What are the types of steganography techniques?

Steganography techniques can be broadly classified into four main types based on how they embed hidden information within a carrier medium. The first type is known as substitution techniques, where bits or characters in the carrier medium are exchanged or replaced with the hidden information. The second type is known as transformation techniques, which involve modifying certain properties of the carrier medium, such as changing the color intensity of pixels in an image, to embed the hidden information. The third type is known as insertion techniques, where the hidden information is inserted into unused or insignificant portions of the carrier medium. Finally, the fourth type is known as cover generation techniques, where a new carrier medium is generated specifically to carry the hidden information, such as creating a new image or audio file. These various types of steganography techniques provide different approaches for hiding information, offering flexibility and adaptability in different scenarios.
