What is steganography?

Steganography is the practice of concealing information within another form of data without arousing suspicion. It involves embedding secret messages, known as payloads, within seemingly harmless carriers such as images, audio files, or text documents. The main objective of steganography is to ensure that the hidden message is undetectable to anyone except the intended recipient, with the carrier appearing unchanged to the casual observer. This technique dates back to ancient times when people would hide secret information by invisible ink or by tattooing it on human scalps. Today, digital steganography techniques exploit the nature of digital files to hide information, making it an essential tool for covert communication, privacy protection, and digital forensic investigations.
