    Abstract :

    The scopes of information interchange between the users of internet are increasing in exponential pattern. The challenges are equivalently increasing with regards to image authentication and tamper detection. In recent days, the use of image segmentation in watermarking has been found to increase the performance of image tamper search significantly to extract a manipulated region so that prove the authenticity of image. In the various studies, novel characteristic of the watermarking such as pixel based and segments based image watermarking has been studied to embed watermark and help to find tamper segment of cover image as well as tamper watermark. Spatial and frequency watermarking algorithms reviewed as pre-processing steps for find tamper region and authentication of images. Here we reviewed various watermarking schemes for tamper detection and image authentication and find a novel concept of superpixel segments watermarking.
