The rapid development in the transfer of data through internet made it easier to transfer data accurate and faster to the destination. Security of information is one the important factors of information technology and communication. Steganography is art and science of invisible communication. Steganography is the method through which existence of the message can be kept secret. This is accomplished through hiding information in other information, thus hiding the existence of the communicated information. In this paper we are reviewing the two Steganography algorithms- Least Significant Bit and Discrete Wavelet Transformation
