Encrypted communications are the need of the hour, especially if you’re sharing sensitive information with your contacts. Which is why Signal is such an important tool these days. Its end-to-end encryption applies not only to instant messaging, but also to voice and video calls. What’s all the more awesome is the fact that it’s a free and open-source program that works not just on your iPhone or iPad, but also on your Mac devices. Not to mention versions for Android, Windows and Linux available as well.
A testament to Signal’s brilliant encryption capabilities is the fact that whistleblower and privacy advocate Edward Snowden claims to use it every day, while Twitter CEO Jack Dorsey also swears by it. Signal provides total privacy to its users and is replete with tons of features that ensure your conversations and your data is secure from snooping eyes all the time. For users of Apple devices, iMessage is a great tool for messaging and it offers end-to-end encryption as well, but it’s sadly, not cross-platform. So it makes a lot of sense for iPhone, iPad and Mac users to have Signal installed across all their devices. Once you’ve done that, these 10 tips will definitely come in handy.
Blur your pictures
During the Black Lives Matter protests in the US and over the world, the folks over at Signal introduced this neat feature that lets you blur all the faces in your photos before sending them across. It was an important feature for the protests since it not only protected people’s identiy, but also allow them to send photos without leaving an trace as to who is in them.
The company’s founder, Moxie Marlinspike had written in a blog post, “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.”
Now, there are several apps out there that let you blur faces in your photographs but most of them perform their operations on the cloud. This compromises on their security in a big way, as the process may lead the image to stay on the cloud after it has been edited.
Singal’s face blurring happens entirely on your own iPhone, iPad or other iDevice. Just pressing the Blur Faces button while sharing any image from the app identifies all the faces in it and automatically blurs them for you.
