    • An information processor, an information processing method, a program and a storage medium for assuring the prevention of illegal copying even when an application program without having a copy controlling function by itself exists in a system. An information processor comprises a controller for controlling at least one application to which a designated security attribute is assigned, an information storage for storing at least one piece of attribute information indicating a designated attribute and at least one piece of conversion information for converting the designated security attribute, a contents storage for storing a plurality of contents, and a copy prohibition contents discrimination unit for determining whether or not contents requested by an application for reading are copy prohibited contents, wherein the controller converts the designated security attribute based on the conversion information and controls the operation of an application based on the converted attribute information in the case that the copy prohibited contents discrimination unit has determined that the contents in the contents storage requested by the application for reading is copy prohibited contents.
    • 即使在不具有复制控制功能的应用程序的情况下,系统中也存在用于确保防止非法复制的信息处理器,信息处理方法,程序和存储介质。 信息处理器包括:控制器,用于控制指定安全属性的至少一个应用;信息存储器,用于存储指示指定属性的至少一条属性信息;以及至少一条转换信息,用于转换指定的安全性 属性,用于存储多个内容的内容存储器和用于确定由读取应用请求的内容是否为禁止复制内容的复制禁止内容判别单元,其中控制器基于转换信息转换指定的安全属性,以及 在禁止拷贝内容的判断单元已经确定由读取应用请求的内容存储器中的内容是禁止拷贝的内容的情况下,基于转换的属性信息来控制应用的操作。
