　　The security of computer always depends on ID-password pair to perform identity authentication for users.while users need to consider the mediation between security and memorability on password creation.at most time they prefer to the latter.thereby cause the leakage of sensitive information In this paper we introduce a novel approach to classify password creation policy according to category attribute.and describe the transform-policy of ID-password pairs across multi websites.at last a scheme is proposed to measure the propagation of sensitive information.mainly focus on individual sensitive information and behavior characteristic of users We collect the data sets from exposed passwords of several websites in China.about tens of millions of password lists The experiment results show that for Chinese users the transform of sensitive information can be evaluated precisely by this means.
