Fusion of LSB and DWT Biometric Watermarking Using Offline Handwritten Signature for Copyright Protection

摘要: Biometric watermarking was introduced as the synergistic integration of biometrics and digital technology. This paper proposes a novel biometric technique, which embeds offline handwritten signature in host image for copyright protection. We propose to combine conventional LSB-based DWT-based techniques into unison framework, is known LSB-DWT this paper. The proposed technique evaluated against various simulated security attacks, i.e. JPEG compression, Gaussian low-pass filtering, median noise, scaling, rotation cropping. experimental results demonstrate that exhibits remarkable watermark imperceptibility robustness.
