StegIm: Image in Image Steganography

Abstract

Today, data security is a significant problem in data communication. Sometimes we do not realize how susceptible we are to cyberattacks and the theft of critical information, including everything, from social network passwords to complete identities. Any system, no matter how sophisticated it is, is vulnerable and susceptible to attack. Steganography is a technique for hiding secret information by adding it in a non-secret file. Also, it can be used in combination with encryption to further conceal or safeguard data. Therefore, in this paper, we present the StegIm model for hiding, retrieving, and detecting images using variants of LSB Encoding Steganography. We present the implementation of the model with different algorithms for hiding the image in another image (shape steganography algorithm and standard delimiter-based steganography algorithm) and give comparison analysis of used algorithms.
