Description

Method, device and system for safety verification

technical field

The present invention relates to the technical field of information security of Internet technology, in particular to a method, device and system for security verification.

Background technique

With the increasing popularity of computers and computer networks, the Internet has penetrated into all areas of people's work, study and life. While the development of the network provides convenience for people, it also brings various challenges. Some people will use robot programs to improperly use network resources in large quantities, such as mass spam, etc., which will greatly reduce server performance. There are also people who use the program to continuously send out service request responses to carry out "saturation attacks" to achieve the purpose of paralyzing the server. Some people even try to maliciously crack passwords by means of profiteering cracking. In order to avoid the above-mentioned malicious behaviors, it is very important to design a set of tools that can allow the computer to automatically distinguish whether the information comes from a legitimate user or a robot program that is improperly used.

Using image verification codes is a relatively common way now. The main purpose of image verification codes is to distinguish whether network service users are programs or humans. The image verification code is a picture containing a string, and the user is required to input the content of the string during verification. Strings are usually composed of uppercase and lowercase letters and numbers. Part of the verification code contains Chinese characters or mathematical formulas. The length of the string can be random or fixed. In order to avoid being automatically recognized by the machine, the background of the picture is usually improved, such as adding various texture patterns, etc., thereby interfering with the automatic recognition of the machine.

However, as long as enough samples are collected, machine learning and training using character recognition techniques, machine programs can be developed to decode image captchas. Even the improved image captcha can still be recognized by machines if its background library is not large enough. Traditional image verification codes cannot avoid this problem. Taking character image verification codes as an example, if there are uppercase and lowercase characters and numbers, there are only 62 characters at most. Therefore, the existing image verification code has poor anti-cracking ability and insufficient security.

first embodiment

Please refer to FIG. 3 , which is a flow chart of the security verification method provided by the first embodiment of the present invention. In conjunction with FIG. 1, what this embodiment describes is the processing flow of the server, and the method for security verification provided by this embodiment includes the following steps:

Step S11, the server sends the verification code to the user terminal for display, the verification code includes prompt information and multiple objects related to the prompt information.

The prompt information in the verification code in the embodiment of the present invention may be a multiple-choice question or a description of a certain transaction. According to the content of the prompt information, the user can select an object that matches the content of the prompt information among multiple objects in the verification code. Multiple objects in the verification code can be pictures, text, animation, voice, etc. Preferably, each object in the verification code corresponds to an object label. Preferably, each object in the verification code displayed on the user terminal may be a control that can be clicked or checked. The user can select the corresponding object by clicking or checking the control with a touch tool (such as a finger) or a mouse. Certainly, the user may also select the corresponding object in other ways, and the specific implementation manner of the present invention is not limited thereto. Further, please refer to FIG. 4, before step S11 may also include:

In step S101, the server selects a prompt information sample from the verification code database as the prompt information of the verification code.

The verification code database includes a plurality of prompt information samples and a plurality of object samples, each object sample in the plurality of object samples has a marking type corresponding to each prompt information sample, and the marking type includes at least the first A calibration type and a second calibration type.

The verification code database may be established in advance and set in the server. The multiple prompt information samples and multiple object samples in the verification code database may be obtained directly from the Internet by the server, or may be created by designers, and the specific implementation manner of the present invention is not limited thereto.

The prompt information sample is preferably a question that can be quickly understood by the user, such as a common-sense multiple-choice question. The object samples are preferably objects whose content can be quickly identified by the user. Preferably, the physical picture is used as the object sample. On the one hand, because the physical picture is relatively easy to obtain from the Internet, the number of object samples is relatively easy to reach a certain scale. On the other hand, with the existing computer development level, for a certain class It is more difficult to train a general classification program in kind. For example, the same picture of a car may have very large differences in the size, color, decoration, angle, etc. of the car. For such two samples, if using a machine It is difficult to complete the clustering process by means of learning to classify, so the use of physical pictures can more effectively improve the anti-cracking ability of the verification code.

Each prompt information sample may correspond to a prompt information identifier that uniquely identifies the prompt information sample, and each object sample may also correspond to an object identifier that uniquely identifies the object sample.

When initially establishing the verification code database, it is necessary to calibrate the calibration type of each object sample corresponding to each prompt information sample. Assuming that there are M prompt information samples and N object samples, a total of M*N calibrations are required. Initially Calibration can be done manually.

The calibration types of the object samples can be divided into four types: the first calibration type, the second calibration type, the third calibration type and the fourth calibration type.

For example, the first calibration type can be defined as "yes". If the calibration type of a certain object sample corresponding to a prompt information sample is the first calibration type, it means that the verification code using the prompt information sample as the prompt information is being verified. , the user needs to click on the object, that is to say, the object conforms to the prompt information.

The second calibration type can be defined as "no". If the calibration type of an object sample corresponding to a prompt information sample is the second calibration type, it means that when verifying the verification code that uses the prompt information sample as the prompt information, the user It is necessary not to click the object, that is to say, the object does not conform to the prompt information.

The third calibration type can be defined as "uncalibrated". If the calibration type of a certain object sample corresponding to a prompt information sample is the third calibration type, it means that the object sample has not been calibrated corresponding to the prompt information sample.

The fourth calibration type can be defined as "not suitable". If the calibration type of a certain object sample corresponding to a prompt information sample is the fourth calibration type, it means that the object sample should not appear in the same verification code as the prompt information sample .

In the following embodiments, in order to make the description of the technical solution simpler and clearer, the above-mentioned definitions of the first to fourth calibration types are also consistently used. However, it can be understood that in other specific implementation methods of the present invention, The names and specific definitions of the calibration types are interchangeable, for example, the first calibration type can be defined as "no", the second calibration type can be defined as "yes", etc.

Step S102, the server selects multiple object samples from the verification code database as multiple objects in the verification code according to the selected prompt information sample, wherein the selected multiple object samples The calibration type corresponding to the selected prompt information sample is the first calibration type, the second calibration type or the third calibration type, and at least one object sample corresponding to the calibration type of the selected prompt information sample is The first calibration type.

Suppose the server selects a prompt information sample A from the verification code database as the prompt information of the verification code, and then randomly selects a plurality of object samples B from the verification code database according to the prompt information sample A as multiple objects of the verification code, The calibration type of the multiple object samples B corresponding to the prompt information sample A may be the first calibration type, the second calibration type, or the third calibration type, but at least one object sample B corresponds to the prompt information sample A The calibration type of is the first calibration type. It should be noted that in a verification code, the number of object samples B whose calibration type is the third calibration type cannot be too much, and the number of object samples B whose calibration type is the third calibration type has at least one possibility in this verification code It is advisable to enable the user to pass the authentication. It can be understood that for different verification codes, on the premise that there is at least one possibility for the user to pass the verification, the number of object samples B whose calibration type is allowed to be the third calibration type is different. Therefore, the calibration type is The number of object samples B of the third calibration type should be set according to the actual situation, and the preferred number can be 1.

Undertake the above definition of the calibration type, that is to say, at least one object in the verification code conforms to the prompt information, and other objects may not conform to the prompt information, or may not be calibrated corresponding to the prompt information sample , but the object sample whose calibration type is the fourth calibration type will not be selected as the object of the verification code, because the calibration type is the fourth calibration type, indicating that the object sample should not appear in the same verification code as the prompt information sample .

It can be understood that for the same prompt information sample, the combination of corresponding object samples selected by the server each time may be different, and similarly, for the same group of object samples, the corresponding prompt information may also be different. Therefore, the more the prompt information samples and the object samples are, the more the verification codes are.

Step S103, the server sends the selected prompt information sample and the selected object samples to the user terminal for display.

The server can randomly label the multiple selected object samples, and the server can send the multiple object samples to the user terminal according to the sequence of labeling. The server may also generate a correspondence table of the verification code. The correspondence table includes the prompt information identifier of the prompt information in the verification code, the label of each object in the verification code, and the object identifier corresponding to each object. The corresponding relationship table may also include the label type corresponding to each object.

Each verification code may correspond to a verification code identifier that uniquely identifies the verification code, and the verification code identifier is also stored in the correspondence table.

When the server sends the verification code to the user terminal, it may also send the prompt information identifier in the verification code to the user terminal, or send the verification code identifier of the verification code to the user terminal, or send the object label in the verification code to the user terminal. The user terminal, or the correspondence table of the verification codes may also be sent to the user terminal.

Step S12, receiving the information of the selected object returned by the user terminal according to the user's selection of the plurality of objects.

The user terminal returns the information of the selected object to the server according to the user's selection of the plurality of objects. The server receives the information of the selected object returned by the user terminal. The information of the selected object includes at least the verification code identifier of the verification code. The information of the selected object at least includes a label of the selected object or an object identifier of the selected object.

Step S13, calculate the verification pass value T0 according to the information of the selected object and predetermined rules, if the verification pass value T0 exceeds the first threshold T1, the verification result is judged to be passed, otherwise, the verification result is judged to be failed.

Multiple objects can be divided into a first set P1 and a second set P2 according to the marking types of multiple objects in the verification code. For example, objects whose marking type is the first marking type can be classified into the first set P1, and the Objects whose marking type is the second marking type are included in the second set P2. Since at least one of the objects in the verification code has a marking type of the first marking type, at least one object belongs to the first set P1. Classify the objects selected by the user into the third set P'.

respectively calculating the first degree of coincidence between the third set P' and the first set P1, and the second degree of coincidence between the third set P' and the second set P2, according to the first degree of coincidence, The verification passing value T0 is calculated by the second coincidence degree and a predetermined rule. If the verification pass value T0 exceeds the first threshold T1, it is determined that the verification result is passed; otherwise, it is determined that the verification result is not passed. The predetermined rule may include that the greater the first degree of coincidence is greater than the second degree of coincidence, the higher the verification value T0 is, on the contrary, the greater the second degree of coincidence is greater than the first degree of coincidence, the lower the verification value T0 is.

Specifically, the weight of the calibration type of the object sample Bi corresponding to the prompt information sample Aj can be defined as Ci, j, if the calibration type is the first calibration type, then set Ci,j=1; if the calibration type is the second calibration type , then set Ci,j=-1; if the calibration type is the third calibration type, then set Ci,j=0; if the calibration type is the fourth calibration type, keep the original processing method. If the marked type Ci,j=1 of the object in the verification code, it means that the object belongs to the first set P1, and if the marked type Ci,j=-1 of the object in the verification code, it means that the object belongs to the second set P2.

When calculating the verification pass value T0, assuming that there are P objects in the verification code, the verification pass value T0 can be calculated by formula (1):

Among them, Ki corresponds to the user's choice, if the user selects the object corresponding to the object sample Bi, that is, the object sample Bi belongs to the third set, then Ki=1; if the user does not select the object corresponding to the object sample Bi, that is, the object sample Bi does not belong to the third set, then Ki=-1.

The calibration types of the P objects in the verification code can be searched in the verification code correspondence table according to the verification code identifier returned by the user terminal. Whether the user has selected the object corresponding to the object sample Bi can be determined according to the selected Object information is determined. Specifically, if the information of the selected object includes the label of the selected object, the server can look up the object sample corresponding to the label in the verification code correspondence table, so as to determine whether the selected object includes the object sample Bi; if the selected object If the information includes the object identifier of the selected object, it can be directly judged according to the object identifier whether the selected object includes the object sample Bi.

Comparing the calculated verification pass value T0 with the preset first threshold T1, if the verification pass value T0 exceeds (greater than or equal to) the first threshold T1, the verification result is judged to be passed; otherwise, the verification result is judged to be failed .

In the technical solution provided by this embodiment, the verification code sent by the server to the user terminal includes prompt information and multiple objects related to the prompt information, and the user terminal sends the information of the selected object according to the user's selection of the multiple objects Returning to the server, the server calculates the verification pass value T0 according to the information of the selected object and predetermined rules, and then compares the verification pass value T0 with the preset first threshold T1 to determine whether the verification result is passed. The security verification method in the embodiment of the present invention, on the one hand, makes full use of the inherent advantages of human beings in classifying things, and calculates the verification passing value according to the user's selection of the object in the verification code. Since the machine understands the prompt information and the object There are great difficulties in these two aspects of the classification, so it greatly increases the difficulty of the machine cracking the verification code. On the other hand, since the user does not need 100% to select the object that meets the prompt information, some errors are allowed to exist. It is easy for the user to successfully pass the verification without increasing the burden on the user. That is to say, the present invention can greatly improve the cracking resistance of the verification code without affecting the user experience, and effectively improve the security of user verification.

second embodiment

This embodiment provides a method for security verification. In combination with the content of the first embodiment above, refer to FIGS. 5 to 7. The method provided by this embodiment specifically includes:

Step S21, acquiring a new object sample and storing the new object sample in a verification code database, the verification code database including a plurality of prompt information samples and a plurality of object samples, each of the plurality of object samples Each object sample has a marking type corresponding to each prompt information sample, and the marking type includes at least a first marking type and a second marking type.

Since the verification code is used continuously, the object sample and the prompt information sample need to be continuously updated. After the server obtains the new object sample, for example, through the Internet, the new object sample is stored in the verification code database. Regarding the verification code database, for details, reference may be made to the relevant description in the first embodiment, which will not be repeated here. For a newly added object sample, by default, the calibration type corresponding to each prompt information sample can be set as the third calibration type, to indicate that the object sample has not been calibrated corresponding to the prompt information sample.

Step S22, the server selects a prompt information sample from the verification code database as the prompt information of the verification code.

Step S23, the server selects a plurality of object samples from the verification code database as the plurality of objects in the verification code according to the selected prompt information sample, wherein the selected object samples includes one of the new object samples, and the marking type of the new object sample corresponding to the prompt information in the verification code is the third marking type.

Assuming that the prompt information sample selected by the server is Ai, the object sample selected by the server according to the prompt information sample Ai includes a new object sample Bn, and the calibration type of the new object sample Bn corresponding to Ai of the prompt information sample is the first Three calibration types. On the premise that there is at least one possibility for the user to pass the verification, the number of new object samples Bn in the verification code can also exceed one.

In step S24, the server sends the verification code to the user terminal for display.

The server sends the selected prompt information sample Ai and the selected multiple object samples (including the new object sample Bn) to the user terminal, that is to say, the server sends the new object sample Bn together with the prompt information sample Ai to the user terminal authenticating.

Assume that the verification code sent includes P objects, of which P1 objects are of the first calibration type, P2 are of the second calibration type, and P3 are of the third calibration type , wherein the number of P3 is preferably one.

Step S25, receiving the information of the selected object returned by the user terminal according to the user's selection of the plurality of objects.

Step S26: Calculate the verification pass value T0 according to the information of the selected object and predetermined rules. If the verification pass value T0 exceeds the first threshold T1, the verification result is determined to be passed; otherwise, the verification result is determined to be failed.

For this step, reference may be made to the corresponding steps in the first embodiment, which will not be repeated here.

Step S27, if the verification pass value T0 calculated by the server exceeds the second threshold T2, modify the new object sample corresponding to the verification code according to the user's selection of the new object sample. The calibration type of the prompt message.

The second threshold T2 may be greater than or equal to the first threshold T1, preferably, the second threshold T2 is greater than the first threshold T1. Specifically, when the second threshold T2 is greater than the first threshold T1, it can be divided into the following situations:

If the verification passing value T0 does not exceed or be lower than the first threshold T1, the verification fails, and the calibration type of the new object sample is not modified;

If the verification passing value T0 exceeds the first threshold T1 but does not exceed the second threshold T2, the verification is passed, but the calibration type of the new object sample is not modified;

If the verification pass value T0 exceeds the second threshold T2, since the second threshold T2 is greater than or equal to the first threshold T1, it can be considered that the user's selection of the new object sample under the current prompt information is also correct, so it can be based on the user's The selection of the new object sample, modifying the new object sample corresponds to the marking type of the prompt information in the verification code.

Further, referring to FIG. 6, step S27 may include:

Step S271, counting the first marking type and the second marking type of the new object sample according to the user's selection of the new object sample;

If the user selects a new object sample Bn, the first labeling type of the new object sample Bn is counted, that is, the first labeling type is voted on. Assuming that the original count value of the first calibration type of the new object sample Bn is C0, and C0=0, after counting, the count value C1 of the first calibration type of the new object sample Bn=C0+1.

If the user does not select the new object sample Bn, the second marking type of the new object sample Bn is counted, which can also be said to be voting for the second marking type. Assuming that the original count value of the second calibration type of the new object sample Bn is C0, and C0=0, after counting, the count value C2 of the second calibration type of the new object sample Bn=C0+1.

Step S272, collecting choices of multiple users on the new object sample in the verification code,

Collect a large number of users' choices of the same new object sample Bn under the same prompt information.

Step S273, judging whether the sum of the count value of the first calibration type and the count value of the second calibration type reaches a predetermined count value;

If so, execute step S274, according to the weight of the count value of the first calibration type and the count value of the second calibration type, modify the calibration type of the new object sample corresponding to the prompt information in the verification code ;

Wherein, the weight R1 of the count value of the first calibration type=C1/(C1+C2), and the weight value of the count value of the second calibration type R2=C2/(C1+C2).

If not, execute step S275 without modification.

Further, referring to FIG. 7, step S274 may include:

Step S2741, judging whether the weight of the count value of the first calibration type is greater than the weight of the count value of the second calibration type,

If it is greater, then execute step S2742 to determine whether the difference between the weight of the count value of the first calibration type and the weight of the count value of the second calibration type reaches a predetermined difference, if yes, then execute step S2743: The marking type of the new object sample corresponding to the prompt information in the verification code is changed to the first marking type, otherwise, step S2744 is executed to change the marking type of the new object sample to the fourth marking type,

If not, execute step S2745 to determine whether the difference between the weight of the count value of the second calibration type and the weight of the count value of the first calibration type reaches the predetermined difference, if yes, execute step S2746, Modify the marking type of the new object sample corresponding to the prompt information in the verification code to the second marking type, otherwise, perform step S2747: modify the marking type of the new object sample to the fourth marking type type.

Specifically, if R1 is greater than R2, and the difference between R1 and R2 reaches a predetermined difference, it means that the calibration type of the new object sample is the weight of the first calibration type is much higher than the weight of the second calibration type, then it can be determined that The calibration type of the new object sample should be changed to the first calibration type.

If R1 is less than R2, and the difference between R2 and R1 reaches a predetermined difference, it means that the calibration type of the new object sample is the weight of the second calibration type is much higher than the weight of the first calibration type, and the new object can be identified The calibration type of the sample should be changed to the second calibration type.

If R1 is greater than R2, but the difference between R1 and R2 does not reach the predetermined difference, or if R1 is smaller than R2, but the difference between R2 and R1 does not reach the predetermined difference, it means that the calibration type of the new target sample is the first calibration type If the weight value is not much different from the weight value of the second calibration type, it can be determined that the current prompt information Ai is not applicable to the new object sample. Therefore, the calibration type of the new object sample should be changed to the fourth calibration type.

So far, the automatic calibration of the new object sample Bn corresponding to the prompt information Ai has been completed, as long as the above steps are repeated for each prompt information, the automatic calibration of the new object sample Bn corresponding to all the prompt information can be completed.

In the technical solution provided by this embodiment, the server sends new object samples and other object samples together with prompt information to the user terminal, the user terminal returns the information of the selected object to the server according to the user's selection of the object, and the server Information and predetermined rules calculate the verification pass value T0, and then determine whether the verification result is passed by comparing the verification pass value T0 with the preset first threshold T1. Further, the server also compares the verification pass value T0 with the second threshold T2, If the verification pass value T0 exceeds the second threshold T2, according to the user's selection of the new object sample, the new object sample is modified to correspond to the calibration type of the prompt information in the verification code, thereby realizing The automatic calibration of new object samples does not require manual calibration of new object samples, thereby improving efficiency.

third embodiment

This embodiment provides a method for security verification. In combination with the contents of the first and second embodiments above, see FIG. 8 and FIG. 10 , the method provided by this embodiment specifically includes:

Step S31, acquiring a new prompt information sample and storing the new prompt information sample in the verification code database, the verification code database including a plurality of prompt information samples and a plurality of object samples, the plurality of object samples Each object sample in the sample has a marking type corresponding to each prompt information sample, and the marking type includes at least a first marking type and a second marking type;

After the server acquires the new sample of prompt information, for example, through the Internet, the server stores the new sample of prompt information in the verification code database. Regarding the verification code database, for details, reference may be made to the relevant description in the first embodiment, which will not be repeated here.

Step S32, obtaining the calibration type of some object samples in the plurality of object samples corresponding to the new prompt information sample, and corresponding other object samples in the plurality of object samples to the new prompt information sample The calibration type of is set to the third calibration type;

Specifically, a small batch of object samples, such as several hundred, can be randomly selected in the verification code database, and manual calibration is performed on each of these object samples corresponding to the calibration type of the new prompt information sample, and the server obtains the Part of the object samples in the multiple object samples correspond to the calibration type of the new prompt information sample, and set the calibration type of other object samples in the verification code database corresponding to the new prompt information sample to the third calibration type , that is, "uncalibrated". Step S33, the server uses the new prompt information sample as the prompt information of the verification code;

Step S34, the server selects a plurality of object samples from the verification code database as a plurality of objects in the verification code according to the new prompt information sample, wherein the plurality of object samples include at least one A calibrated object sample and at least one uncalibrated object sample, the calibrated object sample is an object sample that has been calibrated corresponding to the new prompt information sample, and the uncalibrated object sample is corresponding to the new prompt information sample The calibration type of is the object sample of the third calibration type.

Assuming that the new prompt information sample is Anew, the object samples selected by the server according to the new prompt information sample Anew include at least one calibrated object sample and at least one unmarked object sample, and the unmarked object sample corresponds to the new prompt information The calibration type of the sample Anew is the third calibration type. In this way, the calibration process in which the current object sample corresponds to the newly added prompt information sample can be transformed into the calibration process in the second embodiment in which the newly added object sample corresponds to the current prompt information sample.

Step S35, the server sends the verification code to the user terminal for display;

Step S36, receiving the information of the selected object returned by the user terminal according to the user's selection of the plurality of objects; and

Step S37, calculate the verification pass value T0 according to the information of the selected object and predetermined rules, if the verification pass value T0 exceeds the first threshold T1, the verification result is judged to be passed, otherwise, the verification result is judged to be failed.

For steps S35 to S37, reference may be made to corresponding steps in the foregoing embodiments, and details are not repeated here.

Step S38, if the verification passing value calculated by the server exceeds the third threshold T3, modify the marking type of the unmarked object sample according to the user's selection of the unmarked object sample.

The third threshold T3 may be greater than or equal to the first threshold T1, and the third threshold T3 may be the same as or different from the second threshold T2. Preferably, the third threshold T3 is greater than the first threshold T1. Specifically, when the third threshold T3 is greater than the first threshold T1, it can be divided into the following situations:

If the verification passing value T0 does not exceed or be lower than the first threshold T1, the verification fails, and the calibration type of the uncalibrated object sample is not modified;

If the verification passing value T0 exceeds the first threshold T1 but does not exceed the third threshold T3, the verification is passed, but the calibration type of the uncalibrated object sample is not modified;

If the verification pass value T0 exceeds the third threshold T3, since the third threshold T3 is greater than or equal to the first threshold T1, it can be considered that the user’s choice of the unmarked object sample under the new prompt information is also correct, so it can be based on the user’s For the selection of unmarked object samples, modify the unmarked object samples corresponding to the marking type of the new prompt information in the verification code.

Further, referring to FIG. 9, step S38 may include:

Step S381, counting the first calibration type and the second calibration type of the unlabeled object samples according to the user's selection of the unlabeled object samples;

If the user selects an unlabeled object sample, the first labeling type of the unlabeled object sample is counted, that is to say, the first labeling type is voted on. Assuming that the original count value of the first calibration type of the uncalibrated object sample is C0, and C0=0, then after counting, the count value C1 of the first calibration type of the uncalibrated object sample Bn=C0+1.

If the user does not select the unmarked object sample Bn, the second marking type of the unmarked object sample Bn is counted, which can also be said to be a vote for the second marking type. Assuming that the original count value of the second calibration type of the uncalibrated object sample Bn is C0, and C0=0, then after counting, the count value C2 of the second calibration type of the uncalibrated object sample Bn=C0+1.

Step S382, collecting choices of multiple users on the unmarked object samples in the verification code,

Collect a large number of users' choices of the same unlabeled object sample under the same new prompt information.

Step S383, judging whether the sum of the count value of the first calibration type and the count value of the second calibration type reaches a predetermined count value,

If so, execute step S384, modify the calibration type of the unmarked object sample corresponding to the prompt information in the verification code according to the weight of the count value of the first calibration type and the count value of the second calibration type .

Wherein, the weight R1 of the count value of the first calibration type=C1/(C1+C2), and the weight value of the count value of the second calibration type R2=C2/(C1+C2).

If not, execute step S385 without modification.

Further, please refer to FIG. 10, wherein step S384 may include:

Step S3841, judging whether the weight of the count value of the first calibration type is greater than the weight of the count value of the second calibration type,

If it is greater, then execute step S3842 to determine whether the difference between the weight of the count value of the first calibration type and the weight of the count value of the second calibration type reaches a predetermined difference, if yes, then execute step S3843 to convert the The calibration type of the unlabeled object sample corresponding to the prompt information in the verification code is changed to the first calibration type, otherwise, step S3844 is performed to modify the calibration type of the unlabeled object sample to the fourth calibration type,

If not, execute step S3845 to determine whether the difference between the weight of the count value of the second calibration type and the weight of the count value of the first calibration type reaches the predetermined difference, if yes, execute step S3846, Modify the marking type of the unmarked object sample corresponding to the prompt information in the verification code to the second marking type, otherwise, perform step S3847 to change the marking type of the unmarked object sample to the fourth Calibration type.

Specifically, if R1 is greater than R2, and the difference between R1 and R2 reaches a predetermined difference, it means that the calibration type of the uncalibrated target sample is the weight of the first calibration type is much higher than the weight of the second calibration type, then you can The calibration type of the uncalibrated target sample should be changed to the first calibration type.

If R1 is less than R2, and the difference between R2 and R1 reaches a predetermined difference, it means that the calibration type of the uncalibrated object sample is the weight of the second calibration type is much higher than the weight of the first calibration type, then it can be determined that it is uncalibrated The calibration type of the object sample should be changed to the second calibration type.

If R1 is greater than R2, but the difference between R1 and R2 does not reach the predetermined difference, or if R1 is smaller than R2, but the difference between R2 and R1 does not reach the predetermined difference, it means that the calibration type of the uncalibrated target sample is the first calibration type The weight of the weight is not much different from the weight of the second calibration type, then it can be determined that the new prompt information Anew is not applicable to the uncalibrated object samples. Therefore, the calibration type of the uncalibrated object samples should be changed to the fourth calibration type.

So far, the automatic calibration of unmarked object samples corresponding to new prompt information has been completed. As long as the above steps are repeated for each new prompt information, the uncalibrated object samples corresponding to all new prompt information can be completed. Automatic calibration.

In the technical solution provided by this embodiment, the server sends new prompt information, object samples that have been calibrated corresponding to the new prompt information, and uncalibrated object samples to the user terminal, and the user terminal sends the selected object according to the user's selection of the object. The information is returned to the server, and the server calculates the verification pass value T0 according to the information of the selected object and predetermined rules, and then compares the verification pass value T0 with the preset first threshold T1 to determine whether the verification result is passed. Further, the server also Comparing the verification pass value T0 with the third threshold T3, if the verification pass value T0 exceeds the third threshold T3, modify the unmarked object sample corresponding to the verification code according to the user's selection of the unmarked object sample The new calibration type of prompt information only needs to obtain a small number of object samples corresponding to the calibration of the newly added prompt information samples, and then the calibration of the current object samples corresponding to the newly added prompt information samples can be realized, which improves the efficiency.

Fourth embodiment

This embodiment provides a method for security verification. Combining the contents of the first, second, and third embodiments above, refer to FIG. 11 and FIG. 12. The method provided by this embodiment specifically includes:

Step S41, the server selects a prompt information sample from the verification code database as the prompt information of the verification code, and the verification code database includes a plurality of prompt information samples and a plurality of object samples, and the plurality of Each object sample in the object sample has a marking type corresponding to each prompt information sample, and the marking type includes at least a first marking type and a second marking type;

Step S42, the server selects a plurality of object samples from the verification code database as the plurality of objects in the verification code according to the selected prompt information sample, wherein the selected object samples The marking type corresponding to the selected prompt information sample is the first marking type or the second marking type, and at least one object sample corresponding to the marking type of the selected prompt information sample is the first marking type.

Step S43, the server sends a verification code to the user terminal for display, the verification code includes prompt information and multiple objects related to the prompt information;

Step S44, receiving the information of the selected object returned by the user terminal according to the user's selection of the plurality of objects;

Step S45, calculate the verification pass value T0 according to the information of the selected object and predetermined rules, if the verification pass value T0 exceeds the first threshold T1, the verification result is judged to be passed, otherwise, the verification result is judged to be failed.

Steps S41 to S45 can refer to the corresponding steps in the above-mentioned embodiment, the difference is that in this embodiment, the calibration types of the selected object samples corresponding to the selected prompt information samples are respectively the first calibration type Or the second calibration type, that is to say, all the selected object samples have been calibrated corresponding to the selected prompt information samples.

Step S46, if the verification result is passed, it is judged whether the verification passing value T0 exceeds the fourth threshold T4.

The fourth threshold T4 may be greater than or equal to the first threshold T1, and the fourth threshold T4 may be the same as or different from the second threshold T2 or the third threshold T3. Preferably, the fourth threshold T4 is greater than the first threshold T1. Specifically, when the fourth threshold T4 is greater than the first threshold T1, it can be divided into the following situations:

If the verification passing value T0 does not exceed or be lower than the fourth threshold T4, the verification fails, and the calibration type of the target sample is not corrected;

If the verification passing value T0 exceeds the first threshold T1 but does not exceed the fourth threshold T4, the verification is passed, but the calibration type of the target sample is not corrected;

If the verification pass value T0 exceeds the fourth threshold T4, since the fourth threshold T4 is greater than or equal to the first threshold T1, it can be considered that the user's selection of the object sample under the current prompt information is also correct, so it can be based on the user's selection of the object. Sample selection, correct the object sample corresponding to the calibration type of the current prompt message.

That is to say, if the verification pass value T0 exceeds the fourth threshold T4, step S461 is executed to judge whether the selection of the object by the user matches the marked type of the object in the verification code database, and if not, then According to the selection of the user, the marking type of the object in the verification code database is modified.

If not, execute step S462 without modification.

Specifically, referring to FIG. 12, step S461 may include:

Step S4611, judging whether the selection of the object by the user is consistent with the marking type of the object in the verification code database,

If they match, execute step S4612 to correctly count the marking type of the object corresponding to the prompt information in the verification code;

If not, execute step S4613 to count the errors of the object corresponding to the marking type of the prompt information in the verification code;

Assuming that the verification code includes prompt information Ai and object Bj, and the sample corresponding to object Bj corresponds to the calibration type of prompt information Ai as the first calibration type, if the user selects object Bj, it is considered that the user’s selection of object Bj is consistent with the object Bj If the marking types in the verification code database are consistent, then the correct counting of the marking type of the object Bj corresponding to the prompt information Ai is performed, that is, adding 1 to the correct counter of the marking type of the object Bj corresponding to the prompt information Ai. Similarly, assuming that the sample corresponding to the object Bj corresponds to the calibration type of the prompt information Ai as the second calibration type, if the user does not select the object Bj, it is considered that the user's selection of the object Bj is consistent with the object Bj in the verification code database. If the calibration types match, then the correct counting of the calibration type of the object Bj corresponding to the prompt information Ai is performed, that is, adding 1 to the correct counter of the calibration type of the object Bj corresponding to the prompt information Ai.

In this case, assuming that the original count value of the correct counter of the calibration type of the object Bj is X0, and X0=0, then after counting, the count value of the correct counter of the calibration type of the object Bj is X=X0+1.

Assuming that the sample corresponding to the object Bj corresponds to the calibration type of the prompt information Ai as the second calibration type, if the user selects the object Bj, it is considered that the user's selection of the object Bj is the same as the calibration type of the object Bj in the verification code database. If they do not match, count the error of the calibration type of the object Bj corresponding to the prompt information Ai, that is, add 1 to the error counter of the calibration type of the object Bj corresponding to the prompt information Ai. Similarly, assuming that the sample corresponding to the object Bj corresponds to the calibration type of the prompt information Ai as the first calibration type, if the user does not select the object Bj, it is considered that the user's selection of the object Bj is consistent with the object Bj in the verification code database. If the calibration types do not match, the error count is performed on the calibration type of the object Bj corresponding to the prompt information Ai, that is, the error counter of the calibration type of the object Bj corresponding to the prompt information Ai is added by 1.

In this case, assuming that the original count value of the error counter of the calibration type of the object Bj is Y0, and Y0=0, then after counting, the count value of the error counter of the calibration type of the object Bj is Y=Y0+1.

Step S4614, collect multiple users' selections of the objects in the verification code and the correct count and error count of each object, and calculate the ratio of the wrong count to the correct count for each object in the verification code, when the ratio When it is greater than the lowest threshold and less than the highest threshold, modify the marking type setting of the object corresponding to the prompt information in the verification code to the fourth marking type. When the ratio is greater than or equal to the highest threshold, if the object’s The original calibration type is the first calibration type, then modify the calibration type of the object to the second calibration type, if the original calibration type of the object is the second calibration type, then modify the calibration type of the object to the first Calibration type.

Specifically, a large number of users' choices of the same object under the same prompt information may be collected. The ratio of the error count to the correct count of each object in the verification code refers to the ratio Q of the error count to the correct count of each object in the verification code corresponding to the current prompt information, where Q=Y/X.

If the ratio Q is greater than the lowest threshold Qmin and smaller than the highest threshold Qmax, it can be considered that the object is not suitable for use under the current prompt, and the calibration type corresponding to the current prompt information of the object is changed to the fourth calibration type.

If the ratio Q is greater than or equal to the highest threshold Qmax, it can be considered that the original calibration type of the object corresponding to the current prompt message has an error. If the original calibration type of the object is the first calibration type, the calibration type of the object is modified is the second calibration type, if the original calibration type of the object is the second calibration type, then modify the object’s calibration type to the first calibration type.

So far, the automatic correction of the object Bj corresponding to the prompt information Ai has been completed, as long as the above steps are repeated for each prompt information, the automatic correction of the object sample corresponding to all the prompt information can be completed.

Further, if the number of object samples whose calibration type is the fourth calibration type corresponding to the same prompt information sample in the verification code database exceeds a predetermined number, the prompt information sample can be marked, or the prompt information sample can be marked. That is to say, if the answer of a prompt message is changed to "Not Applicable" for many or even most objects, it means that the prompt message sample itself is not suitable as a prompt message or most of the current object samples are not applicable. The prompt information sample, therefore, can be marked for the manual to determine whether to delete the prompt information sample or specifically add a new object sample.

In other specific implementations, it is also possible to determine whether to correct the calibration type of the object by comparing the weight of the correct count and the weight of the wrong count.

Among them, the weight value Q1 of correct counting=X/(X+Y), and the weight value of wrong counting value Q2=Y/(X+Y).

Specifically, step 4614 may be replaced by the following steps:

Collecting multiple users' selections of the objects in the verification code and the correct count and wrong count of each object, and calculating the weight of the correct count and the weight of the wrong count of each object in the verification code;

Judging whether the weight of the wrong count is greater than the weight of the correct count, if it is greater, then judge whether the difference between the weight of the wrong count and the weight of the correct count reaches a predetermined difference, if so, according to the user's weight of the object sample Select, correct the calibration type of the object sample corresponding to the current prompt information and modify the weight Ci,j of the calibration type to -sign(Ci,j)*Q2, otherwise, modify the calibration type of the object sample to the fourth calibration type,

If it is not greater than, judge whether the difference between the weight of the correct count and the weight of the wrong count reaches the predetermined difference, if yes, do not correct the calibration type, but modify the weight Ci,j of the calibration type to sign(Ci ,j)*Q1.

Specifically, it is assumed that the object sample Bj corresponds to the weight of the correct count Q1=0.4, the weight of the wrong count Q2=0.6, the weight of the calibration type corresponding to the prompt information sample Ai, and the weight of the wrong count is the same as that of the correct count The predetermined difference of the weights of the weights is 0.1, then the weight of the calibration type corresponding to the object sample Bj corresponding to the prompt information sample Ai should be -0.6.

Assume that the object sample Bj corresponds to the weight of the correct count Q1=0.6, the weight of the wrong count Q2=0.4, and the weight of the calibration type corresponding to the prompt information sample Ai, and the weight of the correct count is equal to the weight of the wrong count If the predetermined difference is 0.1, then the weight of the calibration type of the object sample Bj corresponding to the prompt information sample Ai should be 0.6.

Through the above modification to the weight value Ci,j of the calibration type, the weight value of the calibration type of the target sample can be made more accurate, thereby making the calculation of the verification passing value T0 more accurate.

In the technical solution provided by this embodiment, the server sends the verification code to the user terminal, and the user terminal returns the information of the selected object to the server according to the user's selection of the object, and the server calculates the verification pass value T0 according to the information of the selected object and predetermined rules , and then by comparing the verification pass value T0 with the preset first threshold T1 to determine whether the verification result is passed, further, the server also compares the verification pass value T0 with the fourth threshold T4, if the verification pass value T0 exceeds the fourth threshold T4 , according to the selection of the object by the user, correct the calibration type of the object sample corresponding to the current prompt information, realize the automatic correction of the calibration type of the current object sample, and improve the efficiency.
