Digital watermarking is a process in which a piece of information is embedded into a digital data. In this article we review the digital watermarking scheme of image which uses DFT to embed the watermark. Digital watermarking using DFT has attracted researchers due to the fact that watermark using DFT are RST invariant compared to other scheme using other transforms such as DCT or DWT. In the presented article, we tried to cover all the aspect of digital watermarking particularly on DFT based scheme. We also gave some terminology used in the digital image watermarking and briefly discuss the attacks involved in digital image watermarking.

“…The most popular techniques in this category are Discrete Cosine Transform (DCT), Discrete Wavelet Transform (DWT) and Discrete Fourier Transform (DFT). The advantage of these techniques is they can overcome possible compression and more robust against geometric transformation such as rotation, scaling, translation and cropping; but, the disadvantage is they need a certain amount of computation which take longer time to produce [10].…”

Abstract-Digital watermarking is seen as a necessary and important field to be developed since the attacks and manipulations of digital documents and media are actively done. This paper surveys and reviews some basic theory about digital watermarking, such as the technique classification, requirements and possible attacks nowadays. Since all data in medical images are significantly important, the demand for the authentication is high. Therefore, this paper also focuses on a specific application of digital image watermarking for medical images which are tamper localization.

“…The watermarked image I' is then transmitted along a communication channel. The watermark can be detected or extracted later by the receiver now if both the watermarking image and original image identical then the process is considered to be successful; otherwise, the process is considered failed [8].…”

“…Many digital image and video compression schemes use a block-based DCT, because this algorithm minimizes the amount of data needed to recreate a digitized image. In particular, JPEG and MPEG use the DCT to concentrate image information by removing spatial data redundancies in two-dimensional images [19], the general steps for any block based DCT algorithm can be shown below [6]:…”

E-governmental applications have to find a solution for efficient and effective mechanism for authenticating and signing official documents. We propose and implement a mechanism for issuing secure electronic authentic governmental documents using watermark technology.The proposed mechanism constructs a watermark from domain name and MAC address of the governmental institution of interest. The watermark is augmented into the governmental document that is available in the form of image. This new mechanism promises allows the usage of watermarking to guarantee the authenticity and integrity of official documents. It can discover the change in these documents and the place where this change occurred. Proven by our experimental results, the proposed mechanism is secure and robust as the watermark will be embedded in multiple places inside the document where sensitive data is located, this way we can significantly reduce the probability of successful fraud of electronic documents.
