Problems solved by technology

[0003] When the ordinary U disk is in use, its data storage area can be directly recognized, read and written by the host computer. There are five security risks in the use of this traditional U disk: First, the operation of the U disk does not require authentication. The internal data will be fully exposed; second, ordinary U disks cannot record the user's operation behavior, and cannot audit, collect evidence and track security events
The third is that the data in the disk may be stolen by a Trojan horse virus or a backdoor program; the fourth is that the U disk may be infected by a virus in the host machine, making it a new source of infection; "Secret" and "non-secret" are mixed

Embodiment 1

[0023] see Figure 1-4 , in an embodiment of the present invention, a multi-functional USB storage device, including a device body, is characterized in that the device body is provided with a document data storage area for storing data and for docking with a PC terminal for managing document data A dedicated resource management module for storage area data, the device body is also provided with a status detection module for docking with the dedicated resource management module; the status detection module includes a locking module for locking the document data storage area and is located on the device body And a full-digit input keyboard communicating with the locking module, the locking module is provided with an instruction comparison module for judging whether the instructions entered by the keyboard match, and when the firmware verifies the password entered by the user, it will save the document data storage area of ​​the device Set it to an unlocked state, and save the ve...

Embodiment 2

[0043] The difference from Embodiment 1 is that the authority unit includes a pre-stored indwelling feature code and a comparison execution unit that obtains the feature code on the PC side and compares the acquired feature code with the indwelling feature code, and the authority unit is used by the PC The terminal detection module retrieves and obtains and establishes an interactive pre-stored retention feature code.

[0044] There are two restriction modes for restricting the scope of use of the device: one is to limit the device as the main body, and set the terminals that it can use; the other is to limit the terminal as the main body, and set the devices that it can use. This function is realized by the combination of permission setting tool and special resource manager software.

[0045] The limitation with the device as the main body is that the authorization setting tool writes the characteristic code of the authorized host into the configuration storage area of ​​the ...

Abstract

The invention discloses a multifunctional USB storage device. The multifunctional USB storage device includes a device body; a document data storage area used for storing data and a special resource management module which is in butt joint with the PC terminal and used for managing data in the document data storage area are arranged in the device body. A state detection module for detecting whether device body is butted with the special resource management module or not is also arranged in the device body; according to the invention, improvement is carried out aiming at defects in the prior art; multiple technical measures are adopted, various safety functions such as hardware password authentication, storage space isolation, data encryption, file read-write control, user behavior tracingand use range limitation are realized, so that the mobile storage equipment not only can meet the requirements of industries (users) with higher confidentiality in the aspect of safety and secrecy, but also can bring convenience in the aspect of data exchange into play.

Description

technical field [0001] The invention relates to the technical field of storage devices, in particular to a multifunctional USB storage device. Background technique [0002] U-disk, the full name of USB flash drive, the English name "USB flash disk". It is a miniature high-capacity mobile storage product that uses a USB interface and does not require a physical drive. It is connected to a computer through a USB interface to achieve plug-and-play. The name of the U disk originated from a new type of storage device produced by Netac Technology, named "U disk", which is connected with a USB interface. After the U disk is connected to the USB interface of the computer, the data of the U disk can be exchanged with the computer. Since Netac has registered patents for equipment with similar technologies produced later, they can no longer be called "USB disks", but are renamed "U disks" with homophonic sounds. Later, the name U disk was widely known because of its simplicity and e...
