With the development of Internet technology, digital products can be found everywhere. To realize the inspection of unauthorized modification, this paper puts forward a trade scheme based on the asymmetric double digital watermarking technology. In the scheme, asymmetric robust watermarks contained the publisher and user information are embedded to protect the copyright and resist the malicious attack to carrier, meanwhile a fragile watermark containing identification information of product is embedded to detect the tamper with products. At last, the simulation and analysis of this scheme on Internet shops shows that our system can realize the detection of illegally tampering with product, copyright protection and sources tracking of illegal product.
