摘要： 为了增加帧间相关性，有效检测时域同步攻击，改进了差分能量水印(DEW)算法，并引入有限状态机(FSM)模型.经实验验证，该水印对噪声等常见帧内干扰具有强鲁棒性，同时对恶意帧间攻击的脆弱性使其具备有效的同步攻击检测能力，并在不可见性、算法安全性方面有良好表现.

Abstract: In order to produce interframe correlation and efficiently detect timedomain synchronous attack, a differential energy watermarking (DEW) algorithm was improved and a finite state machine (FSM) model was introduced. The experiments show that the watermark keeps robust to common intraframe disturbance such as noise while its fragility to malicious interframe attack provides it effective detectability against synchronous attack. In addition, it performs well in invisibility and algorithm security.
