Apple’s Siri personal assistant in the iPhone and iPad remains a risk to businesses, experts say. Apple told Wired last week that it keeps Siri voice clips for up to two years. IBM banned employees from using Siri as part of a new set of bring-your-own-device (BYOD) policies in 2012. Organizations have no way on their own to track or archive the data or to ensure it remains private. The number of companies that allow employees to use their own devices has jumped from 10% in 2008 to 80% last year.”]
