Apple has introduced Private Cloud Compute (PCC), a secure cloud intelligence system for processing AI tasks while preserving privacy. This coincides with the release of new generative AI features called Apple Intelligence. Both on-device features and those using PCC promise privacy protections, with a focus on data security and user privacy.
From the meeting notes, key takeaways include:
Apple has announced the launch of a groundbreaking Private Cloud Compute (PCC) system designed for processing AI tasks in a privacy-preserving manner in the cloud, coinciding with the arrival of new generative AI features collectively dubbed Apple Intelligence.
PCC leverages stateless computation to offload complex requests requiring more processing power to the cloud while ensuring data is never retained or exposed to any third-party, including Apple.
The architecture underpinning PCC features a custom-built server node that brings together Apple silicon, Secure Enclave, and Secure Boot to run Large Language Model (LLM) inference workloads with a narrow attack surface and privacy measures.
PCC requests are routed through an Oblivious HTTP (OHTTP) relay operated by an independent party to conceal request origins, and Apple plans to publish every production PCC software image for independent binary inspection, ensuring cryptographic privacy.
Apple Intelligence, expected to launch later in the fall, will be limited to specific devices and language settings, and other new privacy features include app locking, contact sharing options, and Wi-Fi address rotation to minimize tracking.
Additionally, MacRumors reports that Apple has introduced a Passwords app with features for upgrading existing accounts to passkeys and a refreshed Privacy & Security section in Settings.
