Device ID

The Device ID is a device identifier string that RiskMinder generates on the end user’s device to identify and track the device that the end user uses for logging into your online application and performing transactions. The Device ID information is in encrypted format.

The following are the options for storing the Device ID on the end user's device. The plugin store is the most persistent storage option.

• AuthMinder Plugin store: The AuthMinder plugin store is automatically created on the end user’s device when the CA ArcotID OTP Client is installed on the end user’s device. Among the storage options listed in this section, the plugin store is the most persistent storage option. A Device ID that is placed in the plugin store cannot be deleted by common end user actions such as clearing browser cache and deleting browser cookies. The plugin store is supported from CA RiskMinder Client release 2.1 onward.
• Local storage provided in HTML5
• UserData store: This store is available only in Microsoft Internet Explorer
• Cookie store: Typically, on Microsoft Windows, the Device ID is stored in one of the following folders:
  • Internet Explorer on Microsoft Windows 7 or 2008:

    C:\Documents and Settings\<user_profile>\Application Data\Microsoft\Windows\Cookies\
    

  • Internet Explorer on Microsoft Windows 2003 or XP:

    C:\Documents and Settings\<user_profile>\Cookies\
    

  • Mozilla Firefox:

    C:\Documents and Settings\<user_profile>\Application Data\Mozilla\Firefox\Profiles\<random_dirname>\cookies.sqlite
    

  • Safari:

    C:\Documents and Settings\<user_name>\Application Data\Apple Computer\Safari\cookies.plist
    
    

Important! From CA RiskMinder Client version 2.0 onward, the Device ID is not stored as a Flash cookie. If you have existing Flash cookies from an earlier release, then these cookies are automatically migrated to one of the stores listed earlier in this section.
