Digitally embedding a message into a cover-medium usually involves three basic steps. First, the redundant bits of the target cover-medium must be identified. Second, it must be decided which of the identified redundant bits are to be utilized. Finally, the bits selected for use must be modified to store the message data. In many cases, a cover-medium's redundant bits are likely to be the least-significant bit or bits of each of the encoded data's word values.
