Meta is enhancing WhatsApp's functionality with an AI-driven feature called 'Private Processing,' designed to operate in a secure environment. This new approach reassures around 2.78 billion users that their data remains private while utilizing AI capabilities like summarizing chat threads and generating writing suggestions. By leveraging a Trusted Execution Environment (TEE) for AI processing, Meta aims to preserve user privacy, ensuring personal messages are not accessible to anyone outside the user and their contacts, including Meta and WhatsApp itself.
Using confidential computing infrastructure, built on top of a Trusted Execution Environment (TEE), [Private Processing] 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.
Data shared to Private Processing is processed in an environment which does not make it available to any other system. This protection is further upheld by encrypting data end-to-end between the client and the Private Processing application, so that only Private Processing, and no one in between - including Meta, WhatsApp, or any third-party relay - can access the data. To prevent possible user data leakage, only limited service reliability logs are permitted to leave the boundaries of CVM.
