Research Partners

Updated the information about our research partners. Having industry partners is really great to us as we get invaluable opportunities to find/identify interesting research topics that do have impact to the real world. Their financial supports are also greatly appreciated. Hope we can enhance the circle of research collaboration.

取材協力(日経新聞)

日経新聞の記事「偽サイト対策、海外に学べ 五輪チケット販売で懸念 強制閉鎖やドメイン活用」に取材協力しました。

早稲田大学の森達哉教授らの調査によると、ネット上の住所にあたるドメインに「tokyo」や「2020」を含み、五輪公式サイトと誤認させるドメインが約950もあることが判明。一部は悪用されていた。

森氏は「金銭のやりとりが生じるタイミングで不正サイトが急増しかねない」と懸念する。三井住友銀行の略称「smbc」に似せて誤認を誘うドメインも増えている。

記事中のデータは、下記で公開している通りです。その後、5月から大きな変化は観測していませんが、来年の開催に向けて今後も注視していきたいと思います。
