Abstract

Secure system and method of detecting and preventing inmate to inmate message relays. A system and method which monitors inmate communications for similar phrases that occur as part of two or more separate inmate messages. These similar phrases may be overlapping in real time as in a conference call or can occur at separate times in separate messages. The communications that appear similar are assigned a score and the score is compared to a threshold. If the score is above a certain threshold, the communication is flagged and remedial actions are taken. If the flagged communication contains illegal matter then the communication can be disconnected or restricted in the future.

First claim

What is claimed is:

1. A communication monitoring method, comprising:
receiving video communication data including a plurality of images of a video communication;
performing facial analysis on the video communication data;
determining, based on the facial analysis, whether the video communication includes a plurality of local participants;
in response to determining that the video communication includes the plurality of local participants:
first comparing results of the facial analysis to a database of local resident faces;
identifying, based on the first comparing, local residents participating in the video communication; and
first determining whether the identified local residents are permitted or prohibited from jointly communicating;

in response to determining that the video communication does not include the plurality of local participants:
receiving second video communication data associated with an external video communication participant;
performing second facial analysis on the second video communication data;
second comparing results of the second facial analysis to the database of local resident faces;
second determining, based on the second comparing results, that the external video communication participant is an inmate of a controlled environment facility; and

taking remedial action in response to the first determining or the second determining.

2. The communication monitoring method of claim 1 , wherein the facial analysis includes isolating each distinct face within the video communication data and performing facial recognition analysis on each distinct face.

3. The communication monitoring method of claim 1 , wherein the identified local residents are inmates of the controlled environment facility.

4. The communication monitoring method of claim 1 , wherein the remedial action includes terminating the video communication.

5. The communication monitoring method of claim 1 , further comprising:
terminating the video communication based on the determining.

6. A video communication monitoring method for monitoring a video communication involving an inmate of a controlled environment facility, comprising:
receiving first video communication data of the video communication having video and audio information;
detecting, using image analysis, facial data in the received video communication data;
identifying the inmate based on the facial data;
receiving second video communication data of the video communication associated with an external video communication participant;
detecting, using the image analysis, facial data in the received second video communication data;
identifying a second participant of the video communication based on the facial data of the second video communication data;
comparing the facial data of the second video communication data with stored facial data of a plurality of inmates of the controlled environment facility;
determining, based on the comparing, a match between the facial data of the external video communication participant and one of the plurality of inmates; and
taking remedial action in response to the determining.

7. The video communication monitoring method of claim 6 , further comprising:
accessing a database record associated with the inmate that includes a plurality of permitted contacts;
determining whether the second participant is included in the plurality of permitted contacts.

8. The video communication monitoring method of claim 6 , wherein the remedial action includes terminating the video communication.

9. The video communication monitoring method of claim 6 , further comprising terminating the video communication in response to the determining of the match.

10. A communication monitoring system, comprising:
a transceiver configured to receive video communication data including a plurality of images of a video communication; and
one or more processors configured to:
perform facial analysis on the video communication data;
determine, based on the facial analysis, whether the video communication includes a plurality of local participants; and
in response to the determining that the video communication includes a plurality of local participants:
first comparing results of the facial analysis to a database of local resident faces;
identifying, based on the first comparing, the local residents participating in the video communication; and
first determining whether the identified local residents are permitted or prohibited from jointly communicating;

in response to determining that the video communication does not include the plurality of local participants:
receiving second video communication data associated with an external video communication participant;
performing second facial analysis on the second video communication data;
second comparing results of the second facial analysis of the external video communication participant to the database of local resident faces; and
second determining, based on the second comparing, that the external video communication participant is an inmate of the controlled environment facility; and taking remedial action in response to the first determining or the second determining.

11. The communication monitoring system of claim 10 , wherein the facial analysis includes isolating each distinct face within the video communication data and performing facial recognition analysis on each distinct face.

12. The communication monitoring system of claim 10 , wherein the identified local residents are inmates of the controlled environment facility.

13. The communication monitoring system of claim 10 , wherein the remedial action includes terminating the video communication.

14. The communication monitoring system of claim 10 , wherein the one or more processors are further configured to:
terminate the video communication based on the determining.
