摘要
信息隐匿技术是信息安全研究的一个新领域,为了确保隐匿信息安全,研究了一种利用压缩编码作为载体的信息隐藏技术,给出了基于压缩编码思想的通用信息隐匿模型的具体实现方案。讨论了该模型的两种关键技术:数据变换和数据选择技术。运用文中所给的通用模型,通过实验得出图像嵌入量和图像质量的关系。
Information hiding is a new area in the research of information security. This paper presents a new information hiding technology using compress coding as carrier for the security information hiding and shows the specific project of information hiding model based on channel coding. It discusses on two key technologies of the model: switch of data and choice of data technology. Using the general model, the relation of quantity of image embedding and image quality is given by the experiment.
