Embodiment 1

[0049] Such as figure 2 As shown, this embodiment mainly describes the common mobile storage mode.

[0050] Step S201, start.

[0051] In step S202, the computer is turned on, and the operating system of the computer runs normally, and the device 100 is inserted.

[0052] Step S203, check the computer equipment, add a virtual resource manager CD drive letter, and open the virtual resource manager in the CD.

[0053] Step S204, after the virtual resource manager 12a runs, select the super administrator login method, input the correct password, and after the virtual resource manager 12a interacts with the off-chip data storage module 20, obtain the data of the tool software unit 21 and the data storage unit 22 , and re-enumerate and load the removable storage device.

[0054] Step S205, check the computer equipment, there are three drive letters displayed in the operating system of the computer, which are virtual resource manager area, tool software area and data storage are...

Embodiment 2

[0059] Such as image 3 As shown, this embodiment mainly records the security and anti-leakage mode.

[0060] Step S301, start.

[0061] Step S302, turn on the computer, the operating system of the computer runs normally, and insert the device 100 .

[0062] Step S303, check the computer equipment, add a disk drive letter in the virtual resource manager area, and open the virtual resource manager in the CD.

[0063] Step S304, after the virtual resource manager 12a is running, select the user login method and input the correct password.

[0064] Step S305, the virtual resource manager 12a takes over the screen copying and screen display of the operating system of the computer, and runs in a maximized and foreground mode.

[0065] Step S306, the driver and service process in the virtual resource manager 12a isolates the permanent storage device, network device and various hardware ports on the computer motherboard except the device 100, including hard disk, optical drive, ne...

Abstract

The invention relates to a method and device for preventing read-write data from being copied. The method and device solve the technical problems that an existing data protection method is low in safety and is not flexible or convenient enough in use. The device comprises a CPU main control module, an off-chip data storage module, a clock module, a power module and a USB interface. The USB interface is connected with the CPU main control module, the off-chip data storage module is connected with the CPU main control module through a storage interface, and the clock module and the power module are respectively connected with the CPU main control module. The CPU main control module is a CPU chip provided with an on-chip program operation unit and an on-chip data storage unit, the on-chip data storage unit comprises a virtual resource manager, and the virtual resource manager comprises a file managing module. The off-chip data storage module is provided with a tool software unit and a data storage unit. The method and device for preventing the read-write data from being copied can be widely applied to the technical field of data protection.

Description

technical field [0001] The invention relates to a data protection method and device, in particular to a method and device for preventing readable and writable data from being copied. Background technique [0002] At present, data storage and distribution have always had two contradictory requirements: on the one hand, it is necessary to provide users with all data content through floppy disks, CDs, U disks, mobile hard disks, networks, etc., so that users can read documents, Functional operations such as running software; on the other hand, from the perspectives of data security, copyright protection, and prevention of reverse engineering, it is necessary to prevent users from being able to copy data content. The above technology is very important for the application fields of e-book copyright protection and readable and non-replicable confidential documents. Readers can read freely, but they cannot share the documents with others through electronic copying to prevent the sp...
