Digital watermarking is a technology to hide information in digital media. We extend the digital watermarking technique Phasemark™, originally developed solely for image authent...
This study examines the feasibility of using channel statistics to perform embedded signature-based authentication. Doing so is an attempt to view a reference watermark embedded w...
—Biometric authentication is emerging as the promising solution to conventional cryptography based authentication technologies. However, protecting users’ biometric templates s...
This paper proposes a novel robust watermarking scheme to embed fingerprint minutiae into face images for multimodal biometric authentication. First, a block pyramid is layered ac...
