Block mapping and dual-matrix-based watermarking for image authentication with self-recovery capability. [PDF]

open access: yesPLoS ONE
Numerous image authentication techniques have been devised to address the potential security issue of malicious tampering with image content since digital images can be easily duplicated, modified, transformed and diffused via the Internet transmission ...

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.

A reversible and lossless secret image sharing scheme with authentication for color images

open access: yesJournal of King Saud University: Computer and Information Sciences, 2023
With the increasing concern for public privacy protection, Secret Image Sharing (SIS) has garnered significant attention among researchers. The goal of SIS is to split a secret image into multiple shadows, rendering it unrecoverable unless a specific ...

Digital watermarking for image authentication with localization

open access: yes, 2022
S.1973-1976In 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 where every embedded watermark bit verifies random image positions ...

A Survey on Image Hashing for Image Authentication

open access: yesIEICE Transactions on Information and Systems, 2010
The traditional cryptographic hash functions are sensitive to even one-bit difference of the input message. While multimedia data always undergo compression or other signal processing operations, which lead to the unsuitability of multimedia authentication using cryptographic hash. The image hashing has emerged recently which captures visual essentials
