摘要：

This paper presents a robust Discrete Wavelet Transform (DWT) based color image watermarking technique using YCbCr color model. Watermark text data is transformed into QR code for enhanced security and a varying length text can be watermarked in an efficient manner. The proposed method uses diagonal components from DWT of the cover and watermark image. A high retrieval rate of watermarks is obtained with an appropriate embedding strength. It has high resistance to most watermarking attacks and retrieves the exact watermark information even from low quality watermarked images.
