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 restricting access to a call management system, the method comprising:

registering a user of the call management system in an institution, the registering including;

receiving a first image from the user via a camera;

verifying the first image is indicative of a face using image recognition; and

associating the verified first image with the user; and

storing the verified first image in a database; and

authenticating a call access attempt by the user, the authenticating including;

receiving the call access request by the user of the call management system;

prompting the user for a second image;

determining whether a visual characteristic of the second image is a statistical match to a visual characteristic of the stored verified first image; and

allowing or rejecting the call to proceed based on the determination.

2. The method of claim 1, further comprising:

after the allowing the call to proceed, sampling image data of the user during the call;

comparing the sampled image data with the visual characteristic of the stored verified first image; and

detecting if an unauthorized person is a party to the call based on the comparing.

3. The method of claim 2, further comprising:

taking a control action in response to detecting that an unauthorized person is a party to the call.

4. The method of claim 1, wherein receiving a first image includes using an infrared camera, and the first image, the first verified image, and the second image are infrared images.

5. The method of claim 1, wherein registering a user further comprises:

assigning an identification to the user; and

associating the identification with the first image in the database; and

wherein the authenticating further comprises;

receiving the identification from the user; and

locating the first image in the database using the identification.

6. The method of claim 5, further comprising:

in response to determining that the visual characteristic of the second image is a statistical match to the visual characteristic of the stored verified first image;

querying the database with the identification;

determining whether the user is authorized to place the call based on the querying; and

allowing or rejecting the call based on the determining whether the user is authorized to place the call.

7. The method of claim 1, further comprising:

monitoring call access attempts by the user to the call management system by updating the database.

8. The method of claim 1, wherein receiving a first image from the user via a camera further comprises:

prompting the user to position his/her face within a field of view of the camera, and wherein the prompting is implemented using a graphical user interface.

9. The method of claim 1, wherein prompting the user for a second image further comprises:

prompting the user to position his/her face within a field of view of the camera, and wherein the prompting includes implementing with a graphical user interface.

10. The method of claim 1, wherein the visual characteristic of the first image, the visual characteristic of the verified first image, and the visual characteristic of the second image are measures of face architecture.

11. An apparatus for restricting access to a call management system, the apparatus comprising:

a database; and

one or more processors and/or circuits configured to;

register a user of the call management system in an institution by being configured to;

receive a first image from the user via a camera;

verify the first image is indicative of a face using image recognition; and

associate the verified first image with the user; and

store the verified first image in the database; and

authenticate a call access attempt by the user by being configured to;

receive the call access request by the user of the call management system,

prompt the user for a second image;

determine whether a visual characteristic of the second image is a statistical match to a visual characteristic of the stored verified first image; and

allow or rejecting the call to proceed based on the determination.

12. The apparatus of claim 11, wherein the one or more processors and/or circuits are further configured to:

after allowing the call to proceed, sample image data of the user during the call;

compare the sampled image data with the visual characteristic of the stored verified first image; and

detect if an unauthorized person is a party to the call based on the comparison;

13. The apparatus of claim 12, wherein the one or more processors and/or circuits are further configured to:

take a control action in response to detecting that an unauthorized person is a party to the call.

14. The apparatus of claim 11, further comprising an infrared camera to capture the first image, and wherein the first image, the first verified image, and the second image are infrared images.

15. The apparatus of claim 11, wherein the one or more processors and/or circuits are further configured to:

assign an identification to the user; and

associate the identification with the first image in the database; and

wherein the one or more processors and/or circuits are further configured to authenticate by being configured to;

receive the identification from the user; and

locate the first image in the database using the identification.

16. The apparatus of claim 15, wherein the one or more processors and/or circuits are further configured to:

in response to determining that the visual characteristic of the second image is a statistical match to the visual characteristic of the stored verified first image;

query the database with the identification;

determine whether the user is authorized to place the call based on the querying; and

allow or rejecting the call based on the determination of whether the user is authorized to place the call.

17. The apparatus of claim 11, wherein the one or more processors and/or circuits are further configured to:

monitor call access attempts by the user to the call management system by updating the database.

18. The apparatus of claim 11, wherein the one or more processors and/or circuits are further configured to receiving a first image from the user via a camera by being further configured to:

prompt the user to position his/her face within a field of view of the camera using a graphical user interface.

19. The apparatus of claim 11, wherein the one or more processors and/or circuits are further configured to receiving a second image from the user via a camera by being further configured to:

prompt the user to position his/her face within a field of view of the camera using a graphical user interface.

20. The apparatus of claim 11, wherein the visual characteristic of the first image, the visual characteristic of the verified first image, and the visual characteristic of the second image are measures of face architecture.
