    • The present invention provides a firmware update process capable of realizing both recovery from an interruption of update and saving of a capacity of nonvolatile memory used for backup and storing difference data. Thus, intermediate data is included for always holding a status of firmware in rewriting in addition to the new and old firmware. In a case of updating all blocks configuring the firmware in an arbitrary order, the process successively compares blocks of the intermediate data and new firmware with each other; calculates an address of data for recovery from an interruption of update and a backup capacity required therefor; extracts difference data to be distributed, calculates a capacity thereof and creates an update procedure; and derives a processing order whose total of the backup capacity and the difference data capacity is the minimum (see FIG. 2).

    • In a system to realize prevention of leakage and loss of confidential information by inhibiting writing into a secondary storage device or writing into external storage media, created confidential data is archived by a secure method without being lost if communication is not available and a file server cannot save the information. For this purpose, first, a designated folder is created on a non-volatile storing memory being built in a mobile terminal and created confidential data is saved in the folder. Then, a filter driver controls access to the designated folder to prevent leakage of information by an application in a mobile phone by a malicious user. Further, a function to remove data in the designated folder in the mobile terminal from a mobile terminal management server through a telephone network prevents loss of saved confidential data due to loss of the mobile terminal.
    • 在通过禁止写入二次存储设备或写入外部存储介质来实现防止泄密和丢失机密信息的系统中,通过安全方法来存档所创建的机密数据,而不会丢失如果通信不可用并且文件服务器不能 保存信息。 为此,首先,在内置在移动终端中的非易失性存储存储器上创建指定的文件夹,并将创建的机密数据保存在文件夹中。 然后,过滤器驱动器控制对指定文件夹的访问,以防止恶意用户在移动电话中由应用程序泄露信息。 此外,通过电话网络从移动终端管理服务器移除移动终端中的指定文件夹中的数据的功能防止由于移动终端的丢失而导致的保存的机密数据的丢失。

    • The present invention provides a firmware update technique in which a work area is small, a work time is short, update can be resumed even if power-down occurs, and even a file system which does not support writing is supported. To provide the firmware updating technique, an update creating and distributing server divides old and new version firmware images, extracts a difference between the new and old divided firmware images, creates an updated package, and delivers the updated package to an embedded device. On the other hand, the embedded device applies the updated package to the old version divided firmware image (an existing firmware message currently in use).
    • 本发明提供一种固件更新技术,其中工作区域小,工作时间短,即使发生掉电也可以恢复更新,甚至支持不支持写入的文件系统。 为了提供固件更新技术,更新创建和分发服务器分割旧版本和新版本固件映像,提取新的和旧的分割固件映像之间的差异,创建更新的包,并将更新的包传送到嵌入式设备。 另一方面,嵌入式设备将更新的包应用于旧版本的分割固件映像(当前正在使用的现有固件消息)。

    • Each of a dynamic image delivering server A 132 and a dynamic image delivering server B 133 delivers a plurality of contents list data and a dynamic image designated by each contents list data. A transcoding server 131 acquires prescribed contents list data from the dynamic image delivering server A 132 and/or the dynamic image delivering server B 133, and stores them in a storage device. Then, the transcoding server 131 acquires the dynamic image designated by the acquired contents list data from the dynamic image delivering server A 132 and/or the dynamic image delivering server B 133, converts the acquired dynamic image to a format of the dynamic image regenerable on a player 111, and stores the converted dynamic image in the storage device. Upon request from the player 111, the transcoding server 131 retrieves a contents list data and/or a dynamic image from the storage device, and transmits them to the player 111.
