Evaluation of a fourier watermarking method robustness to cards durability attacks

Abstract

In the context of an industrial application for securing identity cards, image watermarking is used to verify the integrity and authenticity of images printed on plastic cards support. In this area the watermark must survive image modifications related to print-and-scan process and the degradations submitted by ID cards through its lifetime. In this work various card durability attacks were studied (bending, scratches, color fading) as well as some additional other attacks that reflects other possible attacks in the given industrial context. The ID images were watermarked by a new Fourier watermarking method based on print/scan counterattacks (blurring correction and colors restorations) that allows improvement of the robustness of the watermarking method. Results show a noticeable increase of the overall performances of the Fourier watermarking method against durability attacks that is suitable in the context of the industrial application of interest. © 2014 Springer International Publishing.
