Deepfakes are the new big threat to business. How can we stop them?

Vyacheslav Zholudev,Pavel Goldman Kalaydin June 22,2023

The authors started developing methods to combat this rapidly developing sort of fraud as soon as they became aware of the burgeoning deepfake trend. There company  Sumsub is consistently developing cutting-edge fraud detection solutions to fend against evolving hostile technologies and stop the potentially severe harm they could cause to digital platforms, users, and communities. The authors commitment to further developing the AI-driven technologies incorporated into there anti-fraud solution that is strengthened with the introduction of there new sophisticated deepfake detector.

Deefake Challenges ‘Will Only Grow’

Amanda Morris Jan 16,2023

A recent report by artificial intelligence (AI) and foreign policy experts from Northwestern University and the Brookings Institution sheds light on the widespread impact of deepfakes beyond the attention garnered by large propaganda campaigns. The report delves into deepfake videos, images, and audio, highlighting the associated security challenges. The researchers foresee an imminent increase in the usage of this technology, including its potential deployment in targeted military and intelligence operations. In response to these developments, the experts offer recommendations to security officials and policymakers, proposing the creation of a code of conduct for governments' use of deepfakes. This move is deemed crucial to address the concerns surrounding the use of this unsettling new technology by the United States and its allies.

Don't Trust Your Eyes: Image Manipulation in the Age of DeepFakes

Johannes Langguth,Konstantin Pogorelov,Stefan Brenner,Petra Filkukova,Daniel Thilo Schroeder May 24,2021

The authors explore the deepfakes phenomena in the light of the current, more general debate on fake news. Deepfakes is a breakthrough technology that enables low-cost alteration of video content through the use of artificial intelligence. They go into the history of the technology, its most recent advancements, how it differs from past manipulation tactics, and they look into technical defenses. Although deepfake films have the potential to have significant political repercussions, this technology has so far only had a modest political influence. They look at the causes of this and predict the kinds of deepfake films we might see in the future.

Interests

I enjoy traveling and engaging in outdoor activities like hiking and camping in addition to my work as a researcher. I am a big fan of astrophysicists and academics who study celestial bodies and space, and I follow up with many of them.

My favorite activity is also investigating culinary adventures. I also enjoy watching and playing cricket. In my free time, I enjoy going to the movies with my friends.
