| 摘 要： | 随着数字媒体技术的飞速发展及广泛应用，数字媒体信息安全问题日益引起高度关注。由于数字媒体形式多样，以往的相关研究工作集中于某一具体媒体形式的安全保护，如文字、图像、声音、视频。在计算机及网络环境下，一切对象以数字化的形式出现。将所有数字媒体信息在复数基的形式下进行统一表达，给出数字媒体与复数之间的相互转换算法，从而将数字媒体之间的关系变换为复平面上点的几何关系，并实现了数字媒体的信息隐藏。

| Abstract: | With the rapid development and wide application of the digital media technology,the information security problem is becoming more and more highly attention.Because of the various kinds of medias,previous research works have focused on a specific digital media from,such as text,image,audio and video.As a fact that all the objects were expressed in digital forms under the environment of computer and network,a unified form for all kinds of digital media under the complex number base system was proposed.The algorithm of the digital media signal and the complex number intercom version were given,so the relationship among the digital media could be converted to the corresponding geometric relationship on the complex plane.In the experiments,the proposed method was applied to the application of the digital media information hiding. |
