Abstract- Data encryption is not the only safe way to protect data from penetration given the tremendous development in the information age particularly in the field of speed of the processors and the cryptanalysis. In some cases, we need new technologies or methods to protect our secret data. There has emerged a set of new technologies that provides protection with or without data encryption technology such as data hiding. The word steganography literally means ‘covered writing’. It is derived from the Greek words “stegos ” meaning “cover”, and “grafia” meaning “writing”. Steganography functions to hide a secret message embedded in media such as text, image, audio and video. There are a lot of algorithms used in the field of information hiding in the media; the simplest and best known technique is Least Significant Bit (LSB). In this paper we have made a comparison and of the (LSB) algorithm using the cover object as an image. From this image, we have chosen two types: Gif and BMP. The comparison and is based on a number of criteria to find out the strengths and weaknesses when using any of the two types.
