Steganography and Steganalysis are two side of the same coin. This paper discuss about how a message or data can be hidden inside an image using JPEG Steganography. Along with this, RC5 encryption and Chaos cryptography are also used so that, an outsider is not able to access the data within the image. This paper also discuss about how a data is stored or hidden inside an image and how we can recover data from the same image. This type of systems are made to make our applications and data more secure from the threats. This paper focus on using lifting wavelet transform (LWT) instead of using old methods like DCT.
