“…Theo [1,[8][9][10]20], các lƣợc đồ thủy vân đƣợc chia thành thủy vân dễ vỡ và thủy vân bền vững. Thủy vân dễ vỡ [2][3][4][5][6][7][8][9][10][11][12] yêu cầu dấu thủy vân phải nhạy cảm (dễ vỡ) trƣớc những sự tấn công trái phép trên dữ liệu thủy vân, dù chỉ vài bít.…”

“…Mặt khác theo [1,20], các lƣợc đồ thủy vân có khả năng khôi phục lại dữ liệu gốc từ dữ liệu thủy vân thì đƣợc gọi là thủy vân thuận nghịch (reversible watermarking). Thủy vân thuận nghịch thƣờng sử dụng một số phép biến đổi nhƣ: mở rộng hiệu [2,7-8,10-11, 14-15,19]; dịch chuyển histogram [6]; wavelet nguyên [12], nén bảo toàn [18,22] và sử dụng đặc trƣng nén JPEG [3][4]9].…”

“…Ngoài ra, việc kết hợp kỹ thuật dự báo với mở rộng hiệu hoặc dịch chuyển histogram cũng nhận đƣợc nhiều sự quan tâm của các nhà nghiên cứu. Theo các tài liệu [1,20], trong nhiều ứng dụng của y tế, quân sự và nghệ thuật, việc khôi phục lại ảnh gốc từ ảnh thủy vân là một trong những yêu cầu bắt buộc. Bởi, chỉ cần một sự thay đổi nhỏ trên ảnh sử dụng so với ảnh gốc cũng có thể ảnh hƣởng đến kết quả chuẩn đoán của bác sỹ, hoặc gây ra các hệ lụy nghiêm trọng trong quân sự.…”

“…Imperceptibility and capacity are the two main properties in reversible watermarking. Imperceptibility measure the similarity between the original cover work and the watermarked cover data and capacity measures maximum number of information that can be embedded in to the cover work [4]. Barton (1994) [5] in his invention introduced method for authenticating information provided by the user in which he embeds an authentication data to digital data using a digital signature which is a compressed version of the digital block.…”

This paper proposes a visible watermarking scheme using Discrete Fourier Transformation and which is reversible with some additional information. In the proposed scheme follows one to one mapping between the DFT coefficient of the cover image and watermark. For the purpose of our scheme the watermark of different size is embedded into the standard test images. Experimental results shows that the watermarked image has good perceptible features and authorised user can recover the original cover image with superior visual quality. The peak signal ratio of the legally recovered image is >50db.

Digital Image watermarking is one of the most active and challenging subjects in the information hiding research because it is an efficient solution to protect the copyright of the digital media. This paper proposes a new robust watermarking approach based on the selection of singular features of host image into which the watermark has to embed. The host image initially subjected to a normalization process to find the invariant features and then the obtained invariant features are subjected to Integer Wavelet Transform ( I. INTRODUCTION Digital Image Watermarking [1,2] is the process of insertion of image watermark in media content and its extraction, ifrequired, for authentication or ownership verification ofmedia content. A digital image watermark is a piece of informationthat is hidden directly in media content, in such a way thatit is imperceptible to a human observer [3]. Different types of watermarkingmethods for digital contents have been developed thatare classified into different categories depending upon theuse and the requirement of information required for theextraction/detection of watermark. To check the authenticityof a digital content fragile watermarking is used while, forthe purpose of copyright protection, robust watermarking isutilized. This classification is application-dependent. Basedon the information required for the extraction/detectionprocess watermarking schemes can be classified into blind,semi-blind, and non-blind categories. Also, one more categorizationis possible depending upon the domain of embeddingof watermark: spatial and frequency. A detailed reviewof watermarking schemes can be found in [4,5]. In digital image watermarking, there will be a common problem rises at embedding phase. i.e., the optimization of embedding constant. This constant varies from image to image and also varies based on environments. Hence there is a need to optimize embedding constant such that the watermarked image must be robust and imperceptible to any type of environments. Generally, the artificial intelligence techniques such as Genetic algorithm (GA), Particle swarm optimization (PSO), Ant colony optimization (ACO) etc., techniques will be used for optimization purposes. In [6], a novel watermarking approach was proposed by combining the both GA and PSO to obtain an improved performance in watermarking criterion. However, [6] decomposes the image through the most popular Discrete wavelet transform (DWT) which is having main problem of information loss. Due to the down sampling process in DWT, the extracted watermark and also the host image can't recover entire information. Thus, the quality of the watermark will be reduced. In [7], a block based watermarking is proposed based on Discrete Wavelet Transform (DWT) and Singular Vale decomposition (DWT). Initially, the host image was divided into the blocks of size 8X8 and then processed for DWT. From the obtained sub bands, the approximation band was subjected to SVD. Similarly all blocks are processed and the largest singular value is sele...
