"Meta" Unveils a New WhatsApp Feature to Protect the Privacy of AI Conversations

The company "Meta" announced the launch of a new feature in the WhatsApp application under the name "Private Processing", which aims to provide a safe and private interactive environment when using its AI assistant, Meta AI.

Meta confirmed that this feature will be entirely optional, and it is expected to begin reaching users in the coming weeks. The company also stressed that no one — including Meta, WhatsApp, or any third party — will be able to see the content of these interactions.

The "Private Processing" feature aims to enable users to direct the AI assistant to perform tasks such as summarizing conversations or answering queries within secured sessions. All messages and content are automatically deleted as soon as the session ends, preventing any malicious party from accessing them even in the event of a system breach.

Through this step, Meta seeks to reduce the opportunities for targeting users through cyberattacks, without needing to breach the infrastructure itself. The company also announced that it will allow independent parties to review the feature's performance and verify its compliance with privacy and security standards.

In the context of enhancing transparency, Meta confirmed the inclusion of this system in the bug bounty program, along with a promise to publish a detailed engineering paper explaining the security mechanisms used, coinciding with the approaching official launch date.

According to Meta

According to what Meta clarified, requests made through the "Private Processing" feature will be routed through an external provider using the OHTTP protocol (Oblivious HTTP), which works to hide the user's IP address, in a step similar to what Apple offers through the Private Cloud Compute feature.

Despite this similarity, technical experts pointed to a fundamental difference between the two approaches; all AI requests in WhatsApp are processed inside Meta's servers, and activating the "Private Processing" feature requires a manual action from the user. In Apple's case, however, processing is done by default on the local device, and data is only sent to servers when absolutely necessary.

This feature is part of a broader strategy adopted by Meta, aimed at strengthening user trust in AI technologies, while fully adhering to the principles of privacy protection and data security amid the rapid expansion in the use of these tools within messaging applications.

A Strategic Step Toward AI-Powered Privacy

The "Private Processing" feature comes as part of Meta's efforts to redefine how users interact with AI technologies within messaging applications, especially amid growing concerns about data collection and analysis for commercial or security purposes.

Unlike traditional AI models that rely on recording interactions to improve performance, Meta follows in this feature a model closer to the "No Retention Model" philosophy, where data is deleted immediately after the session ends without being stored or used to train models in the future.

What is the OHTTP Protocol? And Why Does It Matter?

Meta's reliance on the OHTTP (Oblivious HTTP) protocol is considered a notable development, as it allows separating the user's identity from the content of the sent request, so that no party — not even Meta itself — can link the user's identity to what they do within the session.
This protocol allows requests to be passed through an external intermediary that encrypts the data before sending it to the servers, providing an additional layer of privacy that does not rely solely on end-to-end encryption.

Privacy as a Competitive Advantage

Through this step, Meta is attempting to keep pace with the growing trend in the technology industry toward making privacy a core competitive advantage. While Apple was the pioneer in integrating local security within its devices, Meta relies on a combination of transparency, user options, and external encryption to deliver a safe interactive experience within a cloud environment.

Challenges and Opportunities

Despite the technical advantages, the step is not without potential challenges, most notably:

  • The need to raise awareness among users about the necessity of manually activating the feature.

  • Addressing some users' concerns about full reliance on Meta's servers for processing.

  • Maintaining fast and efficient performance of sessions despite multi-layer encryption.

Nevertheless, this initiative is part of a broader shift in Meta's philosophy, which is attempting to provide powerful AI tools without sacrificing user privacy — an equation that was not easy to achieve previously.

The Future of AI in Messaging

This step is expected to establish a new phase of AI use in messaging applications, where AI-powered conversations transform into daily productivity tools, supported by secure and open-to-review infrastructure, as Meta promised.
