- W2374105553 abstract "The relation between the digital watermarking and spread spectrum communication is analyzed at first ,then a blind watermarking method based on spread spectrum technique is put forward. With this method, each watermark bit is embedded using two DCT coefficient blocks of host image, The blocks are so quantized that they exhibit a large enough statistical difference which will later be used for watermark extraction. Experiment results show that the watermarking is invisible and robust and that the checking probability of false positive error is very low in this proposed scheme." @default.
