Patent

CA 2621952

An apparatus and method for the preparation of a censored recording of an audio source according to a procedure whereby no tangible, durable version of the original audio data is created in the course of preparing the censored record. Further, a method is provided for identifying target speech elements in a primary speech text by iteratively using portions of already identified target elements to locate further target elements that contain identical portions. The target speech elements, once identified, are removed from the primary speech text or rendered unintelligible to produce a censored record of the primary speech text. Copies of such censored primary speech text elements may be transmitted and stored with reduced security precautions.
