"Abstract? Now days, internet resulted in an considerable growth in multimedia applications. The explosive advancement of internet has made it easier to send the data/image accurate and faster to the destination. Besides this, it is easier to modify and misuse the valuable information through hacking at the same time. Digital watermarking is one of the proposed solutions for copyright protection of multimedia data. A watermark is a technique, image or text is impressed onto the another Image, which provides evidence of its authenticity. Here an invisible watermarking technique (least significant bit) and a visible watermarking technique is implemented. This paper presents the general overview of image and text watermarking and different security issues such as ambiguity attack, cryptographic attacks etc . Various attacks such as ambiguity attack, cryptographic attacks etc. are also performed on watermarked images and their impact on quality of images is supplementary of paper. In paper, Image Watermarking using Least Significant Bit (LSB) algorithm has been used for embedding the message/ into the image. This work has been implemented through MATLAB. "
