The Chicago Tribune recently wrote a story about a company called “Pay by Touch.” The company registers and identifies you by phone number and finger print. Then, a special algorithm is used to prevent people from duplicating your fingerprint or pretending to be you. The marketplace will decide whether this method works, but Clark has no problem with ideas like this. There will be problems and attempts to crack this kind of system. It also has a slight creep factor. But, we need to keep coming up with new ways of protecting our information.
