Esteganografia: a arte de esconder informações

Abstract

This work takes an approach on Information Security and describes the Steganography as mechanisms used in the protection of information and its mechanisms. The work focuses on an information protection approach using a Steganography protection mechanism, in which a demonstration tool has been implemented that inserts short messages into image files. The purpose of this tool is to demonstrate the concealment of information in digital images, using Steganography. The Last Significant Bit Steganography (LSB) method was used to conceal the information in a user-defined image of the system. This tool demonstrates the introduction of an imperceptible form to the human being (vision), in such a way that the detection by third parties is unlikely, as well as the guarantee of almost unalterable recovery of the message. Based on Steganography schemes and according to the results obtained from other works analyzed in this work, the feasibility of the development of applications to guarantee the authenticity, the confidentiality and the protection of information transmitted by the web is evaluated
