Abstract: Information hiding recently become an important area in many applications, and the large demand of internet implementations requires data to be transferred in a secure state, there are many techniques of Information hiding exist for the securing process. The aim of this paper is to compare the hiding of information in images by the least significant bit ‘LSB’. This done through inclusion of the secret message inside the image file in a complex form, so that as to make the finding of scattered information inside the image difficult, by using BMP, PNG and JPEG image format. In order to increase the security of the algorithm.

Keywords: Steganography, Information hiding, Cover image, Least Significant Bit (LSB), Stego image, spatial domain, security.
