Description

Mobile storage device data access method and system

The present invention relates to a mobile storage device management method and system, and more particularly to a mobile storage device data access method and system.

Nowadays, in the era of informationization, mobile storage devices are becoming more and more important as important media for mobile storage, but often there are important information leaks due to loss or poor management of mobile storage devices. Generally, there is a write-protected switch on the mobile storage device casing. Although this switch can protect the mobile storage device from being able to write data, it can also access the entire contents of the mobile storage device. There are also mobile storage devices that use fingerprint recognition, user information verification, and storage protection devices in the mobile storage device enclosure to control access to the mobile storage device, but these methods are complex and require more devices to be added.

In view of the above, it is necessary to provide a mobile storage device data access method and system.

The storage area is set to be inaccessible.

The mobile storage device data access system includes: a receiving module, configured to receive an access instruction sent by the electronic device when the mobile storage device is connected to the electronic device; and a determining module, configured to determine that the switching circuit of the mobile storage device is in an open state Or the off state; the module is opened, when the switch circuit of the mobile storage device is in the off state, the open control signal is turned on to open the switch circuit; and the access module is configured to access the visible storage area and hide when the switch circuit is in the open state The data in the storage area; and the shutdown module is configured to send a shutdown control signal to close the switch circuit when the data access is completed, and set the hidden storage area to an inaccessible state.

The invention realizes the data security of the mobile storage device by controlling the access permission of the hidden storage area of the mobile storage device through a switch circuit.

3 is a flow chart of a preferred embodiment of a method for accessing data of a mobile storage device of the present invention.

Referring to FIG. 1, a diagram of an operating environment of a preferred embodiment of a data storage system for a mobile storage device of the present invention is shown. The mobile storage device data access system 10 is operated on a mobile storage device 1. The mobile storage device 1 can be connected to the electronic device 2 through a data interface (eg, a USB interface) to implement data transmission. The mobile storage device 1 can For a USB flash drive, a mobile hard disk, etc., the electronic device 2 can be a computer, a tablet computer, a smart phone, or the like.

The mobile storage device 1 further includes a storage 12, a processor 14, and a switching circuit 16.

The storage 12 can be configured as two storage areas, that is, the storage area 120 and the hidden storage area 121. The data in the visible storage area 120 is allowed to be freely accessed, and the data of the hidden storage area 121 is allowed to be accessed only when the switching circuit 16 of the mobile storage device 1 is in the on state.

The switch circuit 16 is configured to control access permission to the data of the hidden storage area 121. When the switch circuit 16 is turned on, the data of the hidden storage area 121 is allowed to be accessed. When the switch circuit 16 is turned off, the storage area 121 is hidden. The information is not allowed to be accessed.

In this embodiment, the mobile storage device data access system 10 can be divided into one or more modules, and the one or more modules are configured to be one or more processors (this embodiment is a The processor 14) executes to complete the present invention. For example, as shown in FIG. 2, the mobile storage device data access system 10 is divided into a receiving module 100, a determining module 102, an opening module 104, an access module 106, and a shutdown module 108. The module referred to in the present invention is a program segment that performs a specific function, and is more suitable for describing the execution process of the software in the mobile storage device 1 than the program. For the function of each module, refer to the description of FIG.

Referring to FIG. 3, it is a flow chart of a preferred embodiment of the method for accessing data of the mobile storage device of the present invention.

In step S10, when the mobile storage device 1 is connected to the electronic device 2, the receiving module 100 receives the access command sent by the electronic device 2.

In step S11, the determining module 102 determines whether the switch circuit 16 is in the on state or the off state. When the switch circuit 16 is in the on state, the process proceeds directly to step S13.

In step S12, when the switch circuit 16 of the mobile storage device 1 is in the off state, the open module 104 sends an open control signal to open the switch circuit 16. In this embodiment, when the switch circuit of the mobile storage device 1 is in the off state, the open module 104 prompts the user to hide the storage area 121 in an inaccessible state in a dialog box, and asks the user whether to hide the current time. The storage area 121 is placed in an accessible state. When the user selects to place the hidden storage area 121 in an accessible state, the opening module 104 sends an open control signal to open the switch circuit 16.

In step S13, the access module 106 accesses the data in the visible storage area 120 and the hidden storage area 121.

In step S14, when the data access is completed, the shutdown module 108 sends a close control signal to close the switch circuit 16, so that the hidden storage area 121 is in an unreachable state. In other embodiments, when the mobile storage device 1 is disconnected from the electronic device, the shutdown module 108 sends a shutdown control signal to close the switch circuit 16 to place the hidden storage area 121 in an unreachable state. In this embodiment, when the mobile storage device 1 is disconnected from the electronic device, the user may be queried in the form of a dialog box to reset the hidden storage area 121 to an unreachable state. When the user selects to hide the storage area 121, After being set to the inaccessible state, the shutdown module 108 sends a shutdown control signal to close the switch circuit 16 so that the hidden storage area 121 is in an unreachable state.

The step S10 to the step S14 control the access permission of the hidden storage area 121 of the mobile storage device 1 through a switch circuit, thereby realizing the data security of the mobile storage device.

The above embodiments are merely illustrative of the technical solutions of the present invention and are not intended to be limiting, although the present invention will be described in detail with reference to the preferred embodiments, those skilled in the art should understand Modifications or equivalents are made without departing from the spirit and scope of the invention.
