"Biometric systems have one particularly critical vulnerability: how do you replace your finger if a hacker figures out how to duplicate it? IBM's idea for navigating that obstacle is to construct a kind of technological screen separating a user's actual biological identification information from the records stored in profile databases. The company is developing software to transform biometric data such as fingerprints into distorted models that still preserve enough actual identification markers to make the distortion repeatable."
