A novel approach of Image steganography-hiding the confidential data into an image

Abstract: The paper proposed a new steganographyembedding and extraction system that uses Direct Sequence Spread Spectrum technique. DSSS is used to enhance the robustness and security of the system. Enhancement has been accomplished in strength on the cost of decreasing the capability of hiding. The noiselessness of the image steganography embedding and extracted is assessed by using peak signal-to-noise ratio (PSNR).
This steganography plan manages the extraction of the hide data without unique picture; consequently the visually impaired plan was acquired. Peak Signal to Noise Ratio (PSNR) and Similarity Ratio (SR) are figured to measure picture quality. Likewise, the competency of the proposed technique is checked under normal picture preparing operations and a relative study is made against the previous technique .MATLAB R2012a has been used as an implementation platform.
