New technique keeps your online photos safe from facial recognition algorithms - Help Net Security

In one second, the human eye can only scan through a few photographs. Computers, on the other hand, are capable of performing billions of calculations in the same amount of time. With the explosion of social media, images have become the new social currency on the internet. Today, Facebook and Instagram can automatically tag a user in photos, while Google Photos can group one's photos together via the people present in those photos using Google's own image recognition technology. Dealing with threats against digital privacy today, therefore, extends beyond just stopping humans from seeing the photos, but also preventing machines from harvesting personal data from images. The frontiers of privacy protection need to be extended now to include machines.
