Abstract

A portable storage device and a method for accessing data are disclosed. A control unit is coupled with a computer having a user authorization administrating system through a prearranged interface. The main body of the memory of the storage device is divided into area I, area II, and area III. The area I stores relative application programs, the area II is a public area for temporarily storing various commands and data, and the area III is a concealing area for storing the custom information. When the external wants to store data into the area III or accessing the custom information from the area III, the data waiting to accessed can be temporarily stored in the area II, and the particular reading/writing commands of the application program in the area I with the reading/writing level in the area I is simultaneously written into the area II and executed, so that the data temporarily stored in the area II can further be written into the area III or read by the external in order to finish the data accessing and exchanging process between the external and the memory.
