SMC '06. IEEE International Conference on (Volume:4 ), pp.3170-3175This paper presents a novel digital watermarking technique based on support vector machines (SVMs) and tolerable position map (TPM). The purpose of SVMs is two folds in this study. One is using SVM to identify tolerable positions for watermark embedding on the host image, and the other is using SVM to embed and extract watermarks. By simulating common image attacks on the host image, pixels which are invincible or vulnerable are identified and used for positive or negative samples for training an SVM. Apply this SVM can create a TPM for the host image. To embed and extract watermarks, we use a known binary sequence to train an SVM such that this SVM can be applied for embedding and extractin
