Data transmission secrecy is important as more and more people are joining the online world.The focus behind data security is to ensure privacy while protecting personal or business data.This demands the need to revamp techniques in the ancient science of steganography. Steganography is the art of concealing data in a manner that its existence itself cannot be detected. This demands the need to revamp techniques in the ancient science of steganography.This Proposed method aims to hide text data within an image, popularly known as image steganography.Transform domain technique is selected for hiding data taking into consideration its advantages over spatial domain image steganography. Our objective is to build stego-image that shoudnt be susceptible to steganalysis.Once user enters the secret data to be hidden it gets convert into secret image. Text data within this secret image is not visible to the naked eyes.This secret image is further hidden into cover image which ultimately gives stego-image. Performance metrics were used to evaluate the quality of the stego-image as well as the extracted secret data. Experimental results indicate that the proposed techniques produce stego- images that are highly imperceptible.
