    摘要: Disclosed are a forensic marking method and a forensic marking system capable of inserting in real-time a forensic mark for user information in digital contents provided online. The forensic marking method of the digital content according to an exemplary embodiment of the present disclosure includes generating a first content created by inserting a first forensic mark in an original content and a second content created by inserting a second forensic mark in the original content by a content server; transmitting the first and second contents to a client terminal by the content server; and combining fragments of the first and second contents in a combination order corresponding to user information to generate a third content by the client terminal

    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.
