Description

Technical Field

[0002] With the development of Internet technology, information security has become a very important issue. Among them, user identity security is of utmost importance.

[0003] Currently, graphical and textual methods are usually used for user security verification to ensure user identity security. For example, when a user conducts verification, a picture containing multiple numbers is randomly selected and displayed on the verification page. The user needs to enter the numbers in the picture to pass the verification. Or when a user conducts verification, a word is randomly selected, scrambled and placed in a background picture, and then displayed on the verification page. The user needs to enter the word in the correct order to pass the verification.

[0004] However, the cracking difficulty of the above verification methods is relatively low, and it is easy for machines to recognize the correct verification method, resulting in low system security. Summary of the Invention

[0078] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0079] It should be understood that "an embodiment" or "an embodiment" mentioned throughout the specification means that a specific feature, structure, or characteristic related to the embodiment is included in at least one embodiment of the present invention. Therefore, the appearances of "in an embodiment" or "in an embodiment" throughout the specification do not necessarily refer to the same embodiment. In addition, these specific features, structures, or characteristics can be combined in any suitable manner in one or more embodiments.

[0080] In various embodiments of the present invention, it should be understood that the sequence numbers of the following processes do not mean the order of execution is prior or posterior, and the execution order of each process should be determined by its function and internal logic, and should not constitute any limitation to the implementation process of the embodiments of the present invention.

[0081] See Figure 1 , an embodiment of the present invention provides a verification method applied to a server, and the method includes:

[0082] Step 101: Receive a first verification request carrying a target keyword sent by a terminal device.

[0083] It should be noted that the target keyword can be a word or a phrase, which can be related to the page content of the current display page of the terminal device. It can be understood that the first verification request carries target data, and the target data can be the target keyword itself or an image containing the target keyword. In the case where the target data is an image containing the target keyword, the image will be recognized to parse out the target keyword therein. Among them, OCR (Optical Character Recognition) technology can be used to parse the target keyword in the image, but it is not limited thereto.

[0084] Here, when the server receives the first verification request, it will start a verification process to verify the user on the terminal device side. Preferably, the verification here is used to detect whether the user on the terminal device side is a machine or a person, that is to say, whether the behavior of initiating this verification is a human operation or a malicious attack from a machine.

[0085] Step 102: Obtain the target questions containing the target keyword in the target database and the set of target answers corresponding to the target questions.

[0086] It should be noted that when verifying in the form of a combination of questions and answers, in order to avoid a high repetition rate of the questions provided to the user, the target database will pre-store a large number of questions and answers. In addition, for each question, multiple different answers need to be provided, including the correct answer and at least one wrong answer. Therefore, each question in the target database corresponds to a set of answers composed of the correct answer to this question and at least one wrong answer. Here, in order to make the questions provided to the user associated with the terminal device side, the questions matching the target keyword will be queried from the target database based on the target keyword, and the target questions containing the target keyword will be used as the successfully matched questions. Then, the set of target answers should be a set composed of the first answer that correctly answers the target question and at least one second answer that wrongly answers the target question. When the target keyword is related to the page content of the current display page of the terminal device, the questions provided to the user will be associated with the page content of the current display page of the terminal device side.

[0087] It can be understood that in order to quickly query the required questions or answers in the target database, the questions and answers can be stored separately. Therefore, the target database can include a preset question library and a preset answer library, which are not limited here.

[0088] It is understandable that the number of problems containing the target keyword in the target database can be one or more. In the case where the number is more than one, one of them can be selected as the target problem based on a preset policy. Among them, the preset policy can be the first policy of randomly selecting a problem as the target problem, or the second policy of selecting the problem with the largest weight as the target problem based on the weight of each problem, or the third policy of selecting the problem with the highest relevance to the target keyword as the target problem, but it is not limited to this.

[0089] Regarding the weight of each problem in the second policy, the same weight can be assigned to each problem initially. For each problem, as the number of times the problem is selected as the target problem increases, its weight continuously decreases. For example, "What is Li Bai's courtesy name?" is problem 1, and "Which dynasty's poet is Li Bai?" is problem 2. The initial weights of both problems are 1. At this time, if both problem 1 and problem 2 are problems containing the target keyword, the possibility of selecting problem 1 or problem 2 as the target problem is the same. During multiple verifications, as the number of times problem 1 is selected as the target problem increases, the weight of problem 1 will gradually decrease, so that the weight of problem 1 will be less than the weight of problem 2. When verifying again, if both problem 1 and problem 2 are problems containing the target keyword, problem 2 will be selected as the target problem. By selecting the target problem through the second policy, it is possible to avoid providing the same problem to the user to a greater extent, thereby reducing the repetition rate of the problems provided to the user.

[0090] Step 103: In the target answer set, process each answer according to a preset obfuscation policy to obtain an obfuscated answer set.

[0091] It should be noted that each answer in the target answer set has a certain correlation with the target problem. If the answer is directly displayed without any change, the machine can easily identify the correct answer based on these correlation relationships. Therefore, in order to avoid the machine from identifying the correct answer, the answer can be changed to a certain extent to increase the difficulty of identifying the answer, so that the machine is not easy to identify the correct answer, that is, the server processes each answer according to a preset obfuscation policy to obtain an obfuscated answer set that is not easily recognized by the machine. Among them, the preset obfuscation policy is a change rule that is preset for changing the answer and causing a certain degree of confusion. It is understandable that the obfuscated answer set is composed of answers with obfuscation effects, and each answer with an obfuscation effect corresponds to an answer in the target answer set.

[0092] Step 104: Send the target problem and the obfuscated answer set to the terminal device so that the terminal device displays the target problem and the obfuscated answer set on the verification page.

[0093] It should be noted that the target question and the set of confusing answers are the verification information to be shown to the user. Therefore, the target question and the set of confusing answers are sent to the terminal device, and the terminal device shows the verification information to the user.

[0094] Step 105: When receiving a second verification request for the target question sent by the terminal device, verify the answer to be verified carried in the second verification request based on the set of confusing answers.

[0095] It should be noted that the answer to be verified is the answer selected by the user from the set of confusing answers displayed on the terminal device. Therefore, by comparing the set of confusing answers with the answer to be verified, it can be determined whether the answer to be verified corresponds to the first answer for correctly answering the target question, thereby determining whether the verification is passed on the terminal device side. Specifically, when the answer to be verified is consistent with the answer obtained by processing the first answer according to the preset confusion strategy, it indicates that the answer to be verified corresponds to the first answer for correctly answering the target question, and the verification is passed. Otherwise, the verification fails.

[0096] In an embodiment of the present invention, the received first verification request carries a target keyword, so that the target keyword can be used to match the target question and the set of target answers corresponding to the target question in the target database. The set of target answers is a set composed of the first answer for correctly answering the target question and at least one second answer for incorrectly answering the target question. Furthermore, verification can be performed in the form of a combination of questions and answers, and the questions used for verification are related to the target keyword in the first verification request, which can avoid repeating the same question to the user to a greater extent. Then, each answer in the set of target answers is processed according to the preset confusion strategy to obtain a set of confusing answers that are not easily recognized by machines, and then the set of confusing answers is provided to the user. Finally, when receiving the second verification request, verify the answer to be verified carried in the second verification request based on the set of confusing answers. When the present invention provides verification in the form of a combination of questions and answers, the answers provided to the user are the answers processed according to the preset confusion strategy, making it more difficult for machines to identify the correct answers from them, thereby increasing the difficulty of machine cracking and enhancing the security of the system.

[0097] Optionally, the preset confusion strategy includes: a selection sub-strategy and a confusion sub-strategy. Processing each answer in the set of target answers according to the preset confusion strategy to obtain a set of confusing answers includes:

[0098] For each answer in the set of target answers, select multiple confusing characters corresponding to the answer in the preset confusion library according to the selection sub-strategy;

[0099] For each answer, combine the answer with its corresponding multiple obfuscation characters according to the obfuscation sub-strategy to generate the obfuscated answer corresponding to the answer;

[0100] Generate a set of obfuscated answers based on each obfuscated answer.

[0101] It should be noted that a large number of characters are pre-stored in the preset obfuscation library. In addition, the selection sub-strategy is a strategy for selecting multiple characters from a large number of characters as obfuscation characters. For example, the selection sub-strategy can be to randomly extract multiple characters from a large number of characters as obfuscation characters, but it is not limited to this. The obfuscation sub-strategy is a strategy for combining multiple obfuscation characters and an answer according to a certain combination rule. For example, the obfuscation sub-strategy can be to insert each character of the answer into different positions of the multiple obfuscation characters respectively to complete the combination, but it is not limited to this. For example, if the answer is "Li Bai" and the multiple obfuscation characters are "abcd123", the obfuscated answers corresponding to "Li Bai" can be "abLi cd1 Bai23", "abcdLi1 Bai23", or "aLi bcd1 Bai23".

[0102] In the embodiment of the present invention, through the selection sub-strategy and the obfuscation sub-strategy, the answer is obfuscated from two different aspects, making the obfuscated answer less likely to be recognized by a machine, and further improving the security of the system.

[0103] Optionally, combining the answer with its corresponding multiple obfuscation characters according to the obfuscation sub-strategy to generate the obfuscated answer corresponding to the answer includes:

[0104] Add the multiple obfuscation characters corresponding to the answer to the answer to generate an intermediate obfuscated answer;

[0105] Adjust the positions of the characters in the intermediate obfuscated answer in the intermediate obfuscated answer to generate the obfuscated answer corresponding to the answer.

[0106] It should be noted that when adding multiple obfuscating characters before and after the answer, the order of each character in the answer will not change, and the order of each obfuscating character among the multiple obfuscating characters will not change either. Therefore, to further increase the difficulty of cracking the obfuscated answer, by adjusting the positions of the characters in the intermediate obfuscated answer within the intermediate obfuscated answer, the order of each obfuscating character in the obfuscated answer is not necessarily the same as the order of each obfuscating character in the intermediate obfuscated answer, and the order of each character in the obfuscated answer is not necessarily the same as the order of each character in the intermediate obfuscated answer. It can be understood that the characters in the intermediate obfuscated answer here can be obfuscating characters or non-obfuscating characters in the answer. For example, a random strategy can be adopted to randomly adjust the order of each character in the intermediate obfuscated answer, but it is not limited to this. For example, if the intermediate obfuscated answer is "Li Bai 12343", the obfuscated answer can be "Bai 123 Li 43" or "43 Bai 1 Li 23". Preferably, adjusting the positions of the characters in the intermediate obfuscated answer within the intermediate obfuscated answer includes: reversing the order of multiple characters corresponding to the answer in the intermediate obfuscated answer. The reversed order here is other orders than the correct order, and the correct order is the order represented by the answer. For example, if the answer is "Bai Juyi", its reversed order can be "Bai Yiju", "Yiju Bai", "Yi Baiju", etc.

[0107] In the embodiment of the present invention, in the process of generating an obfuscated answer based on the answer and multiple obfuscating characters, the recognition difficulty of the obfuscated answer can be further increased by means of secondary obfuscation.

[0108] Optionally, the preset obfuscation library includes: multiple types of obfuscating characters;

[0109] Selecting multiple obfuscating characters corresponding to the answer according to the selection sub-strategy in the preset obfuscation library includes:

[0110] Sequentially selecting multiple obfuscating characters from the obfuscating characters of each type in the preset obfuscation library;

[0111] Determining the selected obfuscating characters of various types as multiple obfuscating characters corresponding to the answer.

[0112] It should be noted that the multiple obfuscation characters selected for each answer are of multiple types of obfuscation characters. Among them, the number of different types of obfuscation characters in the multiple obfuscation characters corresponding to the answer can be equal or unequal. Preferably, the number of obfuscation characters of each type is equal. The types of obfuscation characters include: multiple of the number type, letter type, punctuation type, and special symbol type. The obfuscation characters are used to combine with the answer to generate an obfuscated answer. It should be noted that compared with the answer, the obfuscated answer has a higher recognition difficulty. However, the meaning represented by the obfuscated answer remains unchanged. Only the answer is obfuscated to increase the recognition difficulty of the answer, but the semantic content of the answer will not be changed. The obfuscation characters of the number type are numbers, the obfuscation characters of the letter type are English letters, which can be capital letters, lowercase letters, etc., the obfuscation characters of the punctuation type are punctuation marks, which can be punctuation marks in Chinese or English, and the obfuscation characters of the special symbol type are special symbols. Specifically, the preset obfuscation library includes ten numbers from 0 to 9, twenty-six English letters from a to z, multiple punctuation marks in Chinese and English, and multiple special symbols.

[0113] In the embodiment of the present invention, the obfuscation characters corresponding to each answer can be selected from different types of obfuscation characters, thereby further increasing the recognition difficulty of the obfuscated answer.

[0114] Optionally, after adjusting the position of the text in the intermediate obfuscated answer to generate the obfuscated answer corresponding to the answer, the method further includes:

[0115] Create a first hash table and a second hash table;

[0116] For each answer, store the obfuscated answer corresponding to the answer and the identifier indicating whether the answer is the first answer as a key-value pair in the first hash table;

[0117] Store the target question and the first hash table as a key-value pair in the second hash table;

[0118] Verify based on the obfuscated answer set and the answer to be verified carried in the second verification request, including:

[0119] Determine the first hash table corresponding to the target question in the second hash table;

[0120] Based on the answer to be verified, determine the target answer in the first hash table, where the target answer is the obfuscated answer identical to the answer to be verified;

[0121] Generate a verification result based on the identifier corresponding to the target answer in the first hash table.

[0122] It should be noted that a hash table is a data structure that implements the abstract data type of an associative array. This structure can set the key and the given value as a set of key-value pairs, providing a mapping relationship that maps the key to the given value, simply referred to as a hash table (hashmap). Here, in the first hash table, the key is the obfuscated answer corresponding to the answer, and the given value is the identifier indicating whether the answer is the first answer; in the second hash table, the key is the target question, and the given value is the first hash table. It can be understood that the answer to be verified is the answer selected by the user from the set of obfuscated answers displayed on the terminal device. Therefore, by comparing the set of obfuscated answers with the answer to be verified, it can be determined whether the answer to be verified corresponds to the first answer for correctly answering the target question, thereby determining whether the verification is passed on the terminal device side. Specifically, when receiving the second verification request for the target question sent by the terminal device, the first hash table corresponding to the target question can be determined in the second hash table, that is, in the second hash table, find the key-value pair with the target question as the key, and then the given value in this key-value pair is the first hash table corresponding to the target question. Then, in the first hash table, find the obfuscated answer that is the same as the answer to be verified, and finally, determine the verification result according to the given value mapped by this obfuscated answer.

[0123] Here, taking the target question "Which dynasty was Du Fu a poet of?" as an example, the first hash table and the second hash table are shown. The data structure is as follows:

[0124] The first hash table is {"aa-! Chao z = Tang bz", true}, {"at-! Chao z = Yuan ba", false}, {"ca-! Song z = 4z", false}, {"ab-! Chao z = Tang bz", false}, where parts such as "aa-! Chao z = Tang bz" and "Chao z = Yuan ba" are the key parts of the first hash table, that is, the set of obfuscated answers; parts such as "true" and "false" are the given value parts of the first hash table, that is, the identifier indicating whether the answer is the first answer. Among them, "true" indicates that this answer corresponds to the first answer for correctly answering the target question; "false" indicates that this answer corresponds to the second answer for wrongly answering the target question.

[0125] The second hash table is {"Which dynasty was the poet Du Fu from?": [{"aa-! Dynasty z = Tang bz", true}, {"at-! Dynasty z = Yuan ba", false}, {"ca-! Dynasty z = Song 4z", false}, {"ab-! Dynasty z = Tang bz", false}]}, where the "Which dynasty was the poet Du Fu from?" part is the key part of the second hash table, that is, the target question part, and [{"aa-! Dynasty z = Tang bz", true}, {"at-! Dynasty z = Yuan ba", false}, {"ca-! Dynasty z = Song 4z", false}, {"ab-! Dynasty z = Tang bz", false}] is the given value part of the second hash table, that is, the first hash table part.

[0126] If the answer to be verified is "ab-! Dynasty z = Tang bz", according to the target question "Which dynasty was the poet Du Fu from?", the first hash table can be determined from the second hash table first, and then in the "{ab-! Dynasty z = Tang bz", false} in the first hash table, it can be determined that "ab-! Dynasty z = Tang bz" corresponds to "false", then a verification result of verification failure or verification not passed is generated. Similarly, if the answer to be verified is "aa-! Dynasty z = Tang bz", then it can be determined that "aa-! Dynasty z = Tang bz" corresponds to "true", and a verification result of verification passed is generated.

[0127] In the embodiment of the present invention, the two-layer nested hash table is used to store the target question and the set of confused answers required for verification, and the verification of the answer to be verified can be quickly completed, thereby improving the verification efficiency.

[0128] See Figure 2 , the embodiment of the present invention provides a verification method, which is applied to a terminal device, and the method includes:

[0129] Step 201: Obtain a target image including the page content of the current display page.

[0130] It should be noted that the target image includes the page content of the current display page on the terminal device side. Among them, the page content can be a certain frame of a video being played or a certain picture, and there is no limit here. Here, there are various ways to obtain the target image. For example, the target image can be obtained by randomly taking a screenshot of a certain position of the current display page, but it is not limited to this.

[0131] Step 202: Generate a target keyword based on the target image.

[0132] It should be noted that the generated target keywords can exist in any data form. For example, they can exist in the form of text or in the form of images. For example, the target keyword in text form can be "Li Bai", or it can be an image containing the text "Li Bai". It can be understood that when the target keyword exists in the form of an image, the target keyword can be a partial image containing text information in the target image or the target image itself.

[0133] Step 203: Send a first verification request carrying the target keyword to the server, so that the server returns the target question and the set of confusing answers based on the target question containing the target keyword in the target database and the set of target answers corresponding to the target question.

[0134] It should be noted that when the terminal device sends a first verification request carrying the target keyword to the server, it indicates that the user has a verification requirement, and the target keyword is information related to the page content of the current display page of the terminal device. So that when the server receives the first verification request, it will start the verification process to verify the user on the terminal device side, and the questions used for verification are related to the page content of the current display page on the terminal device side. It can be understood that the process of the server returning the target question and the set of confusing answers based on the target question containing the target keyword in the target database and the set of target answers corresponding to the target question can refer to the above-mentioned invention embodiments. To avoid repetition, it will not be elaborated here.

[0135] Step 204: Receive the target question and the set of confusing answers.

[0136] Step 205: Display a verification page and display the target question and the set of confusing answers on the verification page.

[0137] It should be noted that the target question and the set of confusing answers are the verification information that needs to be shown to the user. Therefore, when receiving the target question and the set of confusing answers, display the verification page and show the verification information to the user.

[0138] Step 206: When receiving the target input of the user for the answer to be verified, send a second verification request carrying the answer to be verified to the server for the target question, so that the server verifies the answer to be verified carried in the second verification request based on the set of confusing answers.

[0139] It should be noted that after showing the verification information to the user, the terminal device needs to receive the target input of the user, that is, the terminal device receives the answer to be verified selected by the user, adds the answer to be verified to the second verification request, and sends the second verification request to the server so that the server performs the verification operation. Here, the answer to be verified is any element in the set of confusing answers displayed on the verification page.

[0140] In an embodiment of the present invention, a target image containing the page content of the currently displayed page is first obtained, and a target keyword is generated based on the target image, and then a first verification request carrying the target keyword is sent to the server, so that the server returns the target question and the obfuscated answer set based on the target question containing the target keyword and the target answer set corresponding to the target question in the target database, so that the target question and the obfuscated answer set can be provided to the user for verification in a combination of questions and answers, and the question used for verification is related to the target keyword in the first verification request, which can avoid repeatedly providing the same question to the user to a greater extent. After that, a verification page is displayed, and the target question and the obfuscated answer set are displayed in the verification page; finally, when the user receives the target input for the answer to be verified, a second verification request carrying the answer to be verified is sent to the server for the target question, so that the server verifies the answer to be verified carried in the second verification request based on the obfuscated answer set. In the present invention, when verification is provided in a combination of questions and answers, the answer provided to the user is an obfuscated answer, which makes it more difficult for the machine to identify the correct answer, thereby increasing the difficulty of machine cracking and improving the security of the system. At the same time, the target questions required for verification are related to the page content of the page currently displayed by the terminal device, which can avoid repeatedly providing the same questions to the user to a greater extent, thereby reducing the repetition rate of the questions provided to the user.

[0141] See also Figure 3 , an embodiment of the present invention provides a flow chart of a verification method, the flow chart comprising:

[0142] Step 301: Capture any image on the current system browsing page and generate source content.

[0143] It should be noted that any picture on the current system browsing page includes but is not limited to part or all of the pictures on the browsing page. In other words, part of the pictures on the current system browsing page can be intercepted to generate the source content, or all of the pictures on the current system browsing page can be intercepted to generate the source content, and there is no limitation here. It can be understood that the intercepted pictures here are Figure 2 The target images in the illustrated embodiment are similar and will not be described in detail here.

[0144] Step 302: Analyze the image and identify valid content.

[0145] It should be noted that the image parsing here refers to the intercepted image mentioned in the above step 301, and the effective content recognition refers to identifying text information from the information contained in the intercepted image, and determining part or all of the text information in the text information as effective content. The effective content here is the same as Figure 1The target keywords in the illustrated embodiments are similar and will not be elaborated here.

[0146] Step 303: Use the valid content to perform a relevance collision with the local question bank.

[0147] It should be noted that the so-called relevance collision means querying for questions containing the valid content in the local question bank based on the valid content.

[0148] Step 304: Are there any matching items?

[0149] It should be noted that if there are matching items, it can indicate that there are questions containing the valid content and the corresponding answer set in the local question bank. Therefore, execute Step 305; if there are no matching items, it means that questions containing the valid content cannot be found in the local question bank. At this time, Step 306 will be executed.

[0150] Step 305: Generate questions and related answers.

[0151] It should be noted that generating questions and related answers here is equivalent to Figure 1 obtaining the target answers and the target answer set in the illustrated embodiments and will not be elaborated here.

[0152] Step 306: Obtain a random difficulty coefficient.

[0153] Step 307: Randomly obtain questions and answers from the local question bank according to the difficulty coefficient.

[0154] It should be noted that different random difficulty coefficients correspond to questions of different difficulty levels in the local question bank. When obtaining questions and answers based on a certain random difficulty coefficient, questions will be obtained from the questions of the difficulty level corresponding to the random difficulty coefficient. Then, obtain the answer set corresponding to the question in the local answer bank.

[0155] Step 308: Answer obfuscation.

[0156] It should be noted that in order to increase the difficulty of identifying answers, making it difficult for the system to identify the correct answers and thus enhancing the security of the system, the system needs to process the answers and cause a certain degree of obfuscation. Here, obfuscation characters can be added to the answers to make the answers become obfuscated answers. The obfuscation characters here can be numbers 1-9, or letters a-z, or special symbols, or punctuation marks, etc., and are not limited here.

[0157] Step 309: Secondary obfuscation, perform transposition.

[0158] It should be noted that the secondary obfuscation is also carried out on the answer. The purpose is the same as that of the primary obfuscation, which is to increase the recognition difficulty of the answer, thereby enhancing the security of the system. Here, the secondary obfuscation is mainly a transposition operation, that is, adjusting the positions of the characters in the answer and / or adjusting the positions of the obfuscation characters in the obfuscated answer. For example, if the answer is "Tang Dynasty" and the obfuscation characters are "abcd123", the obfuscated answer can be "Tang ab1 Dynasty 23cd", or "12 Dynasty cd Tang ab3", etc.

[0159] Step 310: Generate questions and obfuscated answers.

[0160] In the embodiment of the present invention, first, an arbitrary picture on the current system browsing page is intercepted to generate source content; then the picture is parsed to identify the valid content, so as to obtain the valid content related to the question; then this content is used to perform a relevance collision with the local question bank to determine whether there is a matching item, and then generate questions and related answers; then the answer is obfuscated twice, and finally questions and obfuscated answers are generated, thereby increasing the recognition difficulty of the answer, making it difficult for the system to identify the correct answer, and thus enhancing the security of the system.

[0161] See Figure 4 , the embodiment of the present invention provides a schematic diagram of the data processing process of a verification method, and the process includes:

[0162] Step 401: The front end intercepts the picture on the current browsing page.

[0163] It should be noted that the front end here is equivalent to the Figure 2 terminal device in the embodiment shown, which will not be elaborated here.

[0164] Step 402: Convert the picture to 64 bits and transfer it to the back end.

[0165] It should be noted that the back end here is equivalent to the Figure 1 server in the embodiment shown, which will not be elaborated here. It should be known that since the information space occupied by pictures and other information is too large, during the information transmission process, the transmitted is the information flow containing picture information, rather than the picture information itself. Therefore, the picture is converted to 64-bit information here and then transferred to the back end.

[0166] Step 403: Call the OCR algorithm to identify the picture content.

[0167] It should be noted that the OCR algorithm is an algorithm for identifying image text. Therefore, calling this algorithm to identify the picture content is to obtain the text content in the picture.

[0168] Step 404: Perform relevance matching in the search server based on the recognized text content, and select the one with a higher score and its related answers.

[0169] It should be noted that when the search server performs relevance matching, each question found will be scored. That is to say, as the degree of association with the recognized text content increases, its score also increases. Here, select the question with a higher score and its related answers.

[0170] Step 405: Add irrelevant letters and numbers to the answer to achieve an obfuscation effect.

[0171] Step 406: Perform another transposition obfuscation on the obfuscated answer.

[0172] Step 407: Package the question object.

[0173] It should be noted that the object is a function of a specific program in a computer language. Here, the question object is a function that combines the question and the answer after re-obfuscation. It is convenient for the server to send it to the terminal device.

[0174] Step 408: Create a hash table to store the answer, with the answer as the key and a flag indicating whether it is correct or incorrect as the value.

[0175] It should be noted that a hash table (abbreviated as hash table) can represent a mapping relationship of a set of key-value pairs. Among them, the key is key and the value is value. Here, create a hash table to store the answer. In this hash table, the key is the answer, and the value is a flag indicating whether the answer is correct. Among them, the flag for correct is true; the flag for incorrect is false.

[0176] Step 409: Establish a hash table with the question as the key and the hash table of the answer as the value, forming a cascaded hash table.

[0177] It should be noted that when establishing a hash table for the question, the key is the question and the value is the hash table of the answer. In a situation where the key or value in such a hash table is another hash table, we call it a cascaded hash table.

[0178] Step 410: Store it in the database, with the key being the current user identifier + question identifier, the value being the cascaded hash table, and set an expiration time.

[0179] It should be noted that the user identifier here is the user identifier of the currently verified user, and the question identifier is the identifier of the target question, which can be the target question itself, but is not limited to this. For example, during the verification process when user A logs in to his own account, the user identifier is the account name of user A, and the question identifier is the target question.

[0180] Step 411: Return the currently generated question object.

[0181] It should be noted that the backend returns the question object containing the question and the re-confused answer to the frontend, so that the frontend can display the corresponding data for the user to select. After the user makes a selection, the backend will receive the verification request carrying the answer to be verified sent by the frontend and initiate the verification process. Among them, the steps to be executed after the backend initiates the verification process are as Figure 5 shown, including:

[0182] Step 501: Assemble the current question identifier and the user identifier into a database key.

[0183] It should be noted that the verification request carries the question identifier representing the current question and the user identifier of the current user. Since the key in Step 410 is the current user identifier + question identifier and the value is the cascaded hash table, by assembling the current question identifier and the user identifier, a key can be obtained, and the cascaded hash table required for verification is the value corresponding to this key.

[0184] Step 502: Obtain the current question cascaded hash table.

[0185] Step 503: Obtain the hash table of the answer according to the current question.

[0186] Step 504: Pass in the answer to obtain the identification value in the answer hash table. If it is not correct, this verification fails.

[0187] It can be understood that the process of using the cascaded hash table for verification is similar to the process of verification based on the first hash table and the second hash table in the foregoing invention embodiments, and will not be elaborated here.

[0188] See Figure 6 , this invention embodiment provides a verification device applied to a server. The device includes:

[0189] The first receiving module 61 is configured to receive the first verification request carrying the target keyword sent by the terminal device;

Finally, when receiving the second verification request, the answer to be verified carried in the second verification request is verified based on the set of confused answers. In the case where the present invention provides verification in a combined manner of questions and answers, the answers provided to the user are the answers after being subjected to confusion processing according to the preset confusion strategy, making it more difficult for the machine to recognize the correct answer from them, thereby increasing the difficulty of machine cracking and enhancing the security of the system.

[0211] See Figure 7 , an embodiment of the present invention provides a verification device, which is applied to a terminal device. The device includes:

[0218] In the embodiment of the present invention, first, a target image containing the page content of the current display page is obtained, and based on the target image, a target keyword is generated. Then, a first verification request carrying the target keyword is sent to the server, so that the server returns the target question and the set of confusing answers based on the target question containing the target keyword in the target database and the set of target answers corresponding to the target question, and thus can be provided to the user for verification in the form of a combination of questions and answers. Moreover, the questions used for verification are related to the target keyword in the first verification request, which can avoid providing the same questions to the user repeatedly to a greater extent. Then, the verification page is displayed, and the target question and the set of confusing answers are displayed on the verification page. Finally, when receiving the target input of the user for the answer to be verified, a second verification request carrying the answer to be verified is sent to the server for the target question, so that the server verifies the answer to be verified carried in the second verification request based on the set of confusing answers. When the present invention provides verification in the form of a combination of questions and answers, the answers provided to the user are answers after being obfuscated, making it more difficult for the machine to identify the correct answer therefrom, thereby increasing the difficulty of machine cracking and enhancing the security of the system.
