How wil private cloud computing work?

Private cloud computing, as presented at WWDC, is designed to process AI privately while ensuring user data remains secure. Here are the key points:

1. Privacy and Security: Private cloud compute runs on a new OS using a hardened subset of iOS, omitting features not necessary for AI processing to mitigate privacy risks. It includes a full machine learning stack and is based on Apple silicon, ensuring a secure foundation.

2. Encryption and Verification: It starts with the secure enclave to protect encryption keys, secure boot to ensure the OS is signed and verified, and a trusted execution monitor to ensure only signed code runs. User devices establish end-to-end encrypted connections with the private cloud compute cluster, ensuring data is not retained after processing and is never accessible to Apple.

3. Transparency and Inspection: Apple commits to making virtual images of every production build of private cloud compute publicly available for inspection by security researchers. This ensures transparency and allows verification of Apple's security claims.

4. Advanced Security Architecture: The system uses strong cryptographic attestation mechanisms to ensure that user devices only communicate with clusters running a signed build that has been publicly logged for inspection.
