A payload distribution method for high capacity image steganography

Abstract

Steganography conceals the very existence of the message by engrafting it inside a carrier file of some type. In this paper, payload image is distributed into three different images; Normalized Error (NE), Error Factor (EF) and Sign Map (SM) by using the primary cover image. These three images are then embedded in a secondary cover image by using an existing high capacity image steganography algorithm. The experimental results show that the Normalized error (NE) and Error factor (EF) are different from payload while Sign Map (SM) contains only binary values. Therefore, No one can derive the original payload using normalized factor, error factor and sign map until s/he has a primary cover.
