摘要：
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 the network digital signature technique and vaned coding methods, an improved image watermark algorithm (IIWA) based on the transmission security is introduced in this paper. This algorithm improved the general watermark algorithm in the robustness and integrity and can be applied to the information protection field in the Internet.
