Deepfake

Written by Minh Khang

What is Deepfake?

A deepfake is a fake image, voice or video made by AI that looks like a real person or event, often hard to tell apart.

A cloned voice of a relative asking for money, a fake photo of damaged goods to claim a refund, a celebrity in an ad they never made: deepfakes are now cheap and fast. The best defence is to check through another channel rather than trust what you see or hear.

Deepfake in a shop

A customer sends a photo of broken goods for a refund: ask for an unbroken video or a photo from another angle first.

How does Deepfake work?

  1. 1An AI tool learns from photos, video or a few seconds of someone's voice.
  2. 2It produces new images, audio or video that look and sound like that person, or like a real event.
  3. 3Scammers use them for calls, messages or ads, usually with pressure to act fast.
  4. 4Deepfakes are now cheap and quick to make, so seeing and hearing is no longer enough to believe.

What a shop or café can use it for

  • Knowing the scams aimed at shops: fake damage photos for refunds, fake calls from people you know asking for money.
  • Setting a verification routine: ask for an uncut video, call back a saved number.
  • For AI content the shop makes itself (AI models, AI voices): label it clearly.

What to watch out for

  • Never send money because of a video call or voice message alone, however familiar it looks.
  • Do not use a real person's face or voice without consent: Vietnam's AI Law requires labels and bans using AI to deceive.
  • Deepfake detectors are unreliable; checking through another channel is still the dependable way.

Quick questions

  • A very short call, a face with little emotion, head and body out of step, sound out of sync, then pressure to transfer money to an unfamiliar account. With a few of these signs, hang up and call back a saved number.

  • Ask for an uncut unboxing video or a photo taken now from another angle, and match the order code. Real customers can usually send it at once.

  • Not a scam if you label them as AI-generated and they show the real product accurately. They become a problem when they use a real person's face without permission or mislead customers.
