Apple's security research blog details Secure Exclaves, a purpose-built architecture in Apple silicon for ambient sensing (powering features like HomeView's six-person recognition and "Hey Siri"). Key points: sensor streams are reduced to minimal signals (never recorded or exposed to the OS), raw data is discarded after processing, and a tamper-resistant signal replaces LED indicators to distinguish background sensing from active recording. The post hints at Apple's plans for secure AI wearables and ambient computing hardware.
