Security checking can be improved by watermarking identity (ID) images printed on smart
cards plastic supports. The major challenge is resistance to attacks: printing the images on …

Watermarking for identity images printed on a plastic card support is still challenging. In this
application, the scheme must be robust against a combination of geometric and signal …

In recent past years, Fourier based watermarking techniques have been developed to deal
with the print-and-scan attack. In this work, print-and-scan counterattacks for Fourier …

Digital image watermarking is an active research field since it provides protection, security,
and authenticity of data. This paper presents development and implementation of a blind …

This paper investigates a robust method to watermark and decode images such as identity
pictures printed on plastic card supports that have a special interest in industrial areas …

Fourier watermarking is often chosen to watermark images that have to be printedand
scanned on a physical support, during which the so-called print-scan attack occurs …

A major challenge for E-commerce and content-based businesses is the possibility of
altering identity documents or other digital data. This paper shows a watermark-based …

In this paper, we evaluate the degradation of an image due to the implementation of a
watermark in the frequency domain of the image. As a result, a watermarking method, which …

Image watermarking with both insensible detection and high robustness capabilities is still a
challenging problem. Even if some of the watermarking areas involve huge financial …

Smartphone watermarking has many potential applications but also many challenging
issues such as being able to withstand print-cam attacks. These include perspective …
