Signal Encrypted Messenger Rolling Out New Face-Blurring Tool for Shared Images

by

Encrypted messaging app Signal is rolling out a new face-blurring feature that automatically locates and blurs faces in images shared over the platform.


In a blog post announcing the update, Signal co-founder Moxie Marlinspike explained that the tool was a response to a surge in traffic, spurred by ongoing protests around the world against racism and poice brutality.

Many of the people and groups who are organizing for that change are using Signal to communicate, and we're working hard to keep up with the increased traffic. We've also been working to figure out additional ways we can support everyone in the street right now.

One immediate thing seems clear: 2020 is a pretty good year to cover your face.

The latest version of Signal for Android and iOS introduces a new blur feature in the image editor that can help protect the privacy of the people in the photos you share. Now it's easy to give every face a hiding place, or draw a fuzzy trace over something you want to erase. Simply tap on the new blur tool icon to get started.

According to Marlinspike, all processing involved in the new blur feature happens locally on the device to maintain privacy. He also cautions that the feature isn't perfect, and won't detect every face all of the time. To compensate for these flaws, Signal's image editor also includes an option to manually obscure faces and other areas of a photo with a blur brush.


Since May 25, Signal has been setting daily download records in the U.S., according to Apptopia (via Recode). The encrypted chat app was the eighth most downloaded social networking app on Tuesday, for example, and ranked around the top 100 for all apps.

Signal Private Messenger is a free download [Direct Link] for iPhone and iPad available on the App Store.

It’s interesting that a simple image editing feature — something easily achieved in photoshop and many other apps — requires a political warning at the bottom of the post.

And then lo and behold, immediately there are really dumb comments about how bad this is or how it is no use. It can’t be both.

But image editing features are useful. And privacy is important.

You may not like people currently wanting privacy, but one day it might be you.

New features are good. People can choose whether to use them or not. If it is of no use to you then fine. If it is helpful to others then great.

Rioters, looters, and vandals don’t deserve an iota of privacy. Expose those criminals, I say.

Haha how will this help? To shield criminals and Antifa agitators?


Yeah I’m sure the one person who uses this will really make the difference in an era of surveillance.

To shield peaceful protesters from people (like you?) who would assume they're criminals and potentially go after them or their families.

What a nice way to help Antifa.

The more that can be done to help people who are anti-FASCISM, the better. It boggles my mind that US president seemingly succeeded in making fascists / nazis seem normal and victims.

Is providing cover to people breaking the law now a virtue worthy of signalling?

(pun intended)

Are peaceful protesters seriously worried about being identified when there are drones in the sky and cameras on every corner and almost everyone supports the protests? Why do people need to shield their identities in public?

I'm really confused why this feature is needed right now / worthy of a "look at us" blog post.
