AUTHENTICATION UTILIZING A DYNAMIC PASSCODE FROM A USER-DEFINED FORMULA BASED ON A CHANGING PARAMETER VALUE

摘要

An authentication system utilizes dynamic passcode from a user-defined formula based on a changing parameter value. The changing parameter is publicly accessible through the communication network and has a current value that is periodically updated, such as a stock value, temperature at a specific location, or a sports score. The user-defined formula is based on the changing parameter in order to derive a passcode which authenticates a user to an associated user account. As referred to herein, the user-defined formula is a mathematical formula in which the changing parameter is one variable (e.g., [changing parameter value] + 1). Some formulas include more than one changing parameter.
