Two-Layer Fragile Watermarking Method Secured with Chaotic Map for Authentication of Digital Holy Quran [PDF]

open access: yesThe Scientific World Journal, 2014
This paper presents a novel watermarking method to facilitate the authentication and detection of the image forgery on the Quran images. Two layers of embedding scheme on wavelet and spatial domain are introduced to enhance the sensitivity of fragile ...

Image Fragile Watermarking through Quaternion Linear Transform in Secret Space [PDF]

open access: yesJournal of Imaging, 2017
In this paper, we apply the quaternion framework for color images to a fragile watermarking algorithm with the objective of multimedia integrity protection (Quaternion Karhunen-Loève Transform Fragile Watermarking (QKLT-FW)).

Digital fragile watermarking scheme for authentication of JPEG images [PDF]

open access: yes, 2004
It is a common practice in transform-domain fragile watermarking schemes for authentication purposes to watermark some selected transform coefficients so as to minimise embedding distortion.

Wavelet-based fragile watermarking scheme for image authentication [PDF]

open access: yes, 2007
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.

Digital watermarking scheme exploiting non-deterministic dependence for image authentication [PDF]

open access: yes, 2006
Watermarking schemes for authentication purposes are characterized by three factors: security, resolution of tamper localization, and embedding distortion.

Applying interest operators in semi-fragile video watermarking

open access: yes, 2022
S.353-362In this article we present a semi-fragile watermarking scheme for authenticating intra-coded frames in compressed digital videos. The scheme provides the detection of content-changing manipulations while being moderately robust against content ...

A novel semi-fragile forensic watermarking scheme for remote sensing images [PDF]

open access: yes, 2011
Peer-reviewedA semi-fragile watermarking scheme for multiple band images is presented. We propose to embed a mark into remote sensing images applying a tree structured vector quantization approach to the pixel signatures, instead of processing each band ...

A fragile watermarking scheme for 3D meshes [PDF]

open access: yesProceedings of the 7th workshop on Multimedia and security, 2005
In this paper, we propose a new fragile watermarking scheme for 3D meshes. Firstly, the watermark information is adaptively embedded into the mesh geometry by slightly adjusting the vertex positions while the mesh topology is unchanged. The embedded watermark can be blindly retrieved with some priori knowledge and used to authenticate the integrity of ...

Reversible watermarking scheme with image-independent embedding capacity [PDF]

open access: yes, 2005
Permanent distortion is one of the main drawbacks of all the irreversible watermarking schemes. Attempts to recover the original signal after the signal passing the authentication process are being made starting just a few years ago. Some common problems,
