A military prototype smartphone hints at the risks of biometric security

"“Even if the phones are well secured, allowing the vendor to take the data off the device and store it on their servers would be a source of security risk,” said Riana Pfefferkorn, associate director of surveillance and cybersecurity at Stanford University’s Center for Internet and Society. “Obviously this data, if held by a private vendor, would be a target for hacking by America’s enemies. Plus, careless security practices could lead to a data breach, or the data could be compromised due to an insider threat, such as an employee selling it without authorization.”"
