Comparison of DCT, SVD and BFOA based multimodal biometric watermarking system

open access: yesAlexandria Engineering Journal, 2015
Digital image watermarking is a major domain for hiding the biometric information, in which the watermark data are made to be concealed inside a host image imposing imperceptible change in the picture.

A New Digital Watermarking Algorithm Using Combination of Least Significant Bit (LSB) and Inverse Bit

open access: yes, 2011
In this paper, we introduce a new digital watermarking algorithm using least significant bit (LSB). LSB is used because of its little effect on the image.

Digital Image Watermarking Using Ellipse Watermark

open access: yes, 2017
From past few decades watermarking became very crucial for digital images being transmitted over network. All the time ownership and license are great issues if someone fetches the image sent by one without any ownership seal, i.e. watermark, and uses as his own image.

A game-theoretic architecture for visible watermarking system of ACOCOA (adaptive content and contrast aware) technique

open access: yesEURASIP Journal on Advances in Signal Processing, 2011
Digital watermarking techniques have been developed to protect the intellectual property. A digital watermarking system is basically judged based on two characteristics: security robustness and image quality.
