Virtual secure digital card

摘要

A system (and a method) are disclosed for generating a virtual secure digital (SD) card. One embodiment detects an SD card and reads a media key block and media identification for the SD card. The system stores the media key block and the media identification. The system creates a file system for secure data on a storage device for storage of secure data corresponding to a secure data area of the SD card and creates a file system for user data on the storage device for storage of user data corresponding to a user data area of the SD card. In addition, the system uses the virtual secure digital (SD) card. The system determines if the virtual SD card is provisioned and provisions it if not. The system accesses the data stored in the secure area of the provisioned virtual SD card. The system extracts the data from the secured area of the provisioned virtual SD card.
