A new guide helps detect fake videos

Many bizarre fake videos have made headlines in recent years, as artificial intelligence (AI) is used to process videos and audio in a way that mimics reality.
Full Fact, an independent British fact-checking organization, defines a “deepfake” as “video or audio created using artificial intelligence tools to semi-successfully mimic the face or voice of a public figure.”

With the spread of fake videos increasing day by day, Full Fact has released a new guide on how to spot fake videos.

1. Check the shape of the face (and ears)

One of the easiest ways to tell if a video is a deepfake is to check the shape of the face.

In an interview on YouTube, Chris Omi, an artificial intelligence artist, said: “Face shape is always key. In many cases, the measurements are not perfect.”

The difference can be detected by placing an image, or some images, next to the video for comparison.

In particular, Omi says you should pay close attention to the ears, which are difficult to fake.

2. Find the original footage

If you can't spot any facial shape issues, Full Fact recommends checking if you can find the original footage.

You can do this by searching for keywords on platforms such as Google, YouTube, and TikTok.

However, if the video doesn't have any specific features to look for, Full Fact recommends performing an image search using screenshots of key parts of the video.

3. Scrutinize expressions and behaviors

If the video features a celebrity or public figure, see if you can spot any of their special behaviors.

Professor Hani Farid, an image forensics expert at the University of California, Berkeley, calls these tags “soft biometrics.”

4. Balance the eyes

Deepfakes often have problems aligning the eyes, according to Omi, who said: "Only in still frames can you detect those inconsistencies."

To check the alignment of the eyes, pause the video several times, and check if the eyes are looking in the same direction.

5. Look for visual glitches

Fake videos may look convincing when the person is facing the camera, but that's not the case when filming from the side, according to Full Fact.

“You may be able to spot such errors if you slow down the footage,” Full Fact said. “This will make it easier to notice any points where the technology fails to perfectly match the AI-generated face with the real part of the video.”

6. Properly synchronize the audio with the video

Full Fact recommends analyzing the wide positions of the mouth when producing different letter sounds.

Experts said that there is a specific shape that your mouth makes when you make certain sounds.

If you slow down a fake video, you may be able to observe the shape of the mouth to check that it matches the audio.



Apple releases the second iOS update in about a week and recommends it to all users!

Apple announced the launch of a new update for iOS systems, approximately a week after it launched the iOS 17.2 update.
Apple did not mention the features included in the new iOS 17.2.1 update, but it indicated that it addresses some technical problems in iPhones, “provides important bug fixes, and is recommended for all users.”

Rumors indicate that the new update is supposed to address the problems that some Apple phone users recently complained about, as the iMessage shortcut disappears from the phone’s main screen when the icons are rearranged.

Apple's new update angers users!
To obtain the new update, the phone user must go to the “Settings” menu on his device, then the “General” option, then the “Software Update” option, and finally press the “Download and Install” option.
