In this paper, we develop a robust image data hiding scheme based on multiple description coding of the signature image. At the transmitter, the signature image is encoded by balan...
In this paper, we propose a new method for hiding a signature image in the host image. We encode the signature image by a balanced two-description subband coder and embed the descr...
In this paper, we propose a methodology for embedding watermark image data into color images. At the transmitter, the signature image is encoded by a multiple description encoder. ...
In this paper we present a robust and novel strategic invisible approach for insertion-extraction of a digital watermark, a color image, into color images. The novelty of our sche...

—We consider a method for preventing e-Fraud in which a binary image is encrypted with a floating point cipher using a convolution operation and the output quantized into a 1-bi...
