Digitally Embedding

Digitally embedding a message in a cover-medium usually involves two steps:

Identify the redundant bits of a cover-medium

Deciding which redundant bits to use and then modifying them

Generally, redundant bits are likely to be the least-significant bits of each byte of the cover-medium


	•Digitally embedding a message in a cover-medium generally involves two basic steps:
		•Identifying the cover-medium’s redundant bits
		•Deciding which of the redundant bits to use to embedding your message by modifying those.
	•In most digital mediums I’ve used steganography with, the redundant bits are generally one or more of the least-significant bits of each data byte or each represented value in the cover-medium.
