基于矩阵变换的数字图像置乱技术

Digital Image Scrambling Technology Based on Matrix Transformation

以图像信息安全问题为背景,在Arnold变换的基础上,提出了密钥控制下新的利用矩阵变换对数字图像进行置乱与恢复的技术.结果表明:在图像信息隐藏中,这种技术能达到较好的加密与解密效果,而且易于实现,具有应用价值.

With the security problem of image information as the background, based on Arnold transformation, presents a new technology for scrambling and restoring digital image by means of matrix transformation under the control of secret key. The results show that, applied to image information hiding, this technology can produce diseired effects of encryption and decryption, further more, it is easy to realize and has application value.
