Cordially invites you to attend an open lecture on:

Visual Cryptography Scheme - A Brief Survey

by
Dr.S.Arumugam
National Centre for Advanced Research in Discrete Mathematics (n-CARDMATH) Kalasalingam University and Conjoint Professor School of Electrical Engineering and Computer Science The University of Newcastle

Date: Monday, November 14th, 2011
Time:6:00 pm 7:00 pm (free admission)
Venue: BUiD Auditorium, 1st Floor, Block 11, Dubai International Academic City

The lecture will discuss the following:

Let P be a set on n elements, called participants. Consider a secret image which consists of black and white pixels. A (k,n) - Visual Crptography Scheme is a method of constructing n shares of the secret image, one for each participant, in such a way that the secret image can be reconstructed from k or more shares but not from less than k shares. The process of reconstruction is purely visual in the sense that if each share is xeroxed on a transparency, the recovering of the image is just by stacking the respective transparency sheets. In this talk we give a brief survey of Visual Crptography Scheme and its applications.
