As the substantial challenge in providing security of digital images is owners authentication in many security schemes based on cryptography, steganography and watermarking technology, biometric recognition methods are introduced. In the sequel to these studies in presented methodology the combination of biometric recognition methods based on facial images with watermarking technology to perfor...

An ideal watermarking scheme is a technique of embedding secret information into the image in order toauthenticate the image. This helps in detecting The integrity of the image. Here a block based Watermarking technique has been sed. A Fuzzy C means based algorithm is used here to Watermark and authenticate the image Experimental result here show that it can detect maximum modification and it c...

Watermarking is one of the best solutions for copyright protection and authentication of multimedia contents. In this paper a hybrid scheme is proposed using wavelet and shearlet transforms with singular value decomposition. For better security, Arnold map is used for encryption. Examining the results and comparing with other methods show that this hybrid proposed scheme with simultaneous utili...

This paper presents a hybrid image watermarking technique for data hiding on high entropy areas of an image. The basic idea of proposed technique is based on embedding of watermark in original image using hybrid DWT SVD watermarking algorithm to produce watermarked image. Then performance of proposed algorithm will be analyzed and compared with existing DWT SVD technique which has been applied ...

-Based on the statistical characters of remote sensing image, this paper proposed firstly partition remote sensing image into sub-block images of suitable sizes, and then decomposing these sub-block images with biorthogonal 7/5 wavelet. A novel construction method of wavelet set of coefficients is adopted to embed binary watermarking image into sub-bands except low frequency sub-bands, and real...

Digital watermarking of multimedia content has become a very active research area over the last several years. Watermarking is a very important field for copyrights of various electronic documents and media. With images widely available on the Internet, it may sometimes be desirable to use watermarks. Digital watermarking is the processing of combined information into a digital signal. A waterm...

We propose an improved autocorrelation function (ACF)based image watermarking that is robust to combined geometric and removal attacks. ACF-based watermarking is thought of as one of the most effective watermarking schemes that resist geometric attacks. In this watermarking scheme, the autocorrelation peaks of the watermark play an important role for geometric attack estimation. The peaks, howe...

Because of the large amount of frames, similarity between frames and temporal attacks (frame dropping, frame averaging, frame swapping etc.), the process for video watermarking is more difficult than that for image watermarking. Current image watermarking methods are limited to solve all these difficulties. We propose a novel video watermarking system based on the Hidden Markov Model (HMM). Thi...

Image watermarking has proven to be quite an efficient tool for the purpose of copyright protection and authentication over the last few years. In this paper, a novel image watermarking technique in the wavelet domain is suggested and tested. To achieve more security and robustness, the proposed techniques relies on using two nested watermarks that are embedded into the image to be watermarked....
