Digital Multimedia contents like text, image, audio and video are widely used and are very easy to transmit over the Internet, and hence the copyright protection has been receiving and increasing attention these days. Other than copyright protection Digital Watermarking is now used for Digital Marketing and promotional Services. A Static Promotional media is now can be made highly productive Dy...

Safeguarding creative content and intellectual property in a digital form has become increasingly difficult as technologies, such as the internet, broadband availability and mobile access advance. It has grown to be progressively easier to copy, modify and redistribute digital media, resulting in great declines in business profits. Digital watermarking is a technique which has been proposed as ...

The contemporary period of information technology facilitates simple duplication, manipulation and distribution of digital data. This enduringly, has insisted the rightful ownership of digital images to be protected efficiently. For content owners and distributors, there emerged a necessary concern in regard to the content authentication of digital images as well as copyright protection. A late...

Fingerprinting protocol applies a watermarking technique to embed a fingerprinting information in a digital content such as music, image, movie, etc.. The cryptographic protocol is studied by many researchers, but how to apply watermarking techniques is not remarked. In this paper, we study the problem to implement the watermarking techniques in the fingerprinting protocol, and then propose an ...

Watermark is a pattern or image coverted in a paper to discourage counterfeiting of the document. Encoding such a pattern or signal into digital data like image, music, video etc is called Digital Watermark also known as Forensic watermarking. The embedding of the watermark information takes place by manipulating the content of the digital data. The hiding process should be such that the modifi...

Digital watermarking is extensively used in ownership authentication and copyright protection. In this paper, we propose an efficient thresholding scheme to improve the watermark embedding procedure in an image. For the proposed algorithm, watermark casting is performed separately in each block of an image, and embedding in each block continues until a certain structural similarity threshold is...

Digital watermarking is the act of hiding a message related to a digital signal (i.e. an image, song, video) within the signal itself. It is a concept closely related to steganography, in that they both hide a message inside a digital signal. However, what separates them is their goal. Watermarking tries to hide a message related to the actual content of the digital signal, while in steganograp...

Image watermarking technique embeds copyright information (watermark) into host image so as to perform its protection and authentication. Schemes of embedding digital watermark into grayscale images have been researched and developed greatly. However color image is more common in our everyday life and it contains more information than grayscale image and provides information to against the atta...

Watermarking is the process that embeds data called a watermark, tag or label into a multimedia object, such as images, video or text for their copyright protection. According to human perception, the digital watermarks can either be visible or invisible. A visible watermark is a secondary translucent image overlaid into the primary image and appears visible to a viewer on a careful inspection....

Unified Modeling language (UML) is one of the important modeling languages used for the visual representation of the research problem. In the present paper, UML model has been designed for the watermarking in the image file using transform method because Digital watermarking is the process of embedding some information into a digital signal which is used to verify the authentication of image fi...
