水印系统必然要在算法的鲁棒性、水印的嵌入信息量以及水印嵌入之后的不可觉察性之间达到一个平衡。这涉及鲁棒性算法的原理性设计、水印的构造模型、水印能量和容量的理论估计、-Watermarking system must be robust in the algorithm, the embedded watermark information, as well as after the watermark embedding is not aware of to achieve a balance

LSB 方式信息隐藏算法鲁棒性较差，为加大水印攻击难度，可采用一段伪随机序列来控制水印嵌入位置。-LSB mode information hiding algorithm less robust, in order to increase the difficulty of watermarking attack, a pseudo-random sequence can be used to control the watermark embedding locations.
