Cloud privacy with trust issues
Encrypted Spaces An architecture for collaborative applications
Private teamwork in the cloud? Commenters say the leaks may be the real plot twist
TLDR: Encrypted Spaces is a research project for shared apps that keep more user data hidden from the server while still letting people collaborate. Commenters weren’t ready to clap yet: some say the leftover clues around usage could still expose people, while others think asking users to verify anything is a non-starter.
A new research project called Encrypted Spaces wants to make online collaboration feel less like handing your diary to a landlord with a spare key. The pitch is simple: let people work together in shared apps while the server stores the data without being able to freely read it. That matters for people handling truly sensitive info, like journalists, activists, patients, and support groups. In theory, it’s a big privacy glow-up for the cloud.
But in the comments, the crowd immediately zoomed past the shiny promise and into the messy fine print. The loudest reaction? “Cool idea, but what can the server still see?” One commenter basically declared that this is the whole ballgame, warning that even if the words themselves are hidden, things like who’s in the group, when they access data, and how often they search could still spill the tea. For the very people this system claims to protect, critics argue that those traces can be just as revealing as the content.
Then came the doom-posting. One skeptic side-eyed the line about users checking cryptographic proofs and asked if that makes the whole thing dead on arrival, comparing it to the famously awkward dream of mainstream PGP key-signing. Ouch. And for the hardcore crypto fans, there was a totally different complaint: this still isn’t magic encrypted computing. One commenter basically shrugged, saying they were hoping for the sci-fi version where servers compute on fully hidden data, and they’re still waiting. In other words: exciting privacy research, but the comments section is already demanding either less leakage, less user burden, or straight-up wizardry.
Key Points
- •The article presents Encrypted Spaces as a research architecture for collaborative applications that keep shared data encrypted while enabling cryptographic verification of server actions.
- •It argues that conventional cloud collaboration tools require users to trust centralized servers with plaintext data, creating risks from breaches, insider access, and compelled disclosure.
- •An encrypted space is defined as a shared persistent data system where the server stores and synchronizes data without being trusted with plaintext, while schemas control what remains encrypted and what can be queried.
- •The design is built from five components: membership state, a verifiable database with an append-only changelog, key management, a key retention system, and application-defined operations.
- •The team is prototyping a sync engine similar in role to Firebase or Supabase, exposing higher-level data structures and a developer-facing SDK for verified reads and writes on encrypted shared data.
