摘要：Along with the different data hiding schemes, lossless data hiding has attained the improved performance currently identified as reversible watermarking guarantees extraction of the hidden information totally revival the original image. The existing work presented a high capacity reversible watermarking (RW-HPBS) method based on histogram processing and blocks selection. RW-HPBS approach exploits concept of down sampling for effectively increasing capacity and integrity control and authentication related applications. The authentication process is achieved by taking a secondary gain of position map previous to creature compressed and embedded as support information. This process does not concern about the interpolation error expansions. The proposed work presents high image quality and resilience controlled Reversible Watermarking with Interpolation Error Expansion Technique. The image interpolation is the process of estimating the missing pixels. The pixels present in low resolution image are called sample pixels. Using sample pixels of high resolution image are interpolated to construct interpolated image. The difference between interpolated pixel value and original pixel value is called interpolation error. Performance measures in terms of computational complexity, resilience rate, blind data extraction, and extracted image quality.
