Moderate Bit Insertion for Hiding Crypto Data in Digital Image for Steganography

The simplest method least-significant-bit (LSB) substitution embeds the important data in the least significant bits and introduces small distortion into the pixels of cover image. Many data hiding techniques mainly focused to reduce the distortion of cover image when sensitive data is embedded into the cover image. It also prevents the visual quality degradation of cover image. However, the post processing of stego image or stego image occur transmitting errors. The receiver cannot extract the correct information from the stego-image having any such type of errors. To overcome these problems, a novel method for crypto data hiding within grey scale
