Fragile watermarking techniques for image authentication
, 2009 Techniques to establish the authenticity and integrity of digital images are becoming increasly essential over the Intermet. The authentication algorithm should distinguish malicious manipulations from the original watermarked image. Fragile watermarking

An Image Forensic Scheme with Robust and Fragile Watermarking for Business Documents
, 2013 This paper proposes an image forensic scheme with both robust and fragile watermarking techniques for business documents. Through a dual watermarking approach, the proposed scheme can achieve image forensics objectives of (a) identification of source; (b)

A novel fragile watermarking technique
, 2004 Several fragile watermarking techniques cannot detect vector quantization (VQ) attacks; the block-based approach, for example. Celik et al. proposed a hierarchical watermarking approach to reveal the VQ attacks.

A Fragile Watermarking and Bilinear Fuzzy Equations
, 2018 We present a fragile colour image watermarking based on the greatest solution of a bilinear fuzzy relation equation. The original image is coded with fuzzy transforms and divided in sub-images of sizes 2×2 called blocks.

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
