Problems solved by technology
[0003] However, due to the popularity of portable flash storage devices, there are some unexpected issues, such as: when the user installs the drive device of the portable flash storage device on a device with user authority via the USB interface In the regulated operating system, the application of the device may need to use an application program in an "application programming interface (API; Application Programming Interface)" (in the above-mentioned Microsoft Windows operating system, it is called "small computer System interface application programming interface (SCSI API)"), however, the function of the application programming interface can only be used when logging in at the administrator level. Therefore, in the above operating environment, users who log in at the general user level The operator cannot fully drive the device normally; at the same time, for different Windows operating systems, the related portable flash storage devices do not operate in a single way, which also causes inconvenience in use

The invention relates to a portable storage and its data access method which mainly uses a control unit to couple with a computer with a user authority management operating system by an initialize surface. The memory of the storage is divided into the zones of 1, 2, and 3. It stores the corresponding application program in the zone 1; the zone 2 is a public zone which can temporarily store the instruction and the data; the zone 3 is a disguise zone which can preserve the data of the client. When the someone wants to store the data to or read the client data from the zone 3, it can temporarily store the accessed data in zone 2, and writes the special read-write instruction with read / write level application surface in zone 1 to the zone 2 and executes it at the same time, so that the temporary storage data of zone2 can be write to zone3 or red by the external to accomplish the data exchange and access movement with external.
Description
technical field [0001] The present invention relates to a portable storage device and a data access method thereof, in particular to a method applicable to logging in with a general user account with authority control (such as: Windows TM 2000, Windows TM NT, Windows TM XP or Windows TM 2003) Portable storage device and method for accessing data in operating system. Background technique [0002] With the development of the Internet, a variety of Internet browsing software continue to introduce new ones, among which Microsoft TM Windows TM System is a relatively popular operating system with the highest market share at present. However, because the backdoor program of the operating system has not been completely removed, it has become a medium of hacker intrusion, with various virus intrusions and spam emails. Derived problems continue, so that the general company's information management personnel must spend a lot of energy and time on computer management; in orde...
