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.
Claims20
A communication monitoring method, comprising:
- receiving a communication that includes audio data of a recorded conversation and metadata, the metadata describing non-content information about the communication and including at least one timestamp;
- retrieving a previously-stored second communication from a database based on the metadata;
- correlating content of the received communication to content of the second communication, the correlating including:
- first comparing spoken content included in the audio data of the received communication to spoken content of the previously-stored second communication;
- and
- second comparing non-spoken content included in the audio data of the received communication to non-spoken content of the previously-stored second communication, the non-spoken content including speaking pauses, extra dialed digits, and progress tones;
- first determining, based on the first and second comparing, that the received communication is an inmate-to-inmate communication;
- second determining that the received communication is currently in progress;
- and
- terminating the communication in response to the first determining and the second determining.
A communication monitoring system, comprising:
- a database that stores previously-recorded communications;
- a transceiver configured to receive a communication involving an inmate of a controlled-environment facility, the communication including audio data of a recorded conversation and metadata, the metadata describing non-content information about the communication and including at least one timestamp;
- a processor configured to:
- retrieve a previously-recorded communication from the database based on the metadata;
- correlate content of the received communication to content of the second communication, the correlating including:
- first comparing spoken content included in the audio data of the received communication to spoken content of the previously-stored second communication;
- and
- second comparing non-spoken content included in the audio data of the received communication to non-spoken content of the previously-stored second communication, the non-spoken content including speaking pauses, extra dialed digits, and progress tones;
- first determine, based on the first and second comparing, that the received communication is an inmate-to-inmate communication;
- second determine that the received communication is currently in progress;
- and
- terminate the communication in response to the first determine and the second determine.
A method of identifying an inmate-to-inmate communication, comprising:
- receiving an inmate communication that includes audio data and metadata, the metadata describing non-content information about the inmate communication and including at least one timestamp;
- selecting a previously-stored communication having metadata that overlaps the metadata of the received communication;
- correlating content of the received communication to content of the second communication, the correlating including:
- first comparing spoken content of the received communication to spoken content of the selected previously-stored communication;
- and
- second comparing non-spoken content of the received communication to non-spoken content of the selected previously-stored communication, the non-spoken content including speaking pauses, extra dialed digits, and progress tones;
- first determining, based on the correlating, whether the received communication is an inmate-to-inmate communication;
- second determining that the received communication is currently in progress;
- and
- terminating the communication in response to the first determining and the second determining.
