Abstract

The invention belongs to the technical field of electronic storage devices, and specifically provides a fingerprint identification U disk, including a U disk body, a USB interface, a display, a disk core, and a U disk, wherein the display is located on the surface of the U disk body, and the disk core is located on the U disk body. Inside, and the USB interface and the display are all electrically connected to the disk core. A fingerprint identification U disk provided by the invention, the U disk adopts fingerprint identification technology, and the data of the U disk can only be accessed after identification; There are connection contacts on both sides of the USB interface, so the front and back sides are not distinguished when using, which greatly improves the convenience of users; in addition to being used as an independent storage unit, the U disk can also be connected end to end to form a multi-partition storage system. The large-memory U disk can not only expand the memory, store different storage data separately, but also be convenient to carry. In addition, the U disk can display the remaining capacity and the type of stored data in time, which is convenient and practical.

Description

Technical field

[0001] The invention belongs to the technical field of electronic storage devices, and specifically relates to a fingerprint recognition U disk, which is accessed through fingerprint recognition. When connected and used, it does not need to distinguish between the front and the back. It can display the remaining capacity and the type of data stored in it in time, and can also convert The same U disk is connected end to end to form a U disk with larger memory. Background technique

[0002] In our work and study, we often use U disks for data storage, exchange and sharing. In many cases, personal privacy is stored. Now U disks on the market are directly accessible without any encryption processing. For most It seems very insecure for users.

[0003] We often encounter this kind of embarrassment. For example, you take a USB flash drive to copy data on someone else's computer, and sometimes it takes a long time to try to insert it. When you finally plug it in, you hav...

Embodiment Construction

[0015] Such as figure 1 with figure 2 A fingerprint identification USB flash drive is shown, including a USB flash drive body 1, a USB interface 2, a display 3, a core 4, a USB flash drive 5, a USB flash drive 6, a USB flash drive 7, and a USB flash drive 8. The display 3 is located on the USB flash drive body 1 On the surface, the core 4 is located inside the U disk body 1, which mainly includes the main control chip, flash memory chip and fingerprint recognition module, and the USB interface 2, the display 3 are electrically connected with the core 4; U disk 5, U disk 6, U disk 7 and U disk 8 are four identical U disks.

[0016] The main control chip uses the ML69Q6203 chip, which is a general-purpose single-chip microprocessor with ARM946E as the core, integrates the functions of the USB chip, and has a large-capacity Flash ROM; the flash memory chip uses the Samsung K9F5608U0A module. It has the advantages of 32MB capacity, fast reading and writing speed, long data storage ...
