What a deepfake is
A deepfake is video, audio or an image that has been created or altered with machine-learning tools so that it appears to show a real person saying or doing something they did not. The term covers a range of material: a face swapped onto another body, a voice generated to sound like a specific person, or a still image of an event that never took place.
The danger comes when the material is presented as real in order to deceive, defraud, embarrass or harass. The tools have become easier to use over time, so it is wise to assume that realistic fakes exist and to build habits that do not depend on spotting them by eye alone.
How deepfakes are used to cause harm
Impersonation fraud. A fake voice or video call that appears to come from a manager, a relative or a company executive can be used to pressure someone into sending money or sharing information. This overlaps with executive impersonation emails and voice cloning scams, which often add a fabricated emergency to rush the victim.
False endorsements. Videos of well-known people appearing to promote an investment, giveaway or product are a common way to lend fake credibility to online scams. A real person’s endorsement should be confirmed on their own verified channels.
Disinformation. A fabricated clip of a public figure can spread quickly before anyone checks it, especially in group chats where forwarded message hoaxes travel fast.
Harassment and abuse. Some people have had their faces placed into fabricated images or videos to humiliate or threaten them. This is a form of image-based abuse, and it is a serious harm even though the depicted event never happened. Those affected are not at fault, and help is available, as covered below.
Common signs of manipulated video
No single sign proves a clip is fake, and the best fakes show none of these. Treat the list as a prompt to slow down, not as a test with a definite answer.
- Odd facial details. Blurring or flickering around the hairline, ears, glasses or jaw; skin that looks unusually smooth; teeth or eyes that look slightly wrong.
- Unnatural blinking or eye movement. Gaze that does not match the situation, or blinking that seems too rare, too frequent or oddly timed.
- Lighting and shadow mismatches. Shadows or reflections that do not match the room, or a face that seems lit differently from the neck and body.
- Lip movement that is slightly out of sync with the words.
Common signs of manipulated audio
- A flat or oddly even tone, with little natural breathing, hesitation or background noise.
- A caller who avoids answering personal questions only you and the real person would know.
- An urgent request combined with secrecy: “do not tell anyone,” “I cannot talk long,” or “send it now.”
Verify the situation, not just the media
Because quality keeps improving, the most dependable defense is checking context.
- Pause. Urgency is the scammer’s main tool. A real emergency can usually survive a two-minute verification.
- Contact the person another way. Hang up and call back on a number you already have, or message them through a different known channel.
- Use a family or team code word. A pre-agreed phrase that is never posted online lets close contacts confirm one another’s identity during a suspicious call.
- Check the source. Search for the claim from reputable news organizations or the person’s own verified account. If a shocking clip appears nowhere else, be skeptical.
- Do not send money, gift cards or codes on the strength of a call or video alone, and follow your workplace’s approval process for payments, even when the request appears to come from the top.
If a call or clip was convincing enough that you already acted, contact your bank at once, since quick reports sometimes give a better chance of stopping a transfer, though it cannot be guaranteed.
Reduce what can be copied
Fakes need material to learn from. You cannot remove yourself from the internet, but you can make misuse a little harder.
- Limit who can see photos and videos of you by reviewing social privacy settings.
- Consider whether long, clear recordings of your voice or face need to be public.
- Keep your accounts secure with unique passwords and two-step sign-in.
If your likeness is misused
If you discover a fake of yourself, the following steps are sensible.
- Save evidence. Take screenshots, copy the web addresses, and note dates and usernames before anything is removed.
- Report it to the platform. Most major services have rules against impersonation, deceptive synthetic media and non-consensual images. Use the platform report tools and identify the rule involved.
- Ask the site owner or host to remove it if the material is on an independent website. Search services may also accept removal requests for some categories of harmful content.
- Report it to the authorities when appropriate. Fraud, threats, blackmail or sexual content involving anyone, especially a minor, should be reported to your local police and, where it exists, your national reporting channel. If someone is in immediate danger, contact local emergency services.
- Seek support. Being the target of a fake can be distressing. A trusted friend, family member or qualified counselor can help, and legal advice may be worthwhile because laws on synthetic media differ widely between countries and regions.
A balanced mindset
Not every odd video is a fake, and treating everything as false is also a failure of judgment. The aim is healthy skepticism: weigh the source, the context and the request, and verify before acting on anything urgent or surprising.
