A system and method that provides a user with the ability to transmit confidential information to an IVR system in a secure manner includes invoking an interactive voice response (IVR) routine, the IVR routine determining each of the digits in the sequence by making successive queries and/or digit guesses. A user of the voice communication device need only make an affirmative response or a negative response to each query or digit quess. Once determined, each of the digits in the sequence is sent to the destination system. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.

1. A non-transitory computer-readable storage medium encoded with a computer program for securely transmitting a sequence of digits across a network from a voice communication device to a destination system, when executed, the computer program operable to: during a communication session, invoke an interactive voice response (IVR) routine for sequentially determining the digits in the sequence, for each digit the IVR routine making at least one digit guess or a query, a response by a user of the voice communication device to the at least one digit guess or the query indicating either a correct digit, an incorrect digit, or information to a digit guess or inquiry that narrows a range of possible remaining choices, the response being in a form that does not explicitly reveal a correct one of the digits in the sequence via spoken words or keypad entry to an eavesdropper who is able to discern the response, but not the at least one digit guess or the query of the IVR routine, the information being used by the IVR system as a basis for making at least one successive digit guess or another query until the correct digit has been determined; andonce determined, send the sequence of digits to the destination system. 2. The non-transitory computer-readable storage medium of claim 1 wherein the digits in the sequence are sent to the destination system one at a time, each digit being sent once it has been determined by the IVR routine. 3. The non-transitory computer-readable storage medium of claim 1 wherein the information comprises a spoken construct. 4. The non-transitory computer-readable storage medium of claim 1 wherein the response by the user is a verbal response. 5. The non-transitory computer-readable storage medium of claim 4 herein the verbal response is either affirmative or negative. 6. The non-transitory computer-readable storage medium of claim 1 wherein the response by the user is a non-digit keypad button response. 7. The non-transitory computer-readable storage medium of claim 1 wherein the at least one digit guess or the query is randomly generated. 8. A non-transitory computer-readable storage medium encoded with a computer program for securely transmitting a sequence of digits across a network from a voice communication device to a destination system, when executed, the computer program operable to: during a communication session, invoke an interactive voice response (IVR) routine that includes successive queries or digit guesses for determining each of the digits in the sequence, the IVR routine being constructed such that a user of the voice communication device need only make an affirmative response or a negative response to each query or digit guess, the affirmative response or the negative response being in a form that does not explicitly reveal a correct one of the digits in the sequence via spoken words or keypad entry to an eavesdropper who is able to discern the affirmative or the negative response, but not the successive queries or digit guesses of the IVR routine; andonce determined, send one or more of the digits to the destination system. 9. The non-transitory compute-readable storage medium of claim 8 wherein the digits are sent to the destination system one at a time, each digit being sent once it has been determined by the IVR routine. 10. The non-transitory computer-readable storage medium of claim 8 wherein the computer program, when executed, is further operable to respond to a spoken construct of the user. 11. The non-transitory computer-readable storage medium of claim 8 wherein the affirmative response and the negative response are both verbal responses. 12. The non-transitory computer-readable storage medium of claim 8 wherein the affirmative response comprises a first non-digit keypad button response and the negative response comprises a second non-digit keypad button response. 13. A processor-implemented method of securely transmitting a sequence of digits across a network from a voice communication device to a destination system, the method comprising: invoking an interactive voice response (IVR) routine, the IVR routine:determining each of the digits in the sequence by making successive queries or digit guesses, wherein a user of the voice communication device need only make an affirmative response or a negative response to each query or digit guess, the affirmative response or the negative response being in a form that does not explicitly reveal a correct one of the digits in the sequence via spoken words or keypad entry to an eavesdropper who is able to discern the affirmative or the negative response, but not the successive queries or digit guesses of the IVR routine; andonce determined, sending each of the digits in the sequence to the destination system. 14. The processor-implemented method of claim 13 wherein the method further comprises responding, by the IVR routine, to a spoken construct of the user, the IVR routine making a new query or digit guess based on the spoken construct. 15. The processor-implemented method of claim 13 wherein invoking the IVR routine comprises speaking a trigger word into the voice communication device. 16. The processor-implemented method of claim 13 wherein the method further comprises randomly requesting that the user speak certain dummy digits. 17. The processor-implemented method of claim 13 wherein the affirmative and the negative responses both comprise verbal responses. 18. The processor-implemented method of claim 13 wherein the affirmative response comprises a first non-digit keypad button response and the negative response comprises a second non-digit keypad button response.
