German hacking group Chaos Computer Club says its biometrics hacking team has discovered how to bypass the biometric security of Apple’s TouchID fingerprint authentication through a simple method based on a rubbery duplicate of a fingerprint the group devised. The gummy fingerprint trick is one that is well-known and has been used before to raise questions about how uncrackable some fingerprint-based bi-biometrics might be. The club says iPhone users should avoid protecting sensitive data with fingerprint bi-security because it can be easily faked.”]
