摘　　要：为解决图像隐写技术评价方法研究滞后于信息隐藏技术发展的问题,提出基于图像的隐写算法性能评价体系,包括指标体系,测评体系和综合测评体系。在分析隐写算法特性的基础上,提出隐写算法指标体系;从测评框架,测评策略,测评方法和测评工程建立测评体系;采用二级模糊综合评估模型对图像隐写算法的性能进行综合评价。实验结果表明,利用该评价体系可以对现有的隐写算法进行有效评价。To solve the problem that research on evaluation for steganography based on image lags back the development of information hiding, the evaluation system for steganography based on image which includes index system, testing system and comprehensive testing system is proposed. Firstly, steganography evaluation index system is proposed considering the characteristics of steganography. Then steganography evaluation testing system composed of testing framework, testing policy, testing methods and testing project is proposed. Finally, two-level fuzzy comprehensive evaluation method is selected to measure the performance of steganography based on image. The common steganography tools are evaluated using the system, whose feasibility is proved in experiments.
