中文摘要：
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.
英文摘要：
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.
