20100266157 | METHOD FOR EMBEDDING WATERMARK INTO AN IMAGE AND DIGITAL VIDEO RECORDER USING SAID METHOD - The present invention relates to a method for embedding and detecting watermark wherein forgery/alternation of image can be identified and the location of forgery/alternation can be verified by embedding and detecting watermark into a digital image which is shot in real time. Watermark is generated by using a quantized coefficient after frequency transform used in the compression process. By embedding this into an image, image can be compressed simultaneously with embedding watermark. The present invention discloses a method for embedding robust watermark which embeds a random sequence circular shifted from an original pseudo random sequence by the distance d as watermark into an image. The present invention discloses a technology for generating and embedding watermark by using a DCT coefficient quantized during the process for MPEG compressing the image, wherein said watermark can be generated and embedded in a unit of macro blocks or slices. The present invention discloses a technology for generating and embedding watermark by using a wavelet coefficient quantized during the process for wavelet compressing the image. Further, the present invention discloses a digital video recorder recording the image which is shot in real time embedded with watermark in accordance with the above method for embedding watermark. | 10-21-2010 |
