Digital watermarking is a technology for embedding digital information in digital content (audio, images, video…). Recently, the watermarking is introduced as a tool to improve the security of identity documents. In this paper, we propose a watermarking algorithm operating in discrete wavelet transform (DWT) using mixed scales representation and(More)
will organize the next ICISP event. ICISP aims to provide researchers and practitioners from academia and industry with a forum on the last developments in image and signal processing, multimedia and computer graphics. The conference will also provide a unique opportunity for sharing experiences from different backgrounds with the common interest in(More)
The print-scan operation is still challenging in the watermarking community, some watermarking techniques were proposed in the literature to deal with this operation. These watermarking techniques are still very sensitive to degradations produced by the print-scan process. This paper investigates a watermarking technique in the Fourier domain that is robust(More)
