Computação forense e a técnica de esteganografia aplicada em imagens digitais: um mapeamento sistemático

Abstract

Along with the evolution of technology, crime advances in digital forms, attacking software of companies, institutions, and individuals. New forms of attack, techniques, and tools arise to increase the work of computer forensics, which seeks technological evidence that elucidates the facts in investigations of illicit acts in the digital environment through technical-scientific methods. Therefore, this study presents the results of a systematic mapping of the literature on the methodologies, tools, and software related to computer forensics, in order to synthesize the available studies and to assess the state-of-the-art on the subject. The steganography is one of the arising techniques used in computational crimes, and it can be applied to files such as images, videos, and audios. Due to its current relevance, the identification technique of steganography in digital images is also pointed out in this paper.
