The new open-source project could serve as the basis for a future of apps with features as complex as Slack, Discord, or Google Docs--but with added protection against surveillance. End-to-end encryption, in which data is encoded so that only users on either "end" of a conversation can decrypt their communications--and not the server that relays that information or any other interloper--has become the standard for modern privacy on the internet. But its very name suggests a kind of simple pipe with two openings. The metaphor, and often the encryption technology that has enabled that model, doesn't fit neatly onto the world of Slack, Discord, Google Docs, and the other multiuser, complex, collaborative software where people now live and work. So one group of cryptographers has built what they describe as the foundation for a new generation of end-to-end encrypted apps, with a new metaphor: Instead of a mere pipe, they want to create "spaces" where users can hold group conversations, host information on a server, collectively make changes to it, invite in new collaborators or kick them out, all while maintaining the same strong encryption protections that prevent the server or network eavesdroppers from accessing their data.

Proton's Lumo AI chatbot now has an encrypted space for your projects Lumo 1.3 is now available to all users. Proton launches Projects within Lumo. Proton's latest update for Lumo, its privacy-focused chatbot, introduces a feature called Projects. It's a dedicated and encrypted space for tasks that you know you'll access again and again over an extended period of time, such as papers you'll have to work on the whole semester or plans for a big trip you're taking later this year. Lumo will remember and keep all the information and all the files you upload for every project you create. Any document you upload or resources you add to the chat will sync across devices, so you don't have to repeat yourself every time you access a task.
