When you take a picture through Signal and select the Blur option in the toolbar, the app will automatically detect any faces it spots in your image. If it misses any, users can simply blur out faces by hand, or blur any other features they want to hide. All processing is done on-device, meaning uncensored images never leave the user’s phone.
It’s not foolproof, as the article explains, but it’s a good initiative. Now may also be the time to use non-USA based messaging apps.
