A Session Based Spatial Domain Multiple Image Hiding Technique Using Variable Bit Replacement and Multiple Passwords

For hiding secret information in images, there exists a large variety of Steganography techniques. The Least Significant Bit (LSB) insertion method is the most common and easiest method for embedding messages in an image in spatial domain but it has some limitations such as it is easier to understand using steganalysis, this limitation has been overcame in this paper. This paper intends to embed multiple images in a single cover image. Three images can be embedded within a single cover image in its three different color channels (RGB) and they are embedded in between Least Significant Bit (LSB) and Moderately Significant Bit (MdSB). Three different passwords which are later converted into keys are used for three different color channels.
