This book provides insight into the challenges in providing data
authentication over wireless communication channels. The authors
posit that established standard authentication mechanisms - for
wired devices - are not sufficient to authenticate data, such as
voice, images, and video over wireless channels. The authors
propose new mechanisms based on the so-called soft authentication
algorithms, which tolerate some legitimate modifications in the
data that they protect. The authors explain that the goal of these
algorithms is that they are tolerant to changes in the content but
are still able to identify the forgeries. The authors go on to
describe how an additional advantage of the soft authentication
algorithms is the ability to identify the locations of the
modifications and correct them if possible. The authors show how to
achieve this by protecting the data features with the help of error
correcting codes. The correction methods are typically based on
watermarking, as the authors discuss in the book. Provides a
discussion of data (particularly image) authentication methods in
the presence of noise experienced in wireless communication;
Presents a new class of soft authentication methods, instead of the
standard hard authentication methods, used to tolerate minor
changes in image data; Features authentication methods based on the
usage of authentication tags as well as digital watermarks.
