Apple is working on what would be a significant and perhaps necessary overhaul for its Siri platform.
According to a patent application unearthed this week, the company is teaching Siri to respond only to the voice of her master.
It would also enable users to customise a wake word to replace Hey Siri, adding an additional level of security.

Currently Siri will respond to just about anyone whether the device is locked or unlocked.
So, if you leave you phone unattended, it’s still possible for unauthorised parties to access some of the functionality by pressing the home button or using the “Hey Siri” command, if enabled.
The patent was initially filed around this time last year, so it’s possible that Apple might be prepared to integrate this within iOS 11 and the next versions of tvOS, watchOS and macOS.
Indeed, voice biometrics are certainly an untapped area for personal assistants like Siri, Alexa and Cortana.
A voice signature isn’t as unique or secure as a fingerprint or an iris scanner, so the implementation will doubtless be tricky.
