This is age of fast communication and data revolution. Huge amount of data is transmitted and received in every second utilizing the current infrastructure. Providing the security and maintaining integrity of the data while it is being transferred through the public channels is a challenging task. Steganography can be used in this purpose by concealing the data inside text, image, audio or video file formats and send the files to the other end. This paper gives an overview of various image steganography methods. To hide secret information in images various steganographic methods are available which have their own pros and cons. In this paper we have discussed the types of image steganography. Here we propose two different image steganography methods using Modified Least Significant Bits (LSB) and Discrete Wavelet Transform (DWT) methods. Also, the results are analyzed using different parameters like Peak signal to noise ratio(PSNR), Mean Square Error(MSE) to find out the efficiency of the proposed methods
