Apple may be working on multi-user support for Siri

Today, Apple Insider reported that Apple had been granted a patent that would allow a voice recognition system to identify a user based on their speech and perform tasks based on who is speaking. This could be the framework for Apple to offer multi-user support with Siri. Right now, Siri will answer to whomever is speaking. This system would allow a user to set up profiles on their phone, and Siri could match the voice of whoever is speaking to the onboard profiles and customize responses. For example, a phone's primary user could restrict calendar or message access to protect information they'd like to keep private.
