To use results of watermark detection, a detection error probability is
required to be low enough.
We have derived a property satisfied commonly by correlation based
watermarking schemes,
and have proposed a method to ensure the false positive error
probability for correlation based watermarking scheme.
The watermark detection is regarded as a hypothesis testing of the
hypothesis on the derived property in the method.
In general hypothesis testing,
the false negative error probability can be reduced
by employing a large sample size
while ensuring the false positive error probability.
However, in the method, a large sample size causes
increase of the false positive error probability, that is,
the false positive error probability is not ensured.
In this paper, we solve this problem and
propose a method to ensure the false positive error probability
for correlation based watermarking
which reduces the false negative error probability. |
