为了实现图像的压缩和加密同步提出一种基于内嵌零树小波编码 (embedded zerotree wavelet, EZW) 的压缩和树形加密算法. 加密过程在比特平面编码与熵编码之间进行, 使用密钥对图像压缩产生的上下文和判决进行修正, 实现压缩和加密同步. 对算法进行仿真, 结果表明, 算法具有良好的压缩效率和安全性.

A novel joint compression-encryption algorithm based on embedded zerotree wavelet (EZW) coding is proposed. Encryption process is performed before entropy coding. The principles of the context modification and the decision modification and described. Simulation results show that the proposed algorithm has a good effect on security, and has the same compression efficiency compared to the original image compression algorithm.-
