Abstract

Disclosed is a secure telephone call management system for authenticating users of a telephone system in an institutional facility. Authentication of the users is accomplished by using a personal identification number, preferably in conjunction with speaker independent voice recognition and speaker dependent voice identification. When a user first enters the system, the user speaks his or her name which is used as a sample voice print. During each subsequent use of the system, the user is required to speak his or her name. Voice identification software is used to verify that the provided speech matches the sample voice print. The secure system includes accounting software to limit access based on funds in a user'"'"'s account or other related limitations. Management software implements widespread or local changes to the system and can modify or set any number of user account parameters.

Claims

1. A method for determining a number of participants of a telephone conversation, the method comprising:

sampling voice data from a telephone conversation;

analyzing the sampled voice data;

identifying the number of participants of the telephone conversation based on the analyzing; and

taking a predefined action when the number of participants is greater than a predetermined number.

2. The method of claim 1, wherein the analyzing includes biometric voice identification.

3. The method of claim 1, wherein the predefined action is one or more of terminating the telephone call on which the telephone conversation is taking place and alerting the appropriate authorities.

4. The method of claim 1, wherein the predetermined number is two.

5. The method of claim 1, further comprising:

searching a database of voice data entries of users authorized to participate in the telephone conversation for a voice data entry that sufficiently matches the sampled voice data;

determining that the database does not contain a voice data entry that sufficiently matches the sampled voice data based on the search;

concluding that an unauthorized user is participating in the telephone conversation based on the determining; and

taking a second predefined action in response to the concluding.

6. The method of claim 5, wherein the second predefined action is one or more of terminating the telephone call on which the telephone conversation is taking place and alerting the appropriate authorities.

7. The method of claim 5, wherein the database includes one or more of voice samples of authorized users and voiceprints of authorized users.

8. A system for determining a number of participants of a telephone conversation, the system comprising:

at least one processor and/or circuit configured to;

sample voice data from a telephone conversation;

analyze the sampled voice data;

identify the number of participants of the telephone conversation based on the analyzing; and

take a predefined action when the number of participants is greater than a predetermined number.

9. The system of claim 8, wherein the analyzing uses biometric voice identification.

10. The system of claim 8, wherein the predefined action is one or more of terminating the telephone call on which the telephone conversation is taking place and alerting the appropriate authorities.

11. The system of claim 8, wherein the predetermined number is two.

12. The system of claim 8, further comprising:

a database of voice data entries of users authorized to participate in the telephone conversation;

wherein the at least one processor and/or circuit is further configured to;

search the database for a voice data entry that sufficiently matches the sampled voice data;

determine that the database does not contain a voice data entry that sufficiently matches the sampled voice data based on the search;

conclude that an unauthorized user is participating in the telephone conversation based on the determining; and

take a second predefined action in response to the concluding.

13. The system of claim 8, wherein the second predefined action is one or more of terminating the telephone call on which the telephone conversation is taking place and alerting the appropriate authorities.

14. The system of claim 8, wherein the voice data entries include one or more of voice samples and voiceprints.

15. A system, comprising:

at least one processor and/or circuit configured to;

monitor audio information of a telephone conversation between a local user and a remote user,

obtain a first voiceprint of the local user from the audio information;

obtain a second voiceprint of the remote user from the audio information;

obtain a third voiceprint from the audio information;

compare the third voiceprint with the first voiceprint and the second voiceprint;

identify the third voiceprint as belonging to a third party based on the comparing; and

take a predefined action in response to the identifying of the third voiceprint as belonging to the third party.

16. The system of claim 15, wherein the predefined action is one or more of terminating the telephone call on which the telephone conversation is taking place and alerting the appropriate authorities.

17. The system of claim 15, wherein the obtaining the first, second, and third voiceprints uses biometric voice analysis.

18. The system of claim 15, further comprising:

a voiceprint database;

wherein the control platform is further configured to;

store voiceprints of authorized users in the voiceprint database;

search the voiceprint database for a stored voiceprint sufficiently matching the third voiceprint;

determine that the voiceprint database does not contain a stored voiceprint substantially matching the third voiceprint based on the search;

conclude that an unauthorized user is participating in the telephone conversation based on the determining; and

take a second predefined action in response to the concluding.

19. The system of claim 18, wherein the second predefined action is one or more of terminating the telephone call on which the telephone conversation is taking place and alerting the appropriate authorities.

20. The system of claim 15, further comprising:

a second voiceprint database;

wherein the control platform is further configured to;

store voiceprints of unauthorized users in the second voiceprint database;

search the second voiceprint database for a stored voiceprint sufficiently matching the third voiceprint;

determine that the second voiceprint database contains a stored voiceprint substantially matching the third voiceprint based on the search;

conclude that an unauthorized user is participating in the telephone conversation based on the determining; and

take a third predefined action in response to the concluding; and

wherein the third predefined action is one or more of terminating the telephone call on which the telephone conversation is taking place and alerting the appropriate authorities.
