The many dangers of Facial Detection and Recognition Technology in the Digital Age
This was originally formatted for a presentation at my college, but I found the topic interesting and extremely relevant. Therefore, I made the decision to publish it on medium and my blog.
You will learn that facial recognition is advancing at a scary pace and its implications will have a lasting effect on all of us.
So let me ask you: What makes your face unique from anyone else’s? (Pause)
Here is a simplification of this long process which I broke down to 3 steps:
A popular method of detection
· is the Viola-Jones Algorithm (Paul Viola and Michael Jones), invented way back in 2001 and I’d like to expand on how it works.
o Changes the image to monochrome
§ Then it splits up the face into 4 regions
· Your face has different landmarks… regions around your cheeks are generally much lighter than the regions around your eyes — referred to as “Haar Features”
· It can infer the difference between the dark and light points and match it within it’s algorithm
o Now, it can determine if there is a face in an image with surprisingly good accuracy. It then draws a bounding box around the face and crops around it
Let’s move on to facial analysis:
· We use Facial Geometry:
o Which measures the distance between your eyes, nose, and bridge
o In addition to several more points such as the depth of your eye sockets
Lastly, we have the Signature stage:
