| Titre | L'art secret de la stéganographie The Covert Art of Steganography |
| Texte | The content of this post is solely the responsibility of the author. AT&T does not adopt or endorse any of the views, positions, or information provided by the author in this article. In cybersecurity, where information is both an asset and a potential target, various techniques are used to secure data and communications. One such covert art is steganography, which hides information within seemingly innocuous files to avoid detection. This article dives into the fascinating world of steganography, its history, techniques, and applications in the digital age. Understanding steganography Steganography, derived from the Greek words "steganos" (meaning covered) and "graphy" (meaning writing), is the art of concealing information within other data in a way that is not easily noticeable. Unlike cryptography, which seeks to make information unreadable, steganography aims to hide the existence of the information itself. Historical roots Steganography can be traced back to ancient times when people sought secure means of communication. Tattooing messages on shaved heads was one of the earliest recorded uses, allowing messengers to transmit information undetected. Another historical example is using invisible ink to write hidden messages during wartime. Digital steganography Steganography has evolved into a sophisticated practice in the digital age, utilizing the vast amounts of data exchanged on the internet. Digital steganography is the process of hiding information within digital media, such as images, audio files, and even executable files. The goal is to render the hidden data invisible to both human observers and automated tools. Digital steganography techniques Image steganography: |
