Detailed ways

Verification codes are used as a verification method for authenticating end users. The verification codes include: text verification codes, graphic verification codes, sliding verification codes, SMS verification codes, and voice verification codes. Figure 1 is a schematic diagram of a static trajectory, and Figure 2 is a schematic diagram of the verification process of a static trajectory. The verification process of a static trajectory shown in Figure 2 includes: Step 201: the server generates a demonstration trajectory; Step 202: the client generates the demonstration trajectory generated by the server It is displayed on the display interface in a static form, and the demo track is used for the user to perform simulated drawing by sliding operation on the display interface; step 203: the user performs simulated drawing by sliding operation on the display interface; step 204: the client collects the user's Sliding operation, uploading the simulated trajectory generated based on the user’s sliding operation to the server; step 205: the server verifies the simulated trajectory and the demo trajectory, and returns the verification result; step 206: the verification is successful; step 207: Validation failed. However, sliding verification against static trajectories is easily recognized and simulated by machines.

Based on this, in the embodiment of the present invention, at least two trajectory segments are sequentially drawn on the display interface, and after the trajectory segment drawing is completed, the drawn corresponding trajectory segments are cleared on the display interface; the drawn at least two trajectory segments form the first trajectory ; Detect the user's touch operation, draw a second track on the display interface according to the touch operation; determine the verification result; the verification result is based on the matching degree between the first track and the second track definite.

In order to understand the characteristics and technical contents of the embodiments of the present invention in more detail, the implementation of the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. The attached drawings are only for reference and description, and are not intended to limit the present invention.

As shown in Figure 3, the verification method of the embodiment of the present invention is described in detail. The verification method of this embodiment is applied to the terminal side and includes the following steps:

Step 301: draw at least two trajectory segments sequentially on the display interface, and clear the drawn corresponding trajectory segments on the display interface after the trajectory segment drawing is completed; the drawn at least two trajectory segments form a first trajectory.

Here, after the drawing of the trajectory segment is completed, the drawn corresponding trajectory segment is cleared on the terminal display interface. In this way, the user can simulate the drawing of the first trajectory by virtue of memory. Since the trajectory segment is cleared after the drawing is completed, the machine can be prevented from obtaining it. Machine simulation is thus effectively prevented. In addition, the terminal can obtain the track segment from the server, so that the server can control the length of the track segment according to the memory level of different users, without increasing the difficulty of simulating the first track for the user.

The memory level of different users can be determined according to the time spent by the user in trajectory simulation. For example, the user’s memory level can be tested in advance, and the trajectory can be provided to the user for user simulation test, and the user’s memory can be determined according to the time spent in user testing The degree of memory, or, can also be determined according to the average time spent by the user on track verification in the past. The shorter the time-consuming, the stronger the degree of memory.

In one embodiment, the sequentially drawing at least two trajectory segments on the display interface includes: obtaining drawing parameters from a server; the drawing parameters include at least the coordinates of the starting point and end point of the trajectory segment, and the drawing sequence of the coordinate points; Utilize the coordinates in the drawing parameters to determine a dot matrix; use the starting point and end point coordinates of each trajectory segment to determine the position of the trajectory segment in the dot matrix; use the drawing order of the coordinate points in the drawing parameters , to determine the drawing sequence of the trajectory segments; draw the trajectory segments sequentially on the display interface according to the determined drawing sequence.

Here, the coordinates of the starting point and the end point of the track segment in the drawing parameters transmitted between the server and the terminal are text data, which not only takes up less storage space of the terminal compared with traditional picture verification codes, but also Ability to reduce consumed transmission traffic.

In one embodiment, the drawing of at least two trajectory segments sequentially on the display interface includes: the drawing parameters at least include the drawing speed and the drawing color of each trajectory segment; Drawing speed, drawing track segments; using the drawing color of each track segment in the drawing parameters, displaying the drawing color of the track segments as the corresponding drawing color in the drawing parameters.

In actual application, the terminal can control the drawing speed of the trajectory segment according to the drawing speed in the drawing parameters obtained from the server. In this way, for users with super memory, the speed of drawing the trajectory segment can be accelerated, which helps to improve the user simulation first time. A track experience. In addition, the terminal can control the display color of the trajectory segment according to the drawing color in the drawing parameters obtained from the server. In this way, the display color of the drawn trajectory can be controlled in combination with the user's preference for color, which also helps to improve the user's ability to simulate the first trajectory. Experience; the user's color preference can be obtained by testing the user's color preference.

In practical applications, the drawing parameters may also include a trajectory drawing timing. After receiving the trajectory drawing timing sent by the server, the terminal displays the trajectory segment on the display interface according to the trajectory drawing timing. The trajectory drawing timing may not be fixed. , so that the time of trajectory drawing is random, it is not easy to be obtained by the machine, and the security is high.

Step 302: Detect a user's touch operation, and draw a second track on the display interface according to the touch operation.

Here, the trajectory segments of the first trajectory can be dynamically drawn on the dot matrix displayed on the display interface. After the first trajectory is drawn, the user can redraw on the same dot matrix by relying on the memory of the trajectory segments in the first trajectory.

Wherein, the dot matrix may be determined by the terminal according to the coordinates of the start point and end point of the trajectory segment in the drawing parameters sent by the server, and at least one dot matrix may be determined by using a set of coordinates of the start point and end point of the trajectory segment; or, the The dot matrix is preset by the terminal according to the actual situation. That is, in this embodiment, the size of the dot matrix can also be determined dynamically, which can effectively prevent machine simulation.

During actual application, if the user uses a handheld terminal such as a mobile phone or a Pad, the second trajectory can be drawn through a touch screen; if the user uses a personal computer (PC, Personal Computer) end, the second trajectory can be drawn through a mouse. second track.

Step 303: Determine a verification result; the verification result is determined according to the degree of matching between the first track and the second track.

In an embodiment, the determining the verification result includes: sending information characterizing the second trajectory to the server; using the information for verification by the server; and receiving the verification result sent by the server.

In the verification method provided by the embodiment of the present invention, since the drawn corresponding trajectory segment is cleared on the display interface of the terminal after the trajectory segment is drawn, the terminal user can rely on the memory of the first trajectory formed by at least two trajectory segments, and display The touch operation is performed in the interface, and finally the second track is obtained. Obviously, relying on the user's memory of the dynamically drawn first trajectory to obtain the second trajectory reduces the possibility of machine simulation, can effectively avoid machine simulation, and at the same time helps to improve the verification success rate.

As shown in Figure 4, the verification method of the embodiment of the present invention is described in detail. The verification method of this embodiment is applied to the server side and includes the following steps:

Step 401: Receive information representing a second trajectory sent by the terminal; the second trajectory is drawn by the terminal according to a user's touch operation.

In actual application, if the user uses a handheld terminal such as a mobile phone or a Pad, the second trajectory can be drawn through a touch screen; if the user uses a PC terminal, the second trajectory can be drawn through a mouse.

Step 402: Obtain a verification result according to the degree of matching between the second trajectory and the first trajectory; the first trajectory is drawn by the terminal using at least two trajectory segments stored locally on the server; wherein the trajectory After the segment is drawn, it disappears on the display interface of the terminal.

Here, the trajectory segments of the first trajectory can be dynamically drawn on the dot matrix displayed on the terminal display interface. After the first trajectory is drawn, the user can redraw on the same dot matrix by relying on the memory of the trajectory segments in the first trajectory.

In one embodiment, the obtaining the verification result according to the degree of matching between the second track and the first track includes: using the second track to determine corresponding track segments; for each track segment, using In the information, corresponding to the trigger sequence of the user’s trigger operation and the coordinates of the trigger point, it is judged whether the track segment corresponding to the second track matches the track segment corresponding to the first track stored locally; Relevant information to obtain the account credibility of the terminal user; determine whether the terminal user account credibility is greater than a preset threshold; if it is determined to be greater than, the verification is successful; otherwise, the verification fails.

In actual application, the server matches the second trajectory with the first trajectory corresponding to the trajectory segment sent to the terminal, and when matched, obtains the user's account credibility from the risk control center, and uses the account credibility to determine whether the user is a machine , so that it can be identified whether the second trajectory is a machine simulation, and the verification recognition rate can be improved.

Step 403: Send the verification result to the terminal.

In one embodiment, before step 401, the method further includes: acquiring the account credibility of the terminal; using the account credibility, determining the coordinates of the starting point and the end point of each trajectory segment, and the drawing order of the coordinate points; The determined coordinates and the drawing order of the coordinate points are used as drawing parameters; the drawing parameters are used for the terminal to draw the first trajectory; and the drawing parameters are sent to the terminal.

The following describes in detail the structure of the verification system adopted in the embodiment of the present invention in practical applications, and the process and principle of realizing verification based on the structure.

FIG. 5 is a schematic diagram of a functional module framework of a terminal and a server according to an embodiment of the present invention. Specifically, as shown in FIG. 5, the structure of the verification system includes: a terminal, a server, and a risk control center; the functional modules of the terminal include: a dynamic drawing module of a verification track, and a receiving module of a user sliding track; wherein,

Verify trajectory dynamic drawing module, used to draw dynamic trajectory. Specifically, unlike the traditional static trajectory, the trajectory in this embodiment is dynamically drawn on the display interface, and the trajectory between two points disappears immediately after the completion of the trajectory drawing, and then the next section of trajectory is drawn, and the whole process is continuous and endless. Intermittent; the dynamic drawing may be that the terminal draws the trajectory segment according to a preset animation effect. After drawing all trajectories, it will return to the original dot matrix, that is, the dot matrix when there is no track. The user redraws on the dot matrix according to the track in memory. Here, the dynamic trajectory is more difficult to be recognized by the machine than the static trajectory. Since the dynamic trajectory is short, it does not increase the difficulty of recognition for real users.

The user sliding trajectory receiving module is configured to monitor touch events, draw the user's second trajectory based on the user's sliding touch operation, and upload the second trajectory to the server.

Taking the Android client as an example, the Canvas technology can be combined with Android's ValueAnimator attribute animation technology to realize the dynamic drawing and disappearance of the trajectory. Figure 6 is a schematic diagram of each trajectory segment dynamically drawn. The drawing process of the trajectory segment includes the following steps:

Step 1: Get trajectory segments.

FIG. 7 is a schematic diagram of trajectory segments, and the static trajectory shown in FIG. 7 includes three trajectory segments.

Step 2: Set the drawing effect.

According to the drawing parameters sent by the server, use ValueAnimator to set the animation effect; the drawing parameters include but not limited to the rate of drawing the trajectory, the drawing color of the trajectory, etc.;

Step 3: Draw the first trajectory segment.

Keep the starting point of the trajectory unchanged, dynamically modify the coordinates of the end point through ValueAnimator, and then use Canvas technology to continuously draw, and the trajectory drawing is completed when the animation ends.

Step 4: Draw the next track.

Move the starting point of the trajectory to the end position of the previous trajectory and keep it unchanged. Also dynamically modify the coordinates of the end point through ValueAnimator, and then use Canvas technology to continuously draw. At this point, the previous track has disappeared.

Step 5: Continue the operation of step 4 until the drawing of all segmented trajectories is completed.

Step 6: The track is cleared.

It should be noted that when clearing the trajectory, you can clear the drawn corresponding trajectory segment on the display interface of the terminal after the trajectory segment is drawn; you can also clear the first trajectory formed by all the trajectory segments after all the trajectory segments are drawn .

The process of clearing the first trajectory formed by all trajectory segments includes: keeping the end point of the last trajectory unchanged, dynamically modifying the starting point coordinates through ValueAnimator, and then using Canvas technology to continuously draw, the starting point gradually approaches the end point, and the animation ends. The track is cleared.

In Fig. 5, the functional modules of the server include: a verification trajectory generation module, a user sliding trajectory verification module; wherein,

Verify the trajectory generation module, used to obtain the coordinates of the starting point and the ending point of the trajectory point. Specifically, the account credibility of the corresponding terminal user is obtained from the account credibility storage module of the risk control center, and a set of random trajectory segment starting point and end point coordinates are customized according to the account credibility, and trajectory segments can also be customized The speed of drawing, that is, the time when the trajectory segment is drawn. For example, using the coordinates (1,1), (2,2), (2,3), (3,2) returned from the risk control center, the trajectory segment shown in Figure 7 can be determined, and three lines can also be determined Three-column binary lattice, the lattice includes nine position coordinates: (1,1), (1,2), (1,3), (2,1), (2,2), (2,3) , (3,1), (3,2), (3,3).

The user sliding trajectory verification module is used for the server to analyze and compare the second trajectory uploaded by the terminal with the corresponding first trajectory saved locally, and upload the information related to the second trajectory to the account credibility of the risk control center computing module. Combining the analysis and comparison results of the user sliding track verification module and the account credibility calculation module to determine whether the second track is verified successfully.

In Fig. 5, the risk control center includes: account credibility storage module, account credibility calculation module; wherein,

The account credibility storage module is used to store the user's account credibility and provide it to the server for customizing the complexity of the track segment.

The account credibility calculation module is used to analyze user behavior according to the relevant information of the second trajectory fed back by the server, and recalculate the user's account credibility to distinguish whether the user is a human or a machine.

The implementation process and principles of the present invention in practical applications will be described in detail below by taking specific embodiments as examples.

FIG. 8 is a schematic diagram of a specific implementation process of trajectory verification in an embodiment of the present invention. The specific implementation process includes the following steps:

Step 801: the server acquires the credibility of the terminal user's account from the risk control center.

Step 802: The server customizes the complexity of the trajectory segment according to the credibility of the account, generates a set of random coordinates of the starting point and the end point of the trajectory segment, and determines parameters such as the drawing speed and timing of the trajectory segment.

The trajectory drawing speed may be the speed at which the client displays the drawn trajectory to the user, and the trajectory drawing timing may be the time point at which the client displays the trajectory segment on the display interface after receiving the trajectory segment returned by the server. For accounts with low credibility, the complexity of drawing can be increased, such as increasing the number of drawn coordinate points, speeding up drawing, and so on.

Step 803: The terminal dynamically draws the track according to the drawing speed, drawing timing, and track segment coordinates returned by the server, and clears the track segment after drawing the track segment.

Step 804: The user simulates the first trajectory on the client interface according to the memory of the dynamically drawn first trajectory displayed on the terminal.

Step 805: the terminal collects the second trajectory drawn by the user, and uploads information related to the second trajectory to the server;

Step 806: The server analyzes whether the uploaded second track matches the track segment corresponding to the first track sent to the client in advance;

Step 807: The server analyzes whether all the coordinate points of the second track are triggered, and whether the trigger sequence of each coordinate point matches the trigger sequence of each coordinate point of the first track;

Step 808: If it is satisfied, send the related information of the second track to the risk control center. The risk control center will analyze the user's behavior according to the relevant information, recalculate the user's account credibility, and return the recalculated account credibility to the server;

Step 808 is mainly to determine whether the operator is a machine according to the relevant information of the second trajectory. The relevant information of the second trajectory may include information such as the speed at which the user draws the second trajectory. If the drawing process of the second trajectory is at a constant speed, the operator It is more likely to be a machine, which will reduce the credibility of the account.

Step 809: The server determines whether the verification of the second track is successful according to the recalculated account credibility.

If the recalculated account credibility is higher than the set threshold, the verification is successful.

Step 810: the server returns the verification result to the terminal.
