Visual Cryptography for General Access Structures
, 1996 A visual cryptography scheme for a set P ofnparticipants is a method of encoding a secret imageSIintonshadow images called shares, where each participant in P receives one share. Certain qualified subsets of participants can “visually” recover the secret

An XOR-Based (k, n) Visual Fully Independent Secrets Sharing Scheme with Meaningful Shares
Applied SciencesWith the rapid advancement of technology, data transmission security has become an increasingly critical issue. Visual Cryptography Scheme (VCS) provides a secure method for sharing secret images without complex computation—by stacking multiple shares ...

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Background and Purpose White matter hyperintensities (WMH) are a core neuroimaging marker of cerebral small vessel disease (CSVD). Sleep apnoea (SA) is a recognized vascular risk factor, but its associations with regional WMH burden, short‐interval WMH change and cognitive performance in population‐based cohorts remain incompletely defined. We

A Visual Cryptography Scheme with an Artificial Cocktail Party Effect
, 2011 Con el fin de codificar y ocultar un determinado conjunto de imágenes en escala de grises, este trabajo propone un esquema extendido de criptografía visual en el cual el proceso de decodificación simula un efecto cocktail party, debido a que con el uso

Memory and Resting‐State Connectivity in Acute Transient Global Amnesia: A Case–Control fMRI Study
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Background and Objectives Transient global amnesia (TGA) is a striking model of isolated amnesia. While hippocampal lesions are well described, the network‐level mechanisms and the precise neuropsychological profile remain debated. Our objective was thus to characterize functional and neuropsychological correlates of acute TGA and their ...

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Isolated rapid eye movement sleep behavior disorder (iRBD) is a prodromal state for Lewy body disorders and exhibits biological heterogeneity that may influence clinical expression and progression. We examined clinical features in individuals with iRBD and biomarker‐defined synucleinopathy.

Constructions of Visual Cryptography Schemes.
, 2004 Visual cryptography is a secrei sharing scheme in which the secret is an image. The image could be a page of printed texc, a photograph, a picture, etc. A visual cryptography scheme enables an image to be split into a number of shares that are printed on
