Abstract
(EN)
The present invention relates to an auditory information security system and, more specifically, to an auditory information security system for preventing illegal leakage of auditory information by transmitting security signals, which are unspecified noise signals within a preset frequency band among frequency bands that the human ear cannot hear, and then, preventing the auditory information, including voices and sounds occurring in a specific area where wiretapping or recording is expected, from being collected by a wiretap or recorder.
(FR)
La présente invention concerne un système de sécurité pour informations sonores, et plus particulièrement un système de sécurité pour informations sonores conçu pour empêcher la fuite illégale d'informations sonores grâce à une transmission de signaux de sécurité, qui sont des signaux de bruit non spécifiés dans une bande de fréquences prédéfinie parmi des bandes de fréquences que l'oreille humaine ne peut pas entendre, puis empêcher la collecte par une table d'écoute ou un enregistreur des informations sonores, y compris des voix et des sons se produisant dans une zone spécifique où une écoute en ligne ou un enregistrement sont attendus.
