The Invisibility Cloak

No, not like this

Let's make you Invisible from the surveillance cameras

Surveillance

Surveillance in India

Big Brother is watching you!

And China is not alone!

Surveillance systems around the world

• South Wales
• Maryland Police Department
• DeepFace by Facebook

Now they don't even need a CCTV camera anymore

They're saying it's there to protect us

But how much Privacy are we willing to give up to be safe?

Is there any solution then?

Adversarial Attack

With the addition of carefully constructed noise to the input image, we can fool the neural networks!

Yeah, it's a kinda optical illusion but for the Neural Networks.

We humans won't find it suspicious, but the system classifies the right image as a speed limit of 45 mph

Adversarial Patch

A patch that can be places anywhere within the field of classifier and cause the classifier to output a targeted class.

Adversarial Patch

Hmm,

seems interesting

But how can we use it be invisible from surveillance systems?

Adversarial Patch against YOLO

Adversarial Patch in Real World

Demo time!

Defense against the Adversarial Attack

Defenses do exist, but incur some cost

Similar to spam vs. anti-spam, we may be in an arms race for some applications
