Reversible fragile watermarking scheme for three-dimensional models
, 2014 Watermarking is a very important technique for protecting the authorization of digital content, such as still images, video streams, audio streams, and 3-D models. Most fragile watermarking schemes for 3-D models are not reversible.

Improve security of fragile watermarking via parameterized wavelet
, 2004 The security is an important issue in watermarking. It has not, however, received enough attention yet. In this paper, we propose a secure fragile watermarking algorithm based on parameterized integer wavelet transform, and the rational range of the ...

A Study on Fragile Watermarking Algorithms for Three Dimensional Models
, 2014 浮水印技術(watermarking schemes)已被廣泛地使用在保護傳統的數位媒體，例如：影像、視訊、音訊、以及三維模型(3D models)等。相較於其他眾多不同媒體型態，三維模型(3D models)浮水印技術基本上顯得比較困難。近年來在三維模型偽裝術(steganography)及強韌浮水印技術(robust watermarking)領域上有相當多的進展，然而僅有少數的學者對碎形浮水印技術(fragile watermarking)作相關的研究。在已發表的三維模型碎形浮水印技術 ...

Fragile Watermarking Scheme for Digital Image Authentication Using Pixel Difference
, 2009 [[abstract]]The article presents a novel fragile watermarking scheme based on the concept of pixel differencing for the integrity verification of digital images. The scheme uses the human visual system to embed the authentication data into the difference
