Abstract
In this paper we will overview the use of data hiding
techniques in digital images. In particular we will describe
how one can use Steganography to hide information in a
digital image. Steganography is related to cryptography and
is the basis for many of the digital watermarking techniques
currently being developed. The interest in data hiding has
risen with the recent activity in digital copyright protection
schemes. One way to protect the ownership of a digital
image is to secretly embed data in the content of the image
identifying the owner. This paper will review recent
developments in data hiding, specifically as it pertains to
copyright protection of digital images.
