Telegram Adds DRM Lock for Content in Latest Update

Encrypted chat app Telegram has been updated with new features, including DRM for certain content.

With this update, we’re helping creators protect the content they publish on Telegram and ensure that it is available only for their intended audience.

Group and Channel owners who want to keep their content members-only can restrict message forwarding from their chat, which also prevents screenshots and limits the ability to save media from posts.

Secure Chat App ‘Signal’ Announces Default Disappearing Messages

Signal, a messaging app that uses end-to-end encryption, introduced a feature to let you have all of your messages disappear by default.

Until now, disappearing messages had to be enabled on a per-conversation basis, but for those who want to take ephemerality to the fullest, Signal now supports the ability to preconfigure all conversations you initiate with a default timer.

We’ve also added the ability to set custom timer durations on your conversations, so that some content can be gone in 60 seconds and others can exist for 18 minutes or 4 weeks.

Link Previews in Chat Apps Could Leak Your IP Address

Security researchers found that link previews in chat apps could expose data like IP addresses if not implemented properly. Or they could be downloading as much as gigabytes of data in the background. They tested a variety of different messaging apps, and iPhone users will be relieved to know that iMessage didn’t experience any of these security leaks.

We think there’s one big takeaway here for developers: Whenever you’re building a new feature, always keep in mind what sort of privacy and security implications it may have, especially if this feature is going to be used by thousands or even millions of people around the world.

Private Messenger ‘Signal’ Now Automatically Blurs Faces

Private messenger app Signal added a feature that lets it automatically blur faces in your images.

Thousands of people are protesting against police brutality and to support the Black Lives Matters cause. If you are a part of the protests, you might post photos of the demonstration around you on social media or send them to your friends — and that’s not entirely safe, because it could help identify people there and put them in danger.

A great feature. I’ve been trying to create a shortcut that can obfuscate faces.

It’s Time for Encrypted Messaging app Signal to go Mainstream

Signal creator Moxie Marlinspike is growing the Signal Foundation and adding new features to the app thanks to money from WhatsApp cofounder Brian Acton.

Since then, Marlinspike’s nonprofit has put Acton’s millions—and his experience building an app with billions of users—to work. After years of scraping by with just three overworked full-time staffers, the Signal Foundation now has 20 employees. For years a bare-bones texting and calling app, Signal has increasingly become a fully featured, mainstream communications platform. With its new coding muscle, it has rolled out features at a breakneck speed…

I wish I could use Signal but none of my friends use it.

New Messaging Standard RCS Won't Have Encryption

Everyone is talking about a new messaging standard the Big Four carriers have agreed upon. It’s called RCS and it’s meant to replace SMS. But your RCS conversations won’t be end-to-end encrypted.

The CCMI neatly fixes both the first and the second problem. Garland says the carriers believe there are some implementation issues with the Universal Profile that the CCMI can address more elegantly, but it will follow the standard to ensure interoperability.

As for encryption, Garland wouldn’t commit. He emphasizes that the CCMI intends to make sure that the chats are “private” and that the app it’s making is “an experience [customers] can trust.”

Having Apple join the project would certainly legitimize RCS, but if it doesn’t have encryption I don’t think Apple will partake.

It's Now Easier to Delete Telegram Messages

With a new “delete everywhere” feature it’s now easier than ever to delete Telegram messages and erase your chat history.

The new ‘nuclear option’ delete feature allows a user to selectively delete their own messages and/or messages sent by any/all others in the chat. They don’t even have to have composed the original message or begun the thread to do so. They can just decide it’s time.
