    • Provided is a data management device for managing data recorded onto a readable and writable recording medium by an application that is verified based on a digital certificate. The recording medium has a plurality of areas and access to each area is restricted to a different application. The data management device includes an application authentication module, a mapping module, and a local storage display module. The application authentication module verifies that an application is an authentic application based on a digital certificate attached to the application. The mapping module associates, if the application is verified, an area accessible by the application with a subject name described in the digital certificate used for the verification. The local storage display module displays information regarding the area accessible by the application, with the use of the subject name associated with the area.
    • 提供了一种数据管理装置,用于通过基于数字证书进行验证的应用来管理记录在可读写的记录介质上的数据。 记录介质具有多个区域,并且对每个区域的访问被限制到不同的应用。 数据管理装置包括应用认证模块,映射模块和本地存储显示模块。 应用认证模块基于附加到应用的数字证书来验证应用是真实的应用。 如果应用程序被验证,则映射模块将由用于验证的数字证书中描述的具有主题名称的应用程序可访问的区域相关联。 本地存储显示模块使用与该区域相关联的主题名称显示关于应用程序可访问的区域的信息。
