Abstract

최근의 지능형 영상감시 기술은 인공지능 기반 영상분석을 통하여 기존에 제공하지 못했던 선제적 예측감시 등 다양한 서비스의 제공이 가능하게 되었다. 지능형 영상감시에 있어 보안성의 확보는 필수적이며, 원본 CCTV 영상 데이터에 대한 조작이 발생할 경우, 사회적으로 큰 문제로 이어질 수 있다. 따라서 본 논문에서는 블록체인 기반의 지능형 영상감시환경을 제안하였다. 제안한 방식은 CCTV 영상데이터의 위변조 방지를 보장하며, 엣지 블록체인을 통하여 ROI 프라이버시 보호가 가능하여 객체의 프라이버시 노출이 없다는 장점이 있다. 또한, 영상 중복제거가 가능하여 전송 효율을 높이고 스토리지를 절감할 수 있어 효율적이다.

Recently, the intelligent video surveillance technology has become able to provide various services such as predictive surveillance that have not been provided previously. Securing the security of the intelligent video surveillance is essential, and malicious manipulation of the original CCTV video data can lead to serious social problems. Therefore, in this paper, we proposed an intelligent video surveillance environment based on blockchain. The proposed scheme guarantees the integrity of the CCTV image data and protects the ROI privacy through the edge blockchain, so there is no privacy exposure of the object. In addition, it is effective because it is possible to increase the transmission efficiency and reduce storage by enabling video deduplication.
