摘要： 基于安全的信息隐藏范式的思想，提出利用插值的方法，将秘密信息组织为图像的插值点插入到图像中，实现了安全隐写，并且在隐写过程中引入随机性，使隐写系统变得更加安全。现有多数方法是利用原图中已存在的冗余进行信息隐藏，该文提出的利用插值的方法相当于增加冗余，为信息隐藏提供了新的思路。

Abstract: Based on the thought of secure paradigm, a secure steganographic system using interpolation is achieved. It inserts interpolation points that denote secret into images. Besides, randomicity is imported during the steganographic process to make the system more secure. At present, the majority of information hiding methods utilize redundancy that has been existent in the original image; however, the method using interpolation is different. It carries out information hiding utilizing additive redundancy.

Key words: steganography, secure paradigm, interpolation, security, randomicity
