Abstract
This paper presents the challenges presented by geometric transformation attacks to
\Vatermark synchronization. Geometric distortion attacks can prevent proper detection
of the watermrk by destroying the synchronization between the watermark and the
watermark detector. This paper proposes two approahes to deal with tllis problem.
The irst approach remm·es strict spatial synchronization requirements of the
watermark. while the second approach enables watermark re-synchronization ater a
geometric attack.
wors: Digital watermarking. multimedia security. geometric trsformation.
