DISCRIMINANT SYSTEM OF AUDIO RECORDING EQUIPMENT AND THE METHOD

摘要

An audio recording equipment discrimination method according to the present invention comprises a step of receiving information of at least one recording equipment and data recorded by the recording equipment, extracting a noise feature vector for the recorded data, learning the extracted noise feature vector by the recording equipment, and generating a discrimination model; and a step of extracting a noise feature vector for any data recorded by any recording equipment, comparing the noise feature vector of any recorded data to the generated discrimination model, and discriminating the recording equipment in which any recorded data is recorded. The audio recording equipment discrimination system and the method thereof provide the integrity and authentication of a sound source by generating the discrimination model which learns the noise feature of each of the audio recording equipment and discriminating the recording equipment in which the sound source data is recorded for any sound source data. [Reference numerals] (AA) Start;(BB) End;(S201) Input at least one recording equipment and recording data;(S202) Extract each recording data's noise feature;(S203) Create a discrimination model by learning the extracted each recording data's noise feature;(S204) Input random recording data;(S205) Extract the random recording data's noise feature;(S206) Discriminate the corresponding record equipment for the extracted noise feature by comparing the created discrimination model and the random recording data noise feature
