you are registering, cryptographic hashes, and the signature. Nothing else. FREE AND OPEN There is no subscription, no paywall, no advertising. The protocol is built as a public good.

Artists who want to declare which of their pieces used AI and how much. Scientists binding their attribution to a verified identity. Public figures guarding against deepfakes. And anyone whose online credibility depends on being able to prove that their words, photos, and videos are actually theirs, in an era when generative AI makes impersonation nearly effortless.
