摘要

基于视频序列的时域特性

提出一种应用帧间共谋策略的视频隐写分析算法。分析了视频序列中所含局部运动对隐写分析检测精度的干扰

将秘密信息和局部运动建模为双模噪声

据此提出基于视频帧间分块相关度的特征提取策略。隐写分析算法依据提取的特征应用GRNN分类器进行视频帧的分类

以识别含秘密信息的可疑视频帧

在一定程度上降低了局部运动的影响。实验结果表明该算法可实际应用于视频隐写分析。

Abstract

An inter-frame collusion based video steganalysis scheme（ICS） was proposed by utilizing the temporal corre-lation among video frames to find out whether secret data was hidden in the frames or not.Motions existing in video se-quence decreased the detection accuracy of steganalysis algorithms

which were taken into account in ICS steganalysis scheme by modeling motions and messages in video frame as a bimodal noise.Suspicious video frames were recognized by decision module employing GRNN classifier with features extracted by the inter-frame correlation strategy.Experi-mental results show the satisfying performance of the proposed scheme.
