Abstract: Methods and systems for anonymizing an identity of a caller using a voice print match. One system includes a surveillance system including a camera and a microphone; and a dispatch computer. The dispatch computer is configured to receive a voice call from the caller, generate a voice print from the voice call, compare the voice print to a plurality of stored voice prints, and, in response to the voice print not matching any of the plurality of stored voice prints, transmit the voice print to the surveillance system. The surveillance system is configured to receive the voice print, capture audio data via the microphone, compare the audio data to the voice print, and, in response to identifying a match between the voice print and the audio data, tag image data, captured via the camera, corresponding to the audio data for redaction.

Abstract: A system and method for redaction based on group association is disclosed. The method includes carrying out an analysis that includes coming to a determination that, notwithstanding at least some features of a plurality of group-associated objects are being concealed, a visible association between the objects in combination with size and shape definitions for corresponding redactions of the group-associated objects is such that an identity deducibility condition is either met or is not met.

Abstract: A method and apparatus for transmission in a trunked radio communication system comprises a first mobile radio subscriber unit receiving identity data from one or more other mobile radio subscriber units. The first mobile radio subscriber unit detects the distance from the first mobile radio subscriber unit to each of the one or more other mobile radio subscriber units. This information is transmitted to the infrastructure of the system, which selects a communication channel for the first mobile radio subscriber unit, so as to reduce close proximity interference between the mobile radio subscriber units. The mobile radio subscriber units may check for blocking conditions prior to initiating communication, and when necessary may delay transmission. The check may be based on information received via Bluetooth from other mobile radio subscriber units, and Bluetooth signal strength information.
