Applications of Group Signatures
Kazue Sako
In the talk I will give a brief introduction to what group signature is and
discuss its possible applications. Group signature scheme allows one to sign
anonymously on behalf of a group and was first thought as a tool to enhance
privacy of users. For example, a user can identify himself as a member of
some privileged group and enjoy the membership services anonymously.
However, this conflicts the need of service providers who usually want to
supply personal services to their customers. In the talk we will discuss
alternative scenarios in which the properties of group signatures are more
appreciated by the business companies. This is a on-going work and many
comments are greatly appreciated.
