Digital media is a craze these days. With the present day Internet connectivity the world has become smaller. The copyright protections of intellectual properties have become a necessity for prevention of illegal copying and content integrity verification. Newer data hiding techniques that satisfy the requirements of imperceptibility, robustness, capacity, or data hiding rate and security of the hidden...
The proliferation of the digitized media introduces an exigent problem of security in multimedia data transmission in the network surroundings. Consequently, digital watermark technique needs to be incorporated in a digital rights management framework to address different aspects of the content management. The objective is to develop low power, real time, reliable and secure data hiding system that...
The explosion of the digitized media introduces a demanding problem of security in multimedia data communication in the network environment. Accordingly, digital watermarking technique needs to be integrated in a digital rights management framework to address different features of the content management. The purpose is to build up low power, real time, reliable and secure data hiding system that can...
The current paper presents a robust watermarking method for still images, which uses the similarity of discrete wavelet transform and human visual system (HVS). The proposed scheme makes the use of pixel wise masking in order to make binary watermark imperceptible to the HVS. The watermark is embedded in the perceptually significant, spatially selected detail coefficients using sub band adaptive threshold...
