本文根据小波变换原理和LSB 技术提出了一种提高鲁棒性的灰度图像水印算法，使水印系统抗攻击能力大大增强。水印的提取并不需要原始载体图像的参与，实现了真正意义
上的盲水印检测。

Abstract: This article according to the wavelet transformation principle and the LSB technology proposed one kind enhanced the robust gradation picture watermark
algorithm, caused the watermark system anti- attack capability big enhancement. The watermark withdraws certainly does not need the primitive carrier picture the
participation, has realized in the true significance blind watermark examination.
Key words: Digital watermark; Wavelet transformation; LSB;Information hideaway
