An efficient print-scanning resilient data hiding scheme based on a novel LPM
Print-scan resilient data hiding has not been extensively researched. This paper presents an efficient multi-bit blind watermarking scheme based on a novel Fourier log-polar mapping (LPM). The watermark resynchronization after print-scanning is efficiently solved by an embedded tracking pattern which cannot be removed by template removing attacks and is not detectable for a malicious part. Experimental results show that the proposed watermarking scheme has excellent robustness to print-scanning, cropping, geometric distortion and JPEG compression etc. The obtained success ratios of extraction 60 bits message without error from the combination attack of JPEG compressed with quality factor of 50-100 and then print- scanning were at least 95%.
