Deepfake app. How can you tell a Deepfake? How do you spot a Deepfake ?

Deepfake app ? How can you tell a Deepfake? How do you spot a Deepfake ? 

These are the questions we recently feel the need to be answered as growing numbers of deepfakes are being crafted to support biased and destructive political agendas and to mould the information in sinister ways ,Deepfakes are the new technological war front that will act as a breeding ground for fake news in the coming years .


So by now we all are familiar with deepfakes you can take a photograph and impose a video over it to make it act and say in the way you want to for example look at this First Order Motion Model for Image Animation


Researchers have now found a way to carefully detect these deepfakes that fool human eyes with the help of an AI . they created an AI to beat another AI . We have entered a new age of internet security and forensics as seen here the AI can identify the deepfakes pretty easily .

shown here are the video samples are used one is the original and the other is a deepfake and the AI correctly identifies the tampered part of the video ,here the red part is the correctly identified tampered area of the deep fakes 





so the war is won over the Deepfakes?

NO Because using the algorithm that identify the deepfakes researchers have found a way to fool it with the help of addition of noise in the video that will Not fool any human eyes but the AI detective!

This is the AI detecting the correctly the deepfake 

                                

   

and this is after addition of noise , The AI is fooled !



here is how the noise is added to fool the AI , They added noise in every section of the video by learning from the detective classifier such that humans wont notice a thing but the classifier will be fooled 






 The classifier AI that's our detective is fooled with this simple thing

( more in details in the sources )


look the these images the AI detector detects them correctly at first but after the addition of noise the AI cant identify them correctly and is fooled easily into thinking its an ostrich !


Because of the noise added the internal working of the detective AI are now exploited into concluding the bus is an ostrich ! 

so the war is on and the innovation is leading like always .so always think twice before you see something nowadays check the source to the papers . 

check out the playlist of our favorite deepfakes , they are hilarious and confusing on so many levels :
