First International Symposium on Cyber Worlds, 2002. Proceedings., 2003
There is an increasing number of products to be saved in digital form. In the digital world, we can preserve products forever, but there are also disadvantages such as easy copying. The watermark is an important protection method in digital media. When a media is publicly available or put on a network, it is very easy to copy or be misappropriated. The

Directional Watermarks in Images
2005 IEEE International Symposium on Circuits and Systems, 2005A new watermark scheme based on directional filter banks and wavelet subband decomposition techniques is proposed. In order to embed the mark into the directional subband images, a projection classification algorithm is presented. These subband images with a particular directional property can prevent unauthorized use attacks.

Progressive image watermarking
2000 IEEE International Conference on Multimedia and Expo. ICME2000. Proceedings. Latest Advances in the Fast Changing World of Multimedia (Cat. No.00TH8532), 2002Progressive transmission of images is very useful in many applications, especially in image transmission over the Internet. To view an image, people would want to see part of the image while the image transmission is in progress, rather than having to wait until the end of the image transmission.

Proceedings 2003 International Conference on Image Processing (Cat. No.03CH37429), 2004
In this paper we present a reversible watermarking technique for digital images. In our context, reversibility refers to the ability to restore the original image by the watermark detector. The technique is based on a transformation function that introduces 'gaps' in the image histogram. The 'gaps' are used to encode the watermark.

Geometric Invariance in Image Watermarking
IEEE Transactions on Image Processing, 2004Surviving geometric attacks in image watermarking is considered to be of great importance. In this paper, the watermark is used in an authentication context. Two solutions are being proposed for such a problem. Both geometric and invariant moments are used in the proposed techniques.

Cocktail Watermarking on Images
2000A novel image protection scheme named “cocktail watermarking” improves over current spread-spectrum watermarking approaches. Two watermarks, which play complementary roles, are simultaneously embedded into an original image. The new watermarking scheme has the characteristic that, no matter what an attack is, at least one watermark typically survives ...

Multichannel watermarking of color images
IEEE Transactions on Circuits and Systems for Video Technology, 2002In the field of image watermarking, research has been mainly focused on grayscale image watermarking, whereas the extension to the color case is usually accomplished by marking the image luminance, or by processing each color channel separately. A DCT domain watermarking technique expressly designed to exploit the peculiarities of color images is ...

Audio Watermarking with Multiple Images as Watermarks
IETE Journal of Education, 2020Nowadays, the security of information has become a burning question. Digital watermarking can be very efficient in providing security of a signal being sent. In this paper, a digital watermarking technique for ensuring security to an audio signal is presented.

Adaptive Watermarking Algorithm for Binary Image Watermarks
2004This paper proposes an adaptive watermarking algorithm, in which the watermark is a binary image such as a logotype related directly to the image owner. Obviously the information amount of this type of watermark is much larger than the amount of a pseudorandom pattern generated by secret key.
