[0023] The infrared detection module 6 transmits data to the main chip 5 through electrical connection, the binocular liveness detection acquisition module 12, the palm print acquisition module 16, the vein acquisition module 17, the voice print acquisition module 10, and the fingerprint acquisition module 9 transmit data to the main chip 5 through electrical connection, and the binocular liveness detection acquisition module 12 exchanges information with the face acquisition module 15 through electrical connection;

[0024] When the infrared detection module 6 detects a person, the main chip 5 initiates the authentication process and activates the binocular liveness detection acquisition module 12, the palm print acquisition module 16, the vein acquisition module 17, the voice print acquisition module 10, the fingerprint acquisition module 9 and the face acquisition module 15 to work.

[0025] Furthermore, it also includes a keyboard 8, which transmits data with the password collection module 7 through electrical connection.

[0026] Furthermore, it also includes a microphone 11, which transmits data with the voiceprint collection module 10 through electrical connection.

[0027] Furthermore, it also includes an infrared camera 13 and an RGB camera 14, and both the infrared camera 13 and the RGB camera 14 are electrically connected to the face acquisition module 15 for data transmission.

[0028] Furthermore, the network interconnection module 4 includes a wireless base station and Ethernet.

[0029] Furthermore, the mobile terminal 1, the cloud management platform 2 and the main chip 5 are connected to the network using a protocol selected from MQTT and HTTP.

[0030] Furthermore, the multi-dimensional authentication module 3 synchronizes authentication information and logs to the cloud management platform 2 through the network interconnection module 4 .

[0031] Furthermore, the mobile terminal 1 includes mobile applications and web pages.

[0032] Furthermore, it also includes a fingerprint collector 18, which transmits data with the fingerprint collection module 9 through electrical connection.

[0033] The face acquisition module 15 uses the infrared camera 13 and the RGB camera 14 to acquire faces, the voiceprint acquisition module 10 uses the microphone 11 to acquire voiceprints, the password acquisition module 7 uses the keyboard 8 to acquire passwords, the fingerprint acquisition module 9 acquires fingerprints through the fingerprint acquisition device 18, and the main chip 5 performs feature comparison based on the acquired features and gives an authentication result.

[0034] The technical solution of the multi-dimensional authentication hardware module includes the integration of multiple biometric recognition technologies and dynamic password authentication functions to achieve a safer and more flexible authentication method. Since multi-dimensional authentication requires users to pass multiple authentication factors to complete authentication, even if one of the authentication factors is counterfeited or misused, the system still needs to use other authentication factors to confirm the user's identity, which greatly improves the security and accuracy of authentication.

[0035] Replacing the traditional single authentication factor method, the multi-dimensional authentication system is more difficult to attack or deceive, improves the security and accuracy of authentication, and covers a variety of biometric recognition technologies, including face recognition, fingerprint recognition, voiceprint recognition, and palmprint recognition, etc., comprehensively covering multiple parts of the user's body, improving the comprehensiveness and reliability of authentication, and can more comprehensively understand and confirm the user's identity, reducing omissions or errors in the authentication process.

[0036] Multiple biometric identification technologies: The module integrates multiple biometric identification technologies such as face recognition, voiceprint recognition, fingerprint recognition, palmprint recognition, etc. Each recognition technology has independent sensor and algorithm support to collect and analyze the corresponding biometric information.

[0037] Dynamic password authentication function: The module integrates dynamic password authentication function, which can generate and display dynamic passwords. The dynamic password generation algorithm can generate a set of 6-digit or 8-digit random numbers or other factors according to the scene requirements to ensure the security and uniqueness of the password.

[0038] Free combination of authentication factors: Users can freely select and combine authentication factors according to their needs, including face, voiceprint, fingerprint, palmprint and dynamic password. For example, users can enable face and fingerprint recognition for authentication at the same time, or choose to turn off voiceprint recognition or add iris recognition.

[0039] Flexible adjustment of authentication configuration: The module supports users to flexibly adjust authentication configuration. The number and weight of authentication factors can be adjusted according to application scenarios and security requirements. Users can control the priority and relationship of different authentication factors by setting authentication configuration parameters to meet the needs of different security levels.

[0040] Addition of other authentication factors: As an optional function, the module can also integrate other authentication factors; for example, users can choose to add iris recognition authentication factor to further improve the security and accuracy of authentication.

[0041] Comprehensive authentication factors: This patent combines multiple biometric recognition technologies with dynamic digital passwords to form a comprehensive authentication method. This is significantly different from the single authentication factor method in the prior art. In this patent, each authentication factor operates in parallel, and the user needs to verify multiple factors at the same time to complete the authentication, thereby improving the security and accuracy of the authentication.

[0042] Combining multiple biometric recognition technologies such as face recognition, fingerprint recognition, voiceprint recognition, dynamic digital password and palmprint recognition enables a safer and more accurate authentication process.

[0043] The authentication process is as follows:

[0044] 1. The user initiates an authentication request:

[0045] The user initiates an authentication request through an application or system interface.

[0046] 2. Start all authentication factors in parallel:

[0047] The camera starts collecting faces;

[0048] Dynamic password is activated, and 6-8 digits are displayed;

[0049] The microphone is activated to collect voiceprints;

[0050] The fingerprint collector starts to collect fingerprints;

[0051] 3. Feature comparison

[0052] The system processes all collected biometric data in parallel and compares them with pre-stored records.

[0053] The system obtains the recognition score of each authentication factor and obtains the comprehensive authentication result according to the weighted algorithm of the calculation formula.

[0054] 4. Feedback on certification results:

[0055] The system will feedback the authentication result to the user whether the authentication is successful or failed.

[0056] The authentication result calculation logic is as follows:

[0057] In the multi-dimensional authentication scheme, we can express the recognition result of each authentication factor with a numerical value, such as face recognition score, voiceprint recognition score, fingerprint recognition score, etc. At the same time, in order to take into account the importance of each authentication factor in the authentication process, we introduce a weight factor to measure the contribution of different authentication factors to the overall authentication.

[0058] Assume that we have n authentication factors, namely face recognition, voiceprint recognition, fingerprint recognition, etc., the corresponding recognition results are X1, X2, X3, etc., the weights are Q1, Q2, Q3, etc., and the overall authentication result is . The weighted formula can be expressed as:

[0059] Overall certification result = X1×Q1+X2×Q2+...+Xn×Qn

[0060] Among them, Q1, Q2, ..., Qn are weights of each authentication factor, Q1+Q2+Qn=1. X1, X2, ..., Xn are recognition result scores of each authentication factor, and the total score is the voiceprint collection module 100.

[0061] If face recognition score*face weight+voiceprint recognition score*voiceprint weight+fingerprint recognition score*fingerprint weight+palm vein recognition score*palm vein weight>95, it can be judged as passed authentication, and the overall authentication result score and the weights of authentication factors can be flexibly adjusted and freely configured according to changes in the environment. For example, face recognition can be used as the method with the greatest weight, and as long as the face fails, the overall authentication is judged as failed.

[0062] Get a more comprehensive and accurate overall authentication result, and flexibly adjust the weights of various authentication factors according to actual needs and environmental changes to adapt to different application scenarios and security needs.

[0063] A dynamic digital password is a dynamic factor, and other dynamic factors can also be considered as alternatives, such as dynamic facial expression recognition, dynamic gesture recognition, etc. These alternatives to dynamic factors can also enhance the security and accuracy of the system.

[0064] The working principle and use process of the present invention are as follows: the face acquisition module 15 uses the infrared camera 13 and the RGB camera 14 to acquire faces, the voiceprint acquisition module 10 uses the microphone 11 to acquire voiceprints, the password acquisition module 7 uses the keyboard 8 to acquire passwords, the fingerprint acquisition module 9 uses the fingerprint acquisition device 18 to acquire fingerprints, the main chip 5 performs feature comparison based on the acquired features, and gives the authentication result. The technical solution of the multi-dimensional authentication hardware module includes integrating multiple biometric feature recognition technologies and dynamic password authentication functions to achieve a safer and more flexible authentication method. Since the multi-dimensional authentication requires the user to pass multiple authentication factors, the authentication result is obtained by comparing the features of the acquired features with the dynamic password authentication function. Therefore, even if one of the authentication factors is forged or misused, the system still needs to use other authentication factors to confirm the user's identity, which greatly improves the security and accuracy of authentication. It replaces the traditional single authentication factor method. The multi-dimensional authentication system is more difficult to attack or deceive, improves the security and accuracy of authentication, covers a variety of biometric recognition technologies, including face recognition, fingerprint recognition, voiceprint recognition and palmprint recognition, etc., comprehensively covers multiple parts of the user's body, improves the comprehensiveness and reliability of authentication, can more comprehensively understand and confirm the user's identity, and reduce omissions or errors in the authentication process.

Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
