    • 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.
    • 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。

    • The present invention relates to a plate type speaker adapted to radiate sound by transforming horizontal vibration for vibrating a side of a diaphragm into vertical vibration of the diaphragm. The plate type speaker of the present invention comprises a plate-shaped diaphragm for receiving horizontal vibration to generate vertical vibration; a base frame having a fixing portion to which one end of the diaphragm is coupled; a voice coil plate that has one end connected to the other end of the diaphragm, is mounted on the base frame to horizontally vibrate and has a voice coil wound on either or both of surfaces thereof, and a magnetic body that has opposite polarities at positions spaced apart by predetermined distances from top and bottom surfaces of the voice coil plate and is coupled to the base frame. According to the plate type speaker of the present invention, it is possible to manufacture a plate type speaker with a thickness reduced through transformation of vibration at a side of a diaphragm, which is caused by horizontal vibration of a voice coil plate, into vertical vibration of the diaphragm. Accordingly, the plate type speaker of the present invention can be easily applied to small appliances requiring an audio system, and it is also possible to manufacture plate type speakers in various forms with a plurality of diaphragms depending on the structure of a base frame.
    • 本发明涉及一种板式扬声器,其适用于通过将水平振动转换成振动膜片的一侧振动的垂直振动来辐射声音。 本发明的板式扬声器包括用于接收水平振动以产生垂直振动的板状隔膜; 底架,其具有固定部分,所述隔膜的一端连接到所述固定部分; 具有连接到隔膜的另一端的一端的音圈板被安装在基架上以水平地振动并且在其一个或两个表面上缠绕有音圈,并且在位置处具有相反极性的磁体 与音圈板的顶表面和底表面间隔开预定距离并且连接到基架。 根据本发明的板式扬声器,可以制造通过由音圈板的水平振动引起的振动膜一侧的振动变形而减小的板式扬声器成垂直振动 的隔膜。 因此,本发明的板式扬声器可以容易地应用于需要音频系统的小型电器,并且还可以根据基架的结构,利用多个隔膜制造各种形式的板式扬声器。
