上のパスワード認証システムのユーザーアカウント登録ページからパスワード構成ポリシーを自動的に取得する技術の実現を研究のゴールとする．本論文は，本研究の初報であり，本技術の必要性や有効性について詳細に論じた．そのうえで本技術の実現のためには，①パスワード構成ポリシーの表示方法の調査，②パスワード構成ポリシー文字列の取得技術の開発が必要となることを示した．その後，①を実施し，パスワード構成ポリシーが掲載されているサイトをクラウドソーシングによって収集し，パスワード構成ポリシーの表示方法について調査した．この結果，クラウドソーシングを通じて計 443 件の認証サイトの収集に成功した．収集したこれらサイトの登録ページを分析した結果，パスワード構成ポリシーの表示方法は 4
