Edward Snowden wants to build an iPhone case that will tell you if the NSA is listening

Edward Snowden wants you to know at all times whether the NSA is keeping tabs on your iPhone. Along with Andrew Huang, his coauthor and fellow hacker, Snowden presented his research on phone "hardware introspection" at MIT, which aims to give users the ability to see whether their phone is sending out secret signals to an intelligence agency. "This work aims to give journalists the tools to know when their smart phones are tracking or disclosing their location when the devices are supposed to be in airplane mode," the pair wrote in their technical paper.
