Fawkes: Protect your photos from face recognition

Fawkes is one open source software that uses artificial intelligence to subtly modify your photos to fool facial recognition software.

Well-known face recognition poses a serious threat to privacy. The idea that the photos you share on the internet are collected by algorithm training companies, which in turn are sold commercially, is quite disturbing. Theoretically anyone can buy these tools, take a picture of a stranger and find out who they are in seconds.

Worse still, such a huge base could be leased as a service provider with the help of a fast wireless GSM internet, like the 5G that is coming, to be able to see the name of every person who passes by you.

Although we are still far from such an ominous situation, researchers have already started it γάτας – ποντικιού. Μία λύση στην αναγνώριση προσώπου είναι ένα εργαλείο που ονομάζεται Fawkes και δημιουργήθηκε στο εργαστήριο Sand Lab του Πανεπιστημίου του Σικάγο. Ονομάστηκε Fawkes από τις μάσκες του Guy Fawkes που φορούσαν οι επαναστάτες, στην ταινία V for Vendetta.

The Fawkes software uses artificial intelligence to alter your photos, in a subtle and almost imperceptible way, to trick facial recognition systems.

See for example the following photo of Queen Elizabeth, with the left one being normal and the right one being "teased".

The way the software works is a bit complicated, and passing your photos through Fawkes doesn't make you invisible to facial recognition. Instead, the software makes subtle changes to your photos so that any algorithm that scans those images in the future will see you as a different person. Essentially, fawking your photos is like adding an invisible mask to your selfies.

Its makers call this process "cloaking" and rely on destroying points that face recognition systems read and rely on. Αναφέρουν το παράδειγμα της εταιρείας αναγνώρισης προσώπου , which claims that has collected about three billion images of faces from sites such as Facebook, YouTube and Venmo, which it uses to identify strangers. But according to the creators of Fawkes, if the photos you share on the Internet have been "teased" through Fawkes, then the person in the database who can be recognized by the algorithm will not actually be yours.

According to του Πανεπιστημίου του Σικάγο, το Fawkes είναι 100% επιτυχία έναντι των state-of-the-art face recognition services, such as Microsoft (Azure Face), Amazon () and the Face ++ of the Chinese company Megvii.

The six-member team behind Fawkes, Shawn Shan, Emily Wenger, Jiayun Zhang, Huiying Li, Haitao Zheng and Ben Y. Zhao, published in early 2020 a task for its algorithm. Late last month Fawkes was also released as free software for windows and mac that anyone can download and use. To date it is said to have descended more than 100.000 times.

Fawkes is easy to use and takes a few minutes to process each image and the changes it makes are mostly imperceptible.

But is Fawkes the most general privacy solution? It is doubtful.
For a start, there is the problem of adoption. If you read this article and decide to use Fawkes to hide any photos you upload to social media in the future, you will definitely be in the minority. Face recognition is a concern because it is a trend aimed at the whole society and so the solution should be used by the whole society. If know-how protects the selfies of certain users, it simply creates inequality and discrimination.

Second, many companies that sell face recognition algorithms have been creating face databases for a long time and you cannot retrieve this information retrospectively. "There are billions of unmodified photos on the Internet, all on different social media," Clearview CEO Hoan Ton-That told the Times. In practice, it may be too late to perfect a technology like Fawkes and develop it globally.

Of course, contrary to the above claims, the team behind Fawkes disagrees. They note that although companies like Clearview claim to have billions of photos, that does not mean much, even when they are supposed to recognize hundreds of millions of users. Chances are, Clearview has only a very small number of publicly accessible photos. And if people upload more Fawkes photos in the future, sooner or later the amount of "teased" images will exceed normal.

The Fawkes team admits that in order for their software to make a difference, it needs to be released more widely. They have no plans to build a web application or mobile app, but hope that companies like Facebook will incorporate a technology similar to Fawkes into their platform in the future.

The incorporation of this it would be in the interest of these companies, Zhao says. After all, companies like Facebook don't want people to stop sharing photos, and as long as facial recognition companies are still able to glean the data they need from public images, the use of Fawkes technology is deemed necessary. And while the integration of this technology for now may only have a small effect, for current users, it could help future generations to come, fearlessly subscribe to these platforms.

“Adoption by larger platforms, e.g. Facebook or others, could over time adversely affect Clearview, rendering their technology so inefficient that it will no longer be useful or economically viable as ,” Zhao says.
