CLOUD COMPUTING
The Apple Watch is one of the most popular personal edge computers in the world. While the iPhone and iCloud are central to its ecosystem, the watch’ s most critical functions are performed locally for two simple reasons: speed and privacy. When the watch detects a hard fall or a car crash, for example, it must react instantly – it cannot afford a network delay to ask a cloud server for permission to call emergency services. Likewise, sensitive health data like your heart-rate rhythm( EKG) is processed directly on the S-series chip. This philosophy is central to Apple’ s new AI features.
“ We’ ve extended iPhone’ s industryleading security to the cloud, with what we believe is the most advanced security architecture ever deployed for cloud AI at scale,” Apple’ s Senior Vice President of Software Engineering Craig Federighi says.“ Private Cloud Compute uses your data only to fulfill your request and never stores it, making sure it’ s never accessible to anyone, including Apple. And we’ ve designed the system so that independent experts can verify these protections.”
This hybrid approach – which starts with on-device processing – means personal data stays secure at the edge, on your wrist. technologymagazine. com 141
