Patent ID: 8276188

Claim:
A system for managing storage devices, comprising: a storage device, comprising: a storage area; a microprocessor; and a microcontroller receiving an access request, determining whether the access request conforms to a specific protocol or whether the access request is requesting to activate the microprocessor, and transmitting the access request to the microprocessor when the access request conforms to the specific protocol or when the access request is requesting to activate the microprocessor, wherein the microprocessor executes a Card Operating System (COS), and directly manages the storage area without communicating through the microcontroller by performing the access request based on the COS; wherein the storage area further comprises a public area, and the public area comprises a plurality of zones, each corresponding to a card organization and comprising related data for the card organization, and when the storage device is connected to an electronic device, the electronic device receives a selection of one of the card organizations, designates one of the zones in response to the selection, and accesses the related data from the designated zone via the microprocessor; and wherein the storage area further comprises a hidden area comprising a plurality of zones, each corresponding to one of the zones in the public area, and comprising a predetermined UID or keys, wherein the predetermined UID is used to authenticate the storage device, and the keys are used to encrypt the related data in the corresponding zone in the public area.
