Technical field

The present specification relates to the field of Internet technologies, and in particular, to a method and an apparatus for generating a verification questionnaire.

Background technique

To ensure the security of the Internet business, verification issues can be used to verify the identity of the user. The current verification problem usually has two sources. One is user pre-set, such as "What is the name of your high school class teacher?", etc. This verification problem is less memorable, resulting in poor usability. The other is that the background automatically generates verification questions based on the user's historical data, such as "choose the products you have purchased", etc. However, this method relies on rich historical data and has a small scope of application. Therefore, it is necessary to provide a verification problem generation scheme with high availability and wide application range.

Detailed ways

Exemplary embodiments will be described in detail herein, examples of which are illustrated in the accompanying drawings. The following description refers to the same or similar elements in the different figures unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present specification. Instead, they are merely examples of devices and methods consistent with aspects of the present specification as detailed in the appended claims.

The terminology used in the description is for the purpose of describing particular embodiments, and is not intended to The singular forms "a", "the" and "the" It should also be understood that the term "and/or" as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items.

It should be understood that although the terms first, second, third, etc. may be used in this specification to describe various information, such information should not be limited to these terms. These terms are only used to distinguish the same type of information from each other. For example, the first information may also be referred to as the second information without departing from the scope of the present description. Similarly, the second information may also be referred to as the first information. Depending on the context, the word "if" as used herein may be interpreted as "when" or "when" or "in response to a determination."

Referring to FIG. 1, the method for generating the verification questionnaire can be applied to an electronic device such as a terminal or a server, and includes the following steps:

Step 102: Transform the available verification question into a supplementary verification question when the predetermined condition is triggered.

In this embodiment, the available verification question includes a verification question set by the user, for example: "What is the name of your high school class teacher?", "What is your favorite book?" The available verification questions may also include verification questions that are automatically generated based on historical data of the user, such as: "select the products you have purchased", "select the restaurants you have visited", and the like.

In this embodiment, the modification of the available verification problem can be implemented by modifying the answer option corresponding to the specified type by modifying the answer type of the specified type of available verification question. For example, you can modify any of the wrong answer options for available verification questions to answer options such as "None of the above" and "Not correct above."

In this embodiment, for convenience of description, the modified available verification problem may be referred to as a supplementary verification question; the answer option that is different from the available verification question before the modification may be referred to as a modification option, that is, The answer option of "The above is not" and "The above is not correct" can be referred to as a transformation option.

Step 104: Determine the number of requirements for verifying the question in the verification questionnaire output to the target user.

In this embodiment, the demand quantity is usually positively related to the security level of the verification questionnaire, and the higher the security level, the higher the number of requirements is usually.

Step 106: Determine whether the number of available verification questions corresponding to the target user is greater than or equal to the required quantity.

Step 108: When the number of available verification questions is greater than or equal to the required quantity, extract a verification question in the available verification question of the target user to generate a verification questionnaire.

Step 110: When the number of available verification questions is less than the required quantity, extract a verification question in the supplementary verification question and the available verification question of the target user to generate a verification questionnaire.

The following describes the specific implementation process of the specification from three aspects: the modification of the available verification problem, the determination of the randomness of the modification option, and the generation of the verification questionnaire.

First, the transformation of available verification problems

In this embodiment, the available verification question can be modified to supplement the verification question when the predetermined condition is triggered.

The predetermined condition is usually set by the developer, and may be triggered during the process of generating the verification questionnaire for the target user. This specification will introduce the situation in which the predetermined condition is triggered later.

In this embodiment, in the process of generating a verification questionnaire for the target user, if the predetermined condition is triggered, the available verification question of the target user may be transformed into a supplementary verification question.

In one example, several available verification questions may be extracted from all available verification questions of the target user, and then the extracted available verification questions are transformed into supplementary verification questions. For example, a predetermined number of available verification questions may be randomly selected from all the verification questions of the target user, and the predetermined number may be 1 or other values greater than 1. This embodiment does not specifically limit this.

In another example, to improve the usability of the supplemental verification problem after the transformation, you can first select the available verification questions with low difficulty and large answer option space from all available verification questions of the target user, and then from these available verification questions. Extract a number of available verification questions for retrofitting.

For example, the verification questions "Choose the items you bought" and "Choose the restaurants you have been to" are usually available verification questions with less difficulty and a larger answer option space. Conversely, “What is the name of your high school class teacher?” is a more difficult verification question. “Choose the city you have been to” is a valid verification question with a small option space. For example, many people have been there. In major cities such as Beijing, Shanghai, and Shenzhen, such verification problems are not suitable for transformation.

In this embodiment, when the available verification problem is modified, the answer option of the specified type of the available verification question can be modified to the modification option corresponding to the specified type. Among them, the answer options of the specified type usually include: the correct answer option and the wrong answer option.

For example, if the answer option of the specified type is the wrong answer option, the corresponding modification option may include a modification option such as “the above is not” and “the above is not correct”. When making a transformation, you can modify any of the wrong answer options for the available verification questions to "None of the above" or "The above is not correct" to implement the transformation.

For example, suppose an available verification question (question 1) is

"Choose the goods you bought"

A, Spalding basketball

B, XX brand dress

C, children's remote control car

D, XX brand maternity dress

For the target user, the correct option for this available verification question is A Spalding Basketball. When making a transformation, the answer option B, C, or D of the available verification question can be modified to "None of the above." For example, the following verification problem can be obtained after the modification (question 2)

"Choose the goods you bought"

A, Spalding basketball

B, XX brand dress

C, children's remote control car

D, none of the above

In this embodiment, after the modification problem of the target user is modified, the verification problem after the modification can be obtained.

On the one hand, the available verification problem before the transformation can be replaced by the modified verification problem to update the available verification problem of the target user, that is, the verification verification problem is a new available verification problem of the target user. Still taking the aforementioned questions 1 and 2 as an example, question 2 can be used to replace question 1 as the available verification question for the target user. For the target user, the answer to the new available verification question is still A Spalding basketball.

On the other hand, the modified verification problem can also be used as a supplementary verification question for non-target users, so that when the available verification questions of the non-target users are insufficient, the supplementary verification questions are extracted to generate a verification questionnaire. Still taking question 2 as an example, for non-target users, the answer to the supplementary verification question is not D or above.

In other words, the post-retrofit verification problem has two identities, one is the new available verification question for the target user, and the other is the supplementary verification problem for the non-target user. In practical applications, the verification problems of different identities may be separately stored, or the special verification marks may be used to distinguish the supplementary verification problems, and the specification does not specifically limit this.

In this embodiment, when the available verification problem is modified, any correct answer option of the available verification question may be modified to "all of the above" and "all of the above are correct", etc. The embodiments are not described herein again.

Second, the transformation option randomness

In this embodiment, as an example of modifying the answer option of any error of the available verification question to the "nothing above", the modified verification question is not a modification option for the target user, For non-target users, the correct option is the retrofit option.

To ensure that the retrofit option is the correct option or the randomness of the wrong option, this specification introduces a randomness reference factor for the retrofit option, which can be achieved by updating the random reference factor value of the retrofit option. For example, the value of the randomness reference factor of the retrofit option is maintained within a predetermined range to ensure randomness of the retrofit options.

The update of the above random reference factor values will be described in detail in the subsequent embodiments.

Third, the verification questionnaire generation

Referring to FIG. 2, the generation of the verification questionnaire in this embodiment may include the following steps:

Step 202: Determine the number of requirements for verifying the question in the verification questionnaire output to the target user.

In this embodiment, when the target user performs operations such as password recovery, password modification, payment, etc., which require a higher security level, the verification questionnaire may be output to the target user to verify the identity of the target user.

In this embodiment, for convenience of description, the number of verification questions in the verification questionnaire may be referred to as the quantity of demand, and the quantity of the requirements is usually positively related to the security level. The higher the security level, the more the number of requirements is usually. For the processing and implementation, reference may be made to related technologies, and the description is not repeated herein.

Step 204: Obtain the number of available verification questions corresponding to the target user.

In this embodiment, the number of available verification questions corresponding to the target user can be obtained. For example, find the corresponding available verification question based on the identity of the target user and count the number of available verification questions found.

In this embodiment, the available verification problem may include a verification problem set by the target user, and may also include a verification problem automatically generated by the target user according to the historical data of the target user, which is not specifically limited in this embodiment.

Step 206: Obtain a value of a random reference factor of the transformation option.

In this embodiment, the value of the randomness reference factor of the retrofit option may be stored at a predetermined location, and the initial value may be a predetermined value. The value of the randomness reference factor may be obtained from the predetermined location before the verification questionnaire is generated for the target user. After the verification questionnaire is generated for the target user, the random reference factor may be updated according to the modification option in the verification questionnaire. The value.

It should be noted that the embodiment does not limit the execution sequence of the foregoing steps 202-206. In another example, step 204 or step 206 may also be performed first, and the specification does not specifically limit this. After obtaining the quantity of the above requirement, the number of available verification questions corresponding to the target user, and the value of the randomness reference factor, the quantity of the requirement and the number of available verification questions corresponding to the target user may be compared, and the value of the random reference factor is compared. And the size of the predetermined threshold, and then the generation strategy of the verification questionnaire is determined according to the comparison result.

Step 208: When the number of available verification questions is greater than or equal to the required quantity, and the value of the randomness reference factor of the transformation option is greater than or equal to the first threshold, the verification question is extracted from the available verification questions of the target user to generate a verification questionnaire.

In this embodiment, if the modification option is “none is not”, if the number of available verification questions of the target user is greater than or equal to the required quantity, and the value of the random reference factor of the transformation option is greater than or equal to the first threshold, Usually, the number of available verification questions for the target user is sufficient, but the probability that the modification option "None of the above" is the wrong option is large. To continue to increase the probability that "the above is not" is the wrong option, there is no need to modify the available verification problem. The verification question may be extracted from the available verification questions corresponding to the target user to generate a verification questionnaire, for example, randomly extracting the required number of available verification questions to generate a verification questionnaire.

Step 210: When the number of available verification questions is greater than or equal to the required quantity, and the value of the randomness reference factor of the transformation option is less than the first threshold, determining that the predetermined condition is triggered.

In this embodiment, when the number of available verification questions of the target user is greater than or equal to the required quantity, and the value of the random reference factor of the transformation option is less than the first threshold, the number of available verification questions of the target user is generally sufficient, and the modification option is The randomness does not exceed the first threshold (which can be understood as a peak), and it can be determined that the predetermined condition is triggered, and then step 212 is performed to perform the modification of the available verification problem to increase the reserve of the supplementary verification problem.

Step 212, transforming the available verification question of the target user into a supplementary verification question.

In this embodiment, a number of available verification problems may be randomly selected from the available verification problems of the target user and modified. The method for the modification may refer to the foregoing embodiments, and the description is not repeated herein.

In this embodiment, the verification problem obtained after the modification of the available verification problem is replaced with the available verification problem before the transformation as a new available verification problem for the target user, for example, the identity of the target user is still maintained and Verify the correspondence of the problem.

On the other hand, the verification problem obtained after the modification is still a supplementary verification problem of the non-target user. For example, a special mark is added for the verification problem to distinguish, and the like, and the details are not described herein again.

Step 214: Extract a verification question from the available verification questions of the target user to generate a verification questionnaire.

Based on the foregoing step 212, after the target user's available verification problem is modified, the available verification questions of the target user include the unmodified available verification problem, and the new verifiable problem after the transformation.

In this embodiment, the verification question may be randomly extracted from the above-mentioned available verification questions of the target user to generate a verification questionnaire. It can be understood that the verification questions in the verification questionnaire may include the unproven available verification questions, and may also include new available verification questions after the transformation.

Step 216: When the number of available verification questions is less than the required quantity, and the value of the randomness reference factor of the transformation option is greater than or equal to the second threshold, extracting the verification question in the supplementary verification question and the available verification problem of the target user to generate Verify the questionnaire.

In this embodiment, when the number of available verification questions of the target user is less than the required quantity, and the value of the randomness reference factor of the transformation option is greater than or equal to the second threshold, it is generally stated that the number of available verification questions of the target user is insufficient to satisfy the verification. The number of requirements of the questionnaire, but the randomness of the transformation option is not lower than the second threshold (can be understood as the valley value), and then the verification problem can be randomly extracted in the supplementary verification problem and the available verification problem of the target user to generate verification. Questionnaire.

In this embodiment, the second threshold is smaller than the first threshold. For example, the value of the first threshold may be 100, and the value of the second threshold may be 0 or the like.

In another example, when the number of available verification questions of the target user is less than the required quantity and the value of the randomness reference factor of the transformation option is less than the second threshold, it is generally stated that the number of available verification questions of the target user is insufficient to satisfy the verification questionnaire. The number of requirements, and the modification option "None of the above" is the probability that the correct option is high, resulting in randomness imbalance, and may not be able to achieve the corresponding security level of authentication, so it is possible to output a message that the verification questionnaire cannot be generated.

Step 218, after outputting the generated verification questionnaire, determining whether there is a modification option in the verification questionnaire.

In this embodiment, after the verification questionnaire is generated for the target user, it may be determined whether there is a modification option in the verification questionnaire. If not, the current process may be ended; if yes, step 220 may be performed.

Step 220: When there is a modification option in the verification questionnaire, and the transformation option is the correct option, the value of the randomness reference factor of the current transformation option is subtracted from the first value.

In this embodiment, when there is a modification option in the verification questionnaire, an option category of the transformation option may be obtained, and if the transformation option is the correct option, the value of the random reference factor of the current transformation option may be subtracted from the first value. The value is updated to, for example, subtract 1 or the like, thereby reducing the value of the randomness reference factor, ie increasing the probability that the transformation option "none is not" is the correct option.

Step 222: When there is a modification option in the verification questionnaire, and the transformation option is an error option, the value of the random reference factor of the current transformation option is added to the second value.

In this embodiment, if the modification option in the verification questionnaire is an error option, the value of the random reference factor of the current transformation option may be added to the second value to be updated, thereby increasing the value of the random reference factor. That is, the corresponding increase in the transformation option "The above is not" is the probability of the wrong option.

The second value may be the reciprocal of the number of error options in the verification question in which the modification option is located.

For example, suppose the verification question has 6 answer options, the transformation option "Nothing above" is the wrong option, this verification question has 1 correct answer option, in addition to 4 wrong answers, that is, the verification problem is wrong. The number of options is 5, and the second value above is equal to 1/5.

Of course, in practical applications, other strategies may also be adopted to determine the value of the second value, which is not specifically limited in this specification.

It should be noted that if there are multiple transformation options in the verification questionnaire, for example, there are multiple verification problems, there may be a modification option, and the random reference factor value of the transformation option in the foregoing step 220 or 222 may be performed for each transformation option. Update operation.

As can be seen from the above description, when the predetermined condition is triggered, the present specification can transform the available verification problem into a supplementary verification question. If the available verification question corresponding to the target user is smaller than the required number of the verification questionnaire, the verification verification question and the target can be supplemented. The verification question is extracted from the user's available verification questions to generate a verification questionnaire, thereby ensuring that the verification questionnaire has sufficient verification problems, wide application range, and high availability. In addition, the randomness of the transformation options can be ensured by updating and judging the value of the random reference factor of the transformation option. Even if the illegal user attacks by illegal means such as reasoning, the correct option cannot be obtained, and the security of the verification problem is ensured. .
