摘　　要：在网络隐写信息的攻击检测中,为了保护数据的隐私,需要加入大量伪装隐私对数据本质特征进行隐藏,使得被攻击后的攻击特征也被覆盖,导致特征淡化。传统的攻击检测几乎都是对固定攻击特征进行检测,无法检测隐写信息的安全。提出利用多层次加权模型的网络隐写信息传递系统攻击检测方法。搜索网络隐写信息传递中的可能攻击事件,针对搜集的攻击事件进行建模,获取信息隐藏状态下,遭受攻击的衡量标准,建立网络隐写信息传递系统攻击数据集合,得到攻击检测模型,实现网络隐写信息传递系统的攻击检测。实验结果表明,利用改进算法进行网络隐写信息传递系统的攻击检测,能够提高检测的准确性。Steganographic information is different from traditional information. Almost all the traditional attack detection methods can only detect the fixed attack characteristics, but the steganographie information security cannot be detected. Based on a multi-level weighted model, an attack detection method for steganographic information transmission systems is presented. The possible attack events in steganographie information transmission are searched, and the gathered attack events are modeled. Then an attack detection model for steganographic information transmission systems is established, and the steganographie information transmission network attack detection system is realized. Experimental results show that the improved algorithm can improve the accuracy of detection.
