Configuring Device ID and DeviceDNA

RiskMinder uses Device ID and DeviceDNA to register and identify the device that is used by a user during transactions. The Device ID is stored on the end user's device. 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.

• Plugin store: The plugin store is a permanent store on the end user’s device. 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 that is 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 release 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 that are listed earlier in this section.
