Windows CardSpace(WCS)

Windows Cardspace是新一代的统一身份验证解决方案。它与微软之前的Passport是有相似之处，但也有不同之处的。这篇博客简要地对其进行介绍

1. 运行机制

• Vista和Win 7自动具有该功能。XP需要安装SP3才有。
• 隔离的进程（Session隔离）
• 背景其实是一个图片，灰色的，不会有任何变化（包括时钟），用一个图片只是为了减少用户的疑虑。
• infocard.exe(wcs引擎）,icardagt.exe(代理程序）——它们之间通讯

2. 标识提供着(identity provider)

• 负责验证身份信息的一方

3. 个人卡和托管卡

• 个人卡其实是存储在本地的，它的信息是有限的（是规定的那么几项），个人卡其实是自己充当验证提供者。
• <Drive>:\Users\<username>\AppData\Local\Microsoft\CardSpace\CardSpace.db on Windows Vista.
  <Drive>:\Documents and Settings\<username>\Local Settings\Application Data\Microsoft\
  CardSpace\CardSpace.db on Windows XP and Windows Server 2003
• 托管卡则是存在在特定的第三方提供商处的。它的信息不存在本地
• 本质上，它们是一样的。只是信息提供方不一样。

4. 个人卡的信息
