Abstract
Digital watermarking of multimedia content
has become a very active research area over
the last several years. A general framework
for watermark embedding and detection/decoding
is presented here along with a review of some of
the algorithms for different media types described in the
literature. We highlight some of the differences based on
application such as copyright protection, authentication,
tamper detection, and data hiding as well as differences in
technology and system requirements for different media
types such as digital images, video, audio and text.
