Definition: Steganography is a technique used to hide information or data in digital media, such as text files or images, by using software tools and techniques. It involves encoding data within the file's structure or content rather than directly in the file itself. This method allows for the non-visual representation of information without the need for physical storage or display. Steganography can be used to protect sensitive information from prying eyes or to create visually appealing images that are difficult to decipher by others.
