The data stored on Signal is encrypted and cannot be accessed by your phone's operating system either. The contact book is preserved as a you switch from one phone to the next and you can keep your Signal contacts separate from your smartphone's normal contacts.Īlso Read: Telegram vs WhatsApp: The battle to keep your chats super private The encrypted contact storing would also use a new system called "secure value recovery" which lets you create a contact book of Signal users which is stored - encrypted - on Signal's servers. It's just groups, and it works like we expect groups to work," Marlinspike said. "It required coming up with some innovations in the world of cryptography.
It's designed in partnership with Microsoft Research where an app uses 'anonymous credentials' for gatekeeping user entry into a group".
Signal's group chat changes "will allow administrators to add and remove people from groups without a Signal server ever being aware of that group's members. This is something for everyone in the world," Acton said. "This is not just for hyperparanoid security researchers, but for the masses. These features we have just talked about are not exactly privacy-conscious features that Signal spoke about, but they are 'enrichment features' that work for users who are more focused on usage and not so much the privacy factor.
SIGNAL APP SECURE SOFTWARE
"The major transition Signal has undergone is from a three-person small effort to something that is now a serious project with the capacity to do what is required to build software in the world today," Moxie Marlinspike, creator of Signal and co-founder of the Signal Foundation, said. Signal supports images and videos that disappear after they have been viewed (like Snapchat and Instagram), stickers, emojis etc and it has also been announced that it will "trial support for storing encrypted contact details in the cloud" and will also offer a new system for group messages. Keeping the privacy of users in mind, it uses 'stickers packs' that are encrypted with pack keys".Īlso Read: WhatsApp's end-to-end encryption useless, says Telegram CEO For example, "adding stickers to the Signal messaging app is not the same as adding the feature to any other messaging app. Three latest updates in Signal include support for iPad, an image/video disappearing feature after viewing and customisable stickers.Īdding a feature in Signal is complicated as the app does not compromise with security. The core users of the app are cybersecurity nerds, privacy experts and activists for now but going by the current political climate, we see this circle expanding. Signal CEO Moxie Marlinspike said that Signal Messenger is going through several changes and he has created the app to make "encrypted communication easy so that anyone can use it".
