Apple’s introduction of the iPhone in 2007 kicked off a revolution in personal informationsharing.
With each new iPhone improvement it’s easier to tell the world where we are, what we’redoing and who we’re doing it with.
A bit ironic then that Apple is leading the charge to reclaim privacy.
Newer versions of iOS emphasize encryption,to the point where Apple says it won’t be able tounlock its customers’ phones even if law enforcement orders them to do so.
Some of the latest Android devices likewise offer encryption.
But Apple recently raised the stakes
the company just bought two start–ups whose artificial intelligence technology should giveiPhones greater independence from Apple’s back–end server farms, aka “the cloud.”
And like on Battlestar Gallactica, if you avoid the network, it’s a lot harder for you to gethacked.
The first start–up is called Perceptio.
Its deep–learning software essentially models the human brain’s ability to match patterns.
iPhones could then crunch ever–larger amounts of data themselves without calling the cloud forhelp.
The second start–up, called VocalIQ, makes software that should help Siri better remember itsconversations with iPhone users.
Instead of having to go back to the Web with every request, the voice–controlled digitalassistant would sometimes be able to dip into its own memory for answers.
That ability might also help Siri sound more natural and put an end to its awkward,prepackaged responses.
