[0031] In the following, only some exemplary embodiments are simply described. As those skilled in the art can recognize, the described embodiments can be modified in various different ways without departing from the spirit or scope of the present invention. Therefore, the drawings and the description are considered to be exemplary in nature and not restrictive.

[0032] Embodiment 1

[0033] In modern biometric technologies, iris recognition is widely used in authentication due to its high uniqueness and non-forgeability. Usually, a module with iris acquisition function can be activated and perform iris acquisition after being connected to a computer, thus achieving efficient and secure authentication. However, there are some challenges and inconveniences in practical applications.

[0034] Specifically, when a user connects a plug-in with iris acquisition function (such as a USB key or a dedicated iris scanning device) to a computer, it is difficult to aim at the user's eyes for shooting due to the poor connection position of the plug-in or the inability of the iris acquisition module to rotate and adjust the angle. This limitation in design makes it necessary for the user to laboriously adjust their posture or the position of the device during use to ensure that the iris acquisition module can correctly capture a clear iris image. This not only increases the operation difficulty for the user but also may affect the accuracy and efficiency of iris recognition, especially in situations with unfavorable lighting conditions or when the user wears glasses.

[0035] To overcome these inconveniences and improve the user experience and system usability, it is necessary to improve the existing iris acquisition module and its installation method. Currently, the improvement is to structurally improve the iris acquisition module to add an adjustable angle function, but this improvement method requires a redesign of the hardware structure and incurs a relatively high improvement cost.

[0036] To solve the above problems, this embodiment provides an iris key plug-in, which is connected to a target device by the method of shooting first and then connecting, improving the user experience and iris recognition efficiency.

[0037] As Figure 1 shown, the iris key plug-in mainly includes an iris acquisition module, a data processing module, a storage module, and an interface module, and signal intercommunication is achieved between the modules through circuits.

[0038] It should be explained that the iris key plug-in refers to a hardware device integrated with iris recognition function and equipped with a USB interface or other standard interfaces, which can be directly connected to a computer or other devices. For example, the iris key plug-in can be a USB security key integrated with an iris acquisition module, suitable for scenarios requiring high-security authentication, such as financial transactions, enterprise internal network access, etc.; the iris key plug-in can also be a mobile device, such as a smart phone, a tablet computer, a smart watch, etc., which uses the built-in camera of the mobile device for iris recognition and generates and manages keys through a dedicated application; the iris key plug-in can also be an external docking station or expansion module, which realizes the iris recognition function through the external docking station or expansion module and is suitable for the upgrade of existing devices.

[0039] In this embodiment, the iris acquisition module in the iris key plugin is used to acquire iris data. For this purpose, the iris acquisition module needs to be equipped with a high-resolution sensor, that is, a camera with a high resolution (at least over 5 million pixels), to capture clear and detailed iris images, and perform denoising and contrast enhancement processing on the iris images to ensure that the image quality reaches the best state.

[0040] Furthermore, the iris acquisition module can also be equipped with an autofocus system and an optical zoom function. The autofocus system is used to ensure that the camera can quickly and accurately focus on the user's eyes to obtain clear iris images; the optical zoom function can adjust the focal length at different distances to adapt to different usage scenarios and user positions. Even the iris acquisition module can use binocular or multi-camera to capture iris images from different perspectives to generate depth information, which is convenient for subsequent construction of a three-dimensional model.

[0041] It should be noted that the iris data acquired by the iris acquisition module in this embodiment includes but is not limited to iris images, depth information, etc., which is convenient for subsequent processing by the data processing module.

[0042] Furthermore, the iris key plugin is also equipped with a live detection module. The input end of the live detection module is connected to the iris acquisition module, and its output end is connected to the data processing module. The live detection module is used to detect the live state of the iris data acquired by the iris acquisition module. Only when the live state detection is passed, a passing message is fed back to the data processing module. The data processing module only generates corresponding data packets according to the iris data after receiving the passing message fed back by the live detection module. Among them, the live state detection can generate a depth map through stereo vision or a depth sensor to judge whether the iris has a real three-dimensional structure. If there is a real three-dimensional structure, it is determined that the iris is in a live state. If the three-dimensional structure cannot be constructed, it is considered that the iris data is forged.

[0043] In this embodiment, the data processing module generates corresponding data packets according to the iris data, where the data packet is a driver packet containing iris feature information generated according to the iris data.

[0044] Specifically, texture features such as spots, stripes, and crypts are extracted from the iris data, color features such as pigment spots in the iris and their distribution patterns are extracted, and even a three-dimensional model of the iris is generated using stereo vision or a depth sensor to extract its structural features.

[0045] After determining the iris feature information (texture feature, color feature, structural feature), a strong encryption algorithm (such as AES) is used to encrypt the extracted iris features to ensure data security, and a digital signature is used for the encrypted iris feature information with a private key to ensure the legality and integrity of the data source.

[0046] Obtain multiple different versions of driver programs suitable for different operating systems and hardware platforms, write detailed metadata information for each driver program to generate a set of driver programs. In this embodiment, the encrypted iris feature information and the set of driver programs are packaged into a data packet and digitally signed.

[0047] In this embodiment, the data packet structure includes metadata, iris feature data, and a set of driver programs. The metadata includes the supported operating system version, hardware compatibility information, driver program version number, release date, etc.; the iris feature data includes the encrypted iris feature information, such as texture features, color features, and three-dimensional structure features, etc.; the set of driver programs contains multiple different versions of driver programs suitable for different operating systems and hardware platforms.

[0048] Furthermore, the data processing module can also construct a corresponding iris model for the collected iris data. This iris model is a three-dimensional model. Besides being used to determine whether the iris has a real three-dimensional structure, it can also generate multiple data packets according to the iris model; after the iris key plugin accesses the target device, authentication is performed through multiple data packets to improve the security of authentication.

[0049] Among them, the method for generating multiple data packets according to the iris model is as follows:

[0050] After constructing the iris model, randomly select several local regions from the iris model through a random algorithm, and identify the feature information (such as texture features, color features, three-dimensional structure features, etc.) of each selected local region, and package the feature information of the randomly selected local regions into multiple data packets. Each data packet contains the feature information of one or more local regions. The number of randomly selected local regions can be preset, and the local region features included in the data packet can also be preset. Authentication is performed through multiple data packets to improve the security and robustness of authentication.

[0051] The iris key plugin accesses the target device through its interface module. The target device can be a computer, a mobile phone, a tablet, etc. When the target device automatically detects the presence of new hardware, it will obtain the data packet of the iris key plugin, parse the data packet for authentication and start the pre-configured driver installation program. Among them, for the plug design of the interface module, a universal interface can be used, such as widely used interface standards, such as USB Type-C or USB-A, etc.; or an interface that supports plugging in both directions (such as USB Type-C) can be used to reduce the user's insertion direction error; a magnetic interface (such as MagSafe) can also be used, which is convenient for quick alignment and insertion, and at the same time avoids damage caused by accidental pulling out.

[0052] In some embodiments, the interface module can also be connected to the target device via a wireless connection. That is, the interface module can be a Bluetooth or Wi-Fi module, providing Bluetooth or Wi-Fi connection options, reducing the limitations of physical connections and facilitating switching between different devices for use.

[0053] Meanwhile, an indicator light can also be provided on the iris key plugin to display the device status (such as power, connection status, verification result, etc.) through the indicator light, helping the user understand the progress of the current operation.

[0054] The iris key plugin also has a storage module. The storage module can be built into the iris key plugin or connected to the storage module in the cloud through a wireless network to achieve the effect of data packet storage. In this embodiment, the iris key plugin has a built-in storage module. The storage module stores data packets within a limited time, that is, the storage module only stores the generated data packets within a certain time. When the storage duration exceeds the set value, the storage module will automatically clear the data packets.

[0055] When the storage module of the iris key plugin stores data packets, the iris key plugin can transfer the data packets stored in the storage module to the connected device for identity verification only when it is connected to the target device. If the storage module has cleared the data packets, even if the iris key plugin is connected to the target device, no identity verification program or driver installation process will be started.

[0056] The status of whether there are data packets in the storage module can also be prompted through the corresponding indicator light, allowing the user to access the target device for identity verification and driver installation within the time when the data packets still remain in the storage module after collecting iris data.

[0057] The working principle of the iris key plugin in this embodiment is as follows:

[0058] Before the iris key plugin is connected to any target device, it pre-collects the user's iris data through the iris collection module on the iris key plugin, and generates one or more data packets according to the iris data through its built-in data processing module, and stores them in the storage module of the iris key plugin within a limited time. The user can connect the interface module of the iris key plugin to any target device within the limited time. After connection, the target device obtains all the data packets stored in the iris key plugin. After parsing all the data packets, the iris feature information and the driver program set contained in the data packets can be obtained. The iris feature information obtained by parsing is compared with the pre-stored iris template in the target device for verification. If the iris feature information matches the iris template, the identity verification is considered successful. If the iris feature information does not match the iris template, the identity verification is considered failed.

[0059] When the authentication is successful, the target device obtains its own system information, finds the driver that matches its own system information from the driver set, and installs the driver so that the target device can obtain the access permission to the iris key plugin. For example, it can obtain the resource access permission of the iris key plugin (such as devices like USB or smartphones) for data access. If the authentication fails, an alarm prompt is given by the target device or the iris key plugin. At this time, the corresponding driver cannot be installed, so the corresponding access permission cannot be obtained.

[0060] Embodiment 2

[0061] This embodiment provides an authentication method based on an iris key plugin, and its execution object is a target device connected to the iris key plugin. The target device can be a server, a smartphone, a computer tablet, etc.

[0062] It should be noted that the structure of the iris key plugin connected to the target device and the way it generates data packets have been described in Embodiment 1 and will not be elaborated here.

[0063] As Figure 2 shown, the authentication method based on the iris key plugin specifically includes the following steps:

[0064] Step S1: When it is detected that the iris key plugin is connected, obtain the data packet transmitted by the iris key plugin; the data packet is a driver package containing iris feature information that the iris key plugin pre-collects iris data before connection and generates according to the iris data.

[0065] After the iris key plugin is connected to the target device, a secure communication channel is established between the iris key plugin and the target device. Usually, an encryption protocol (such as TLS / SSL) is used to ensure the security of data transmission. When establishing a secure connection, the two parties exchange encryption keys for subsequent data encryption and decryption. During this period, all data transmitted from the plugin to the computer is encrypted to prevent man-in-the-middle attacks or data leakage.

[0066] Step S2: Analyze the data packet to obtain the iris feature information and the corresponding driver, use the iris feature information for authentication, and install the driver to obtain the access permission to the iris key plugin when the authentication is passed.

[0067] When the target device receives a data packet generated by the iris key plugin, it decrypts the encrypted data packet using the corresponding decryption key, and extracts the feature information of the local area from the decrypted data packet. The feature information is compared with the iris template pre-stored in the target device. The comparison content can be one or a combination of texture matching (comparing texture features such as speckle density and stripe direction), color matching (comparing color distribution patterns), and three-dimensional structure matching (comparing three-dimensional features such as height changes in depth maps). If the feature matching is successful, the authentication is considered passed.

[0068] When the target device receives multiple data packets generated by the iris key plugin, during the authentication process, multiple data packets are used for matching in sequence. If a specified number of data packets match successfully, the authentication is considered passed. Assume that the iris key plugin generates three data packets, and the target device sequentially performs iris template comparison on the three data packets. If the number of successfully matched data packets exceeds the matching threshold, the authentication can be considered passed. To improve security, the matching threshold for multiple data packets can be set (for example, at least 2 data packets match successfully). If the matching threshold is not met, the system prompts the user to re-perform iris collection and verification, and gives the reason for the error (such as poor image quality, feature mismatch, etc.).

[0069] It should be noted that the iris template is the iris data of legitimate users pre-stored in the target device. The iris data is relatively complete, clear, and standard. The standard iris data is used as the iris template, and it is compared with the iris features collected by the iris key plugin to achieve the purpose of authentication. The iris template can be obtained through pre-collection or network transmission, and the user's iris template can be downloaded to the target device for storage after Internet authorization and authentication.

[0070] In this embodiment, the iris key plugin that has already collected iris data is inserted into the target device in the way of shooting first and then connecting, so that the target device can perform authentication and drive installation through the iris feature information in the iris key plugin, replacing the original traditional plugin usage method of connecting first and then shooting, which can reduce the user operation difficulty and improve the usage efficiency.
