As Meta’s first-ever generative AI conference gets underway, the company is also previewing a significant update on its plans to bring AI features to WhatsApp chats. Buried in its LlamaCon updates, the company shared that it’s working on something called “Private Processing,” which will allow users to take advantage of generative AI capabilities within WhatsApp without eroding its privacy features.
According to Meta, Private Processing is an “optional capability” that will enable people to “leverage AI capabilities for things like summarizing unread messages or refining them, while keeping messages private.” WhatsApp, of course, is known for its strong privacy protections and end-to-end encryption. That would seem incompatible with cloud-based AI features like Meta AI. But Private Processing will essentially allow Meta to do both.
Meta has shared more details about how it will accomplish this over on its engineering blog but, as Wired points out, it’s a similar model as Apple’s Private Cloud Compute (which allows the iPhone maker to implement Apple AI without sending all your data to the cloud). Here’s how Meta describes its approach.
We’re excited to share an initial overview of Private Processing, a new technology we’ve built to support people’s needs and aspirations to leverage AI in a secure and privacy-preserving way. This confidential computing infrastructure, built on top of a Trusted Execution Environment (TEE), will make it possible for people to direct AI to process their requests — like summarizing unread WhatsApp threads or getting writing suggestions — in our secure and private cloud environment. In other words, Private Processing will allow users to leverage powerful AI features, while preserving WhatsApp’s core privacy promise, ensuring no one except you and the people you’re talking to can access or share your personal messages, not even Meta or WhatsApp.
The company seems well-aware such a plan will likely be met with skepticism. WhatsApp is regularly targeted by bad actors as it is. To address inevitable concerns from the security community, the company says it will allow security researchers and others to audit Private Processing, and will make the technology part of its bug bounty program that rewards people who find security vulnerabilities in its services.
It’s not clear when generative AI features may actually be available in WhatsApp chats — the company describes its announcement today as merely a “first look” at the technology — but it does note that Private Processing and “similar infrastructure” could have use cases beyond its messaging app.
