“…These gray level values will be different from that of the source document because transformation Ì ½ has been occurred during halftoning process and transformation Ì ¾ has been occurred during scanning process. Now, we can compute the composite transformation Ì , resulting for a particular combination of printer and scanner, and it can be estimated by using the popular polynomial interpolation technique which is as shown as equation (6). (6) are Coefficients.…”

“…Typically,the techniques are specific to the type of document and its content. Examples of this class of techniques include methods that embed information in hardcopy text documents through embedding information in printed halftone images [1] [2][3] [4] and methods for embedding information in images that are designed to be robust to the printing process [5] [6]. Usually these techniques require to capture the printed document in electronic form,from which the embedded data may be recovered or visible pattern may be revealed through suitable processing.…”

Abstract-This paper describes a method of hiding a copyright symbol into an print image which can survive against print-scan process. Copyright protection is a challenging problem specially for printed image document. Digital watermarking is one of the most efficient method to protect an image from unauthorized use. In this paper we propose an inexpensive hardcopy watermarking technique which can survive print-scan transformation as well as small degree of geometric distortion. Experimental result shows the effectiveness of the proposed watermarking scheme. The proposed scheme could be used as an inexpensive method of copyright protection for printed document like passport, id card etc.

“…There is an inherent tradeoff between many of these attributes that plays a critical role in a real-world application. At the detector, robustness, false positive rate and speed often compete with each other [6]. During detector design these attributes must be balanced, to meet the application requirements.…”

The field of digital watermarking has recently seen numerous articles covering novel techniques, theoretical studies, attacks, and analysis. In this paper, we focus on an emerging application to highlight practical challenges for digital watermarking applications. Challenges include design considerations, requirements analysis, choice of watermarking techniques, speed, robustness, and the tradeoffs involved. We describe common attributes of watermarking systems and discuss the challenges in developing real world applications. Our application uses digital watermarking to connect ordinary toys to the digital world. The application captures important aspects of watermarking systems and illustrates some of the design issues faced.

“…As a result, digital content can be easily copied and illegally distributed over the Internet. Hence, there is a strong need of developing the techniques which can help to identify intellectual property of digital documents, see [1]. Digital Watermarking has emerged as a solution for protecting the intellectual property of digital data [1][2][3][4].…”

Abstract. In the recent years, several digital watermarking applications have been developed for copyright protection of digital images.In this article we have tested how they perform in practical applications. We have identified the most common operations performed by professional photographers and web developers, and tested the robustness of watermarks embedded using the applications for copyright watermarking. Our aim was to prove that commercially available software does not meet the requirements of photography and web industry. We have also identified areas in which the software should be improved in order to meet current and future requirements of the industry.
