On Wednesday, WhatsApp announced the rollout of a new AI chat feature called Incognito Chat, designed to provide users with a secure means of communicating with Meta AI while ensuring that Meta itself cannot access the content of these interactions. This initiative hinges on WhatsApp’s Private Processing framework, which was introduced last year and serves as the foundation for existing AI functionalities, such as message summarization and composition.
The primary objective of Incognito Chat is to maintain WhatsApp’s dedication to end-to-end encryption, a security measure that allows only the participants of a conversation to view messages or hear calls. In the current landscape, many generative AI services offer incognito modes; however, these typically only anonymize user queries rather than fully shield them from the service provider. With Incognito Chat, WhatsApp’s visibility is limited to knowing that a user has engaged with the feature, as stated by Meta.
Meta aims to promote transparency by inviting external audits and vulnerability assessments of its Private Processing system. The Incognito Chat feature will undergo rigorous expert scrutiny to validate the robustness of the underlying code. Nevertheless, using this service still requires a base level of trust in Meta, akin to the inherent trust involved in standard WhatsApp communications.
According to Will Cathcart, head of WhatsApp, a significant aspect of the platform’s development revolves around enabling users to benefit from privacy-focused solutions that remain user-friendly. He elucidated this challenge, emphasizing the discrepancy between the ideal scenario of local device processing and the computational demands of more sophisticated AI models. Incognito Chat represents a compromise, likened to an expansive AI processing unit that lacks personal access credentials.
Conversations via Incognito Chat are inherently ephemeral, erasing themselves after the session concludes. Although currently limited to text interactions, Cathcart indicated that WhatsApp is exploring options within Private Processing to allow users the ability to preserve chat histories. Future updates promise to include support for image processing and voice recognition, with efforts underway to minimize latency to optimize usability within the confines of a secure cloud framework.
Mark Zuckerberg, CEO of Meta, reinforced the privacy commitment associated with Incognito Chat in a public post, noting that interactions are conducted within a Trusted Execution Environment, ensuring that messages are not accessible to Meta. The design promotes the transient nature of conversations, contrasting sharply with other AI systems where logs often remain stored on external servers for extended periods.
Moreover, Meta is also introducing Incognito Chat as a feature within the Meta AI application, expanding user options for AI interactions.
In conjunction with the launch of Incognito Chat, an additional feature dubbed “Side Chat with Meta AI” has been unveiled. This functionality allows users to privately engage with Meta AI while discussing topics with others, facilitating requests for recommendations without compromising personal information or interests shared within the group.
