摘要： There is provided an anonymous service method of providing local linkability. The anonymous service method providing local linkability according to exemplary embodiments of the invention, an anonymous authentication operation based on a short group signature is performed, for which the concept of a local linkability is introduced to secure linkability within the same service domain. Namely, in the interior of a service provider, a virtual index having a fixed value is calculated for each service user, and in this case, although a plurality of service providers collude with each other, they cannot calculate a virtual index having the same value, whereby the linkability can be secured within the same service domain but not within the interiors of different service domains.
摘要翻译：提供了提供本地可链接性的匿名服务方法。执行根据本发明的示例性实施例的本地可链接性的匿名服务方法，执行基于短组签名的匿名认证操作，为此引入本地可链接性的概念以确保相同服务域内的可链接性。也就是说，在服务提供者的内部，为每个服务用户计算具有固定值的虚拟索引，在这种情况下，尽管多个服务提供者彼此串通，但是它们不能计算具有相同值的虚拟索引从而可以在相同的服务领域内确保可链接性，但不能在不同的服务领域的内部。

摘要： An anonymous authentication-based private information management (PIM) system and method are provided. The PIM method includes receiving an anonymous certificate not including user information from an anonymous certification authority; generating an anonymous document including the anonymous certificate and some of the user information; and providing the anonymous document to a web service provider so as to be authenticated and thus provided with a web service by the web service provider. Thus, only a minimum of user information may be provided to the web service provider. In addition, it is possible to strengthen a user's right to self-determination and control over the exposure and use of his or her personal information by allowing a user to manage his or her own personal information or entrusting the PIM server to manage user information. Moreover, it is possible to protect the privacy of a user by preventing the exposure of user information.
摘要翻译：提供了基于匿名认证的私人信息管理（PIM）系统和方法。 PIM方法包括从匿名认证机构接收不包括用户信息的匿名证书; 生成包括匿名证书和一些用户信息的匿名文档; 以及将该匿名文件提供给web服务提供商，以便被认证，从而由web服务提供商提供web服务。因此，可以仅向Web服务提供商提供最少的用户信息。另外，通过允许用户管理自己的个人信息或委托PIM服务器来管理用户信息，可以加强用户的自我决定权和对自己的个人信息的使用和使用的控制权。此外，可以通过防止用户信息的暴露来保护用户的隐私。
