摘要 在分析现有DCT系数加密算法安全性的基础上,提出了一个空域加密和频域加密相结合的JPEG压缩图像加密算法。理论分析与计算机仿真实验表明,该算法具有很好的加密效果,对压缩算法的压缩效率影响很小,能充分满足压缩图像加密算法的要求。 We proposed an encryption scheme for the compressed image.In the scheme,the image data is first encrypted in space domain and then is encrypted in frequency domain.The proposed scheme can not only achieve high security but also guarantee the efficiency of the compression algorithm.
