Computing the Probability of False Watermark Detection
[chapter]
2000
Lecture Notes in Computer Science
Preserved Fulltext
Several methods of watermark detection involve computing a v ector from some input media, computing the normalized correlation between that vector and a prede ned watermark vector, and comparing the result ...
This expression depends only on the detection threshold and the dimensionality of the watermark vector. ...

The maximal number of detections that can be performed in a geometrical search is bounded by the maximum false positive detection probability required by the watermark application. ...
Furthermore, the image and key dependency of the tested watermark detector increases the random-imagerandom-key false positive detection probability, compared to the Bernoulli experiment that was used ...
From this computational point of view, the exhaustive geometrical search was chosen to contain 150,000 watermark detections. ...

In this paper we analyze the false positive probability of the correlation ratio detection measure under a reasonable assumption about the distribution of unwatermarked works. ...
This false positive probability is well understood for detectors that use a normalized correlation detection measure. ...

Aiming at the problems of high false positive rate and poor robustness in group verification of existing reversible watermarking schemes in WSNs, this paper proposes a scheme using reversible watermarking ...
Analysis and experimental results show that compared with the previously known schemes, the proposed scheme can avoid false positive rate, reduce computation cost, and own stronger grouping robustness. ...
More forward the position is, the shorter the detection time is, the lower the probability of fail of detection is. ...
