摘要
从数字水印技术本身的特点、一般模型和典型算法出发,结合包装、印刷的防伪要求,提出了一种基于小波变换的数字水印技术实施框架,着重分析了难点所在,并对其应用前景做出展望。
The feature of digital watermark,general models and arithmetic were introduced. A digital watermark application frame based on wavelet transform was discussed, which is suitable for the demand of packaging and printing forgeproof. The key problems and prospects of digital watermark's application were put forward.
