Abstract
A technique for secured personal identification numbers which cannot be readily detected by either observation or repeated trial attempts is disclosed. The secured personal identification number maintains the dual level security of a personal identification number or password without adding substantial complexity or an undesirable reduction in security. Moreover, the secured personal identification number of the present invention is readily applicable to any type of account which is accessed by entry of an account number and a personal identification number or password.
