Reversible Data Hiding in Encrypted Image using Chaotic Algorithm
Akshay Varkale, Nilesh Sharma · 2014
nowadays, the reversible data hiding research has become major issue. The reversible data hiding techniques are researched to improve the distortion in sensitive images. The embedding process of this technique is the some of the general data hiding scheme. However, the extraction process has an additional method in comparison with general data hiding scheme. After the embedded secret data is extracted, the cover image can be completely restored to its original state The proposed method can achieve real reversibility, that is, data extraction and image recovery are free of any error. Result show that our method can embedded the data and image in best quality and it can be calculate with the help of PSNR. In our proposed work we also find final PSNR (dB) which shows the value is equal to infinite that means our image is of good quality and distortion is less.
