摘要
信息隐藏技术已经成为信息安全领域研究的热点,JPEG压缩方案是数字图像损失信号的主要原因。为了提高密钥管理时的安全性和减少JPEG压缩的图像信号损失,给出了一种基于离散余弦变换域的信息隐藏算法,该算法能够实现信息的盲提取,并且利用该算法把密钥以ASCII码的形式隐藏到数字图像之中。实验结果表明,该算法不仅有良好的不可见性,而且对JPEG压缩等攻击具有理想的鲁棒性。
Information hiding technology has been a research hotspot in the area of information security, quantization is the main source of information loss in JPEG compression scheme. To increase the security of key management and reduce information loss by JPEG compression, a information hiding algorithm based on DCT is proposed, and information can be extracted blind. The experimental results show that hided information by the algorithm is invisible and robust enough to JPEG compressing attack, and so on.
