    • [PROBLEMS] To more infallibly prevent leak of information because loss or theft. [MEANS FOR SOLVING PROBLEMS] It is judged whether or not read control information stored in a predetermined read control information storage area of an external storage is proper. If the judgment result shows that it is invalid, virtualized data stored in the external storage is decrypted, and genuine read control information virtualized in the virtualized data is extracted. It is judged whether or not the extracted genuine read control information is proper. If the extracted genuine read control information is proper, the virtualized genuine data in the virtualized data along with the genuine read control information is made usable by decrypting and creating the virtualized data, and improper read control information is stored in the read control information storage area. The proper genuine read control information and genuine data are encrypted to create virtualized data. The virtualized data is stored in a data storage area of the external storage corresponding to the read control information storage area.
    • [问题]为了更可靠地防止信息泄漏,因为丢失或被盗。 解决问题的手段判断存储在外部存储器的预定读取控制信息存储区域中的读取控制信息是否合适。 如果判断结果为无效,则存储在外部存储器中的虚拟化数据被解密,并且提取虚拟化数据中虚拟化的原始读取控制信息。 判断所提取的真实的读取控制信息是否合适。 如果所提取的真实的读取控制信息正确,则虚拟化数据中的虚拟化的真实数据与真实的读取控制信息一起被解密并创建虚拟化数据可用,并且不正确的读取控制信息被存储在读取的控制信息存储区域 。 适当的正确读取控制信息和正版数据被加密以创建虚拟化数据。 虚拟化数据被存储在与读取控制信息存储区域对应的外部存储器的数据存储区域中。
