摘要

PPROBLEM TO BE SOLVED: To provide an information processor, the data updating system of the information processor and the data updating method of the information processor for preventing the illegal installation of predetermined data for update of map data. PSOLUTION: A hard disk device 10 is preliminarily stored with an authentication code obtained by cipher-transforming map data and the equipment specific code of a car navigation device 1 in a first system. At the time of updating the map data, a user purchases a DVD-ROM 3 for map update in a store, and acquires an authentication code prepared by cipher-transforming the equipment specific code notified through the store in first and second systems by an authentication institute and a new equipment specific code. When a DVD-ROM 3 is set in a DVD drive part 13, and the authentication code is input by instructing map update by an input part 14, a control part 15 installs the map data from the DVD-ROM 3 to a hard disk device 10 when the input authentication code is matched with the authentication code of the hard disk device 10, and transforms the authentication code, and prepares the same new authentication code as that obtained by cipher-transforming the new equipment specific code in the first system, and rewrites the authentication code of the hard disk device 10.

要解决的问题：为了提供一种信息处理器，该信息处理器的数据更新系统和该信息处理器的数据更新方法，用于防止非法安装用于更新地图数据的预定数据。

解决方案：硬盘设备10预先存储有通过对第一系统中的地图数据和汽车导航设备1的设备专用代码进行密码转换而获得的认证代码。在更新地图数据时，用户在商店中购买用于地图更新的DVD-ROM 3，并获取通过对第一和第二系统中通过商店通知的设备专用代码进行密码转换而对认证进行准备的认证代码。制定新的设备规范。当将DVD-ROM 3放置在DVD驱动器部分13中时，通过指示输入部分14更新地图来输入认证码，控制部分15将地图数据从DVD-ROM 3安装到硬盘设备上。当输入的认证码与硬盘设备10的认证码匹配时，如图10所示，对认证码进行转换，并准备与通过在第一系统中对新设备专用码进行密码转换而获得的新认证码相同的新认证码;以及重写硬盘设备10的身份验证代码。
