[0038] Before executing the technical solution provided by the present invention, the application scenario can be described first. The technical solution provided by the embodiment of the present invention can be applied to any interface that requires user identity authentication. The technical solution provided by the embodiment of the present invention can be implemented by a verification sequence generation system for identity authentication. The verification sequence generation system for identity authentication is as follows: Figure 1 As shown. The system includes: a spatial coding unit, a high-frequency SSVEP coding unit and a time coding unit. Among them, the spatial coding unit is used to determine the functional area, the stimulation point position of the visual stimulation point, the number of stimuli, etc. The spatial coding unit includes three parts: a region divider, a stimulation position generator and a stimulation generator. The high-frequency Steady-State Visually Evoked Potentials (SSVEP) coding unit can be used to generate a stimulation frequency coding sequence corresponding to each visual stimulation point. The high-frequency SSVEP coding unit includes: a frequency selector and a frequency encoder. The time coding unit is used to receive the stimulation frequency coding sequence generated by the high-frequency SSVEP coding unit, and combine the stimulation interval duration to generate a stimulation sequence combined with time information. The time coding unit includes: a delay selector and a sequence generator. Based on this, the verification sequence generation process for identity authentication is realized through each unit in the system.

[0039] Example 1

[0040] Figure 2 This is a flow chart of a verification sequence generation method for identity authentication provided by the first embodiment of the present invention. This embodiment is applicable to the case where a user's identity is identified and authenticated by generating a verification sequence corresponding to a visual stimulus point. This method can be executed by a verification sequence generation device for identity authentication. The verification sequence generation device for identity authentication can be implemented in the form of hardware and / or software. The verification sequence generation device for identity authentication can be configured in electronic devices such as mobile phones, computers, or servers. Figure 2 As shown, the method includes:

[0041] S110 . Divide the system interface into multiple functional areas according to multiple business functions presented by the system interface, wherein the functional areas correspond to the business functions.

[0042] The system interface can be the interface currently requiring identity authentication. A business function can be understood as the business processing function corresponding to the system interface. A functional area can be a business area used to handle the corresponding business. That is, each functional area corresponds to a business function. For example, a trigger operation can be performed through business areas A, B, and C presented on the system interface to handle business within the corresponding business areas.

[0043] Specifically, since multiple business functions may be presented in the system interface, in order to avoid visual fatigue caused by the user only being able to look at a single position during subsequent identity authentication, the system interface can be divided into multiple functional areas through the area divider in the spatial coding unit according to the multiple business functions presented in the system interface, so as to determine multiple visual stimulation points based on the multiple functional areas, thereby improving the user experience during identity authentication.

[0044] For example, see Figure 3 , Figure 3 This is an example diagram for dividing the system interface. Figure 3 In the example, the system interface contains 6 business functions. The system interface can be divided into 6 functional areas according to the locations of these 6 business functions through the area divider.

[0045] S120 , determining multiple visual stimulation points based on multiple functional areas, and determining the critical flickering frequency and flickering order of the visual stimulation points based on the stimulation point positions, the number of stimulation points, and the critical flickering frequency range of the stimulation points.

[0046] Among them, the visual stimulation point can be a point used to flash to provide visual stimulation to the user being watched. The stimulation point position can be used to characterize the position information of the visual stimulation point. The number of stimulation points is the number of all visual stimulation points. The critical flashing frequency range of the stimulation point can be a preset stimulation frequency range of the steady-state visual evoked potential (SSVEP), that is, the flashing frequency range corresponding to the visual stimulation point. Optionally, the critical flashing frequency range of the stimulation point can be 30Hz to 50Hz. The critical flashing frequency can be understood as the flashing frequency corresponding to the visual stimulation point. The flashing order is the order in which multiple visual stimulation points flash.

[0047] Specifically, after determining the multiple functional areas of the system interface, the position information corresponding to each functional area can be determined. For example, if the functional area is a circular area, the stimulation point position can be represented by the center position coordinates and the boundary position coordinates of the circular area. If the functional area is a rectangular area, the stimulation point position can be represented by the center position coordinates, the four corner position coordinates, and the boundary position coordinates of the rectangular area. By analyzing the position information corresponding to the multiple functional areas based on the position generator in the spatial encoding unit, the multiple visual stimulation points corresponding to the system interface are determined. Based on the number of stimulation points, the critical flicker frequency of the corresponding number is determined from the critical flicker frequency range of the stimulation points through the high-frequency SSVEP encoding unit. Based on the stimulation point position of each visual stimulation point, the distance information between the visual stimulation points is determined. Based on the distance information, the critical flicker frequency of the corresponding stimulation point position is determined, that is, the critical flicker frequency corresponding to each visual stimulation point is determined. Accordingly, based on the distance information of each visual stimulation point, the flickering order of the visual stimulation points is determined based on the distance information.

[0048] In an embodiment of the present invention, a method for determining multiple visual stimulation points can be: based on a position generator in a spatial coding unit, the visual stimulation points are determined according to the position information of the intersection of the functional areas, wherein the functional areas are determined based on the segmentation of the area segmenter in the spatial coding unit.

[0049] The position generator can be a module for determining the location of a visual stimulus point. A functional area intersection can be understood as the point where two adjacent functional areas intersect. The location information of a functional area intersection can be represented by the intersection coordinates of the intersection. A region divider can be used to divide the system interface into multiple functional areas.

[0050] Specifically, the system interface is divided and processed according to the region segmenter in the spatial encoding unit to obtain multiple functional regions. The position information corresponding to each functional region is then determined. For multiple functional regions, the position information of the functional region intersection is determined based on the position information of the current functional region and the position information of the adjacent functional regions. The region segmenter sends the system interface after the functional region division and the position information of the functional region intersection to the position generator. The position generator determines the multiple visual stimulation points corresponding to the system interface based on the position information of the functional region intersection, on the basis of satisfying the preset stimulation point placement rules.

[0051] Optionally, the preset stimulation point placement rules include: visual stimulation points are determined from the intersection of functional areas; each functional area is separated by at least one visual stimulation point; and the number of visual stimulation points is less than the number of functional areas. It should be noted that if multiple visual stimulation point distributions satisfy the preset stimulation point placement rules, the distribution with the smallest number of visual stimulation points is used as the final visual stimulation point distribution. In other words, multiple visual stimulation points corresponding to the system interface are obtained.

[0052] For example, in conjunction with the above examples, see Figure 4 , Figure 4 Determine the sample image for the visual stimulus point, Figure 4 The basic point in is the visual stimulation point. Figure 3 After the six functional areas are selected, the center coordinates and boundary position coordinates of the six functional areas can be determined at the same time. Figure 3 After the system interface is divided into functional areas as shown in , multiple visual stimulation points are determined from the intersections of the functional areas, provided that the preset stimulation point placement rules are met. If there are multiple visual stimulation points that meet the preset stimulation point placement rules, then the situation with the smallest number of visual stimulation points is used as the final multiple visual stimulation points of the system interface based on the number of visual stimulation points in each situation. That is, Figure 4 Finally, two visual stimulation points were determined.

[0053] In an embodiment of the present invention, a method for determining a critical flicker frequency and a flickering order of a visual stimulation point may be: determining a plurality of available flicker frequencies consistent with the number of stimulation points based on the number of stimulation points and the range of the critical flicker frequencies of the stimulation points; taking any visual stimulation point as a stimulation starting point, assigning a target critical flicker frequency that satisfies a preset condition to the visual stimulation point corresponding to the stimulation starting point based on the plurality of available flicker frequencies, and updating the plurality of available flicker frequencies based on the target critical flicker frequency, wherein the updated available flicker frequencies do not include the target critical flicker frequency, and the preset condition is the maximum flicker frequency or the minimum flicker frequency among the available flicker frequencies; determining a target stimulation point corresponding to the stimulation starting point based on the stimulation point position of the stimulation starting point and the stimulation point positions of other visual stimulation points that are not assigned an available flicker frequency, determining a critical flicker frequency that satisfies the preset condition based on the updated available flicker frequency, and updating the plurality of available flicker frequencies based on the critical flicker frequency; continuing to use the target stimulation point as the stimulation starting point, and performing the steps of determining the target stimulation point and assigning the critical flicker frequency to the target stimulation point from the plurality of available flicker frequencies until all the encoded visual stimulation points are traversed; and determining the flickering order of the visual stimulation points based on the order in which the visual stimulation points serve as stimulation starting points.

[0054] Among them, the usable flicker frequency can be the flicker frequency of the stimulation point selected from the critical flicker frequency range of the stimulation point, which is consistent with the number of stimulation points. The stimulation starting point can be the visual stimulation point that first determines the critical flicker frequency. The preset condition can be the maximum flicker frequency or the minimum flicker frequency among the usable flicker frequencies. That is, the visual stimulation point corresponding to the stimulation starting point is assigned the maximum flicker frequency or the minimum flicker frequency as its corresponding target critical flicker frequency. The target critical flicker frequency can be the critical flicker frequency corresponding to the stimulation starting point. The critical flicker frequency is used to characterize the flicker frequency of the visual stimulation point. The updated usable flicker frequency can be understood as the remaining usable flicker frequency obtained after deleting the target critical flicker frequency from multiple usable flicker frequencies.

[0055] The other visual stimulation points that are not assigned with a flicker frequency can be understood as the visual stimulation points other than the visual stimulation point corresponding to the stimulation starting point. The target stimulation point is selected from the other visual stimulation points that are not assigned with a flicker frequency, and the visual stimulation point with the next critical flicker frequency is determined.

[0056] Specifically, after the high-frequency SSVEP encoding unit receives the visual stimulation points, the number of stimulation points, and the positions of the visual stimulation points transmitted by the spatial encoding unit, the frequency selector of the high-frequency SSVEP encoding unit selects, based on the number of stimulation points, a plurality of usable flicker frequencies from the critical flicker frequency range of the stimulation points, the number of frequencies of which is consistent with the number of stimulation points. It should be noted that to avoid interference between adjacent visual stimulation points, the frequency difference between adjacent usable flicker frequencies can be made as large as possible.

[0057] The visual stimulation point is encoded using the frequency encoder of the high-frequency SSVEP encoding unit. Specifically, for multiple visual stimulation points, any one visual stimulation point is used as the stimulation starting point. The maximum or minimum flicker frequency among multiple available flicker frequencies is determined, and this maximum or minimum flicker frequency is used as the target critical flicker frequency for the visual stimulation point corresponding to the stimulation starting point. The target critical flicker frequency is then removed from the multiple available flicker frequencies to obtain an updated available flicker frequency.

[0058] Based on the stimulation point position of the stimulation starting point and the stimulation point positions of other visual stimulation points not assigned an available flicker frequency, the visual stimulation point with the largest Euclidean distance from the stimulation starting point is determined, i.e., the target stimulation point. Furthermore, the critical flicker frequency of the target stimulation point that satisfies a preset condition is determined using the updated available flicker frequency. Specifically, if the target critical flicker frequency of the stimulation starting point is the minimum flicker frequency, then the critical flicker frequency of the target stimulation point is the available flicker frequency among the updated available flicker frequencies that is only higher than the minimum flicker frequency. The critical flicker frequency of the current target stimulation point is removed from the updated available flicker frequency. The current target stimulation point is used as the stimulation starting point, and the above steps of determining the target stimulation point and assigning the critical flicker frequency to the target stimulation point from the multiple available flicker frequencies are repeated until all visual stimulation points have been assigned available flicker points, i.e., all visual stimulation points have been encoded. The flickering order of the visual stimulation points is determined based on the order in which the critical flicker frequencies of the visual stimulation points are determined. This ensures that the critical flicker frequencies and flickering orders of the farthest visual stimulation points are closest. Accordingly, the critical flicker frequencies between visual stimulation points that are close to each other can be made more different, and the flickering orders can be disjointed. Based on this, not only can the user experience be improved, but also the accuracy of subsequent acquisition of the target user's brain wave signals can be improved.

[0059] For example, in conjunction with the above examples, see Figure 5 . Figure 5 This diagram shows an example of determining the critical flicker frequency for each visual stimulus point. The critical flicker frequency range for stimulus points is 30 Hz to 50 Hz. The frequency selector of the high-frequency SSVEP encoding unit selects two available flicker frequencies between 30 Hz and 50 Hz based on the number of stimulus points. The frequency encoder of the high-frequency SSVEP encoding unit then assigns these two available flicker frequencies to the corresponding visual stimulus points.

[0060] Figure 5 The frequency information in corresponds to the above-mentioned usable flicker frequency. The stimulation coordinates correspond to the above-mentioned stimulation point positions. The frequency information and stimulation coordinate information are received by a frequency encoder, and the critical flicker frequency corresponding to each time stimulation point is determined.

[0061] The critical flicker frequency corresponding to each temporal stimulation point can be determined by: for multiple visual stimulation points, starting with a particular visual stimulation point, selecting the minimum flicker frequency among the unassigned available flicker frequencies to encode the visual stimulation point; determining the Euclidean distance between the visual stimulation point and the other visual stimulation points; determining the visual stimulation point with the largest Euclidean distance from the visual stimulation point; and repeating the above process of using the visual stimulation point as the starting point and assigning available flicker frequencies to the starting point until the critical flicker frequencies of all visual stimulation points are determined.

[0062] Optionally, after obtaining the critical flicker frequency corresponding to each visual stimulation point, a stimulation frequency coding sequence corresponding to each visual stimulation point can be generated based on the critical flicker frequency of the visual stimulation point, that is, Figure 5 The stimulus grayscale sequence shown in .

[0063] Optionally, after obtaining the stimulus grayscale sequence, the stimulus point color of each visual stimulus point may be determined according to actual color modulation requirements.

[0064] Optionally, the flickering order of the visual stimulation points can be determined based on the order of the critical flickering frequencies used to determine the visual stimulation points. The flickering order can also be determined by the stimulation point positions of each visual stimulation point. Specifically, after the delay selector of the time encoding unit receives the stimulation grayscale sequences generated by the high-frequency SSVEP encoding unit, a certain visual stimulation point is selected as the first flickering visual stimulation point in combination with the positions of each stimulation point; the Euclidean distance between the first flickering visual stimulation point and other visual stimulation points is determined, and the visual stimulation point with the largest Euclidean distance from the first flickering visual stimulation point is selected as the second flickering visual stimulation point, and the above process is repeated to determine the flickering order of each visual stimulation point.

[0065] S130 , determining the stimulation interval duration between two adjacent visual stimulation points according to the stimulation point positions of the visual stimulation points.

[0066] The stimulation interval duration can be understood as the duration between two adjacent visual stimulation points flashing successively.

[0067] Specifically, based on the stimulation point position of each visual stimulation point and the critical flicker frequency of each visual stimulation point, the stimulation interval duration of two adjacent visual stimulation points is determined while ensuring that the difference in critical flicker frequencies of adjacent visual stimulation points is greater than a preset difference threshold.

[0068] In an embodiment of the present invention, a method for determining the stimulation interval duration of two adjacent visual stimulation points may be: determining the critical flicker frequency difference between the two adjacent visual stimulation points based on the stimulation point positions of multiple visual stimulation points; when the critical flicker frequency difference is less than a preset difference threshold, adjusting the stimulation interval duration of the two adjacent visual stimulation points; wherein the stimulation interval duration corresponds to time offset modulation of the delay.

[0069] The critical flicker frequency difference can be understood as the difference between the critical flicker frequencies of two adjacent visual stimulation points. The preset difference threshold can be a pre-set standard value for the difference in critical flicker frequencies between two adjacent visual stimulation points. Delayed time-shift modulation can be understood as determining the duration of the stimulation interval for each visual stimulation point, thereby determining the corresponding stimulation sequence based on the stimulation interval duration. This is equivalent to introducing time-shift information, i.e., performing time-shift adjustment on the visual stimulation points.

[0070] Specifically, based on the location of each visual stimulation point and the critical flicker frequency of each visual stimulation point, a critical flicker frequency difference between two adjacent visual stimulation points is determined. If the critical flicker frequency difference is less than a preset difference threshold, the interstimulus interval duration between the two adjacent visual stimulation points is adjusted to avoid visual fatigue caused by the interstimulus interval durations of adjacent visual stimulation points being too close, which could affect subsequent user authentication.

[0071] S140 , generating a stimulation sequence for each visual stimulation point according to the critical flickering frequency, flickering sequence, and stimulation interval duration of each visual stimulation point, so as to generate a verification sequence for identity authentication based on the stimulation sequence of each visual stimulation point.

[0072] The stimulation sequence can be used to characterize the presentation of visual stimulation points within the system interface. Specifically, the stimulation sequence can determine the critical flashing frequency, flashing sequence, and inter-stimulus duration of the corresponding visual stimulation points within the system interface. The verification sequence can be generated from the stimulation sequence of at least one visual stimulation point and used to verify identity.

[0073] Specifically, the critical flicker frequency, flicker sequence, and inter-stimulus duration of each visual stimulation point are encoded to determine a stimulation sequence for each visual stimulation point. A verification sequence for identity verification is generated based on the stimulation sequence of each visual stimulation point. Alternatively, based on actual needs, the stimulation sequence of the corresponding visual stimulation point is retrieved to generate a verification sequence based on the stimulation sequence of these visual stimulation points.

[0074] The technical solution of this embodiment divides the system interface into multiple functional areas based on the multiple business functions presented by the system interface. Multiple visual stimulation points are determined based on the multiple functional areas, ensuring the rationality of the stimulation point positions. Based on the stimulation point positions, number of stimulation points, and critical flicker frequency range of the stimulation points, a reasonable critical flicker frequency and flickering sequence of the visual stimulation points are determined, avoiding the poor user experience caused by constant flickering stimulation. Based on the stimulation point positions of the visual stimulation points, the stimulation interval duration between two adjacent visual stimulation points is determined. Based on the critical flicker frequency, flickering sequence, and stimulation interval duration of each visual stimulation point, a stimulation sequence is generated for each visual stimulation point, and a verification sequence for identity verification is generated based on the stimulation sequence of each visual stimulation point. The present invention generates corresponding visual stimulation points based on the business functions of the system interface and determines corresponding verification sequences based on various information about the visual stimulation points, enabling application in real-world business scenarios. This avoids the low security and poor flexibility of identity recognition based on features such as faces and fingerprints in existing technologies. By generating verification sequences corresponding to the visual stimulation points, user identity is identified and authenticated, improving the reliability and security of identity authentication.

[0075] Example 2

[0076] Figure 6 This is a flowchart of a verification sequence generation method for identity authentication provided by the second embodiment of the present invention. This embodiment of the present invention is a preferred embodiment of the above embodiment. Its specific implementation method can refer to the technical solution of this embodiment. Among them, the technical terms that are the same or corresponding to the above embodiment are not repeated here. Figure 6 As shown, the method includes:

[0077] S210 . Divide the system interface into multiple functional areas according to multiple business functions presented by the system interface, wherein the functional areas correspond to the business functions.

[0078] S220. Determine multiple visual stimulation points based on multiple functional areas, and determine the critical flicker frequency and flicker order of the visual stimulation points based on the stimulation point positions, the number of stimulation points, and the critical flicker frequency range of the stimulation points.

[0079] S230 , determining the stimulation interval duration between two adjacent visual stimulation points according to the stimulation point positions of the visual stimulation points.

[0080] S240 , generating a stimulation sequence for each visual stimulation point according to the critical flickering frequency, flickering sequence, and stimulation interval duration of each visual stimulation point.

[0081] S250: For multiple visual stimulation points, obtain access information of at least two business functions associated with the stimulation point positions of the visual stimulation points.

[0082] The at least two business functions associated with the stimulation point position may be business functions corresponding to the at least two functional areas associated with the visual stimulation point. Figure 4 The visual stimulation point on the left side of the image is associated with four functional areas, and the location of the stimulation point is associated with four business functions. Access information can be understood as the frequency of users accessing business functions.

[0083] Specifically, after determining the stimulation sequence of each visual stimulation point, the flashing duration of the corresponding visual stimulation point can also be determined based on the access information corresponding to at least two business functions associated with the stimulation point position of each visual stimulation point, so as to update the visual stimulation point according to the flashing duration.

[0084] S260: Determine the flickering duration of the visual stimulation point according to the access information, and update the stimulation sequence of the visual stimulation point based on the flickering duration.

[0085] The flashing duration can be used to represent the duration of each flash of the visual stimulation point.

[0086] Specifically, for multiple visual stimulation points, the average access frequency of the current visual stimulation point is determined based on access information of at least two business functions associated with the stimulation point location of the current visual stimulation point and information about the number of business functions. Based on the average access frequency of each visual stimulation point, the flickering duration of each visual stimulation point is determined. The stimulation sequence of the visual stimulation point is updated based on the flickering duration.

[0087] For example, refer to the above example. Figure 7 , Figure 7 This is an example diagram of the delay selector processing. Figure 7 The stimulus coordinates in correspond to the aforementioned stimulus point positions. The flicker duration t1 corresponds to the aforementioned flicker duration. The adjacent flicker interval t2 corresponds to the aforementioned stimulus interval duration.

[0088] After receiving the stimulus grayscale sequences and stimulus point locations generated by the high-frequency SSVEP encoding unit via the time encoding unit, the delay selector can be used to determine the access frequencies of at least two business functions associated with the stimulus point location of each visual stimulus point. Based on the access frequencies corresponding to each visual stimulus point and the number of business functions, the average access frequency corresponding to each visual stimulus point is determined. Based on the average access frequency of each visual stimulus point, the flashing duration t1 of each visual stimulus point is determined.

[0089] The flashing order of the visual stimulus points is determined according to the stimulus point position of each visual stimulus point through the delay selector of the time encoding unit.

[0090] The delay selector of the time encoding unit determines the adjacent flicker interval t2 of the visual stimulation point, that is, the stimulation interval duration, according to the stimulation point position of each visual stimulation point and the critical flicker frequency of each visual stimulation point.

[0091] See also Figure 8 , Figure 8 This is a processing example diagram of a sequence generator. After the delay selector based on the time coding unit determines the flickering duration t1, flickering order, and adjacent flickering interval t2 of the visual stimulation point, the flickering duration t1, flickering order, and adjacent flickering interval t2 of each visual stimulation point can be used as the stimulation time information of each visual stimulation point. Through the sequence generator, the stimulation grayscale sequence of each visual stimulation point is updated according to the stimulation time information of each visual stimulation point to obtain a stimulation grayscale sequence containing time information for each visual stimulation point, that is, a stimulation sequence. For example, the stimulation sequence generated by the delay selector and sequence generator of the time coding unit can be as follows Figure 9 shown. Figure 9 The flashing order corresponding to the stimulus sequence is stimulus 1-stimulus 4-stimulus 2-stimulus 3. Figure 9 Where t1 represents the flash duration corresponding to stimulus 1. t2 represents the interstimulus interval between two adjacent stimulus flashes, i.e., the interstimulus interval between stimulus 1 and stimulus 4, and the interstimulus interval between stimulus 4 and stimulus 2.

[0092] Optionally, an embodiment of the present invention further includes: for multiple visual stimulation points, determining the display size of the visual stimulation point according to the stimulation point position of the visual stimulation point and the center position information of multiple functional areas associated with the visual stimulation point, so as to update the stimulation sequence of the visual stimulation point based on the display size.

[0093] The center position information can be represented by the coordinate information corresponding to the center point of the functional area. The display size can be used to represent the size of the visual stimulation point. For example, if the visual stimulation point is circular, the display size can be understood as the circular area of ​​the visual stimulation point.

[0094] Specifically, for multiple visual stimulation points, the distance information between the current visual stimulation point and each functional area is determined based on the stimulation point position of the current visual stimulation point and the center position information of multiple functional areas associated with the current visual stimulation point. The average value of the distance information is determined based on the distance information and the number of functional areas associated with the current visual stimulation point. The display size of the current visual stimulation point is determined based on the average value of the distance information and a preset ratio between the average value of the distance information and the display size. The stimulation sequence of the visual stimulation point is updated based on the display size.

[0095] For example, in conjunction with the above examples, see Figure 10 , Figure 10 Figure 1 is an example of the processing of the stimulus generator. Figure 10 The stimulus coordinates in correspond to the updated stimulus point locations. The stimulus size corresponds to the display size mentioned above.

[0096] After the position generator of the spatial coding unit determines each visual stimulation point, the stimulus generator of the spatial coding unit can determine the distance information between the current visual stimulation point and each functional area based on the stimulation point position of the current visual stimulation point and the center position information of the four functional areas associated with the current visual stimulation point. Based on the distance information and the number of functional areas, the average value of the distance information is determined. Based on the ratio between the preset average value of the distance information and the stimulus size, the stimulus size corresponding to the average value of the distance information of the current visual stimulation point is determined. Accordingly, after the stimulus size of each visual stimulation point is determined, the stimulation point position of each visual stimulation point can be updated to ensure the positional accuracy of the visual stimulation point.

[0097] Optionally, the stimulus size of each visual stimulation point can be transmitted to the high-frequency SSVEP encoding unit and the time encoding unit to generate a stimulation sequence based on all stimulation information related to the visual stimulation point. Alternatively, after the stimulation sequence is generated, the stimulation sequence can be updated based on the stimulus size of the visual stimulation point. The stimulation information related to the visual stimulation point can include at least one of the following: a critical flicker frequency of the visual stimulation point, a flicker sequence, an interstimulus interval duration, a flicker duration, a stimulus size, a stimulation point location, and a stimulation point color.

[0098] S270. Generate a verification sequence for identity authentication based on the stimulation sequence of each visual stimulation point, so as to collect brain wave signals of the target user while the visual stimulation point flashes according to the verification sequence, and determine the identity authentication result based on the brain wave signals.

[0099] The EEG signal may be a EEG signal generated by a user gazing at a visual stimulation point when the visual stimulation point flashes according to the corresponding stimulation point position and stimulation sequence. The user gazing at the visual stimulation point is the target user. Optionally, the EEG signal may be collected by a corresponding EEG signal collector.

[0100] The authentication result may be a result obtained after authenticating the target user. For example, the authentication result may be that the target user's authentication has passed, or that the target user's authentication has failed.

[0101] Specifically, a verification sequence for user identity authentication is generated based on the stimulation sequence of each visual stimulation point. After detecting the target user's trigger operation for identity authentication, the visual stimulation point flashes according to the verification sequence at the corresponding stimulation point position in the system interface. The EEG signal collector acquires the target user's brainwave signal and sends the brainwave signal to the signal analyzer, which determines the target user's corresponding identity authentication result based on the signal analyzer.

[0102] Optionally, the method of generating a verification sequence for identity authentication based on the stimulation sequence of each visual stimulation point can be: based on the stimulation sequence of all visual stimulation points, controlling the corresponding visual stimulation points to flash on the target device to obtain a verification sequence for identity authentication; or, based on the current business, calling the associated visual stimulation points associated with the current business, and controlling the corresponding visual stimulation points to flash on the target device based on the stimulation sequence of the associated visual stimulation points to obtain a verification sequence for identity authentication.

[0103] The current service may be a service provided by a service function in the system interface. The associated visual stimulation point may be a visual stimulation point in the system interface associated with the current service. The target device may be an electronic device corresponding to the system interface. For example, the electronic device may be a mobile phone, computer, tablet, or other electronic device of the target user.

[0104] Specifically, based on the stimulation sequence of all visual stimulation points, all visual stimulation points are controlled to flash on the system interface of the target device to obtain a verification sequence for identity verification. Alternatively, based on the current service, associated visual stimulation points associated with the current service are retrieved, and based on the stimulation sequence of the associated visual stimulation points, corresponding visual stimulation points are controlled to flash on the system interface of the target device to obtain a verification sequence for identity verification. During the flashing of the visual stimulation points, the brain wave signals of the target user are obtained through the EEG signal collector.

[0105] The technical solution of this embodiment divides the system interface into multiple functional areas based on the multiple business functions presented in the system interface. Multiple visual stimulation points are determined based on the multiple functional areas, ensuring the rationality of the stimulation point positions. Based on the stimulation point positions, number of stimulation points, and critical flicker frequency range of the stimulation points, a reasonable critical flicker frequency and flickering sequence for the visual stimulation points are determined, avoiding the problem of poor user experience caused by constant flickering stimulation. Based on the stimulation point positions of the visual stimulation points, the stimulation interval duration between two adjacent visual stimulation points is determined. Based on the critical flicker frequency, flickering sequence, and stimulation interval duration of each visual stimulation point, a stimulation sequence is generated for each visual stimulation point. For each visual stimulation point, access information for at least two business functions associated with the stimulation point position is obtained. Based on the access information, the flickering duration of the visual stimulation point is determined, and the stimulation sequence for the visual stimulation point is updated based on the flickering duration. A verification sequence for identity authentication is generated based on the stimulation sequence of each visual stimulation point. As the visual stimulation point flickers according to the verification sequence, brainwave signals of the target user are collected, and the identity authentication result is determined based on the brainwave signals. The present invention generates corresponding visual stimulation points through the business functions of the system interface, and determines the corresponding verification sequence based on various information of the visual stimulation points, thereby realizing application in actual business scenarios. It avoids the problems of low security and poor flexibility in identity recognition based on features such as face and fingerprint in the existing technology. By generating a verification sequence corresponding to the visual stimulation point, the user identity is identified and authenticated, thereby improving the reliability and security of identity authentication.
