A secure usb flash drive based on wifi signal detection

Abstract

A secure USB flash drive based on WiFi signal detection, comprising a main control module, a switch, a storage module, a power module, a WiFi module and a USB interface; the storage module is connected to the switch for storing data; the WiFi module is used for connecting Designate the AP and obtain its signal strength; the switch is connected with the main control module and the USB interface to make the storage module connect to the main control module or the USB interface; the main control module is connected with the WiFi module and is used according to the AP connection and signal strength. Control the action of the switch to enter different modes; the power module is connected with the main control module, the switch and the storage module to supply power. The present invention can effectively prevent data leakage caused by equipment loss.

Description

technical field [0001] The invention relates to the field of electronic secret-related carriers, in particular to a secure USB flash drive based on WiFi signal detection. Background technique [0002] With the rapid development of information today, mobile storage devices have gradually become an indispensable tool in life and work, and storage devices are almost always used as tools for carrying data. At present, the most widely used storage device is the U disk. U disk has become the enduring darling of the storage industry because of its advantages of supporting hot swap, mini size, large storage capacity, low price, low power consumption, convenient and easy to carry, and fast reading and writing. [0003] As a necessity in work, U disk is always lost accidentally. If a U disk without any security measures is lost, the consequences are unimaginable. As long as you get the U disk, for more important data or private information, Anyone can read, so U disk is very importa...

Problems solved by technology

This kind of technology is ever-changing and cannot solve the threat from many hacking software such as various Trojan horses and keylogging software inside the computer. At the same time, there are many hardware stealing devices when typing passwords and data, and hardware hacking during transmission. For example, Hardware keyloggers, etc., the dangers of these two aspects cannot be solved by existing technologies

In addition, flash drives are at risk of being stolen when storing data, reading, writing, modifying data, and exchanging data with other people, which will bring losses to users.

[0005] At the same time, encryption software conflicts with other software in the computer and may be deleted as a virus. The cost of the hardware-encrypted flash disk control chip itself is high, and the adaptability to general-purpose memory chips is poor, which makes this type of hardware-encrypted flash disk more difficult. High cost, not conducive to promotion
