Abstract: Methods and apparatus are provided for defending against telephone-based robotic attacks An interactive voice response method is provided for presenting a menu having one or more menu options to a caller. The method comprises the steps of obtaining a script to present to the caller, the script including the one or more menu options; permuting one or more characteristics of at least one of the one or more menu options; and presenting the permuted menu to the caller. The permutation may comprise, for example, adding one or more additional menu options to the menu; varying a selection number associated with the at least one menu option; varying an order of at least a plurality of the menu options; or varying a wording or pronunciation of one or more menu options.

Abstract: Methods and apparatus are provided fox defending against telephone-based robotic attacks. An interactive voice response method is provided for presenting a menu having one or more menu options to a caller associated with a call. The method comprises the steps of obtaining a script to present to the caller, the script including the one or more menu options; combining at least one of the one or more menu options with a background audio signal, wherein the background audio signal is selected based on a context of the call; and presenting the combination of the at least one of the one or more menu options and the background audio signal to the caller. The context of the call includes comprises one or more of an identity of a called party associated with the call and a time period of the call. The background audio signal can optionally be obtained from a library of background signals.

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.
