Quizplus · Accepted Answer

Insertion steganography hides data by inserting it into unused areas of the host file, which makes it difficult to detect or extract the hidden message without prior knowledge of the technique used. This is different from substitution, where the hidden data is embedded by replacing some of the content of the host file. In appending steganography, the data is added at the end of the host file, which may make it easier to detect or extract the hidden message. Replacement steganography is when the message is replaced by a visually identical cover message that conveys different information.
