[0033] Based on this, the embodiment of the present application provides a biometric fingerprint recognition system, referring to Figure 1 , Figure 1 This is a module diagram of the biometric fingerprint recognition system of this application.

[0034] The biometric fingerprint recognition system is connected to the terminal device and includes:

[0035] A data conversion unit is used to encrypt the accessed biometric fingerprint information based on the accessed fingerprint password to obtain the target biometric fingerprint information; and an identification calculation unit connected to the data conversion unit is used to identify the accessed target biometric fingerprint information and transmit the identification result to the terminal device.

[0036] Conventional biometric fingerprint recognition devices are deployed in terminal devices and directly transmit the collected biometric fingerprint information to the terminal device for identity authentication. However, because the biometric fingerprint recognition device and the terminal device in which the biometric fingerprint recognition system is located are two independent devices that need to be connected via a cable or connector, the biometric fingerprint information is extremely vulnerable to being stolen and leaked during the process of being transmitted to the terminal device, resulting in the loss of biometric fingerprint information and the loss of terminal device security.

[0037] Therefore, based on the above problems, this embodiment proposes the following Figure 1The novel biometric fingerprint recognition system shown is set in a biometric fingerprint recognition device, and the novel biometric fingerprint recognition system includes a data conversion unit for encrypting the biometric fingerprint information collected and identified, and an identification calculation unit for identifying the target biometric fingerprint information after the encryption operation and generating a corresponding identity recognition result.

[0038] Specifically: the data conversion unit encrypts the incoming biometric fingerprint information based on the accessed fingerprint password to obtain the target biometric fingerprint information, and transmits the target biometric fingerprint information to the identification and calculation unit. After the identification and calculation unit decrypts and identifies the target biometric fingerprint information, the identification result is transmitted to the terminal device through the data conversion unit, avoiding the problem of theft caused by directly transmitting the biometric fingerprint information directly to the terminal device for identity authentication. At the same time, the data conversion unit encrypts the accessed biometric fingerprint information, avoiding the risk of information loss during information interaction with the identification and calculation unit, and further improving the security of the biometric fingerprint information during information transmission.

[0039] Specifically, refer to Figure 2 As shown, the data conversion unit includes a conversion board and a fingerprint collector, and the fingerprint collector establishes a connection relationship with the conversion board.

[0040] according to Figure 2 As can be seen, the data conversion unit in this embodiment is equipped with a conversion board and a fingerprint collector. The conversion board is used to achieve compatibility and connection between different devices or interfaces on the data conversion unit, while the fingerprint collector is used to identify and collect the biometric fingerprint corresponding to the user identity to be identified and generate the corresponding biometric fingerprint information.

[0041] Furthermore, the fingerprint collector is a semiconductor fingerprint sensor, which is provided with a sensing area for capturing biometric fingerprint information. The sensing area is a sensing array composed of multiple sensing pixels, and the sensing area is arranged on the front of the biometric fingerprint recognition system.

[0042] The fingerprint collector used in this embodiment is specifically a capacitive press-type semiconductor fingerprint sensor, the sensing area of ​​which includes a sensing array with a length of 1.28 cm and a width of 1.50 cm composed of multiple sensing pixels. The pixels of the sensing array are 256*300 and have a resolution of 500DPI, which can accurately identify and collect fingerprints pressed on the sensing area.

[0043] At the same time, the semiconductor fingerprint sensor is also equipped with a liveness detection algorithm that can identify non-human fingerprints, such as fingerprint covers and fingerprint films, thereby improving the fingerprint recognition capability of the biometric fingerprint recognition system.

[0044] It should be noted that the front side in this embodiment refers to the side facing the user, which is convenient for the user to press the fingerprint.

[0045] Furthermore, a first USB (Universal Serial Bus) interface is provided on the conversion board. The first USB interface is used to access a USBKey interface. The USBKey interface is used to access a password module. The password module is used to input a fingerprint password into the conversion board.

[0046] based on Figure 2 It can be seen that the conversion board in this embodiment is provided with a first USB interface, and the first USB interface is used to access a USBKey interface so as to access a password module on the data conversion unit.

[0047] The password module stores password information. When the identification and calculation unit recognizes that the fingerprint collector connected to the conversion board collects biometric fingerprint information through the connection between the identification and calculation unit and the data conversion unit, the identification and calculation unit controls the password module to encrypt the biometric fingerprint information according to the password information stored therein, thereby ensuring the transmission security when the data conversion unit transmits the biometric fingerprint to the identification and calculation unit.

[0048] At the same time, after receiving the encrypted target biometric fingerprint information, the recognition and calculation unit can decrypt the target biometric fingerprint information based on the password information obtained from the password module, so as to identify the identity information corresponding to the biometric fingerprint information.

[0049] Furthermore, a TF (Trans-Flash) card interface is provided on the conversion board, and the TF card interface is used to access a TF card slot, and the TF card slot is used to insert the password module.

[0050] It should be noted that the conversion board in this embodiment is provided with two interfaces for accessing the password module, namely the first USB interface and Figure 2 The TF card interface in the TF card interface has no difference in functional operation from the password module connected through the first USB interface, and only the connection difference exists.

[0051] The connection difference is that the TF card interface is connected to a TF card slot, the password module is inserted into the TF card slot, and connected to the conversion board.

[0052] Furthermore, a second USB interface is provided on the conversion board, and the second USB interface is used to connect the biometric fingerprint recognition system to the terminal device via a USB connection cable.

[0053] The conversion board is also provided with a second USB interface, which is used to establish a connection between the biometric fingerprint recognition device and the terminal device. The second USB interface type is Type-A. By inserting a USB cable into the second USB interface and then inserting the other end of the USB cable into the terminal device, the biometric fingerprint recognition device can be deployed on the terminal device so that the recognition results generated by the recognition calculation module can be transmitted to the terminal device through the second USB interface.

[0054] At the same time, the terminal device can also be powered by the biometric fingerprint recognition device through the second USB interface.

[0055] Furthermore, the data conversion unit is equipped with a light guide, which is connected to a signal light on the conversion board. The light guide and signal light are connected to each other, and their primary function is to transmit light. When the conversion board detects a fault, the signal light on the conversion board illuminates. Through the light transmission from the light guide, the user can quickly identify the area or component with the fault.

[0056] Furthermore, an active buzzer is provided on the conversion board for issuing an audible alarm when the conversion board detects a fault, ensuring that the user's attention can be drawn by the audible alarm even if the visual alarm achieved by the light guide is ignored.

[0057] Furthermore, a computing board is provided in the identification computing unit, which is connected to the conversion board. The computing board adopts the Junzheng X1000E processor with a main frequency of up to 1.0GHz and built-in 64MB LPDDR, providing a 1-second ultra-fast startup capability.

[0058] It should be noted that the front of the biometric fingerprint recognition device (i.e. the side facing the user) is equipped with a fingerprint collector and a light guide column, the back of the biometric fingerprint recognition device (i.e. the side not facing the user) is equipped with a TF card interface and a second USB interface, and the right side of the biometric fingerprint recognition device is equipped with a first USB interface.

[0059] An embodiment of the present application further provides a biometric fingerprint recognition device, which includes the above-mentioned biometric fingerprint recognition system.

[0060] It can be understood that since the above-mentioned biometric fingerprint recognition system is used in the biometric fingerprint recognition device, the embodiments of the biometric fingerprint recognition device include all technical solutions of all embodiments of the above-mentioned biometric fingerprint recognition system, and the technical effects achieved are also exactly the same, which will not be repeated here.

[0061] The above description is only part of the embodiments of the present application and does not limit the patent scope of the present application. All equivalent structural transformations made by using the contents of the present application specification and drawings under the technical concept of the present application, or direct / indirect application in other related technical fields are included in the patent protection scope of the present application.
