Description

Encrypted USB flash disk

Technical Field

The utility model relates to a USB flash disk technical field especially relates to encrypt USB flash disk.

Background

The USB flash disk is short for USB flash disk. The U disk is a type of flash memory and is sometimes referred to as a flash disk. The most difference between the U disk and the hard disk is that the U disk does not need a physical drive, is plug and play, and has storage capacity far exceeding that of a floppy disk, thereby being very convenient to carry. The U disk integrates the magnetic disk storage technology, the flash memory technology and the universal serial bus technology. The port of the USB is connected with a computer and is a data input/output channel; the main control chip makes the computer recognize the USB flash disk as a movable disk, which is the brain of the USB flash disk; the flash memory chip of the U disk stores data, and unlike the memory of a computer, the data cannot be lost even after power failure; the PCB backplane connects the components together and provides a platform for data processing.

The U disk is used more and more, but the existing U disk still has defects, because the existing U disk is mostly not provided with an encryption device, the USB flash disk can be used by any person, and when the stored information needs to be kept secret, the conventional U disk cannot encrypt the information; meanwhile, most of the U disks with the encryption function adopt encryption schemes with higher cost, such as fingerprint identification, facial identification and the like, so that the cost of the U disks is increased, and no better market exists.
