Partial image encryption system design for secure transmission of images

영상데이터의 안전한 전송을 위한 부분 영상 암호화 시스템 설계

This paper proposes partial image encryption system for secure transmission of images. Partial image encryption is suitable for real-time processing purpose of multimedia data that needs compression and encryption. Compression part uses modified SPIHT algorithm and encryption part uses AES. Partial image encryption is significant reduction in encryption time in comparison with whole image encryption.
