Cross-channel identity verification

Three words. Every channel. One human.

Voice call, video conference, text message, email, QR — the same code proves the same person, everywhere the conversation goes.

AI clones any voice and face — and attackers no longer pick one channel. They follow the deepfake call with a 'confirming' email and a text-message follow-up. One question closes every door at once: "What's your code?" If the three words match, it's really them. If not — hang up, delete, walk away.

The cross-channel attack

Fraudsters don't pick one channel. Your defence shouldn't either.

Voice call
Video conference
Messaging
Email
QR / silent

1
A deepfake call confirms itself via a 'matching' email — then a text-message follow-up keeps the pressure on.
2
Channel-specific detectors guard one door at a time. The attacker just walks to the next one.
3
One code, asked in any channel, closes all of them.

One identity. Every surface the conversation touches.

This Already Happened

$1.3M stolen by fake 'bank fraud teams' in one Canadian city.

voicein-person courier

Between March and August 2025, 15 Calgary residents received calls from people claiming to be their bank's fraud team. The callers were convincing: they described unauthorised transactions and sent couriers to collect cards and PINs for 'safekeeping.' Three suspects aged 22–25 were arrested after search warrants executed on April 14–15, 2026. Total losses: $1.3 million. A bank-issued Trusted Code on the call would have stopped every one.

AI voice cloning needs just 3 seconds of audio. Your voicemail is enough.

INTERPOL warning · October 2026

INTERPOL now warns the public: the voice you trust can be copied.

On 19 October 2026, INTERPOL started a campaign about scams with AI-generated faces and voices. Its advice is to check every unexpected request through a channel you already know.

A call from someone you love. A voice copied from a few seconds of video.

Criminals copy a real person's voice and face from material they find online. INTERPOL's advice to families: agree on a safe word before you need it.

With Trusted Codes: your family shares three words that change at a set interval. A copied voice cannot know the current words.

The CEO asks for an urgent transfer. The face is real. The person is not.

INTERPOL tells businesses to require more than one check for every financial transfer. Urgency and secrecy are the warning signs.

With Trusted Codes: the employee asks for the CEO's current code. A deepfake has no phone that shows it. No match, no transfer.

Simple Verification

Verification in 3 seconds.

1
Add your people
Connect with family, friends, or colleagues once — in person or via a secure invite.
2
Codes appear automatically
Three words, unique to each person, that change every few hours. Nothing to memorize — just open the app.
3
Ask "What's your code?"
If the three words match — it's really them. If they can't answer — hang up.

Shown: two people who both use Trusted Codes. A person without the app gets an invitation link and is guided through sign-up first.

Example Code

Mountain. Coffee. Bicycle.

Words create mental images. They stick. They're easy to say on any call, even when you're stressed.

Detection vs. verification

Stop trying to catch the fake. Start verifying the human.

Detection tools ask "is this video/voice/message fake?" — a question that gets harder every month. Verification asks "is this actually the person I think it is?" — a question that doesn't get harder as the fakes improve, because it doesn't depend on catching the fake at all.

Detection (the arms race)

One tool per channel — separate products for video, voice, email
Gets harder as fakes get better
Defender pays more every cycle of the arms race
User asks: "is this fake?"
Mental load: which tool do I trust on which channel?

Verification (Trusted Codes)

One layer across every channel
Doesn't depend on spotting the fake at all
One subscription, no model retraining
User asks: "is this them?"
Mental load: one habit, every channel

Detection tools keep improving, and you should keep using them. But they're a patch on individual channels. If the attack is cross-channel, the proof of authenticity has to be cross-channel too.

The Question That Matters

When their voice sounds perfect and their face looks real...

How will you know it's them?
