摘      要：An improved Image watermark algorithm(IIWA) is given in this paper, the with flow chart and the work principle of this algorithm are introduced in detail Although the normal watermarking technique brings up a new way of securing data transactions through the Internet, its robustness and integrity are vulnerable during the net transmission and image processing Using network signature technique, varied coding methods and other unique technique, IIWA improved the general watermark algorithm in the robustness and integrity in other words, IIWA greatly enhanced the transmission security and can be applied to information protection in the Internet
