Abstract

This study is a system development for voice information protection equipment in major meetings and places requiring security. Security performance and stability were secured with information leakage prevention technology through generation of false noise and ultrasonic waves. The cutoff frequency band for blocking the leakage of voice information, which has strong straightness due to the nature of the radio wave to the recording prevention module, blocks the wideband frequency of 20~20,000Hz, and the deception jamming technology is applied to block the leakage of voice information, greatly improving the security. To solve this problem, we developed a system that blocks the recording of a portable smartphone using a battery, and made the installation of a separate device smaller and lighter so that customers do not recognize it. In addition, it is necessary to continuously study measures and countermeasures for efficiently using the output of the anti-recording speaker for long-distance recording prevention.

본 연구는 주요 회의 및 보안을 요하는 장소의 음성 정보보호 장비에 대한 시스템 개발이다. 가청소음 및 초음파 발생을 통한 정보 유출 방지기술로 보안 성능 및 안정성을 확보하였다. 녹음방지 모듈에 대한 무선전파의 특성상 직진성이 강한 음성정보 유출 차단을 위한 차단주파수 대역은 20~20,000Hz 광대역 주파수 차단 음성정보 유출차단을 위해 기만재밍 기술을 적용함으로 보안성을 크게 향상시켰다. 이러한 문제 해결을 위해 배터리를 이용한 휴대용 스마트폰 녹음을 차단시켜주는 시스템을 개발하였고, 별도의 장치 설치를 고객이 인지하지 못하도록 소형·경량화시켰다. 아울러, 원거리 녹음방지를 위하여 녹음방지 스피커의 출력을 효율적으로 사용하기 위한 방안 및 대책은 지속적으로 연구가 필요하다.
