摘要：In the field of communication, security is the most important issue now days. Most probably of data asecurity and data hiding algorithms have been developed. In the last decade, these algorithms worked as motivation for our research. In this paper, Image Steganography with watermarking using LSB and interpolation Techniques are used. We have designed a system that will allow a user to securely transfer text messages by hiding them in a digital image file using the local characteristics within an image. A combination of image Steganography and interpolation with watermarking provides a strong backbone for its security. In this paper, the proposed system not only hides large volume of data within an image. But it also limits the perceivable distortion that might occur in an image while processing it. This thesis has an advantage over other information security thesis because the hidden text is in the form of image, which is not obvious text information carriers. The performance of hiding method was tested using Mean Square Error (MSE), Peak Signal to Noise Ratio (PSNR) and embedding capacity of proposed system.
