摘要： A hybrid watermark insertion method includes the steps of dividing the digital image into a low frequency region and a high frequency region using an edge map of the digital image; inserting a watermark into the low frequency region of the image by employing a watermarking method using a human visual system (HVS); and inserting the watermark into the high frequency region of the image by employing a quantization index modulation (QIM) method. A hybrid watermark extraction method includes the steps of estimating a reference value used when inserting a watermark, and searching a maximum value of correlation coefficients in an image of the watermark image while changing the estimated reference value within a designated range, to thereby find out the watermark insertion method. Accordingly, the watermark insertion method can be easily identified, thereby enabling the watermark extraction in a more readily manner.
摘要翻译：混合水印插入方法包括以下步骤：使用数字图像的边缘图将数字图像分割成低频区域和高频区域; 通过使用人类视觉系统（HVS）的水印方法将水印插入图像的低频区域; 并通过采用量化索引调制（QIM）方法将水印插入图像的高频区域。混合水印提取方法包括以下步骤：估计在插入水印时使用的参考值，并且在指定范围内改变估计的参考值的同时，在水印图像的图像中搜索相关系数的最大值，从而找出水印插入法。因此，可以容易地识别水印插入方法，从而能够更容易地进行水印提取。

摘要： A system for providing digital contents by using digital fingerprinting includes a contents generation server (140) for generating the digital contents; a clearing house (130) for issuing license of the contents to the client (100) and generating fingerprint information from informatin related to contents purchase information; a fingerprint management server (120) for generating fingerprint code based on the fingerprint information; and a contents distribution server (110) for delivering the contents to the client after inserting the fingerprint code into the contents in watermark form. By generating fingerprint code from information such as copyright holder of the contents, contents provider, etc. and insering the fingerprint code into the contents in watermark form, an illegal distributor can be traced with the fingerprint watermark, although digital contents provided to the client may be illegally copied and re-distributed. Digital content is not encrypted in order for purchaser to replay it on other media devices.
