| 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. |
