The use of deep fake videos and Audio integrations have increased over the years with the use of AI and machine learning technology. We have come a long way with the advancement in these technologies and the implications have been of great use to mankind.
However, it can be a lot more dangerous than one could ever hope for. Who would have thought that people can think of something such as DeepFake and create havoc?
You must have used the face swap feature by Snapchat where you can take up the face of your friend or anyone being on the camera at the same time. Well, DeepFake videos aren’t the same but on a much-advanced level.
However, such videos and audios are being used only as a part to prank or in a harmless manner. But no one knows when this can take a much more dangerous turn if it gets into the hands of wrong people.
With the widespread nature of such activities, a lot of social media platforms have banned anyone who is found sharing such forged videos or audios.
They have been taking proper measures so that it does not reach the mainstream platforms and create an impact over the world and the lives of other people.
Let us learn more about DeepFake and its impact.
What is DeepFake?
DeepFake is the combination of two words i.e. Deep learning technology such as Machine Learning and AI along with the word Fake to create false information by forging the actual data.
These are synthetic media such as Audio and Videos where your face or even your voice could be replaced by someone else to create a false portrayal.
Such actions are created by the help of deep learning and generative neural network architectures, such as autoencoders or generative adversarial networks (GANs).
There have been numerous such media being circulated all over the web and are being used in multiple illegal activities such as fake news, hoax, cyber fraud, financial fraud, videos, revenge po#rn, and a lot more similar activities.
A lot of such cases had been reported the last year 2019 and the Government had taken the decision to limit the use of such technology so that it causes no further damage.
How does DeepFake work? 🤔
We all know now the technology used by DeepFake works but it is not as easy as the Face Swap feature. This is a lot more complex since it uses the neural network architectures and makes the necessary changes using the encoding and decoding pattern of the Image.
The architecture mostly commonly used here is the autoencoders that handle both the encoder and the decoder.
Here the encoder tends to use the source of an image and reduces it to a lower-dimensional latent space. On the other hand, the decoder has the ability where it reconstructs the image that has a lower latent space.
The main aspect is the face structure that is taken care of by the latent representation. Furthermore, the target image’s information is superimposed on the original videos and replaced by the source. All of this can be a little too complicated to understand by everyone and hence it has not entered the mainstream media yet.
However, this is only the traditional method that was followed earlier. Currently, people have been using the much more advanced tech i.e the generative adversarial networks (GANs).
It was introduced in 2018 by Ian Goodfellow, who was a Ph.D. candidate at the University of Montreal. This technology is not a piece of cake and thus could not be as troublesome as it may look like.
In the most non-technical aspect possible, this is not an easy job to carry out by any random person. With the availability of technology and machines, you can easily get the right device to create such DeepFake at your home. But it requires a ton of effort and long hours of work.
From gathering multiple images of the source face. It needs to be available at every angle and a similar aspect goes for the actor or person in the original video so that they can be swapped or replaced to make it look legit.
What is Audio DeepFake?
Audio DeepFake is the process where the original voice from any video or any media can be easily altered or swapped. Unlike the DeepFake Videos on the internet that are being circulated, such audio manipulations have not gotten enough attention as it should.
These alterations in someone’s voice can be a potential threat on multiple levels. You will find multiple such examples where the company can create accurate human voices of anyone and add it to either the original video or even create one with just an image.
DeepFake Audio Example – Neural Voice Puppetry
Neural Voice Puppetry is one such example that will help you understand how easy it is to forge anyone’s voice and add it to someone else.
It can be you, me, or even the President. This project or better say concept shows an Audio-driven Facial Reenactment that works on the neural network technology that employs a latent 3D face model space.
Here any Image of a celebrity can be picked up and with the help of neural leverage, it can be controlled with the source head movement and facial expressions. Also, either the source voice can be added to the image or with the help of text-to-speech technology, you can even add the voice of the original person in the image.
It is an impeccable technology demonstration however can create a huge impact if it falls in the wrong hands. Apart from creating Audio DeepFakes, here is some other application of these projects that includes audio-driven video avatars, video dubbing, and text-driven video synthesis of a talking head.
Such technology of forging someone’s voice has been underway in the past as well when people used to receive calls for fraud.
But currently, the scenario has taken a much further step and it has become even more difficult to distinguish between real and fake.
The above video created by BuzzFeed clearly shows how far we have come and how easy it is to create something that you can never know is fake or real. This is one such example while there are a lot of such videos and apps too where anyone can create such videos.
The most common results and the application you might have come across have been in the terms of DeepFake Audios. Not only have the celebrity videos been forged and tampered, but also it has been illegally used in po#rnography where a celebrity’s face has been seen swamped in some of these videos.
Apart from this, the most dangerous of all is the revenge pron where people are harassed by using their images to use them in videos in order to take revenge.
Since it is very difficult to recognize the fake videos from the real ones, criminals have been using it for quite some time now posing a bigger threat in the foreseen future.
There have been multiple such cases that were reported in the year 2017. In fact, according to a cybersecurity startup Deeptrace in the year 2019, 96% of all the DeepFake videos were Po#rnographic.
On the other hand, such videos are also used in Politics as well. Even though these might not be used as often, still the words are hardly something one can trust and with this technology, things can take an ugly turn pretty quick.
DeepFake Video Example:-
Here is a quick example that will help you understand more about how these videos look like and the impact it has on the viewers. The video below shows the compilation of the most famous and viral Deepfake videos on the internet.
It shows how easy it is to simply swap the celebrity faces with a different one and make it look legit. Not only can you make the face swap as clean as possible but it fits in perfectly well with the help of neural networks technology the voice change over works as well.
There is no way one can even understand if it is real or not. Hence, the time isn’t far away when the world might witness the effects on a global scale which can be quite troublesome.
Applications of DeepFake
Some of the major applications that have already been implemented for years are listed below. It is not only limited to celebrities or po#rnography but in multiple sectors as well. Here it goes:
One of the major applications of DeepFake technology in the current scenario has to be by swapping faces or the voice of powerful politicians.
It has become a huge sense of worry since anything can go wrong and it becomes very difficult to know what could be true or not. Some of the examples that had happened earlier are as below.
- The Belgian branch of the Extinction Rebellion used DeepFake and published a video of the Belgian Prime Minister Sophie Wilmès on Facebook in April 2020. A lot of people believed the video to be legit and gained thousands of views.
- In Jan 2019, A DeepFake video of Trump had been circulated by Fox affiliate KCPQ.
- In April 2018, a public awareness against DeepFake technology had been created by Jordan Peele in collaboration with Buzzfeed where the video was based on Barack Obama.
All of these are only a few of the examples you might have already come across and a lot more are available on media platforms as well.
2. Film Dubbing
Well, not all the applications of DeepFake need to have a negative impact. One such could be the use of it in Film Dubbing. A video had been created starring David Beckham to spread the message and to end Malaria.
The video features the famous footballer speaking in nine different languages. He is seen simply moving his lips whereas a female voice-over comes in as well while depicting him behind the voice.
In such a case the DeepFake technology has been used to change his facial movements and the voice.
This particular option shows the opportunity this technology can bring to the film industry and how it can be used for social experiments. In fact, in the future, it can be used to dub films in multiple languages to make it available all around the world.
One of the most disturbing negative effects of DeefFake Videos is po#rnography. Imagine the use of this technology and how it has been implemented to alter the faces in the videos with that of celebrities. Most of these have been of female celebrities without their consent. Such a video started circulating from Reddit in 2017.
Other than this, there have been reported cases of revenge po#rn where people have used DeepFake is the sense to harass anyone or take revenge. There have been several cases related to such incidents both in 2018 and 2019.
Another positive aspect of the Deepfake videos that one cannot implement is by applying it to the education sector. Have you ever wondered about the impact if any of the historical people would tell their own story someday?
Yes, it can be made possible. Using this technology and simply an image, one can create the words said by some of the famous personalities who are no more among us. It will change the way we perceive things and also the history classes will finally not be boring anymore.
How to detect a DeepFake Video?
It is not an easy job for anyone to be able to detect such fake videos or forged media. Some of them are way too unrealistic and can be easily understood if one looks closely enough.
However, some of the videos we have shared stand no chance that anyone with the first look could have detected that it is in fact not legit. With the use of AI technology and neural network, these videos have started to look a lot more legit than the original ones.
Some of the common signs that people tend to detect are, by the way, the DeepFake faces blink and even the shadows of these fake videos.
Earlier, the issues while creating such videos included lip-sync, blinking, etc but as of now the use of GAN’s technology has made the videos look smarter and more real.
Apart from all this, some of the common mistakes that you can make out from the videos are flickering around the edges of transposed faces, hair, eyes, and all the small details on the face.
5 of the Best DeepFake Apps or Websites
Apart from everything that has been around the internet with the use of Deepfake videos and audios, there is a lot to learn about how it can be used for something positive.
Well, that is a long road, however, you can find multiple apps on the web where you can try this out as well but only for fun purposes. These apps or websites can be utilized to learn more about Machine learning and AI. Let us get on with it.
1. Deepfakes web β
Deepfakes web β is a web-based software that uses a machine-learning algorithm to face-swap the subject with another. The process is pretty simple here to use the application.
Simply upload your video and make the changes as needed. Further, wait for the video to be recreated. However, it is not as easy as it does sound. The app takes about 4-5 hours in just learning the video and another an hour makes the swapping.
Once your model is trained from one video, you can reuse it again for other projects as well. This will save you time and also give you the results much faster. Deepfakes web β is not a free site and requires a small amount as you need to pay to use the service.
Zao is currently the most advanced Deepfake app that has been created by a Chinese company and has taken the internet by storm. However, it is not available for the entire world. Only those living in the country can access it on their smartphones.
The video created on this app is a lot more authentic and legit than any other apps or websites you might come across. It hardly takes seconds to create your desired video and the process is pretty simple as well.
The app allows users to swap celebrity faces and even make voice modulation. It already has a library where you can easily find hundreds of clips from series, movies, Images, etc that can be used directly for face swap.
However, it may not be the best one for people outside of China since it has been trained based on their faces.
3. REFACE: face swap videos
Reface is a face swap video creation app available for both Android and iOS users. It is more inclined towards using it for fun purposes and not anything that can be on the harm’s way.
Anyone can use it since it is free of cost. You can use this app to create hyper-realistic videos and Gifs by simply uploading your image. Create new videos every day by swapping your face on the celebrities or any GIF and sent to your friends for fun.
It has been loved by users everywhere and follows every privacy norm considering the use of the Deepfake concept.
This app is powered by the Reface AI that has been known for its impeccable implementation of ML/AI technology for face swap and the algorithm that makes it possible.
4. FaceApp – AI Face Editor
FaceApp is powered by AI Face Editor that uses the most advanced neural face editing technology. This deepfake app can help you make gender swap, hair styling, modify, creation, and other free & fun features.
Some of the features of the app are changing hair color & style, applying makeup, adding a smile, replacing the background with a single tap, trying old and young filters, add tattoos, and a lot more activities.
The app had created a huge buzz with people all around the globe with its gender swap feature. It looks highly realistic and makes the switch very smooth without any errors.
Are you a Marvel fan? If yes, then you are going to love this deepfake website. You can easily use the list of GIFs on the home page and swap your face with it. Although the entire concept isn’t directly related to Deepfake but rather a static 3D model of your face.
The face app looks pretty cool and legit as well. Anyone would hardly be able to make it if you are wearing a costume or it is photoshopped.
As of now, there are in total 18 GIFs on the site of the most popular scenes from the Marvel Cinematic Universe. You can choose your favorite character and make the swap. Simply choose the GIF, upload your image, and click on submit. That is it.
Here is everything you need to know about Deepfake and how it has been influencing the current world and what foreseeable future it has.
There are a lot of issues related to its applications however, we cannot ignore the good aspects as well since it uses the most advanced technology i.e. AI and ML. Also, there is a lot to be learned from such applications since it can be used with tons of other aspects as well.
However, the government is strictly monitoring any false image or videos being circulated on the web so that it poses no harm to anyone. There is a lot to come in the coming days where the actual implementation of this technology will be seen on various platforms.
Even though it is being monitored but still it is not possible to get rid of all of them with billions of people in the world. You can visit multiple sites that will help you learn more about the technology behind it since it surely isn’t as easy as it looks to create Deepfake videos or images.
