Improving the Modified Matriz Encoding on Steganography Method(Steganographic Methods considering The Quantization Effect on Coefficient Modification)

摘要：

In this paper, we present a steganographic method that improves some existing data hiding methods.This method works in compressed domatin(JPEG)of image,In most of the previous methods, the usually Change Coefficients to hide information. And some methods tried to enhance the performance of general steganograhpic method like F5 including Matrix Ecoding.In avove papers, they achieve to reduce the distortion after hiding data into coefficient of compressed domain.We have been analyzed the effect of quantization table during data hiding on compressed domain.Finally,we considered that there would be more chance to reducte the distortion of steganograhpic method.As the result, this paper proviedes little bit more improved result in view of image quality.This result can give some contribution for future steganographic methods which will work in compressed domain like JPEG.
