[0040] The following will be described with reference to the accompanying drawings:

[0041] Refer to the attached Figure 1 , which shows a schematic structural diagram of a data interaction system provided by an embodiment of the present application. As Figure 1 shown, it includes: a mouse 100 and a host computer 200. Among them, the mouse 100 includes a finger vein recognition circuit 110 or a fingerprint recognition circuit 110, a key circuit 120, a mouse module circuit 130, a control circuit 140, and an image acquisition device 150. Among them, the finger vein recognition circuit 110 or the fingerprint recognition circuit 110 is configured to generate finger vein verification information or fingerprint verification information based on the user's finger vein image or fingerprint image; the key circuit 120 is connected to the finger vein recognition circuit 110 or the fingerprint recognition circuit 110 and is configured to extract key information based on the finger vein verification information or the fingerprint verification information and send the key information to the host computer 200 for access; the mouse module circuit 130 is configured to implement the button operation and navigation operation of the mouse 100; the control circuit 140 is respectively connected to the mouse module circuit 130 and the key circuit 120 and is used to enable the mouse module circuit 130 and the key circuit 120 to be independently recognized; the image acquisition device 150 is connected to the finger vein recognition circuit 110 or the fingerprint recognition circuit 110 and is configured to acquire the user's finger vein image or fingerprint image.

[0042] After the mouse 100 is successfully connected to the host computer 200, the user can select to obtain the key information through finger vein verification or fingerprint verification according to the requirements. For example, when the user uses the finger vein verification method, the finger vein recognition circuit 110 obtains the user's finger vein image and generates corresponding finger vein verification information according to the user's finger vein image. The control circuit 140 manages the connection interface between the mouse 100 and the host computer 200, so that the host computer 200 can simultaneously recognize the mouse module circuit 130 and the key circuit 120. Therefore, when the finger vein verification information shows that the user's finger vein image is consistent with the pre-stored finger vein image, the key circuit 120 sends the stored key information to the host computer 200 for login according to the finger vein verification information, so as to realize system access or data access on the host computer 200.

[0043] Similarly, when the user uses the fingerprint verification method, the fingerprint recognition circuit 110 obtains the user's fingerprint image and generates corresponding fingerprint verification information according to the user's fingerprint image. When the fingerprint verification information shows that the user's fingerprint image is consistent with the pre-stored fingerprint image, the key circuit 120 sends the stored key information to the host computer 200 for login according to the fingerprint verification information, so as to realize system access or data access on the host computer 200.

[0044] In the embodiment of the present application, by integrating the key circuit and the mouse module circuit in the mouse, when the host computer has only one interface, the mouse and the USB key can be simultaneously connected to the host computer. Further, the user can select the finger vein or fingerprint recognition method according to personal preference to obtain the key information. Whether through the finger vein recognition circuit or the fingerprint recognition circuit, the mouse can accurately capture the user's biometric image and generate corresponding finger vein verification information and fingerprint verification information. The key circuit securely transmits the encrypted key information to the host computer according to the finger vein verification information and the fingerprint verification information to realize fast login, so as to access the system or data. It avoids the risk of password leakage caused by the user entering the password during secure login, and improves the security and flexibility of access.

[0046] The image acquisition device can be integrated on the mouse and connected to the finger vein recognition chip U7, and is used to acquire the finger vein image or fingerprint image of the user. Among them, when acquiring the finger vein image of the user, it is necessary to cooperate with the near-infrared array lamp group, image sensor and optical lens in the image acquisition device. That is, the near-infrared array lamp group provides illumination to make the finger veins of the user more obvious. The optical lens images the illuminated finger veins of the user onto the image sensor. The image sensor sends the captured finger vein image of the user to the finger vein recognition chip U7 for processing. The finger vein recognition chip U7 performs multiple processing processes such as image enhancement, filtering, normalization, binarization and feature extraction on the finger vein image of the user, so as to generate finger vein verification information. And when the finger vein verification information shows that the finger vein image of the user is consistent with the pre-stored finger vein image, the key circuit sends the stored key information to the host computer for access according to the finger vein verification information.

[0049] When the user performs fingerprint verification, it is necessary to collect the fingerprint image of the user through the fingerprint sensor in the image acquisition device and send the fingerprint image to the fingerprint recognition chip U6 for processing. The fingerprint recognition chip U6 performs multiple processing processes such as grayscale processing, normalization processing, image segmentation, binarization, image enhancement and thinning processing on the fingerprint image of the user, so as to generate fingerprint verification information. When the fingerprint verification information shows that the fingerprint image of the user is consistent with the pre-stored fingerprint image, the key circuit sends the stored key information to the host computer for access according to the fingerprint verification information. Further, the first capacitor C9 is respectively connected to the pin 3V3 of the fingerprint recognition chip U6 and the first external power supply 3V3, and is used to remove high-frequency noise on the power line to ensure a stable power supply for the fingerprint recognition chip U6 or other circuit components.

When the user performs finger vein verification or fingerprint verification, the security chip U5 extracts the pre-stored key information according to the finger vein verification information and the fingerprint verification information sent by the finger vein recognition chip or the fingerprint recognition chip, and sends the key information to the host computer for access.

[0053] The input terminal VIN of the low-voltage dropout linear regulator U4 is connected to an external power supply, and the output terminal VOUT of the low-voltage dropout linear regulator U4 is respectively connected to the pin VDD33 and the pin VCC of the security chip U5.

The crystal oscillator Y1 is respectively connected to the first clock source input pin EXTAL and the second clock source input pin XTAL of the security chip U5, and is used to provide a stable clock signal for the security chip U5.

During the process that the image acquisition device acquires the finger vein image or fingerprint image of the user, and the finger vein recognition chip and fingerprint recognition chip respectively process the finger vein image or fingerprint image to generate corresponding verification information, the first light-emitting diode LED_B flashes blue light, and the second light-emitting diode LED_R and the third light-emitting diode LED_G do not emit light, indicating that the security chip U5 is waiting for finger vein verification information or fingerprint verification information.

[0057] When the second light-emitting diode LED_R flashes red light, while the first light-emitting diode LED_B and the third light-emitting diode LED_G do not emit light, it indicates that the security chip U5 has received the finger vein verification information or fingerprint verification information, and is extracting the pre-stored key information according to this information.
