A Study of Steganography Approach for Securing Data in a Confidential Communication Using Encryption

Abstract

A steganography approach is a beneficial approach for hiding and encrypting messages in text, audio, video, and image formats. After the original text file is first encrypted, this encrypted file is embedded with an image file, and that image will be transferred to the recipient. The motive of this method is easy communication and transferring of files to end users safely. The intruder is the only one who can view the unhidden message which is in text, audio, video, or image format. Thus, the message is encrypted successfully. Although there are many advantages for the steganography, which also has some limitations, these issues are mainly aimed in this paper. In this chapter, the challenges of steganography are rectified with the help of securing techniques. Finally, in the results section, findings in image size and the complexity of image quality at the sender side and receiver side in one-bit, two-bit, three-bit, and four-bit steganography images are stated. Thus, steganography methods are taking progressive steps to transform this capability into higher contributions.
