This paper presents a real-time image tamper detection and localization based on fragile
watermarking and Faber-Schauder discrete wavelet transform (FSDWT). The maximum …

Problem statement: In recent years, as digital media are gaining wider popularity, their
security related issues are becoming greater concern. Method for authenticating and …

This paper presents two fragile watermarking schemes for tamper localization in digital
images. In the first scheme, the unprotected image is divided into 8× 8 blocks. A 128 bit hash …

This paper presents a fragile watermarking scheme for tamper localization using Singular
Value Decomposition (SVD) and logistic map. The proposed scheme divides the image into …

A new discrete wavelet transform-based image fragile watermarking scheme exploiting the
features of the human visual system is presented. Fusion of multi-resolution tamper …

In this paper, we analyze the security of a semi-fragile watermarking scheme recently
proposed by N. Sivasubramanian et al. for tamper detection and recovery in digital images …

Protection of intellectual property rights has become one of the focuses of social concerning.
To reduce those disputations, the watermark is implanted into the media by the content …

The continuous development of forgery attacks on critical multimedia applications
necessitates having accurate image tamper detection and localization techniques. In this …

In this paper, two logistic-map based fragile image watermarking schemes are proposed.
The first scheme is a conventional irreversible, whereas the second scheme is a reversible …

Ensuring the image content authentication is a necessity need when images are used as
supporting evidence in critical applications such as law enforcement, medical diagnosis …
