`
`Technical Field
`
`
`
`
`
`The present utility model relates to a USB device, in particular to an automatically
`
`running composite USB device with a mass storage and a fingerprint lock.
`
`
`
`Background Art
`
`
`
`Fingerprint recognition technology is the earliest computer-based identification method,
`
`and it is still the most widely used biometric technology today. In the past, it was mainly used in
`
`the criminal investigation systems. In recent years, it has gradually moved to a wider civilian
`
`market. As early as in ancient times, humans have recognized the characteristics of fingerprints
`
`and have used fingerprints as a symbol of personal identity. In the middle of the 19th century,
`
`scientists began scientific research on the true meaning of fingerprints, and reached two
`
`important conclusions: 1. No two fingers have identical fingerprints; 2. the shape of the
`
`fingerprint remained unchanged for life. These studies had led some governments to use
`
`fingerprints for criminal identification. In the field of modern scientific research, the
`
`identification of fingerprints belongs to “pattern recognition”. At the core of this fingerprint
`
`recognition system is the OCR (Optical Character Recognition) technology. Fingerprint is
`
`extracted by a CMOS (Complementary Metal Oxide Semiconductor) camera, then input into a
`
`computer, and goes through a series of complex fingerprint recognition algorithms. Modern
`
`technology can complete any person’s identity authentication in a very short time. Thus, it can be
`
`said that fingerprint recognition is the revolution of the century in the field of identity
`
`identification.
`
`
`
`
`
`With the continuous development of USB KEY technology, a USB information security
`
`lock based on fingerprint acquisition and recognition has emerged, which is referred to as a
`
`fingerprint lock or fingerprint KEY. The fingerprint KEY is a personal mobile security product
`
`based on the fingerprint recognition technology. It scans the human fingerprint through an
`
`optical sensor, and a user does not need to input a PIN code. It can achieve reliable strong two-
`
`
`
`
`
`IPR2020-00341 Page 00006
`
`

`

`factor identity authentication by virtue of fingerprint plus hardware. The fingerprint KEY can be
`
`built into a 32-bit core intelligent card chip, a high-performance fingerprint processing chip, and
`
`a scanning live fingerprint image sensor. The processes of fingerprint collection, storage and
`
`verification are performed entirely in the KEY, that is, the user’s fingerprint information and key
`
`will never appear in the computer’s memory, and the user’s personal data can be protected safely
`
`and effectively. The fingerprint KEY has a built-in RSA algorithm; the hardware generates a
`
`1024-bit or 2048-bit RSA key pair, a 64K user storage space is provided; it supports PKCS#11
`
`and CSP standard middleware, and fully supports a PKI application.
`
`
`
`
`
`A USB mass storage device is a portable mobile storage device that has emerged in
`
`recent years; it is characterized by small size, low price, being easy to carry, stable performance,
`
`large storage capacity (ranging from tens of megabytes to several gigabytes and extendable. It
`
`can completely replace the functions of floppy disk and floppy disk drive. Like the fingerprint
`
`KEY, the USB mass storage device uses a USB interface, and the storage medium can be Flash
`
`Memory, EPROM, EEPROM, MRAM or FRAM. USB mass storage devices can be used to store
`
`various types of data files, drivers, and applications. With the continuous development of the
`
`USB mass storage device technology, USB mass storage devices using the Autorun technology
`
`have appeared on the market. After a USB mass storage device is connected to a computer, the
`
`specified program or file can automatically run, such as automatically playing Flash animation,
`
`video advertisement, PPT presentation, web page display and automatic link login. With a
`
`management tool, a user can switch the content that is automatically run, or can set the order and
`
`mode of execution or display of each file. The importable contents include: movie files (AVI,
`
`WMV, ASF, DAT), presentation files (PPT), OFFICE files (WORD, EXCEL, etc.), image files
`
`(BMP, JPG), executable files (EXE), FLASH files. (SWF), sound files (WAV, MP3), web page
`
`files (HTML), web addresses, and the like. Programs or files will be terminated immediately
`
`after the USB mass storage device is unplugged, and no information will be left on the computer,
`
`making it easy, efficient, and secure.
`
`
`
`
`
`However, the fingerprint KEY typically only has a single function and limited storage
`
`capacity, which cannot meet the increasing storage requirements. Although USB mass storage
`
`devices have large storage capacity, in general, the data in USB mass storage devices are
`
`
`
`
`
`IPR2020-00341 Page 00007
`
`

`

`unencrypted. Thus, the fingerprint KEY can be used to encrypt data in the USB mass storage
`
`device. In addition, sometimes it is necessary to install the fingerprint KEY driver through a CD
`
`or a network, such that the fingerprint KEY can be recognized by the computer, which may bring
`
`a lot of inconvenience to the user. At present, more and more users need a composite portable
`
`device that can be used as an identity authentication terminal, has certain storage capacity, and
`
`has the Autorun function.
`
`

`
`
`
`Description of the Embodiments:
`
`
`
`The device of the present utility model mainly comprises two parts in the hardware
`
`structure, namely a fingerprint KEY and a USB mass storage device. The content of the present
`
`utility model will be described in detail below in conjunction with specific embodiments.
`
`
`
`
`
`
`
`Embodiment 1 is shown in FIG. 1, which is composed of a USB interface 102, a USB
`
`HUB module 103, a USB KEY controller 104, a fingerprint KEY unit 105, a USB mass storage
`
`device controller 106, a mass storage unit 107, and an automatic running circuit 108. The
`
`fingerprint KEY unit 105 is connected to the USB HUB module 103 through the USB KEY

`

`IPR2020-00341 Page 00010
`
`

`

`
`
`As shown in FIG. 2, embodiment 2 is composed of a USB interface 202, a USB HUB
`
`module 203, a USB KEY controller and a fingerprint KEY integration module 204, a USB mass
`
`storage device controller 205, a mass storage unit 206, and an automatic running circuit 207. The
`
`USB KEY controller and the fingerprint KEY integration module 204 (i.e., the fingerprint lock
`
`application sub-module) are connected to the USB HUB module 203, and then connected to the
`
`USB interface 202 through the USB HUB module 203, and finally connected to the host 201
`
`through the USB bus, to implement the function of the fingerprint KEY. At the same time, the
`
`mass storage unit 206 is connected to the USB mass storage device controller 205, and the USB
`
`mass storage device controller 205 is in turn connected to the automatic running circuit 207, and
`
`then connected to the USB interface 202 through the USB HUB module 203, and finally
`
`connected to the host 201 through a USB bus, to implement the function of USB mass storage
`
`device. The mass storage unit 206, the USB mass storage device controller 205, and the
`
`automatic running circuit 207 collectively constitute a mass storage application sub-module. In
`
`this embodiment, the fingerprint KEY and the USB mass storage device are coupled together by
`
`a USB HUB module, wherein the USB KEY controller and the fingerprint KEY unit are
`
`integrated into one chip. The feature of this embodiment is that it can save some costs, and the
`
`disadvantage is that the execution speed is slightly slower.
`
`
`
`The flow of the interaction operation with the host in embodiments 1, 2 of the present
`
`invention is as shown in FIG. 4: in step 401, the device of the present invention is inserted into
`
`the host, and each work is started. First, in step 402, a command is issued by the host. In step
`
`403, the USB HUB determines which device command is used, and the USB HUB sends the host
`
`command to different devices according to different device numbers. If it is a command of the
`
`mass storage device, step 404 is executed to determine whether it is the first bus reset, and if so,
`
`step 405 is performed to enumerate the mass storage device. Step 406 reports the system
`
`descriptor as a CD ROM. Step 407 searches if there is an Autorun.inf file, and if so, executes
`
`step 408 to run the Autorun.inf file. Then, step 409 is performed to perform USB enumeration
`
`again. If the Autorun.inf file does not exist, step 409 is directly performed to re-enumerate the
`
`USB device. Step 410: the mass storage device receives the command sent by the host in step
`
`402 and parses the command. Next, the step 411 performs data exchange. The data exchange
`
`
`
`
`
`IPR2020-00341 Page 00011
`
`

`

`includes receiving data of the host and returning internal data of the mass storage device to the
`
`host, including reading of the file allocation table. Finally, at step 412, the information is
`
`returned to the host. If it is determined in step 404 that the USB peripheral is not the first bus
`
`reset, then step 410 is directly executed to receive the host command and parsed without re-
`
`enumerating the USB device. In step 403, if it is a fingerprint KEY, the fingerprint KEY data
`
`branch is executed. Step 413 performs USB device enumeration. In step 414, the fingerprint
`
`KEY receives the data and parses it. Step 415 processes information internally, including
`
`receiving data and transmitting data, encrypting and decrypting data, verifying password
`
`information, verifying biometrics, verifying signatures, etc., as well as storing passwords, storing
`
`certificates, storing biometrics, and setting authority settings activity. Step 416 organizes the
`
`processed information. Step 417 returns the data information to the host.
`
`
`
`In embodiment 3, as shown in FIG. 3, the device of the present invention is composed of
`
`a USB interface 302, a composite controller module 303, a fingerprint KEY unit 304, a mass
`
`storage unit 305, and an automatic running circuit 306. The fingerprint KEY unit 304 is
`
`connected to the composite controller module 303, and the composite controller module 303 is
`
`connected to the automatic running circuit 306, and then the automatic running circuit 306 is
`
`connected to the USB interface 302. Finally, it is connected to the host 301 through the USB bus
`
`to implement the function of the fingerprint KEY. At the same time, the mass storage unit 305 is
`
`connected to the composite controller module 303, which is in turn connected to the automatic
`
`running circuit 306, and is connected to the USB interface 302 through the automatic running
`
`circuit 306. Finally, it is connected to the host 301 through the USB bus in order to implement
`
`the function of the USB mass storage device. The embodiment integrates a fingerprint processing
`
`KEY unit and a micro processing unit for controlling the mass storage unit through a composite
`
`controller module to simultaneously control the fingerprint KEY unit and the mass storage unit,
`
`thereby coupling the fingerprint KEY and the USB mass storage device. Together, the composite
`
`controller module is a composite chip with dual control functions of fingerprint KEY and USB
`
`mass storage device. The feature of this embodiment is that the fingerprint KEY and the USB
`
`mass storage device are directly connected to the USB interface, thereby improving the
`
`execution speed. On the other hand, since the USB HUB is not used, the cost is also saved.

`IPR2020-00341 Page 00012
`
`

`

`The working process of embodiment 3 is as shown in FIG. 5. The flow of the interaction
`
`with the host in the third embodiment of the present invention is as follows: Step 501: after the
`
`utility model is connected to the host, the operation is started, and the host sends a command in
`
`step 502. Step 503 then determines if the USB peripheral is the first bus reset. If yes, step 504
`
`performs hardware initialization USB enumeration to establish connection with the host. If it is
`
`not inserted into the host for the first time, no USB enumeration is performed. In step 505, the
`
`device reports the USB descriptor as a CD ROM. Step 506 searches if there is an Autorun.inf file,
`
`and if so, executes step 507 to run the Autorun.inf file. Next, in step 508, the USB device is re-
`
`enumerated, and the device descriptor is enumerated as a mass storage device or fingerprint KEY.
`
`If the search for the Autorun.inf file does not exist in step 506, then step 508 is directly
`
`performed to re-enumerate the USB device. Next, the USB device will work normally. Step 509
`
`needs to receive USB data and analyze the content of the data. Then, step 510 determines the
`
`working state of the system according to the obtained parsed data. If it is a mass storage device
`
`command, step 511 needs to further analyze the data to determine whether to enumerate the file
`
`allocation table (after the device is inserted into the host, the host enumerates a large amount of
`
`file partition tables of the storage device). If the file allocation table needs to be enumerated, step
`
`513 is executed to establish a virtual device on the host for the removable storage. If the file
`
`partition table of the device has been read, step 512 transfers the file normally, and finally returns
`
`data to the host in step 516. If the step 510 analysis is fingerprint KEY data, then the processing
`
`of the command is required at step 514. Data is collated by step 515, and then the data is returned
`
`to the host in step 516. If it is determined in step 503 that the USB peripheral is not the first bus
`
`reset, then step 509 is directly performed to receive the data and then parse the data, and it is not
`
`necessary to perform several steps 504-508.
`
`
`
`The present utility model implements the Autorun function by running the Autorun.inf
`
`file. The principle of the Autorun function is to allocate a part of the storage area of the USB
`
`mass storage device for storing the Autorun.inf file. After the device is plugged in, the computer
`
`recognizes it as two parts: the CD ROM and the disk storage, where the Autorun.inf file is stored
`
`on the CD ROM and data cannot be written to the portion, and the disk storage portion is used to
`
`store large amounts of data.
`
`
`
`
`
`
`
`IPR2020-00341 Page 00013
`
`

`

`In order to implement the automatic running function, the utility model first reports the
`
`system descriptor as a CD ROM when initializing the enumeration, so that the system can
`
`execute the Autorun.inf file, and the system needs to re-enumerate the USB device after the
`
`automatic running function is completed. It is implemented by the automatic running circuit
`
`shown in FIG. 6. Taking embodiment 1 as an example, the automatic running circuit is formed
`
`by a transistor P and a resistor R1. The base of the transistor is connected to a control terminal
`
`IO0 of the controller U1 for receiving an enumeration control signal. The emitter is connected to
`
`the power source Vcc, and the collector is connected to the data terminal, the D+ terminal of the
`
`USB interface J1 via the resistor R1. When the device of the present invention is connected to
`
`the host 101, the IO0 of the controller is low, and the voltage VA of the A point is high level. The
`
`device is in a state of being plugged. At this time, USB enumeration is performed, and the device
`
`reports the descriptor as a CD ROM. To perform the automatic running function, the next step is
`
`to re-enumerate the device of the utility model, set IO0 to high, the voltage VA at point A is low,
`
`the USB device is pulled out, and then IO0 is set to low, voltage VA at point A is at high level,
`
`the device is in the inserted state, which is equivalent to the operation of re-inserting after the
`
`device is pulled out, and then the second enumeration is performed according to the command
`
`issued by the host 101, and the device descriptor is reported as a USB mass storage device or
`
`fingerprint KEY. When the enumeration is initialized, the utility model first reports the system
`
`descriptor as a CD ROM, so that the system can execute the Autorun.inf file. After the
`
`completion, the system needs to re-enumerate the USB, and the device descriptor is reported as
`
`the fingerprint KEY or USB mass storage device for automatic running.
`
`
`
`The above describes an automatically running composite USB device with mass storage
`
`and fingerprint lock as provided by the present utility model. In this disclosure, the specific
`
`examples are used to explain the principle and implementation of the present utility model. The
`
`description of the above embodiments is only for helping to understand the method of the present
`
`invention and its core idea; at the same time, for a person of ordinary skill in the art, in
`
`accordance with the basic idea of the present utility model, there may be changes in specific
`
`embodiments and applications. In summary, the content of the description should not be
`
`construed as limiting the present utility model.
