Abstract
The authors propose a robust watermark method to cope with the situation when double attacks simultaneously occur. Under a JPEG compression attack and cropping attack whose arbitrary positions to be attacked are assumed. Experiments with a heavy JPEG compression rate of 1/33 show a satisfactory detection ratio of 99.9%.
