[0029] Embodiment 1
[0030] Figure 1 1 is a flowchart of a login verification method provided by the first embodiment of the present invention; this embodiment can be applied to the situation where the business system of a bank authenticates the target user according to the character information input by the user in combination with the historical structure, and is specifically applicable to the situation where the user logs in to the mobile banking or the bank staff logs in to the work system and needs to perform login verification. The method can be executed by a login verification device, which can be implemented in the form of hardware and / or software, and the login verification device can be configured in an electronic device, such as a business system of a bank, such as Figure 1 As shown, the login verification method includes:
[0031] S101 . In response to a login request of a target user, instruct the target user to start inputting characters through a preset input device, and monitor the input process to obtain input character information.
[0032] The target user refers to a user who sends a login request to the business system. The target user can be a customer who handles business through the business system, or a bank staff member who logs into the work system. The login request can be a login request sent by the target user to the business system through the mobile banking client, or a login request sent by a bank staff member to the work system. The preset input device can be at least one of the following: a mouse, an electronic pen, and a screen sensor.
[0033] The input process may be a process in which the target user inputs characters through a mouse, or a process in which the target user inputs characters on a screen sensor through an electronic pen and a finger. The input character information may represent attribute information of the input character, such as the total number of strokes of the input character, stroke feature points, global position features, relative front point features, and transition zone features. It should be noted that one input process in the present invention may correspond to one character input by the target user.
[0034] Optionally, instructing the target user to start inputting characters through a preset input device, including: if the preset input device is a mouse, instructing the target user to input characters by pressing the left mouse button, sliding the mouse, and lifting the left mouse button; if the preset input device is an electronic pen and a screen sensor, instructing the target user to input characters by controlling the electronic pen to touch the screen and slide on the screen sensor.
[0035] The screen sensor may be, for example, an interface screen of a business system client, and may sense the sliding track of an electronic pen or a finger on the screen.
[0036] Optionally, if the preset input device is a mouse, the target user can be instructed to start by pressing the left mouse button, writing by sliding the mouse, and finally completing the input of one stroke of the character by lifting the left mouse button. Until it is detected that the typing completion condition is met, the target user is considered to have completed the character input, and the input character information corresponding to the input process can be confirmed, where the typing completion condition can be that the number of input strokes reaches a preset stroke threshold or the pressing operation is not performed within a preset time after the left mouse button is lifted.
[0037] It should be noted that the above embodiments of the present invention can enrich the target user's character inputting methods and accordingly accurately identify the character information inputted by the user by instructing the user to input characters through different operations when the input devices are of different types.
[0038] Optionally, the input process is monitored to obtain input character information, including: determining the sub-input process of each character stroke in the input process according to the device type of a preset input device, and determining the stroke feature points corresponding to each character stroke according to the sub-input process; determining the target feature points from the stroke feature points, and determining the global position feature, relative front point feature and transition zone feature corresponding to the target feature points; determining the input character information according to the total number of strokes, stroke feature points, global position feature, relative front point feature and transition zone feature.
[0039] Among them, one input process corresponds to the input process of one character, and one sub-input process corresponds to the input process corresponding to one character stroke contained in the character. The total number of strokes corresponds to the number of strokes contained in the input character of one input process, and the total number of strokes is the same as the number of sub-input processes. The stroke feature point refers to the feature point position recorded in the process of inputting the stroke.
[0040] The stroke feature points represent the positions of the mouse or electronic pen at different recording times in each sub-input process. The target feature points refer to a preset number of feature points extracted from the stroke feature points. The global position feature represents the position information of the target feature points on the input screen. The relative previous point feature represents the relative position of each target feature point relative to the previously recorded target feature point. The transition zone feature refers to the feature of deviating the target feature points in groups of three.
[0041] Optionally, the stroke feature points corresponding to each character stroke can be determined based on the position information of the mouse or electronic pen recorded during the sub-input process. Furthermore, the total number of strokes, stroke feature points, global position features, relative previous point features and transition zone features corresponding to each input process can be combined to generate input character information corresponding to the input character of the input process.
[0042] It should be noted that the above-mentioned embodiment of the present invention monitors the sub-input process of each character stroke, determines the stroke feature points, and determines the input character information in combination with the total number of strokes, global position features, relative previous point features and transition zone features. It can refine the input process of the target user, thereby determining accurate and comprehensive input character information, which helps to ensure the effectiveness of subsequent identity verification.
[0043] Optionally, target feature points are determined from the stroke feature points, and the global position features, relative front point features and transition zone features corresponding to the target feature points are determined, including: determining a preset number of target feature points from the stroke feature points based on the recording time of the stroke feature points, and determining the global position features and relative front point features of the target feature points; determining the transition zone features based on the global position features of the target feature points and based on preset calculation rules.
[0044] The preset number may be, for example, 8. The recording time refers to the time for recording each stroke feature point in the sub-input process of the corresponding stroke.
[0045] Optionally, the writing order of each stroke feature point can be determined according to the recording time of the stroke feature points, and a preset number of stroke feature points can be divided into equal parts according to the writing order, such as 8 equal parts, and one of the stroke feature points in each equal part can be determined as the target feature point, so as to determine a preset number of target feature points from the stroke feature points.
[0046] Optionally, the position information of the target feature point can be determined as a global position feature, and the relative position between each target feature point and the previously recorded target feature point can be determined as a relative front point feature. For example, if the global coordinates of point A are (1,1) and B (2,3), the relative front point feature of B relative to A can be represented by the coordinates (1,2).
[0047] Optionally, after determining the target feature points, a transition zone feature can be calculated for every three target feature points as a group. For example, if the number of target feature points is 5, three transition zone features can be determined. Recording the transition zone features can help reduce recognition bias during subsequent verification.
[0048] For example, if the global position features of the three target feature points are (x1, y1), (x2, y2) and (x3, y3), the transition zone feature s can be determined by the following calculation rule:
[0049] s=(x1*y2+x2*y3+x3*y1-x1*y3-x2*y1-x3*y2) / are
[0050] Among them, are=abs(x1-x3), abs() represents the absolute value function.
[0051] It should be noted that the above-mentioned embodiment of the present invention obtains target feature points by screening stroke feature points according to the recording time to calculate global position features, relative front point features and transition zone features. Representative target feature points can be screened out from the stroke feature points, thereby obtaining global position features, relative front point features and transition zone features that can accurately express the stroke features.
[0052] Optionally, based on the device type of a preset input device, the sub-input process of each character stroke in the input process is determined, including: if the device type of the preset input device is a mouse, the input process corresponding to the pressing of the left mouse button and the lifting of the left button is determined as the sub-input process of each character stroke; when it is detected that the number of input strokes reaches a preset stroke number threshold or no pressing operation is performed within a preset time after the left mouse button is lifted, the input process is determined to be ended.
[0053] The preset stroke number threshold may be, for example, 15 strokes, and the input process may include at least one sub-input process.
[0054] Exemplarily, timing starts when it is detected that the target user presses the left mouse button, and recording can be performed at fixed time intervals. Specifically, when the recording time point is reached, a point can be randomly selected within a certain range around the current mouse coordinates and the coordinates of the point can be recorded as a stroke feature point. When it is detected that the target user lifts the left mouse button, the timing ends, and this process is regarded as a sub-input process of a stroke.
[0055] Optionally, during a stroke sub-input process, if it is detected that the number of recorded stroke feature points exceeds a preset maximum number, the feature point recording of the sub-process may be terminated, wherein the preset maximum number may be, for example, 300 points.
[0056] It should be noted that the above-mentioned embodiment of the present invention obtains the sub-input process by monitoring the pressing, sliding and lifting states of the left mouse button when the input device is a mouse, and detects whether the input is completed based on the monitoring of the number of strokes and the length of time after lifting. It can accurately identify the sub-input process of each stroke and promptly detect the end of the input process, thereby improving the efficiency of the entire identity authentication process.
[0057] S102: Determine a history structure corresponding to the target user's historical input characters from a preset font library, and determine a target structure corresponding to the input character information.
[0058] Among them, the preset font library can store historical structures corresponding to historical input character information of different management customers, and can also store historical characters corresponding to each historical structure. Each management user can store at least one corresponding historical structure, and the historical structure is a structural storage form obtained by combining and splicing historical character information. Management customers include target customers. The target structure is a structure obtained by combining and splicing input character information. The target structure can record the total number of strokes, stroke feature points, global position features, relative front point features, and transition zone features.
[0059] Optionally, a match may be performed in a preset font library according to the identity of the target user to determine a history structure corresponding to the historical input characters of the target user.
[0060] Optionally, the total number of strokes, stroke feature points, global position features, relative front point features and transition zone features may be combined according to a preset sequence and structure format to determine a target structure of input character information corresponding to each input character.
[0061] S103: Compare the history structure with the target structure, and determine whether the identity authentication of the target user is passed according to the comparison result, so as to respond to the login request.
[0062] The comparison result may be a consistency comparison result of each input character information in the history structure and the target structure.
[0063] Optionally, if the identity authentication of the target user is passed, the target user may be allowed to log into the system; if not, the target user may be denied to log into the system, thereby implementing a response to the login request.
[0064] Optionally, the target structure may be compared with each historical structure respectively. If the comparison result between any historical structure and the target structure is passed, it can be determined that the identity authentication of the target user is passed.
[0065] Optionally, the historical structure and the target structure are compared, and based on the comparison result, it is determined whether the identity authentication of the target user is passed, including: determining the final comparison result based on the comparison result of at least one of the information including the total number of strokes, stroke feature points, global position features, relative previous point features and transition zone features recorded in the historical structure and the target structure; and determining whether the identity authentication of the target user is passed based on the final comparison result.
[0066] Optionally, it can be determined whether the deviation between the total number of strokes recorded in the historical structure and the target structure is greater than or equal to a deviation threshold. If so, the comparison result for the total number of strokes is determined to be failed. Similarly, it can be determined whether the deviation of the stroke feature points, global position features, relative previous point features and transition zone features between the two is greater than or equal to a preset threshold, so as to determine the comparison results for the stroke feature points, global position features, relative previous point features and transition zone features, respectively, to obtain the final comparison result.
[0067] Exemplarily, it is possible to first determine whether the total number of strokes recorded in the historical structure and the target structure are equal. If they are not equal, the comparison result can be directly determined as failed. Further, if they are equal, it is possible to determine whether the stroke feature points between the two are greater than or equal to a preset first threshold. If not, it is possible to determine whether the deviation of the global position feature, relative previous point feature and transition zone feature between the two is greater than or equal to a preset second threshold.
[0068] Optionally, after determining that the total number of strokes meets the threshold condition, if one of the stroke feature points, global position features, relative front point features, and transition zone features meets the threshold condition, the final comparison result can be determined to be passed. The second threshold can be set to a value where the difference between x and y does not exceed three units.
[0069] Optionally, after determining that the total number of strokes meets the threshold condition, the identity authentication is considered to have passed when each of the stroke feature points, global position features, relative previous point features and transition zone features meets the corresponding threshold condition. The present invention does not impose any restrictions on this.
[0070] It should be noted that the above-mentioned embodiment of the present invention performs identity authentication by comparing the total number of strokes, stroke feature points, global position features, relative previous point features and transition zone features recorded in the historical structure and the target structure respectively, so as to more comprehensively compare the character information input by the target user and improve the accuracy of the target user's identity authentication.
[0071] The technical solution of the embodiment of the present invention, in response to the login request of the target user, instructs the target user to start inputting characters through a preset input device, and monitors the input process to obtain input character information; determines the historical structure corresponding to the historical input characters of the target user from the preset font library, and determines the target structure corresponding to the input character information; compares the historical structure and the target structure, and determines whether the identity authentication of the target user is passed according to the comparison result, so as to respond to the login request. By accurately monitoring and verifying the character information input by the user, the user identity can be accurately verified, and the security and effectiveness of the interaction process can be improved.
[0072] Embodiment 2
[0073] Figure 2 is a flowchart of a login verification method provided by Embodiment 2 of the present invention; based on the above embodiment, this embodiment provides a preferred example of performing login verification on a target user according to a target structure and a history structure, specifically, Figure 2 As shown, the method includes:
[0074] S201. In response to a login request from a target user, if the preset input device is a mouse, instruct the target user to input characters by pressing the left button of the mouse, sliding the mouse, and lifting the left button of the mouse.
[0075] S202: If the preset input device is an electronic pen and a screen sensor, instruct the target user to input characters by controlling the electronic pen to touch and slide on the screen sensor.
[0076] S203: Determine the sub-input process of each character stroke in the input process according to the device type of the preset input device, and determine the stroke feature points corresponding to each character stroke according to the sub-input process.
[0077] S204: Determine a target feature point from the stroke feature points, and determine a global position feature, a relative previous point feature, and a transition zone feature corresponding to the target feature point.
[0078] S205: Determine input character information according to the total number of strokes, stroke feature points, global position features, relative previous point features, and transition zone features.
[0079] S206: Determine a history structure corresponding to the target user's historical input characters from a preset font library, and determine a target structure corresponding to the input character information.
[0080] S207, respectively determining whether the total number of strokes, stroke feature points, global position features, relative previous point features, and transition zone features recorded in the history structure and the target structure meet corresponding threshold conditions.
[0081] S208: If the total number of strokes, stroke feature points, global position features, relative front point features, and transition zone features all meet corresponding threshold conditions, it is determined that the identity authentication of the target user is passed.
[0082] The technical solution of the present invention proposes a login verification method that is more in line with the user's personal habits. By storing the characters written by the user in a preset character library in advance, the user only needs to write the characters once according to some previous characteristics to complete the verification during the login verification, thereby ensuring the security of the verification process while improving the verification efficiency and accuracy.
