<p>A system for identifying an individual is determined either by assigning that person a unique identification number based on a distinctive characteristic possessed by that person (e.g. voice analysis, finger print, facial scan, DNA etc.), or by means of verifying some unique digital 'signature' representation assigned to that person. The unique ID number or digital signature may then be used in a variety of functions to enhance both the security and convenience of conducting electronic transactions. The system may provide a means for creating unique PIN numbers for use as a preliminary or secondary identification means, and/or a means for generating unique tone codes for use in personal identification via telephone or modem. Further, security of online transactions may be greatly improved by placing access key information in a medium outside the computer host or client. The system further provides a means that facilitates a user's ability to change codes or methods of generating codes instantly, without having to contact their bank, credit card compagny, etc.</p> |
