Abstract

A secure telephone call management system is provided for authenticating users of a telephone system in an institutional facility. Authentication of the users of the telephone call management system is accomplished by using a personal identification number, biometric means, and/or radio frequency means. The secure telephone call management system includes accounting software capable of limiting access to the system based on funds in a user's account, and includes management software capable of implementing widespread or local changes to the system. The system monitors a conversation in the telephone call to detect a presence of a first characteristic in audio of the conversation, and terminates the telephone call if the first characteristic does not match a second characteristic of biometric information of a user or a called party.

First claim

What is claimed is:

1. A system, comprising:
a voice sample database;
a control platform configured to:
receive a first voice sample from a first user;
store the first voice sample in the voice sample database;
receive first identifying information related to the first user; and
store the first identifying information in the voice sample database in correspondence with the first voice sample; and

an authentication module configured to:
receive a second voice sample from a second user;
receive second identifying information related to the second user;
find in the voice sample database third identifying information that substantially matches the second identifying information received from the second user;
retrieve from the voice sample database a third voice sample associated with the third identifying information;
compare the second voice sample with the third voice sample; and
authenticate the second user based on the comparison.

2. The system of claim 1 , wherein the first voice sample is a standardized phrase spoken by the first user.

3. The system of claim 1 , wherein the first voice sample is a name of the first user as spoken by the first user.

4. The system of claim 1 , wherein the first voice sample is a portion of a telephone conversation.

5. The system of claim 4 , wherein the portion of the telephone conversation corresponds to a predetermined duration of an initial portion of the telephone conversation.

6. The system of claim 1 , wherein the control platform is further configured to:
receive second information related to the first user; and
store the second information in the database in correspondence with the first voice sample.

7. The system of claim 6 , wherein the second information includes at least one of an identification number, a name of the first user, a phone number, a phone number of a party to be called, or a language preference.

8. The system of claim 1 , wherein the first identifying information includes a personal identification number.

9. The system of claim 1 , wherein the first identifying information includes a name of the first user.

10. A method, comprising:
receiving a first voice sample from a first user;
storing the first voice sample in a voice sample database;
receiving first identifying information related to the first user;
storing the first identifying information in the voice sample database in correspondence with the first voice sample;
receiving a second voice sample from a second user;
receiving second identifying information related to the second user;
finding in the voice sample database third identifying information that substantially matches the second identifying information received from the second user;
retrieving from the voice sample database a third voice sample associated with the third identifying information;
comparing the second voice sample with the third voice sample; and
authenticating the second user based on the comparison.

11. The method of claim 10 , wherein the first voice sample is a standardized phrase spoken by the first user.

12. The method of claim 10 , wherein the first voice sample is a name of the first user as spoken by the first user.

13. The method of claim 10 , wherein the first voice sample is a portion of a telephone conversation.

14. The method of claim 13 , wherein the portion of the telephone conversation corresponds to a predetermined duration of an initial portion of the telephone conversation.

15. The method of claim 10 , further comprising:
receiving second information related to the first user; and
storing the second information in the database in correspondence with the first voice sample.

16. The method of claim 15 , wherein the second information includes at least one of an identification number, a name of the first user, a phone number, a phone number of a party to be called, or a language preference.

17. The method of claim 10 , wherein the first identifying information includes a personal identification number.

18. The method of claim 10 , wherein the first identifying information includes a name of the first user.
