Image transformation tightens biometric security
Finger prints, facial recognition, iris scanning. Biometrics are seemingly the way forward in security. However, for biometrics to function, information on whatever is being scanned needs to be stored, be it the unique parts of a finger print, or features of a face. If a hacker can obtain that information, they can construct a means of entry that meets the criteria in the biometric database for a particular security system. Researchers have devised a way to thwart this potential security issue, by distorting an image before recording it.

While a standard biometric can't be torn up and reissued like a credit card or password -- since it's based on unchanging aspects of a person's physical appearance -- distortion makes that possible. A bank or an office building that had its biometrics compromised could register new ones simply by changing the way it transforms images.
Unique distortions would make it hard for hackers, just don't ask for a printout or you may be offended.
