Embodiment

[0045] Embodiment, a kind of U disk data protection system based on real-time multi-party interactive authentication, such as figure 1 As shown, the interactive device includes a USB flash drive 1 and a mobile terminal 2, and the USB flash drive 1 and the mobile terminal 2 communicate through Bluetooth to protect the data of the USB flash drive 1. Bluetooth is a radio technology that supports short-distance communication between devices. When the distance between the mobile terminal 2 and the U disk 1 is about 10 meters, the communication between the mobile terminal 2 and the U disk 1 will be terminated.

[0046] Specifically, the USB flash drive 1 includes a main control chip 11 , a storage chip 12 , a connection interface 13 and an encrypted Bluetooth module 14 . Wherein the storage chip 12, the connection interface 13 and the encryption bluetooth module 14 are all connected on the main control chip 11, and the quantity of the encryption bluetooth module 14 can be one or two...

Abstract

The invention discloses a USB flash disk data protection system and method based on real-time multi-party interactive authentication, and relates to the technical field of USB flash disk security. According to the technical key points, the USB flash disk data protection system includes a USB flash disk; the USB flash disk comprises a main control chip, a storage chip, a connecting interface and anencrypted Bluetooth module; the main control chip is connected with the encrypted Bluetooth module and receives information of a communication state of the encrypted Bluetooth module; the main control chip is connected with the storage chip so as to control whether the storage chip is in a disk falling state or not; a decryption Bluetooth module with an encryption Bluetooth module communication key is arranged in the mobile terminal; after the encryption Bluetooth module and the decryption Bluetooth module communicate with each other, the mobile terminal and the USB flash disk send heartbeatpackets to achieve continuous communication, the main control chip controls sending of a disk dropping command or a disk loading command to the storage chip based on receiving of the communication state information of the encryption Bluetooth module, the USB flash disk is switched to a disk dropping state or a disk loading state, and the USB flash disk data protection system and method have the advantage of improving USB flash disk data protection.

Description

technical field [0001] The invention relates to the field of U disk security technology, more specifically, it relates to a U disk data protection system and method based on real-time multi-party interactive authentication. 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 without a physical drive. Now there are many U disks that support multiple ports on the market, that is, three-way U disks (USB computer port, iOS Apple interface, Android interface) . [0003] As a storage medium, the USB flash drive often stores a lot of work data, and sometimes there are some confidential data. Due to the small size of the USB flash drive, it is often forgotten to remove it from the computer after use. In this case, The data on the USB flash drive may be stolen, causing losses to the business. Contents of the invention [0004] In view of the exi...
