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...
In digital rights management (DRM) systems, digital media is often distributed by multiple levels of distributors in a compressed and encrypted format. The distributors in the cha...

We propose a blind watermarking technique to embed multiple watermarks simultaneously. It allows the use of correlated key to embed multiple watermarks. A dual-key system is used ...
This paper presents a new multi-band wavelet watermarking scheme. Compared with conventional watermarking schemes implemented in two-band wavelet domain, by incorporating the prin...
In the present communication, the effects of the eminent JPEG2000 new compression standard on watermarking techniques are investigated. It is shown that the choice of different cod...
