The incredible evolution of Internet technologies & its applications requires high level of security for data over the unsecured communication channel.This paper presents steganography technique using 2 x-box mapping technique.Image steganography is a skill of hiding the information in a cover image in such a way that only intended recipient can know that there is a hidden message.Least Significant-Bit (LSB) based approach is most common Steganographic techniques in spatial domain due to its simplicity and robustness, hiding embedding capability.In this paper a new technique is implemented based on LSB for Image steganography using 2 X-box mapping.In an existing method for hiding the secret data in the LSB substitution method four X-boxes are used to hide two secret bits in each pixel of the cover image.In this method using two X-boxes, 4 bits of secret message is hidden.This enhances the security of the secret message, with no movement of the PSNR value of the cover image. .
