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 …

We propose a fragile watermarking scheme in the wavelet transform domain that is sensitive
to all kinds of manipulations and has the ability to localize the tampered regions. To achieve …

Healthcare organizations are undergoing tremendous change in analytical computing. The
vehicle for this change is implementing a Business Intelligence (BI) platform, which includes …

Digital media manipulation has become easily performed at personal level with the rapidly
growth of Technology. Presenting an issue of protecting digital media integrity …

针对目前脆弱水印算法大多无法区分水印被篡改还是内容被篡改的问题, 本文基于多重水印技术
提出了一种能区分水印或内容篡改的脆弱水印算法. 该算法由子块的主要DCT …

摘要针对脆弱水印认证算法的篡改定位精度及安全性问题, 提出了一种将篡改检测和定位分离的
图像认证方案: 对图像进行单像素置乱并将其低两位置零, 采用像素关联技术生成各个像素的 …

Watermarking schemes for authentication purposes are characterized by three factors:
security, resolution of tamper localization, and embedding distortion. Since the requirements …

In this paper we propose a novel watermarking scheme for image authentication. A high
localization of tampering detection is achieved by applying a random permutation process …

This paper presents an authentication watermarking method which can localize the
tampering regions in fine granularity. Unlike the previous block-wise tampering-localization …
