Abstract
Digital watermarking is a method to provide authenticity and copyright ownership to digital content by embedding any presume content like audio, text, data or video into the original content. This embedding of data should not damage the quality of the original content and should fulfill its objective also. From a decade a number of researchers are working on watermarking for providing security, robustness and imperceptibility to the digital images. This paper describes the information about watermarking in terms of its characteristics, application areas, types and various attacks performed on it. A comparative study of various techniques used in the field of watermarking is provided here by measuring their performance in terms of various characteristics. A number of performance measures used by various researchers are also discussed here along with possible attacks. This paper can help researchers to find various techniques used in watermarking field and their performances against various attacks for further proceedings. Keywords Digital watermarking . Robustness . Imperceptibility . DCT . DWT . SVD . CNN . NN
1 Introduction Today all information is available in digital form on the internet. This availability of data on internet allows users to share and access all the data and information in digital form which infringes the law of copyright ownership. The information contained in watermarked content can be used for communication between sender and receiver and no one else will know its * Preeti Garg [email protected] R.

existence in carrier content. [93]. Digital watermarking allows the user to add a design like a logo or image in some cover image to prove authenticity, copy control, fingerprinting and ownership. Digital watermarking has various applications like copyright protection, digital right management, fingerprinting, image and content authentication, tamper proofing and many more [81]. A watermarking algorithm should maintain the quality of the original image as well as it should embed watermark in such a way that watermarked image shows robustness against various attacks like Gaussian noise, JPEG compression or rotational attacks [128]. Watermarking can be done on any text, image, audio or video. In this paper authors have focused on watermarking work done on digital images. Watermarking on images can be done in spatial and transform domain. In spatial pixel values are used for embedding while in transform domain, first the pixel values are converted into frequency coefficients and then these are use
