Abstract: The information hiding technology is a new developing information security
technology in recent years.This paper first introduces the fundamental conception of the
information hiding technology comparing with encryption,then describes a general model
of information hiding system and its performance.Furthermore,analyzes the difference
between steganography and digital watermark, meantime discusses several algorithms.
Finally, discusses the application in secret communications and copyright protecting.
