摘　　要：设计并实现了一种基于水印的数字图像审计网关,不但保证了图像的实时审计,还保证了图像的版权的归属认证和直接获取数字图像访问者的信息。基于DWT、DCT的数字水印算法,实现对图像版权归属问题的认证;并对接统一身份认证系统,有效的获取访问者的身份信息,构建出包含有访问者、访问行为、图像版权归属认证的完整审计链。为了验证设计方案的有效性,构建了图像云平台实验环境。网关数据包的捕获能力较高,实现了数字图像版权的归属认证与审计,并且满足了图像云平台中图像审计的性能要求。In this paper,the digital image audit gateway based on watermark was designed and implemented,it not only ensures the real time image audit,but also ensures the image on the ownership of the copyright certification and direct accesses to visitors to the digital image information. Digital watermarking algorithm based on DWT and DCT,it could have achieved the digital image copyright ownership of the certification; Docking the uniform authentication system,the gateway could have acquired the identity information of visitors it constructed the complete audit chain which included the visitor,the visit behavior,the image copyright attribution authentication. In order to verify the validity of the design,we build the image cloud platform experiment environment. It shows that the capacity for capturing packets of the gateway is very high,achieves a cloud platform digital image copyright attribution audit,and meets the cloud platform digital image audit performance requirements.
