ENHANCED PIN-BASED SECURITY SYSTEM

摘要

An enhanced system for the security of PIN-based security systems is described wherein the user is provided with a PIN modifier which is specific to a particular transaction. After a successful transaction, the user is provided with a new PIN modifier to use for the next transaction, preferably through the use of an Internet enabled cellular telephone. In order to use the system and gain access to the restricted resources, the user must have the account number, the standard PIN number, and additionally know the PIN number modifier. As a result, increased security for PIN number-based security systems is enhanced.
