Towards a metric for recognition-based graphical password security [PDF]
, 2011 Recognition-based graphical password (RBGP) schemes are not easily compared in terms of security. Current research uses many different measures which results in confusion as to whether RBGP schemes are secure against guessing and capture attacks.

A Novel (2, 3) Reversible Secret Image Sharing Based on Fractal Matrix
IEEE Access, 2020 This article first proposes two types of three-dimensional (3D) fractal reference matrices. Then, a new reversible (2, 3) secret image sharing scheme based on a fractal matrix is presented.

Image authentication using LBP-based perceptual image hashing [PDF]
Journal of Artificial Intelligence and Data Mining, 2015 Feature extraction is a main step in all perceptual image hashing schemes in which robust features will led to better results in perceptual robustness. Simplicity, discriminative power, computational efficiency and robustness to illumination changes are ...

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

Studies on the Face Authentication Using SIFT Features [PDF]
, 2012 There is ID card as the method of personal authentication. This is not necessarily a surefire way in terms of safety, forgery and loss. This is why, biometric authentication using physical features is gathering attention. Face authentication is a part of

FEBS Letters, EarlyView.We identified a systemic, progressive loss of protein S‐glutathionylation—detected by nonreducing western blotting—alongside dysregulation of glutathione‐cycle enzymes in both neuronal and peripheral tissues of Taiwanese SMA mice. These alterations were partially rescued by SMN antisense oligonucleotide therapy, revealing persistent redox imbalance as ...
