Unlocking Apple's Private Cloud Compute: An Analysis of Privacy-Preserving Artificial Intelligence
Researchers have reverse-engineered Apple's Private Cloud Compute (PCC) to analyze its privacy-preserving AI capabilities. While Apple claims PCC does not store user data and keeps inputs unlinkable, the use of compiled binaries without reproducible builds or symbols creates opacity. The study found that the underlying models and interfaces are not publicly accessible, hindering independent evaluation of their accuracy and trustworthiness. AI
