We are inspired by the possibilities of AI to help people be more creative, productive, and stay closely connected on WhatsApp, so we set out to build a new technology that allows our users around …
Because we set out to meet these high-security requirements, our work to build Private Processing began with developing a threat model to help us identify potential attack vectors and vulnerabilities that could compromise the confidentiality, integrity, or availability of user data. Observability and debuggability remains a challenge in highly secure environments as they can be at odds with the goal of confidential computing, potentially exposing side channels to identify data and in the worst case accidentally leaking messages themselves. Private Processing utilizes CPU-based confidential virtualization technologies which allow attestation of software based in a hardware root of trust to guarantee the security of the system prior to each client-server connection.
