Steganography
Steganography is the practice of concealing information within other non-secret data, such as hiding a message within an image, audio file, or video. Unlike cryptography, which focuses on making data unreadable, steganography aims to make the existence of the data undetectable. It is commonly used in digital security, watermarking, and covert communication to protect sensitive information from unauthorized detection.
Developers should learn steganography when building applications that require secure, hidden data transmission, such as in digital rights management, secure messaging systems, or forensic analysis tools. It is particularly useful in scenarios where encryption alone might draw suspicion, as it allows data to be embedded in innocuous-looking files like images or audio, enhancing privacy and security in sensitive communications.
