Critical Review of Video, Audio, Image and Text Steganalysis Technique for Digital Forensics

Abstract

In terms of security systems and digital forensics, steganography and steganalysis are relatively young fields of study, but they have advanced significantly over the past 20 years. In any field of human endeavor, it is necessary to periodically pause and assess the discipline state for what has been accomplished thus far. Steganography seeks to conceal messages, but steganography analysis seeks to either find them or, more importantly, recover the data they contain. Steganography and stegananalysis piqued the interest of many people, particularly law enforcement. Steganography is often used by cybercriminals and even terrorists to avoid being apprehended while in possession of encrypted incriminating evidence, even though cryptography is prohibited or restricted in many countries. A systematic strategy was used to find pertinent studies on video, audio, image, and text steganography in the Web of Science (WOS) All Database and the Scopus database. In Scopus and the Web of Science (WOS), all database search phrases were entered with the language set to English. The research presented software tools and techniques for text steganalysis, which make it simple to find concealed information in picture, audio, and video steganalysis. Future directions for the steganalysis technique for text, audio, video, and image steganography were highlighted in the paper.
