Embodiment 1

[0029] Embodiment 1: A kind of confidential USB storage disk with display screen, it is characterized in that: comprise:

[0030] Flash encryption chip 1 is used to implement secure encrypted storage of user information. The stored data is stored in the Flash in the form of ciphertext. The key is randomly generated and placed inside the chip. Even if the data in the Flash is obtained, there is no The key is also an incomprehensible garbled code;

[0031] A security chip 3 with a USB interface 4 is used for data transmission with the Flash encryption chip 1, and is also used for verifying the PIN code input by the user through the buttons and the display screen 6, and the PIN code is passed to the user through the GSM module. The security chip, if successful, generates a verification code and sends it to the GSM module. If it is wrong, it prompts the user to re-enter, and compares the verification code information entered by the user. If it is correct, it starts the USB storage...

Embodiment 2

[0036] Embodiment 2: a kind of confidential USB storage disc with display screen, comprises Flash encryption chip 1, memory interface 2, security chip 3, USB interface 4, GSM module 5, button and display screen 6, it is characterized in that: wherein Flash encryption The chip 1 is connected with the security chip 3 through the memory interface 2, the GSM module 5 is connected with the security chip 3 and the keys and the display screen 6 through the I / O port for data interaction, and the USB interface 4 is connected with the security chip through 4 side wires. 3 connections. The USB interface 4 is connected to the security chip through 4 side wires, and is responsible for connecting to the computer, and the middle two are data lines, which are data input or output channels, and are responsible for supplying power to the U disk and realizing communication with the computer.

[0037] The keys of the control 6 of the confidential USB storage disk are divided into five control key...

Abstract

The invention relates to a confidential USB (universal serial bus) memory disk with a display screen and a security control method of the confidential USB memory disk, which aim to solve the problem of information leakage due to USB mobile memory devices. The confidential USB memory disk comprises a Flash encryption chip, a memory interface, a security chip, a USB interface, a GSM (global system for mobile communications) module, keys and the display screen, the Flash encryption chip is connected with the security chip by the memory interface, the GSM module is respectively connected with the security chip, the keys and the display screen by I / O (input / output) ports to realize data interaction with the security chip, the keys and the display screen, and the USB interface is connected with the security chip by four edge joint lines. The confidential USB memory disk with the display screen not only has a memory function of a common USB flash disk, but also has a password protection function of the USB flash disk.

Description

Technical field [0001] The invention is a field of information security technology, which involves a confidential USB storage disk and its security control method designed to solve the problem of information leakage caused by the USB mobile storage device. Background technique [0002] With the widespread application of the U disk (including the U disk, mobile hard disk, etc.), people are accustomed to store a large number of files in the U disk and pass the files casually through the U disk.The general U disk does not have the function of encryption. Anyone can see the content of it through the U disk. At the same time, the small volume of the unique disk is easy to lose.Use at will. [0003] Traditional U disks have no user needs for data storage.With the frequent disclosure of corporate secrets, theft of customer information, and various "door events" on the Internet, the security of the data has also been pushed to the cusp, and consumers' awareness of data information has in...
