Abstract
An aspect ratio invariant visual secret sharing (ARIVSS) scheme is a perfectly secure method for sharing secret images, by expanding a secret pixel to m sub pixels in shadow images, with m being the pixel expansion; meantime the aspect ratio of the recovered secret image is fixed. The advantage of ARIVSS is that there is no loss of information when the shape of the secret image is our information; for example, a secret image of a circle is compromised to an ellipse, if m does not have a square value. Two ARIVSS schemes, based on processing one and four pixel blocks, respectively, were previously proposed. In this paper, we have generalized the square block-wise approach, to further reduce pixel expansion.
