          <datacite:description descriptionType="Other">本稿では，ユーザが匿名のまま権利を主張しこれを行使でき，またサービスを提供する側は匿名者であってもその不正行為の取締りが可能な，新たな認証方式を提案する．多くの場合，認証の目的は，利用者が誰であるかを特定することではなく，利用者がその権利を持つかどうかを確認することである．本方式は，このような認証場面に適用することを想定している．本方式では，裁判官と名付けた1つの特殊機関を設置した世界モデルにおいて，ブラインド署名や確率的暗号など種々の暗号技術を応用して作成した電子証明書を利用する．これによって，個人情報の保護を実現しつつ，不正者への容易な対応を可能とした認証方式を実現している．</datacite:description>
          <datacite:description descriptionType="Other">Our system enables an anonymous person to prove his rights and a verifierwho provides services or resources for his users to trace and catch illegal anonymous users.In many cases, the purpose of authentication is not to identify a user,but to verify the user's rights.Our system is suitable for these situations.In our system, no privacy information is acquired by a verifier,unless the user performs an illegal action.We define a model that includes a `Judge' as a special authority,and make and use special electronic certificates by using some cryptographic techniques(e.g., a blind signature and probabilistic cryptosystem) in that model.</datacite:description>
