Abstract

In this paper we propose a novel method based on Inverse Transitions for increasing the security of Least Significant Bit (LSB) replacement steganography. Before hiding data using LSB replacement, cover image is preprocessed using inverse transitions. The preprocessing modifies the LSBs in such a way that the resulting change in pixel values can not occur with LSB replacement. The proposed method ensures 100% undetectability for payload up to 1.5 bpp in colour images against most accurate length estimation methods for LSB replacement. The proposed method is faster, does not require any additional storage and ensures complete recovery of hidden data in comparison to state of the art steganography methods. The proposed method can be used in resource constrained applications which demand fast and secure data hiding and loss less recovery of hidden data.
