Description
Summary:Printed documents protection problem against leakage is still one of the relevant. Existing security tools allow us to protect electronic text documents, however are ineffective in protecting their printed versions. This research presents the marking approach for text electronic documents invariant to the print-and-scan transformation. During marker embedding source text line spacing values are changing to the specified values within perceptual invisibility. The watermark extraction is carried out from the images containing text and based on normal Radon transform and Gaussian mixture model. This marking approach is robust to various image transformations and distortions. The accuracy of embedded information extraction was more than 0.98 for 200 DPI images and line spacing value change about 490 micrometers.
