Abstract

A process, apparatus and system are disclosed for verifying the authenticity of a user before providing the user with a desired service. The process involves first receiving a request from the user. Next, a question set is fetched corresponding to the user. The question set concerns information of a private nature that someone with rightful access to the desired services should know. The question set has at least one question and a possible answer or list of possible answers corresponding to the question. The question is then transmitted to the user along with the possible answer(s). After receiving a response from the user, a record is made whether the response correctly identified the possible answer as being correct or not. Finally, after the number of questions transmitted to the user reaches a predetermined number, a determination is made whether the number of incorrect responses exceeds a certain limit. If the number of incorrect responses exceeds the certain limit, then the user is refused the desired service. Otherwise, the user is provided with the desired service.

Claims

1. A method of ascertaining the authenticity of a user using an automated computer system before providing said user with a desired service, said method comprising performing the following steps using an automated computer system:

a. receiving a request for a desired service from said user;

b. transmitting a multiplicity of closed-ended questions to said user concerning information specific to said user wherein each closed-ended question provides the possible responses or the possible responses are inherent in the question;

c. receiving responses to said closed-ended questions from said user; and

d. providing said user with said desired service only if the number of incorrect responses to said closed-ended questions does not exceed a certain limit.

2. The method of claim 1, wherein all of said multiplicity of closed-ended questions are transmitted to said user before either refusing said user said desired service if the number of incorrect responses exceeds said certain limit or providing said user with said desired service if the number of incorrect responses does not exceed a certain limit.

3. The method of claim 1, wherein the possible answers to said multiplicity of closed-ended questions remains substantially similar each time they are transmitted to a user.

4. The method of claim 3, further comprising:

imposing a lock condition such that said user cannot obtain said desired services using said method if the number of incorrect responses over a predetermined period exceeds a lock limit.

5. The method of claim 4, wherein all of said multiplicity of closed-ended questions are transmitted to said user before either refusing said user said desired service if the number of incorrect responses exceeds said certain limit or providing said user with said desired service if the number of incorrect responses does not exceed a certain limit.

6. A method of ascertaining the authenticity of a user using an automated computer system before providing said user with a desired service, said method comprising using an automated computer system to perform the following steps:

a. receiving a request for a desired service from said user;

b. fetching a question set corresponding to said user, said question for reducing guessing set having a multiplicity of closed-ended questions wherein the possible responses to each closed-ended question are either provided by the question or inherent in the question;

c. transmitting a closed-ended question from said question set to said user;

d. receiving a response from said user selected from said possible responses;

e. recording whether said response is correct or incorrect;

f. reiterating steps c through e at least once and until a predetermined number of closed-ended questions of said question set have been transmitted to said user, and

g. providing said user with said desired service if the number of incorrect responses does not exceed a certain limit.

7. The method of claim 6, wherein said question set relates to private information.

8. The method of claim 7, wherein said response is selected from the group consisting of true/false, yes/no, and multiple choice indica.

9. The method of claim 6, wherein the possible responses corresponding to a particular closed-ended question remain substantially the same each time said closed-ended question is transmitted to a user.

10. The method of claim 6, wherein said predetermined number of questions from said question set is all the questions from said question set.

11. The method of claim 6, wherein said certain limit is 0.

12. The method of claim 6, further comprising:

imposing a lock condition such that said user cannot obtain said desired services using said method if the number of incorrect responses over a predetermined period exceeds a lock limit.

13. The method of claim 6, further comprising:

receiving a call from a user;

transmitting an initial question to said user, said initial question requesting a selection of a particular user specific category; and

receiving a selection for a particular user specific category.

14. An apparatus for ascertaining the authenticity of a user before providing said user with a desired service, said apparatus comprising:

a processor;

a telephone network interconnection operatively connected to said processor, said telephone network interconnection having means for transmitting and receiving messages between said user and said apparatus;

a database operatively connected to said processor, said database having information pertaining to a particular user specific category;

memory operatively connected to said processor, said memory having instructional means residing therein for enabling said processor to perform the following process;

a. receiving a request for a desired service from said user;

b. fetching a question set corresponding to said user, said question set having a multiplicity of closed-ended questions wherein the possible responses to each closed-ended question are either provided by the question or inherent in the question for reducing guessing;

c. transmitting a closed-ended question from said question set to said user;

d. receiving a response from said user selected from said possible responses;

e. recording whether said response is correct or incorrect;

f. reiterating steps c through e at least once and until a predetermined number of closed-ended questions of said question set have been transmitted to said user, and

g. providing said user with said desired service if the number of incorrect responses does not exceed a certain limit.

15. The apparatus of claim 14, wherein the possible responses corresponding to a particular closed-ended question remain substantially the same each time said particular closed-ended question is transmitted to said user.

16. The apparatus of claim 14, wherein said instructional means further enable said processor to perform the following step:

imposing a lock condition such that said user cannot obtain said desired services using said apparatus if the number of incorrect responses over a predetermined period exceeds a lock limit.
