Digital watermarking has been proposed as a solution to the problem of copyright protection of multimedia documents in networked environments. It makes possible to tightly associate a code (called a watermark) to an image allowing the identification of the data creator. owner and so on. In this paper, we give a brief review of current research on digital image watermarking. multimedia data (e.g., digital audio, still images) and digital video.In order to be effective, an imperceptible watermark should meet the following requirements [ 1,2,3]:unobtrusive: it should be statistically and perceptually invisible to avoid data quality degradation and to prevent an attacker from finding and deleting it; readily extractable: the data owner or an independent control authority should easily extract it;

The recent developments of enormous computer networks have invoked insecurities related to copyright theft of digital media. To be precise, the virtual sharing of medical images over networks with a novel desire of improved medical diagnosis has led to the tampering of sensitive patient identity information. In this chapter, the authors have exemplified the need of watermarking with fragile medical image watermarking using saliency and phase congruency. Initially, the saliency and phase congruency methodologies are applied on the original medical image to highlight the object features. Based on the feature map, a mask is generated which segregates the area of interest from the portions containing visual medical information. An encrypted text, containing identity of the patient, is embedded into the area of interest of the image. The results of imperceptibility and fragility criteria are satisfactory towards the implementation of a fragile watermark as the extracted watermark is found to be corrupted upon unfaithful image processing modifications.
