Abstract: An apparatus and method for inserting/extracting a nonblind watermark using features of digital media data are provided. The apparatus and method inserts a watermark adaptively using watermark-related information determined by analyzing the characteristics of digital media data, also extracts features of the digital media data, automatically searches original media data corresponding to the features, and simultaneously and efficiently extracts a watermark using watermark-related information. Therefore, When the watermark is extracted, the original media data can be searched automatically.

Abstract: 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.
