Example Embodiment

[0016]

[0017] In the present invention, the fingerprint scanning module (2) is installed on the surface of the U disk (1), and the interface (3) is installed at the end of the U disk (1).

[0018] Before packaging, the present invention has built-in fingerprint authentication module, COS module, and storage module. Specifically, it also includes SD / SDIO module, encryption and decryption module, NandFlash management module and NandFlash medium. Among them, the SD / SDIO module passes the encryption and decryption module and COS. The module is connected to the NandFlash management module and then to the NandFlash storage medium. The fingerprint authentication module is connected to the COS module and the fingerprint scanning module (2).

[0019] There are public partitions, encrypted partitions and private partitions on the NandFlash media, and the NandFlash management module is respectively connected to the public partition, encrypted partition and private partition of the NandFlash m...

Abstract

The way of forming an intelligent digital U disk which is based on fingerprint encryption is as follows, installing a fingerprint scanning module (2) on the surface of the U disk (1), installing an interface (3) on the end portion of the U disk (1), and internally arranging a fingerprint authentication module, a COS module, and a memory module. Furthermore, the internal structure of the U disk specifically includes a SD/SDIO module, an encryption/decryption module, a NandFlash management module, and a NandFlash medium, wherein the SD/SDIO module is connected to the NandFlash management module through the encryption/decryption module and the COS module and then connected to the NandFlash medium in turn, and the fingerprint authentication module is connected to the COS module and the fingerprint scanning module (2). A fingerprint scanning window is installed and a user's fingerprint is preset in a starting system. The U disk can be used after going through user fingerprint authentication when the user opens the U disk. Files can further be encrypted by adopting password reading. Intelligent software embedded coordinates work of data scheduling, enabling the data to be safer and improving privacy and security of the U disk significantly.

Description

technical field [0001] The invention relates to a G11C static memory technology or equipment in the International Patent Classification, which belongs to the technical field of information storage security, in particular to fingerprint-encrypted intelligent digital U disk storage security. Background technique [0002] In recent years, mobile digital storage devices have become portable, and related products are abundant and increasingly popular. Now, no matter students or people in any industry will carry a mobile storage device with them, ranging from flash memory cards to mobile hard drives, or installed in mobile phones. It can be placed in a bag or hung on a key chain, but the USB flash drive is still used as a daily storage of work data. With its advantages of large capacity, small size, and fast reading speed, it has become the main storage device for portable storage. However, because its content mostly involves confidential information related to important interests...
