Deepfake: what is it, 3 real cases and how to detect it

The deepfake It is another example of how technology is getting closer to not being able to differentiate it from reality. Imagine hearing some controversial statements by former President Obama, or a revealing statement from Zuckerberg and it being false. But how? If you are seeing it with your own eyes. It’s possible! Find out below.

What is deepfake?

Deepfake is a term that refers to deep learning or deep learning, which is a form of Artificial Intelligence. Now, these algorithms deep learnings they are characterized by learning by themselves how to solve problems. Especially when dealing with large amounts of data. For this reason, they are able to create a realistic appearance when exchanging faces in a video.

In this sense, the method for creating fake digital content with realistic appearance. A common example is videos where face swapping is done. To do this, a video is used as a base and the video of the person to be inserted. Subsequently, an automatic encoder will be in charge of studying all the angles of the person and then mapping them to the destination video.

Finally, it is used Generative Adversarial Networks (GAN), a type of deep learning, which is responsible for detecting and improving any failure. Currently, you can find a variety of software that comply with this method perfectly. The result is a video so realistic that it is difficult to identify as fake.

3 very controversial real cases

According to BBC News, celebrities are the most common victims. One of the most emblematic cases is related to theactress Emma Watson. Her face has been used to replace that of a **** actress. Like this, cases abound in ***********.

On the other hand, according to El Confidencial, the actor jordan peele starred in a video for BuzzFeed, in which this technology was used to replace his face with Obama’s. In the video, the former president can be seen saying, “President Trump is a complete *******.” Although at the beginning of the recording it is noted that it is false, the realism was noted. For his part, Jordan Peele used this to raise awareness about deepfake and its possible consequences.

Continuing with this controversy, the artists Bill Posters and Daniel Howe created a fake video about Mark Zuckerberg, creator of Facebook. According to El Universal, in this recording Mark can be seen boasting of his power worldwide. However, creating him also wanted to alert about the spread of fake news.

Tips for detecting deepfake

According to IEBS – Business School, it is becoming more and more complex to detect a deepfake. Well, as technology advances, Artificial Intelligence allows get more and more realistic results. However, the best tips to identify it are:

  • Algorithms are not capable of blinking at the same speed as a human. Therefore, a clear sign is check if the person blinks much less than usual.
  • For the most part, these videos are a face substitution. Consequently, it is possible to find differences in the face and neck. This is an easy way to identify if content is fake.
  • Since it is a facial substitution, it is possible to see a blur inside the mouth.
  • Generally, these types of videos lacks synchronization with the sound.
  • The source of the recording is essential to verify its veracity. If the context is unreliable, it is possibly another case of deepfake content.

Now, it is important to note that everything about deepfake is not necessarily negative. This technology could also mean a great progress in health, education or cultureproviding new opportunities yet to be explored.
