Exemplary embodiments of the present disclosure are directed towards a system for masking original data and managing communications. The system comprising a first communication management module configured to receive communication requests associated with a plurality of identities from communication devices, said first communication management module is configured to send said plurality of identities to a second communication management module and a database is configured to store said plurality of identities by said second communication management module, said second communication management module is configured to search said plurality of identities from said database and retrieve the data associated with said plurality of identities, said second communication management module is configured to mask said retrieved data by a virtual data and said first communication management module and said second communication management module are configured to display said virtual data.

There is a growing problem in correctional facilities in which contraband devices may be smuggled into a correctional facility. These devices are not subject to the typical monitoring and control provided by the inmate communication system provided by the correctional facility, and thus pose a significant security risk. The present disclosure provides details of a system and method that leverages the sanctioned mobile devices and the wireless infrastructure of the inmate communication system to scan for and triangulate the location of contraband devices. The mobile and wireless infrastructure devices scan for transmissions indicative of a contraband device and send alerts to each other and to a central monitoring system. The central monitoring system then leverages multiple alerts to determine a location of the contraband device using multiple triangulation techniques. The triangulation may also be performed by the mobile devices themselves.

The present disclosure provides details of a system and method for detecting and monitoring a contraband device including communication devices by utilizing a combination of mobile devices, fixed monitoring devices, and a contraband monitoring center. The mobile devices include smart phones or tablets that are borrowed, rented, or purchased by an inmate from a correctional facility. These mobile devices are configured to detect, monitor, and intervene in the communications of target devices. Further, the mobile devices are configured to communicate with fixed monitoring devices located throughout the correctional facility in performing intervention operations. The contraband monitoring center may also be utilized in the coordination, monitoring, and intervention of target devices.

A hands-free intercom may include a user-tracking sensor, a directional microphone, a directional sound emitter, a display device, and/or a communication interface. The user-tracking sensor may determine a location of a user so the directional microphone can measure vocal emissions by the user and the directional sound emitter can deliver audio to the user. The hands-free intercom may provide privacy to the user. The hands-free intercom may prevent an eavesdropper from hearing the user's vocal emissions, for example, by canceling the vocal emissions at the eavesdropper's ear. The directional sound emitter may deliver out-of-phase sound to cancel the vocal emissions. The hands-free intercom may also, or instead, cancel ambient noise at the user's ear. The hands-free intercom may measure or predict a filtration of the sound to be canceled and compensate for the filtration when canceling the sound.

An isolation unit may include input pins to receive an electrical signal induced by ambient sound waves incident on an appliance in a powered-off state, one or more first transformers, connected to the input pins, to electrically isolate the induced electrical, one or more second transformers, connected to the first transformers, to provide a common mode choke function on the induced electrical signal, one or more inductors, connected to the one or more second transformers, one or more resistors, connected to the one or more inductors, wherein the one or more inductors and the one or more resistors are configured to limit an amplitude of a current of the induced electrical signal, and output pins, connected to the one or more inductors, to receive a modified electrical signal from the one or more inductors to propagate the modified electrical signal to a downstream cable.

A method of identifying recording of a conversation during a communication session, including establishing a communication session between a first participant and one or more remote participants, transmitting audio packets from a communication device of the first participant to the one or more remote participants, receiving audio packets from the one or more remote participants, including echo packets responsive to the transmitted audio packets, analyzing the received audio packets by an analysis application to identify delays in the echo packets relative to the transmitted packets providing an indication of the presence of a recording application at a communication device of a remote participant, notifying the communication device of the first participant.

Systems and methods insert a modulated signal into audio of a controlled-environment facility resident's side of a call, such as by a controlled-environment communication apparatus, or the like. The same or a different controlled-environment communication apparatus, or the like, may detect the same and/or another modulated signal inserted into the audio of the same and/or another controlled-environment facility resident's side of the call in the audio of an other party's side of the call. The same or a different controlled-environment communication apparatus, or the like, may determine if more than one modulated signal is present in the other call party's side of the call and alert an authority that more than one controlled-environment facility resident is taking part in the call.
