TDSF: Two-phase tamper detection in semi-fragile watermarking using two-level integer wavelet transform [PDF]
Image watermarking is one of techniques that can be used to protect and recover from the altered images. Tamper detection in semi-fragile still does not achieve high accuracy for tamper localization, especially in malicious attacks.

A tamper detection scheme based on integer wavelet transform for authenticating image [PDF]
Advanced technology allows users to alter image and distribute the tampered image to social media. This research proposes a set level of tamper detection for identifying the integrity of image. The image is transformed by using integer wavelet transform (

Image Hash Minimization for Tamper Detection
Tamper detection using image hash is a very common problem of modern days. Several research and advancements have already been done to address this problem. However, most of the existing methods lack the accuracy of tamper detection when the tampered area is low, as well as requiring long image hashes.

Tamper Detection and Continuous Non-malleable Codes [PDF]
WeN consider a public and keyless code (Enc,Dec) which is used to encode a message m and derive a codeword c = Enc(m). The codeword can be adversarially tampered via a function \(f \in{\mathcal F}\) from some “tampering function family” \(\mathcal F\), resulting in a tampered value c′ = f(c). We study the different types of security guarantees that can

A BLIND WATERMARKING SCHEME FOR TAMPER DETECTION IN DIGITAL IMAGES [PDF]
The paper proposes a method for tamper proofing digital images using the technique of digital watermarking. Many a times the published images are subject to tampering to an extent that the facts conveyed in the original image are distorted. The mechanism
