Abstract:
A secure flash memory card or flash drive protects user content from unauthorized duplication. However, even the protected user content can be moved from one flash card or drive to another by its rightful owner or licensee. Additionally, secure firmware applications that may be added to the flash card over time in order to add additional functionality to the card may also be moved, although many of them are device specific and also designed to only operate on one particular piece of hardware.
