It is nowadays more probable that a print media is captured and shared with a mobile phone
than with a scanner. The reasons for photographing the print range from intention of copying …

Thus far the research of print-cam robust watermarking methods has focused on finding new
methods for embedding and extracting the watermark. However, the capturing process itself …

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

The onboarding of IoT devices by authorized users constitutes both a challenge and a
necessity in a world, where the number of IoT devices and the tampering attacks against …

Given the penetration of mobile devices equipped with cameras, there has been increasing
interest in enabling user interaction via visual codes. Simple examples like QR Codes …

Due to the rapid advancement in processing power and camera quality of mobile devices,
research on the display-to-camera (D2C) communication channel has recently received …

In this paper, we propose a digital image watermarking method for camera-captured images.
In our proposed method, an image component of all image pixels is used for embedding an …

Perspective deformation is one of the major issues in print-cam attacks for image
watermarking. In this paper we adapt to print-cam process a Fourier watermarking method …

Image watermarking often involves the use of handheld devices under non-structured
conditions for authentication purposes, particularly in the print-cam process where …

In this paper, the possibility to apply conventional watermarking methods in a print-cam
process is discussed. In the print-cam process, the watermark is read from a printed image …
