Visual cryptography is a secret sharing technique mainly used for image sharing. In the case of extended visual cryptography we use meaningful shares to hide image. Contrast loss in decrypted image is a major problem. Here we use Additional basis matrix and perfect white pixel reconstruction to improve the contrast in color extended visual cryptography.

As an integrated part of a supply contract, trade credit has intrinsic connections with supply chain contracting and inventory management. Using a stylized model that explicitly captures the interaction of firms’ operations decisions and financial risks, this paper attempts to develop a deeper understanding of trade credit from an operational perspective. Revolving around the question of what r...
