Data is transferred in public communication system is not secure because of interception and improper manipulation by third party. So the best solution for this issue is Steganography, which is technique of writing hidden messages in such a way that no one apart from the sender and main receiver recipient detect the existence of message, a form of security through obscurity. In this thesis, the Steganography method used is based on Steganography which is concerned with embedding secret data in a file. In this thesis a semi-reversible data hiding method that utilizes interpolation and the least significant substitution technique is proposed with watermarking technique. The least significant-bit (LSB) based technique are very popular for Steganography in spatial domain. The easiest LSB technique simply replaces the LSB in the cover image with the bits from secret information. Further latest techniques use some criteria to identify the pixels in which LSB(s) can be replaced with the bits of secret information. The performance of hiding method was tested using the fi- delity measures Mean Square Error (MSE), and Peak Sig- nal to Noise Ratio (PSNR) to describe the overall error rate. The simplest LSB technique simply replaces the LSB in the cover image with the bits from secret information. Further latest techniques use some criteria to identify the pixels in which LSB(s) can be replaced with the bits of secret information
