Abstract (in Japanese) (See Japanese page) 
(in English) The detection of malicious communications from traffic logs has an aspect of invading the privacy because of monitoring users' whole activities on the network. On the other hand, the use of anonymized data is being permitted due to amendments to the act on the protection of personal information for making good use of big data for society.
In this paper, we created a discriminator for harmless/malicious activities using a publicly available data set of benign/malignant communications. In addition, we devised various methods of partial concealment to avoid personal identification and evaluated the discrimination accuracy by anonymizing features we considered to have a large impact on privacy and inputting them to the discriminator. The results show that the discriminator kept a certain level of discrimination accuracy even when we anonymized features that may invade user's privacy.
