Abstract

In this paper we propose a new technique in steganography to hide the information to be hidden with digital image. Here we take BMP image to hide the data. We take most common Steganography algorithm LSB as base and made some changes in it based upon our innovative idea that is integration of first LSB algorithm and second LSB algorithm. We consider here security as main aspect. So, we also apply randomization concept for selecting the pixel in image to hide data. Random values are generated upon secret key. Hackers cannot find random numbers unless they have key with them. Detailed visual and statistical analysis of the algorithm reveals that it yields satisfactory results. When compared with other existing algorithms, it is easy to prove that the difficulty of decoding the proposed algorithm is high.
