    Abstract: 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.

    Abstract: 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.

    Abstract translation: 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。

    Abstract: The present invention relates to a content protection apparatus and method using binding of additional information to an encryption key. The content protection apparatus includes an encryption unit for creating an encryption key required to encrypt data requested by a user terminal and then generating encrypted data in which the data is encrypted. An additional information management unit manages additional information including authority information about the encrypted data. A White-Box Cryptography (WBC) processing unit generates a WBC table required to bind the encryption key corresponding to the encrypted data to the additional information. A bound data generation unit generates bound data in which the encrypted key is bound to the additional information, using a cipher included in the WBC table.
