Abstract In order to produce interframe correlation and efficiently detect timedomain 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 intraframe disturbance such as noise while its fragility to malicious interframe attack provides it effective detectability against synchronous attack. In addition, it performs well in invisibility and algorithm security.
