In this paper, a digital watermarking algorithm for copyright protection based on the concept of embed digital watermark and modifying frequency coefficients in discrete wavelet tr...
We proposed a blind watermarking technique to embed the watermark in JPEG compressed domain. Low frequency DCT coefficients are extracted to form an M-dimensional vector. Watermar...
We introduce a new dynamic technique for embedding robust software watermarks into a software program using thread contention. We show the technique to be resilient to many semanti...
This paper2 presents a new approach for the secure and robust copyright protection of digital images. A system for generating digital watermarks and for trading watermarked images ...
This paper proposes a blind audio watermark extraction technique that allows performing watermark decoding while installing data synchronization. The proposed decoding algorithm e...
