| Summary: | The
algorithm
of
formation,
embedding
and
extracting
of
digital
watermarks
using
discrete
chaotic
maps
is
considered.
The
key
feature
of
the
developed
algorithm
is
the
formation
of
the
watermark
using
the
discrete
chaotic
map
and
the
restoration
of
this
watermark
after
the
image
transmission
via
the
communication
channel.
This
is
possible
through
the
use
of
the
developed
method
that
searches
for
initial
values
of
discrete
chaotic
map
variables
used
in
the
formation
of
the
watermark.
The
algorithm
testing
re
sults
are
given.
It
is
established
that
the
proposed
algorithm
is
able
to
identify
the
modified
image
areas.
The
algorithm
is
resistant
to
image
conversion
in
JPEG
format
and
to
distortion
up
to
14
% of the image pixel values due to the presence of noise. Thus, the proposed algorithm can be used to solve real problems of the defense of digital images transmitted by communication channels. |
