Recent Patents and Publications on Digital Watermarking

Author(s): Mahmood Al-khassaweneh.


Digital watermarking has become a hot research topic in recent years. The main aim of digital watermarking is to prevent unauthorized reproduction of digital data and to protect copyrights. Most of the research on digital watermarking deal with invisible and robust watermark. The techniques and algorithms proposed in literature for watermarking can be grouped into three classes: time domain, frequency domain and time-frequency domain. In this paper, we review some recent research and patents on digital watermarking in the three different domains published within the last three years with main focus on invisible robust watermarking.

Keywords: Digital watermarking, patents, steganography, encoding, decoding, Time-Frequency Domain Techniques, Spatial (Time) Domain Techniques, Transform (Frequency) Domain Techniques, Fingerprinting, Broadcast Monitoring, Perceptual transparency
