Image Steganography for Data Embedding & Extraction using LSB Technique

Security is the main concern in today’s world due to the rapid growth of information technology. In this research work, the steganographic is the method or process in which the useful information or data, concealing into another form such as image, text, audio and video. The main concern in this work is to provide the confidentiality, availability, integrity and authenticity of information. In a steganographic technique that embeds concealment of information with unremarkable cover media so the third party and hackers do not provoke it. For digital image steganographic many applications of decryption, compression, encryption and embedding methods are used. Noise and quality of the images are reduced or change due to compression. The LSB (Least Significant Bit) insertion technique is used to sustain noise in the images. The parameters which are evaluated such as PSNR (Peak Signal to Noise Ratio) and MSE (Mean Square Error) of the proposed embedding system with respect to tradition technique and robustness is discussed and also providing security to secrete messages.
