Although Apple has tried to allay security concerns around the iPhone 5S Touch ID fingerprint scanner (shown above), U.S. Sen. Al Franken is not satisfied.The humorist-turned-politician sent an open letter to Apple CEO Tim Cook with a dozen questions on the privacy implications of Touch ID. The junior senator from Minnesota wrote that he hopes to "establish a public record" of how Apple has addressed these issues."[W]hile Apple's new fingerprint reader, Touch ID, may improve certain aspects of mobile security, it also raises substantial privacy questions for Apple and for anyone who may use your products," Franken wrote, noting that he personally owns an iPhone.Among the questions Franken raises:Does Apple have plans to let third-party apps access the Touch ID system or its data?
