Checkify
Privacy-first trust infrastructure

Verify with Checkify

Checkify lets businesses confirm humans, age, and eligibility with privacy-first proofs — not full identity dossiers. Users approve once; you get a yes/no result.

Checkify Pass: Verify > reusable trust > used everywhere.

Checkify Pass let's you confirm multiple proofs in a single request, such as whether a user is human, over 18, or approved for a specific action.

Onboarding a small number of early partners now. Start on one flow first.

Our mission

Make the world verifiable

We are building a privacy-first verification layer where businesses get trusted answers, users stay in control of their data, and the internet can confirm what is true without turning every site into a data vault.

Proof, not paperwork

The website receives a yes/no age result. Your date of birth stays on your device unless you choose to share more.

The problem

Businesses are stuck between friction, fraud, and data risk.

Most online trust tools either annoy genuine users or ask businesses to collect more personal data than they really need.

CAPTCHA adds friction

Image puzzles, delays, and repeated checks frustrate real users and interrupt important business flows.

Identity checks expose too much

A business may only need to know “over 18” or “human verified”, not store passports, selfies, or full DOB.

Data storage creates liability

Every extra piece of user data becomes something to secure, justify, audit, and protect.

Global risk

The global cost of unverified information

Every day, people and businesses are asked to trust identities, documents, claims and digital interactions they cannot independently verify.

$10.5 trillion

Projected annual global cost of cybercrime in 2025.

Many attacks begin with impersonation, stolen credentials or information being trusted without a reliable way to confirm its source.

How Checkify helps

Checkify allows businesses to verify specific facts, identities and permissions without relying solely on documents, screenshots or unverified claims.

$442 billion

Estimated global financial fraud losses during 2025.

Fraud succeeds when criminals can pretend to be someone else, make false claims or present information that appears genuine.

How Checkify helps

Checkify provides reusable, cryptographically verifiable proofs so businesses and individuals can confirm that important information is authentic before acting on it.

$4.44 million

The average global cost of a data breach during 2025.

The more sensitive information a business collects and stores, the greater the potential damage when its systems are compromised.

How Checkify helps

Instead of collecting passports, dates of birth and other unnecessary personal data, businesses can request confirmation of only the fact they need.

Verify what matters. Store less. Reduce the risk.

The Checkify answer

Ask for the proof, not the personal data behind it.

Checkify lets a business ask a narrow question, the user approves it, and the business receives a trusted result.

?

Business asks

“Is this person human?” “Are they over 18?” “Can this action be trusted?”

User approves

The user reviews the request and approves what they want to share through Checkify.

Website gets result

The website receives a trusted proof result without needing to hold unnecessary identity data.

Data Issuer Beta testing · Coming soon

Verified credentials from sources you already trust.

Data Issuer lets organisations sign privacy-first credentials — employment, training, membership, and more — that users keep in their Checkify wallet and present only when they choose.

U

For users

Import credentials from employers, schools, membership bodies, and other approved issuers into your Checkify wallet.

  • You control what gets shared — present a credential only when a business asks for that specific proof.
  • Sensitive claim details stay on your device; Checkify validates signatures without storing cleartext identity data in the cloud.
  • Reuse trusted proofs across sites instead of uploading the same documents again and again.
B

For businesses

Become a Data Issuer to deliver signed credentials to your customers, members, or staff — and earn revenue share when those credentials are used in Checkify verifications.

  • Issue attestations such as employment proof, course completion, or active membership from your own systems.
  • Requesters get a trusted result; you do not become a large identity data store for other businesses.
  • Approved issuers can track credential use and eligible revenue share in the business dashboard.

Data Issuer is in beta testing and coming soon. We are onboarding select partners first — business verification and Checkify issuer approval will be required before live issuing.

Signed Item Proofs

Sign any digital item — without uploading the file.

Create a cryptographic fingerprint of a document, build, or release on your device. Checkify stores only the hash and your signature — never the original bytes.

U

For users

Sign files from the Checkify app with your device key and verified identity.

  • Hash locally on your phone or in the browser — the file never leaves your device.
  • Choose how you sign: anonymous, verified legal name, or authorised organisation.
  • Anyone can verify the same file later by comparing fingerprints — no account required for public proofs.
B

For businesses

Create proofs from the business dashboard and collect organisation signatures from authorised team members.

  • Sign software releases, contracts, policies, and internal documents with audit metadata.
  • Set signing policies such as organisation plus individual approval.
  • Share private proofs via magic links; revoke signatures without deleting audit history.

Try Checkify as a CAPTCHA alternative.

This is the simplest Checkify flow: a website asks for human verification, the user approves through Checkify, and the website receives a trusted result.

Why this matters

CAPTCHA is the first use case because it is easy to understand and painful for users. But the same proof-based approach can support stronger verification later.
