| 摘 要： | 为了提高信息隐藏技术的安全性和鲁棒性,采用图像变换域技术对覆盖图像进行正交变换,把秘密信息嵌入到变换域系数中,使特定的秘密信息伪装隐藏在公开的非机密数字载体中进行传递,使观察者和监测系统无法察觉到特定信息的存在.

| Abstract: | Information hiding is a new direction in information security, whose aim is to hide the existence of the secret information.The aim, principle and methods of image transformation, and the basic concept, principle, model, main characteristics and general methods of information hiding are introduced. Then the methods of information hiding based on the transformation domain of image,as well as the hiding processes and detecting methods of the secret information are discussed. |
