Modulo Based Image Steganography Technique Against Statistical and Histogram Analysis

Steganography is the art and science of communicating secret data by embedding it into a multimedia carrier. The ultimate goal here is to conceal the very existence of the embedded data. Although the term Steganography has been known for thousands of years, its digital version came about only lately and research was intensified after the depressing event of Twin towers. Steganalysis, which is the official counter attack science, defeats Steganographic algorithms whether they are based on the traditional spatial domain or the transform one. Steganography's ultimate objectives, which are undetectability, robustness and capacity of the hidden data, are the main factors that separate it from other relating techniques, namely watermarking and cryptography.
