A blind watermarking technique for multiple watermarks
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 ...

Multiple Domain Watermarking for Print-Scan and JPEG Resilient Data Hiding
In this paper, we propose a print-scan resilient watermarking method which takes advantage of multiple watermarking. The method presented here consists of three separate watermarks...

A blind cdma image watermarking scheme in wavelet domain
The paper proposes a blind spread spectrum watermarking scheme where watermark information is embedded redundantly in the multilevel wavelet coefficients of the cover image. It ha...

A blind watermarking technique in JPEG compressed domain
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...

Quantization Based Blind Watermarking Algorithm Using DWT
- In this paper a Discrete Wavelet Transform based blind watermarking algorithm is proposed for embedding a grayscale watermark into a grayscale image. A new approach of choosing t...
