Abstract

本案是有关于一种资料媒体，其具有一非挥发电子内存(2)，系用以保持大量的资料；以及一微控制器(3)，系适合用来执行一加密操作，仅有藉由该微控制器才可允许存取该内存(2)。此具有创造性的资料媒体其特征在于在该资料被储存在该内存(2)之前，一使用者系以使用该微控制器(3)的一资料来源而被认证。

Description

资料媒体
本案是有关于一种具有一种非挥发电子内存的资料媒体，用以保持大量的资料，与一种微控制器，适合用来执行密码操作，仅藉由该微控制器才可允许存取该内存。
此类的资料媒体之使用是为了能够储存大量的的资料，该资料媒体也适合做为一种可置换的媒体。藉由一微控制器来保护资料的存取是预防资料被未被授权的第三者存取而来保护资料。
在一比较新的应用中，此类可置换的资料媒体系被用来储存，例如，音乐档案或者是从网际网络下载的电子书。在一种可能的应用实例中，一种标准的个人计算机被用来做为一个加载站(loadingstation)，其可获得档案并将档案储存在资料媒体。储存的数据然后可被重放在一可携带的重放单元，例如，在一行动MP3播放机。
在其它的应用中，此类的资料媒体系当作一种可置换的软盘或是可置换的硬盘。在此实例中，需要预防被未被授权的第三者存取之灵敏度高的资料常常被储存。为此，档案在储存至资料媒体之前可被加密并且接着可被以加密的格式储存在该资料媒体中。然而，其意为需要花费较多的努力，以至于在许多实例中省掉此加密的动作。
所述及的可能性其可预防资料可能被未被授权的第三者读取。然而，在许多实例中，资料被传送至的人对资料来源而言也不是无意义，例如，因为系牵涉受到成本管制的资料。此等问题并无法由以上所提及的设备来解决。
因而本案其中一个目的系为详细说明适合用来保持大量的资料的一种资料媒体，其可使具有高等级安全性的储存资料与控制资料输出两者成为可能。
此目的可藉由在前言中所述形式特征的一种资料媒体而达成，在资料被储存至内存之前，使用者以利用该微控制器的资料来源而被认证。
此资料媒体具有创造性的设计因而可确保资料都可用加密的格式被储存在内存中。同时，微控制器系被用来认证该使用者，当加密储存容许资料因一使用者而被保护时，该使用者的认证使该资料来源得以确认资料仅被输出至一特定的使用者。
在一个较佳实施例中，内存系大于1Mb且是以一芯片卡的形式。
本案将由以下示范性实施例来做较详细之说明，而图标系描述一具有创造性的资料媒体，其系安排从网际网络来下载资料。
一资料媒体1，系具有一非挥发的大容量内存2，其储存容量一般系大于1Mb。因为该内存芯片其可能利用不同的技术，例如，Flash、单次写入(OTP)或者同类的技术。以一种芯片卡(chip card)形式的资料媒体，并具有可应用标准加密的一加密控制器3，其较佳是RSA或者是椭圆形曲线。该资料媒体系被连接至一加载工作站4，此连接可经由电接触区域或是经由一天线以非接触的方式来完成。所提供的加载工作站4可以是特殊的单元或者是一般的个人计算机(PC)以提供一适合的接口来与该资料媒体1进行通讯。此加载工作站4接着可被连接至网际网络5，假使加载工作站4为可与网际网络建立无线通讯的一行动无线电，是有利的，而创造性的资料媒体因而可被特别灵活的使用。
微控制器3可灵活地提供安全性量测，因此微控制器在网际网络中做为一服务提供者来进行客户的识别，以及付款程序，例如，一EC卡或者是现金卡。然后，内存2可保持该下载的资料，与被以加密形式储存在该内存中的资料。
在一修饰的应用中，加密资料系被该微控制器3在下载时进行加密，因而其可被使用者存取。在此情形中，钥匙(key)本身与凭证此两者皆被储存在资料媒体中以做为存取该资料最适当的保护。
为了产生此安全性途径，可能使用所有来自先前技术领域中已知的量测，因为其皆可被微控制器3所使用。加密技术将来的发展也因此被考虑。
此类卡片的安全性胜过CD或者是其它的DVD，并且容许在电子商务(e-commerce)领域中的数字权利管理(Digital Rights Management，DRM)。
