Steganography is a method of hiding information inside another file or message. The hidden information may be placed inside an image, audio file, video or text without making the file look unusual.

Unlike encryption, which scrambles information so it cannot be easily read, steganography hides the existence of the information itself.

Common Uses

• Hiding messages inside images.
• Sending information without drawing attention.
• Protecting sensitive information.
• Digital watermarking.
• Security research and testing.
