This paper proposed an image robust spatial domain watermark algorithm based on general Arnold mapping and neural network model.Embedding position of the original binary watermark was generated by Arnold map in random,and then trained a neural network to memorize the relationship among pixels of each sub-block image.Moreover,used magnific information technology,and all these enhanced watermark embedded.Experimental results demonstrate that this algorithm has robustness against cutting attack,LSB attack,peppersault,and so on.
