基于抗转码视频处理技术的图像隐写算法

Image Steganography Based on Antitranscoding Video Processing Technology

使用传统的图像隐写算法编写后的信息的抗高维统计检测性能差,图像隐写计算消耗时间长。针对这一问题,基于抗转码视频处理技术设计了一种新的图像隐写算法,利用载体图像和预载体图像信息得到DCT系数,通过图像的分布规律设定分布参数为β和阈值T,确定失真函数,以±1的方式计算出修改概率,将隐秘信息拆分成两个二元,嵌入式编写到图像载体中,在公共信道里完成图像的隐写计算。为检测算法效果,与传统隐写算法进行实验对比,结果表明,基于抗转码视频处理技术设计的图像隐写算法具有很强的抗高维统计检测性能,隐写计算时间短,成本低,对于信息安全领域的学术研究和实际应用有着重要价值。

The information compiled by traditional image steganography algorithm has poor performance in resisting high dimensional statistical detection and takes a long time to compute image steganography. To solve this problem, a new image steganography algorithm based on antitranscoding video processing technology is designed. DCT coefficients are determined by using carrier image and precarrier image information. Distribution parameters and thresholds are set by image distribution law. Distortion function is determined. Modification probability is calculated by (+1). Stealth information is divided into two binaries and embedded into image carriers. In the public channel, the steganographic calculation of the image is completed. In order to detect the effect of the steganography algorithm, the experimental comparison with the traditional steganography algorithm shows that the image steganography algorithm based on antitranscoding video processing technology has strong anti-high-dimensional statistical detection performance, short steganography calculation time, low cost, and has important value for academic research and practical application in the field of information security.
