Hide text in images using steganography and a review of methods and approach for secure stegnography

In this paper, we have proposed a new steganographic algorithm that is used to hide text file inside an image. In order to increase/maximize the storage capacity we have used a compression algorithm that compresses the data to be embedded. The compressi on algorithm we have used works in a range of 1bit to 8 bits per pixel ratio. By applying this algorithm we have developed an application that would help users to efficiently hide the data. In this paper we also survey different steganography techniques for encrypting the data. Steganography is a technique that allows the one to hide the data within an image while adding few noticeable changes. This paper discusses the concept behind the steganography by exploring firstly what is the steganography and the terms that are related to steganography. This paper explores the steganography methods-image steganography, audio steganography, video steganography, text steganography that are used to embed the information in digital carriers. The two most important aspects of image based stegnography system are the quality of stego image and the capacity of the cover image. By reviewing this paper, researchers can develop a better steganography technique to increase the MHC and PSNR value by analyzing the existing steganalysis techniques.
