What
is deepfake technology? How it works - Disadvantages of using Deepfake
Technology
Deepfake technology is one of the most popular application, which has a magical application, but did you ever think why Deepfake is getting the popularity?
Let me tell you, why Deepfake
is getting that popularity and what is Deepfake technology? So Deepfake is
basically part of deep-learning where you will actually do some of the amazing
tasks and that can make a human fool as well.
So,
what is Deepfake?
Deepfake technology is Synthetic
Media in which, a person in an existing image or video is replaced with someone
else's likeness. So if you want to change someone's face with like someone
others face you can do that by using Deepfake. While the act of faking content
is not new, Deepfakes leverage powerful techniques from machine learning and
artificial intelligence to manipulate or generate visual and audio content with
the high potential to deceive.
So
here, what is Deepfake stands for?
Deepfake will become Deep
Learning plus Fake if we break the name. So basically it's a part of artificial
intelligence and we use the deep learning techniques like GAN to do all these
things.
Now
let's have a look at the main machine learning methods used to
create Deepfakes are based on deep learning and involve creating generative
neural network architecture, such as auto encoders or generative adversarial
networks. That is GAN, Deepfakes have garnered widespread attention for their
use in celebrity, bold videos, revenge, fake news and financial fraud.
In the example, you can see
that it's a Deepfake technology we use in a scene from man of steel actress Amy
Adams in the original left. And it's modified, to have the face of actor
Nicholas Cage, So this is how the Deepfake actually, this is an interesting
application. So you can use this application for some better development as well.
Now, let's have a look at the most popular Deepfake. That is USA president, Donald Trump.
You can see in the image that
Donald Trump's face is actually put into some other one’s body, right? So this
is how our Deepfake technology works. So this has Better Call Trump.
Why
we are using Deepfakes?
The technology offers
interesting possibilities, which include dubbing, improving and repairing video
content, solving the Uncanny Valley effect in the video games, avoiding actors
having to repeat fluffed lines or mistakes. The creation of apps that allow people
to try clothes or different hairstyles and train doctors. So these are the most
useful uses of Deepfake. We can make our life easy by using Deepfake
technology.
Now let's have a look at some
popular deepfakes. You can see the Bilawal Bhutto actually replaced by the
Deefake. This is quite funny, right?
Disadvantages
of using Deepfake Technology
Now, we will have a look at
the nefarious uses of Defakes that are actually harming our society, like
misusing celebrity images for explicit adult content, misusing political figures
image for propagating false propagandas and financial crimes. These are all
negative part of the Deepfake technology.
How
are Deepfakes made?
You can see that Donald Trump
most useful or most popular Deepfake of Donald Trump. So basically in the
Deepfake, what we do, we use a generative adversarial network. So this network
has two parts. One is Generative part another is the Discriminative part.So
what actually it does? So in this case, we put some noise to our generator and
generator does not have any idea about the actual image and in the
discriminator we put the both images, the generator generated images and the
actual image. So for that our discrimination can say this is a fake image or a genuine
image, right ? With time we train our generator and discriminator both. and our
generator and discriminator become this much efficient enough that our
generator able to make an image like a real one. So if you don't see the person
before, you can say that maybe this is an actual image, right? So GAN actually
makes us fool. So in that case, our discriminator becomes that much efficient
to say, no, whatever the real image like a replica of real image you try to make,
but this is still fake. The actual images is the actual image you have provided.
So this is how our Deepfake
technology work.
O wow very useful information
