Active attacks and natural impacts can lead to two types of image-container distortions:
noise-like and geometric. There are also image processing operations, eg scaling, rotation …

This paper introduces two robust and optimized watermarking techniques designed to
protect the copyright of color digital images. These techniques involve embedding a …

This paper presents a high payload watermarking method for audio signals to accommodate
biometric based watermarks generated from iris images. The watermark generated from …

This paper presents a method of imperceptibly inserting a biometric-based digital watermark
generated from iris image in an audio signal. The use of biometric features as a watermark is …

This paper proposes an audio watermarking algorithm having good balance between
perceptual transparency, robustness, and payload. The proposed algorithm is based on …

This paper proposes a method to establish joint ownership of digital images by embedding
imperceptible digital pattern in the image. This digital pattern is generated from biometric …

This paper is aimed to address the issue of ownership rights of digital data like images and
audio signals. This is achieved by inserting a perceptually transparent unique digital pattern …

This paper proposes a method of inserting a digital pattern having patient identity
information in the medical retinal image without changing the perceptual property and …

This paper addresses the issue of ownership of digital images by embedding imperceptible
digital pattern in the image. The digital pattern is generated from multiple biometric features …

This paper addresses the issue of joint ownership of digital images and audio signals by
embedding a perceptually transparent digital signature. The pattern is generated using an …
