  Abstract

Digital watermarking has similar concepts with channel coding technique for transferring data with minimizing error in noise environment, since it should be robust to various kinds of data manipulation for protecting copyrights of multimedia data. This paper proposes a digital watermarking technique which is robust to various kinds of data manipulation. Intellectual property rights information is encoded using a convolutional code, and block-interleaving technique is applied to prevent successive loss of encoded data. Encoded intellectual property rights information is embedded using spread spectrum technique which is robust to data manipulation. In order to reconstruct intellectual property rights information, watermark signal is detected by covariance between watermarked image and pseudo random noise sequence which is used to embed watermark. Embedded intellectual property rights information is obtained by de-interleaving and decoding previously detected watermark signal. Experimental results show that block interleaving watermarking technique can detect embedded intellectual property right information more correctly against to attacks like Gaussian noise addition, filtering, and JPEG compression than general spread spectrum technique in the same PSNR.
