To judge which steganographic algorithm is used for a JPEG image,some possible steganographic operations in DCT domain is investigated and a new steganographic feature space is constructed based on the methodology of micro-templates.

为准确判断一幅JPEG图像使用了何种隐密软件,针对JPEG隐密软件可能采用的DCT域隐密操作,建立了基于微观模板的统计特征空间,并在此基础上提出了一种多类JPEG图像盲隐密分析方法。
