Tech that hangs on your every word raises privacy questions

Apple's digital assistant gets an upgrade in the newest version of iOS. Users will no longer have to press a button to summon Siri, instead they can set their smartphones to constantly listen to their conversations -- just waiting for an opportunity to give directions or tell a joke. But privacy advocates worry that this type of technology could become a hazard that users aren't prepared for. "When you enter the realm of always-on devices, there are real privacy implications that need to be addressed," said Marc Rotenberg, executive director of the Electronic Privacy Information Center (EPIC). "Even if the user of the device consents, it doesn't necessarily mean other people who are there consent to the routine recording of everything they might say."
