ABSTRACT:
Methods and apparatus are provided for defending against telephone-based robotic attacks. An interactive voice response method is disclosed, comprising the steps of obtaining a script to present to a caller, the script including at least one menu option having at least one personal code; generating a random number for the personal code; and presenting the at least one menu option with the generated random number to the caller. The step of generating a random number for the personal code is optionally responsive to receipt of the call. The method is optionally performed only if one or more predefined criteria defining an attack are satisfied. The disclosed IVR system can optionally monitor the caller response to determine whether the caller enters the generated random number.
