Executive Summary

In this paper, the authors aim on transferring the data in a more secured manner using WPC. Cryptography and Steganography techniques of encrypting the data and hiding the data are well known. In this paper, they use Wet Paper Codes (WPCs), which enable the sender to determine the selection channel freely, and the recipient to extract the embedded messages without any knowledge about the selection channel. WPCs have been used in various branches of information hiding. WPC is a model of embedding messages into a cover with defective cells. Taking the image as an example, they denote changeable pixels by dry positions and defective pixels by wet positions.
