Image watermarking is an effective and promising technology. Robust watermarks, resistant
to various attacks, allow authors and owners of digital images to protect their rights to digital …

This paper proposes a novel image authentication scheme in the wavelet domain. The
scheme uses a semi-fragile watermark to detect and precisely locate malicious tampering in …

Among the renewable forms of energy, solar energy is a convincing, clean energy and
acceptable worldwide. Solar PV plants, both ground mounting and the rooftop, are …

ABSTRACT A blind digital image watermarking scheme based on spatial domain is
presented and investigated in this paper. The watermark has been embedded in …

Based on the fixed point theory, this paper proposes a new scheme for image integrity
authentication, which is very different from digital signature and fragile watermarking. By the …

The rapid development of the Internet and digital image modification software has invited the
illegal access to and use of digital images. In response, digital watermarking has emerged …

In this paper a robust technique for video watermarking (VW16F) is proposed and the design
and implementation of the proposed technique are discussed. The VW16F technique is …

To achieve robustness and imperceptibility, an adaptive compressed domain blind video
watermarking method based on Discrete Wavelet Transform (DWT) is proposed in this …

In this paper, we propose a digital watermarking method for still images, in which the human
visual system (INS) is used in the discrete cosine transform (DCT) domain. The modulation …

提出一种基于单图像局部置乱和动态反馈的混沌图像加密算法. 首先, 提出一种单图像局部置乱
算法. 其次, 在扩散阶段, 采用一种基于动态反馈的扩散策略来改变置乱后图像中的像素值 …
