Deep Fakes Used To Manipulate Real Time Video Conference With Berlin Mayor



(New York, N.Y.) — Deep fakes appear to be playing a role in the
Russia-Ukraine war, demonstrating its potent potential. Recently, Berlin Mayor
Franziska Giffey spoke on avideo call

with an individual posing as Kyiv Mayor Vitali Klitschko. Giffey abruptly
ended the call when the imposter began asking her series of questions that were
“unusual” within the context of the war, causing her to question the identity
of the individual on the other end of the line.



Counter Extremism Project (CEP) Senior Advisor and University of California,
Berkeley professorDr. Hany Farid
<[link removed]> has long emphasized
<[link removed]> the threat that deep fakes pose
to national security and the world-altering impacts of this
technology—especially in war time.



“Deep fakes pose a serious threat to national security, particularly as the
technology advances and especially in the fog of war when false news about
foreign policy, the military, and terrorism can easily spread,” said Dr. Farid.
“Following Russia’s invasion of Ukraine, we have already seen deep fakes used
more frequently. Although the recent incident involving the mayor of Kyiv
appears to have avoided any catastrophic consequences, it remains only one of
many instances. For example, in March, there was a deep fake of President
Volodymyr Zelenskyycalling

on troops to surrender that circulated across social media. As these kinds of
videos become more believable, it is clear the consequences could be dire.
Governments and the tech industry must be ready to combat deep fakes as another
front within modern warfare.”



Following earlier deep-fake videos of Zelenskyy, Dr. Farid and student
researcher Matyáš Boháčekdeveloped <[link removed]> a “facial
and gestural behavioral model that captures distinctive characteristics of
Zelenskyy’s speaking style.” This behavioral model can differentiate between a
real video of Zelenskyy and a deep fake, creating an important safeguard
against imposters especially at war time.



With the growing threat for real time deep fakes and the use of them in video
conferences, Dr. Farid along with Dr. Candice Gerstner of the National Security
Agency, also recentlywrote
<[link removed]> about a
technique, active illumination, for detecting real time deep fakes during live
video calls:“This technique leverages the fact that a video call typically
places a user in front of a light source (the computer display) which can be
manipulated to induce a controlled change in the appearance of the user’s face.
Deviations of the expected change in appearance over time can be measured in
real time and used to verify the authenticity of a video-call participant.”
