A second generation Visual Secret Sharing scheme for color images

A novel, cost effective visual secret sharing (VSS) scheme is introduced in this work. The scheme partitions the input image into sub-components by utilizing a segmentation step. The contents of the segmented parts are subsequently used to form a secret sharing solution. This modular approach, which mimics the second generation coding principles, affords perfect reconstruction. Comparisons and experimental results included here indicate that it also compares very favorably against competing solutions when it comes to pixel expansion.
