  Under the aegis of computer vision and deep learning technology, a new
emerging techniques has introduced that anyone can make highly realistic but
fake videos, images even can manipulates the voices. This technology is widely
known as Deepfake Technology. Although it seems interesting techniques to make
fake videos or image of something or some individuals but it could spread as
misinformation via internet. Deepfake contents could be dangerous for
individuals as well as for our communities, organizations, countries religions
etc. As Deepfake content creation involve a high level expertise with
combination of several algorithms of deep learning, it seems almost real and
genuine and difficult to differentiate. In this paper, a wide range of articles
have been examined to understand Deepfake technology more extensively. We have
examined several articles to find some insights such as what is Deepfake, who
are responsible for this, is there any benefits of Deepfake and what are the
challenges of this technology. We have also examined several creation and
detection techniques. Our study revealed that although Deepfake is a threat to
our societies, proper measures and strict regulations could prevent this.
