Moderate Bit Insertion for Hiding Crypto-Data in Digital Image for Steganography
The simplest method based on Least-Significant-Bit (LSB) substitution embeds important data in the least significant bits of the cover image. The LSB method introduces a small distortion in the cover image. Many data hiding techniques are focused usually to reduce the distortion in the cover image when sensitive data is embedded into the same. However, post processing of stego-image or its transmission may cause serious errors in the information being carried by stego-image. The receiver cannot extract the correct information from the stego-image having any such type of distortion.
