Description

Technical Field

[0001] This invention relates to the field of information security technology or other related fields. Specifically, it relates to a method, apparatus, electronic device and storage medium for verifying batch verification codes. Background Technology

[0002] With the rapid development of the Internet, a large number of web pages and data information are generated. In order to ensure the security of related data and information, certain encryption and verification technologies are used to ensure data security. Among them, CAPTCHA is a common data verification method.

[0003] In related technologies, Figure 1 This is a schematic diagram of a verification method using CAPTCHA in existing technology, such as... Figure 1 As shown, the interaction flow between the front-end page and the back-end service includes:

[0004] (1) Generate verification code

[0005] The front-end page initiates a request to obtain a verification code. After receiving the verification code request from the front-end page, the back-end service randomly generates a verification code, stores the verification code in the cache with a certain type (e.g., String), and returns the cached key and the generated verification code to the front-end.

[0006] (2) Verify the verification code

[0007] After the frontend receives the verification code, it displays it on the frontend page in a certain format. After the user enters the verification information, a verification code verification request is initiated. The frontend sends the cached verification code key and the user-entered verification code to the backend. Upon receiving the request, the backend uses the verification code sent by the frontend to retrieve the previously generated verification code from the cache and compares it with the user-entered verification code sent by the frontend. If they match, the verification passes; otherwise, the verification fails.

[0008] (3) Re-obtain the verification code

[0009] When a verification code that cannot be clearly identified appears or the user needs to change the verification code, repeat step (1) to obtain the verification code and use step (2) to verify it.

[0010] The existing CAPTCHA verification method shown above has obvious drawbacks: it requires calling the backend service to regenerate the CAPTCHA every time it needs to be obtained again, resulting in frequent access to the backend interface.

[0011] There is currently no effective solution to the above problems. Summary of the Invention

[0043] To facilitate understanding of the present invention by those skilled in the art, some terms or nouns involved in the various embodiments of the present invention are explained below:

[0044] CAPTCHA: To prevent malicious page refreshing, brute-force login, etc., a public, fully automated program is provided to distinguish whether the operator is a computer or a natural person. It is generated and verified by a computer.

[0045] Redis, a remote dictionary service, is an open-source caching database that enables key-value, in-memory, or persistent storage services.

[0046] It should be noted that the batch verification method and apparatus of this disclosure can be used in the field of information security technology for identification and verification based on information security verification codes, and can also be used in any field other than information security technology for identification and verification based on information security verification codes.

[0049] The present invention will now be described in detail with reference to various embodiments.

[0050] Example 1

[0051] According to an embodiment of the present invention, an embodiment of a batch verification code verification method is provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0052] This invention provides a batch verification method for CAPTCHAs, which is applied to a front-end device used by a user and connected to a back-end server.

[0053] Figure 2 This is a flowchart of an optional batch verification method for a verification code according to an embodiment of the present invention, such as... Figure 2 As shown, the method includes the following steps:

[0054] Step S201: Obtain batch verification codes and store them in the front-end cache. The batch verification codes contain N verification codes to be used and each batch verification code corresponds to a batch keyword. The front-end devices include the front-end cache and the front-end screen interface, where N is an integer greater than or equal to 2.

[0055] Step S202: Extract the target verification code from the batch verification codes cached on the front end, and display the target verification code on the front end screen interface. The target verification code has an index value, which represents the extraction relationship of the target verification code from the batch verification codes.

[0056] Step S203: Receive user input information and send the batch keywords, the index value of the target verification code, and the user input information to the backend server. The user input information refers to the information generated by the user performing the verification operation on the front-end screen interface. The backend server queries the pre-cached target verification code based on the batch keywords and the index value, and compares the verification information in the user input information with the target verification code to obtain the verification result.

[0057] Step S204: Receive the verification result returned by the backend server.

[0058] Through the above steps, batch verification codes can be obtained during the verification process and stored in the front-end cache. The target verification code is extracted from the batch verification codes in the front-end cache and displayed on the front-end screen interface. Then, user input information is received, and the batch keywords, the index value of the target verification code, and the user input information are sent to the back-end server. The user input information refers to the information generated by the user performing the verification operation on the front-end screen interface. The back-end server queries the pre-cached target verification code based on the batch keywords and index value, compares the verification information in the user input information with the target verification code, obtains the verification result, and receives the verification result returned by the back-end server. In this embodiment, by generating verification codes in batches and returning them to the front-end device, when the front-end device re-obtains verification codes, it first traverses the batch verification codes. Only after traversing all the codes does it initiate the back-end service to re-generate verification codes in batches, reducing the frequency of back-end interface access. This solves the technical problem in related technologies where the back-end service needs to be called to regenerate verification codes every time a verification code is obtained, resulting in frequent access to the back-end interface.

[0059] The embodiments of the present invention will now be described in detail with reference to the steps described above.

[0060] It should be noted that this embodiment uses the user's front-end device as the execution subject for illustration. The types of front-end devices include, but are not limited to: mobile terminals (e.g., mobile phones, tablets, iPads, panel lights), PCs, desktop computers, financial terminals with operating screens, etc. The front-end device is connected to the back-end server.

[0061] In practical applications, this front-end device can also be used in other devices with touchscreens, such as vehicle displays and ATMs.

[0062] Optionally, before obtaining the batch verification codes, the process further includes: sending a verification code retrieval request to the backend server, wherein, after receiving the verification code retrieval request, the backend server randomly generates N image verification codes, combines the N image verification codes into a batch verification code, stores the batch verification code in a key-value pair cache, and generates a batch keyword and a verification code list corresponding to the batch verification code; and receiving the batch verification code, the batch keyword corresponding to the batch verification code, and the verification code list returned by the backend server.

[0063] This embodiment improves upon existing CAPTCHA technology by generating CAPTCHAs in batches. Upon receiving a CAPTCHA retrieval request, the backend server randomly generates N image CAPTCHAs (image verification). Alternatively, in the actual generation process, a batch of characters can be randomly generated based on the CAPTCHA retrieval request, and these characters will be used as the batch CAPTCHAs. The generated batch CAPTCHAs are stored in a cache using a specified storage format. For example, the batch CAPTCHAs can be stored in a Redis cache as a List. The Redis cache key and the generated batch CAPTCHA List are then returned to the frontend.

[0064] The number of batch verification codes generated randomly each time is not limited. After a batch of verification codes is generated, a batch keyword can be generated for the batch verification codes to facilitate subsequent comparison and indexing. In this embodiment, the batch keyword is represented as Key, and the batch verification codes are obtained by indexing with Key.

[0065] It should be noted that the batch verification codes, the corresponding batch verification codes, and the list of verification codes formed by combining all the verification codes in the batch verification codes will be pre-stored in the cache of the backend server.

[0066] Step S201: Obtain batch verification codes and store them in the front-end cache.

[0067] Because batch verification codes are obtained, each time the front-end device performs verification, if the user cannot see the verification code clearly or wants to change it, the next verification code can be directly retrieved from the front-end cache of that front-end device without having to request the verification code again.

[0068] Step S202: Extract the target verification code from the batch verification codes cached on the front end, and display the target verification code on the front end screen interface. The target verification code has an index value, which represents the extraction relationship of the target verification code from the batch verification codes.

[0069] Optionally, the step of extracting the target verification code from the batch verification codes cached on the front end includes: obtaining a list of verification codes associated with the batch verification codes and generating an index order corresponding to the verification code list; obtaining a verification code from the batch verification codes cached on the front end according to the index order, and using the obtained verification code as the target verification code.

[0070] In this embodiment, after obtaining the batch verification codes, the front-end device stores them in the front-end cache, and retrieves a verification code from the batch verification codes in the front-end cache according to the index order, and displays it on the front-end in a certain form.

[0071] Alternatively, after displaying the target verification code on the front-end screen interface, the method further includes: receiving and responding to the change operation, retrieving the next verification code following the target verification code from the batch verification codes according to the index order, and displaying the next verification code on the front-end screen interface.

[0072] In this embodiment, after receiving the replacement operation, the method further includes: querying whether all the verification codes in the batch verification codes have been used up; if all the verification codes in the batch verification codes have been used up, obtaining new batch verification codes; if not all the verification codes in the batch verification codes have been used up, responding to the replacement operation.

[0073] When a verification code cannot be clearly identified or the user needs to change the verification code, the next verification code is first retrieved from the batch verification codes cached on the front end in index order. If the code is retrieved, the verification code is checked again. If the code is not retrieved, it means that the batch of verification codes has been used up, and a new batch of verification codes is retrieved again.

[0074] Step S203: Receive user input information and send the batch keywords, the index value of the target verification code, and the user input information to the backend server. The user input information refers to the information generated by the user performing the verification operation on the front-end screen interface. The backend server queries the pre-cached target verification code based on the batch keywords and the index value, and compares the verification information in the user input information with the target verification code to obtain the verification result.

[0075] After the user enters the verification code and other relevant information, a verification code verification request is initiated. The front-end device receives the user's input information and sends the cached batch keyword key, the index value of the displayed verification code, and the user's input information (including the user's input verification code) to the back-end server.

[0076] After receiving the verification code request, the backend server uses the batch verification code key sent by the frontend device to retrieve the previously generated batch verification codes from the cached Redis. Then, it extracts the corresponding verification code from the retrieved batch verification codes by displaying the index value of the verification code, and compares it with the verification code filled in by the user in the user input information sent by the frontend device. If they match, the verification is successful; otherwise, the verification fails.

[0077] Step S204: Receive the verification result returned by the backend server.

[0078] Optionally, after receiving the verification result returned by the backend server, the method further includes: if the verification code indicated by the verification information in the user input information in the verification result is consistent with the target verification code, confirming that the verification is successful and displaying a verification success notification on the front-end screen interface; if the verification code indicated by the verification information in the user input information in the verification result is inconsistent with the target verification code, confirming that the verification is unsuccessful and displaying a re-verification notification on the front-end screen interface.

[0079] Through the above embodiments, batch verification codes can be generated at once and retrieved from the front-end cache in the front-end and back-end caches in an indexed order for display. The verification codes can then be located on the back-end for verification using the index. This eliminates the need to call the back-end interface to retrieve the verification codes every time, reducing access frequency and lowering the access pressure on the back-end server from the front-end devices.

[0080] The invention will now be described using another alternative embodiment.

[0081] Example 2

[0082] This invention illustrates the implementation using a backend server as the executing entity.

[0083] This invention also provides a batch verification method for CAPTCHAs, applied to a backend server, which is connected to the frontend device used by the user.

[0084] Figure 3 This is a flowchart of another optional batch verification method according to an embodiment of the present invention, such as... Figure 3 As shown, it includes:

[0085] Step S301: Receive batch keywords, verification code index value and user input information from the front-end device. The user input information refers to the information generated by the user performing a verification operation on the target verification code displayed on the front-end screen interface of the front-end device.

[0086] Step S302: Based on the batch verification codes pre-stored in the batch keyword index key-value pair cache, query the target verification code in the batch verification codes based on the verification code index value, wherein the batch verification codes are pre-cached in the key-value pair cache of the backend server;

[0087] Step S303: Compare the verification information entered by the user with the target verification code to obtain the verification result;

[0088] Step S304: Send the verification result to the front-end device.

[0089] Through the above steps, when verifying the CAPTCHA, the backend server receives the batch keywords, CAPTCHA index value, and user input information from the frontend device. The user input information refers to the information generated by the user performing a verification operation on the target CAPTCHA displayed on the frontend screen interface of the frontend device. Based on the batch CAPTCHAs pre-stored in the batch keyword index key-value pair cache, the server queries the target CAPTCHA in the batch CAPTCHAs based on the CAPTCHA index value. The backend server pre-caches the batch CAPTCHAs in its key-value pair cache. The server compares the verification information of the user input information with the target CAPTCHA to obtain the verification result, and then sends the verification result to the frontend device.

[0090] In this embodiment, by generating verification codes in batches and returning them to the front-end device, the front-end device first iterates through the batch of verification codes when it needs to retrieve them again. Only after it has finished iterating through them does it initiate the back-end service to regenerate the verification codes in batches, thereby reducing the frequency of access to the back-end interface. This solves the technical problem in related technologies where the back-end service needs to be called to regenerate the verification codes every time they need to retrieve them again, resulting in frequent access to the back-end interface.

[0091] The embodiments of the present invention will now be described in detail with reference to the steps described above.

[0092] It should be noted that this embodiment illustrates the execution entity as a backend server that interfaces with the user's frontend device. The backend server interfaces with at least one frontend device, and the types of frontend devices include, but are not limited to: mobile terminals (e.g., mobile phones, tablets, iPads, LED displays), PCs, desktop computers, financial terminals with operating screens, etc. The frontend device is connected to the backend server. In specific applications, this frontend device can also be used in other devices with touchscreens, such as vehicle displays and ATMs.

[0093] Optionally, before receiving the batch keywords, verification code index value, and user input information from the front-end device, the method further includes: receiving a verification code retrieval request sent by the front-end device; responding to the verification code retrieval request, randomly generating N image verification codes, and combining the N image verification codes into a batch verification code, where N is an integer greater than or equal to 2; storing the batch verification code in a key-value pair cache, and generating a batch keyword and verification code list corresponding to the batch verification code; and sending the batch verification code, batch keywords, and verification code list to the front-end device.

[0094] This embodiment improves upon existing CAPTCHA technology by generating CAPTCHAs in batches. Upon receiving a CAPTCHA retrieval request, the backend server randomly generates N image CAPTCHAs (image verification). Alternatively, in the actual generation process, a batch of characters can be randomly generated based on the CAPTCHA retrieval request, and these characters will be used as the batch CAPTCHAs. The generated batch CAPTCHAs are stored in a cache using a specified storage format. For example, the batch CAPTCHAs can be stored in a Redis cache as a List. The Redis cache key and the generated batch CAPTCHA List are then returned to the frontend.

[0095] The number of batch verification codes generated randomly each time is not limited. After a batch of verification codes is generated, a batch keyword can be generated for the batch verification codes to facilitate subsequent comparison and indexing. In this embodiment, the batch keyword is represented as Key, and the batch verification codes are obtained by indexing with Key.

[0096] It should be noted that the batch verification codes, the corresponding batch verification codes, and the list of verification codes formed by combining all the verification codes in the batch verification codes will be pre-stored in the cache of the backend server.

[0097] Step S301: Receive batch keywords, verification code index value, and user input information from the front-end device. The user input information refers to the information generated by the user performing a verification operation on the target verification code displayed on the front-end screen interface of the front-end device.

[0098] The backend server receives a verification code verification request, which carries the batch keywords entered by the frontend device, the verification code index value, and the user input information.

[0099] Step S302: Based on the batch verification codes pre-stored in the batch keyword index key-value pair cache, query the target verification code in the batch verification codes based on the verification code index value. The batch verification codes are pre-cached in the key-value pair cache of the backend server.

[0100] The backend server uses the batch verification code keywords sent by the frontend device to retrieve the previously generated batch verification codes from Redis, and then retrieves the corresponding target verification code from the generated batch verification codes by displaying the index value of the verification code.

[0101] Step S303: Compare the verification information entered by the user with the target verification code to obtain the verification result.

[0102] After the backend server obtains the corresponding target verification code, it compares it with the verification code entered by the user and sent by the frontend device. If they match, the verification passes; otherwise, the verification fails.

[0103] Step S304: Send the verification result to the front-end device.

[0104] Optionally, when the front-end device encounters a verification code that cannot be clearly identified or the user needs to change the verification code, it first retrieves the next verification code from the batch verification codes cached on the front end in index order. If the code is retrieved, the verification code is checked again. If the code is not retrieved, it means that the batch of verification codes has been used up, and a new batch of verification codes is retrieved again.

[0105] Through the above embodiments, batch verification codes can be generated at once and retrieved from the front-end cache in the front-end and back-end caches in an indexed order for display. The verification codes can then be located on the back-end for verification using the index. This eliminates the need to call the back-end interface to retrieve the verification codes every time, reducing access frequency and lowering the access pressure on the back-end server from the front-end devices.

[0106] The invention will now be described in conjunction with another alternative embodiment.

[0107] Figure 4 This is a schematic diagram illustrating an optional method for verifying batch verification codes according to an embodiment of the present invention, such as... Figure 4 As shown, the interaction process between the front-end device and the back-end server includes:

[0108] (1) Generate verification code

[0109] When a front-end device initiates a request to obtain a verification code, the back-end server, upon receiving the request, randomly generates a batch of characters, i.e., batch verification codes, and stores the batch verification codes in a Redis cache using a List type. The back-end server then returns the Redis cached key (corresponding to the batch keywords mentioned above) and the generated batch verification code List (corresponding to the verification code list mentioned above) to the front-end device.

[0110] (2) Verify the verification code

[0111] After receiving the batch verification codes, the front-end device stores them in the front-end cache. Then, it retrieves a verification code from the cached batch verification codes using an index, displays it on the front-end device in a specific format, and initiates a verification code verification request after the user enters the code. The front-end device sends the Redis cache key for the batch verification codes, the index value of the displayed verification code, and the user-entered verification code to the back-end server. Upon receiving the request, the back-end server uses the Redis key sent by the front-end device to retrieve the previously generated batch verification codes from Redis. Then, it uses the index value of the displayed verification code to retrieve the corresponding target verification code from the generated batch verification codes and compares it with the user-entered verification code sent by the front-end device. If they match, the verification passes; otherwise, it fails.

[0112] (3) Re-obtain the verification code

[0113] When a verification code cannot be clearly identified or the user needs to change the verification code, the next verification code is first obtained from the batch verification codes cached on the front end in index order. If it is obtained, step (2) is repeated to verify the verification code. If it is not obtained, it means that the batch verification codes have been used up, and step (1) is repeated to obtain a new batch of verification codes.

[0114] The above implementation method can generate multiple verification codes at once, store them in the front-end and back-end server caches using a List type, retrieve and display them from the front-end device cache using an index, and then locate the verification code on the back-end server for verification using the index. This eliminates the need to call the back-end server interface to retrieve the verification code every time, reducing access frequency and reducing access pressure.

[0115] The invention will now be described using another alternative embodiment.

[0116] Example 3

[0117] The batch verification device for verification codes provided in this embodiment includes multiple implementation units, each of which corresponds to a specific implementation step in Embodiment 1 above.

[0118] This invention provides a batch verification device for CAPTCHAs, which is applied to a front-end device used by a user and connected to a back-end server.

[0119] Figure 5 This is a schematic diagram of an optional batch verification device according to an embodiment of the present invention, such as... Figure 5 As shown, the verification device may include: a first acquisition unit 50, an extraction unit 51, a first transmission unit 52, and a first receiving unit 53, wherein...

[0120] The first acquisition unit 50 is used to acquire batch verification codes and store the batch verification codes in the front-end cache. The batch verification codes contain N verification codes to be used and the batch verification codes correspond to batch keywords. The front-end device includes: front-end cache and front-end screen interface, where N is an integer greater than or equal to 2.

[0121] Extraction unit 51 is used to extract the target verification code from the batch verification codes cached at the front end and display the target verification code on the front end screen interface. The target verification code has an index value, which represents the extraction relationship between the batch verification codes and the target verification code.

[0122] The first sending unit 52 is used to receive user input information and send the batch keywords, the index value of the target verification code, and the user input information to the backend server. The user input information refers to the information generated by the user performing a verification operation on the front-end screen interface. The backend server queries the pre-cached target verification code based on the batch keywords and the index value, and compares the verification information in the user input information with the target verification code to obtain the verification result.

[0123] The first receiving unit 53 is used to receive the verification result returned by the backend server.

[0124] The aforementioned batch verification code verification device can acquire batch verification codes through the first acquisition unit 50 and store them in the front-end cache during the verification process. The extraction unit 51 extracts the target verification code from the batch verification codes in the front-end cache and displays it on the front-end screen interface. Then, the first sending unit 52 receives user input information and sends the batch keywords, the index value of the target verification code, and the user input information to the back-end server. The user input information refers to the information generated by the user performing a verification operation on the front-end screen interface. The back-end server queries the pre-cached target verification code based on the batch keywords and index value, compares the verification information in the user input information with the target verification code, and obtains the verification result. The first receiving unit 53 receives the verification result returned by the back-end server. In this embodiment, by batch generating verification codes and returning them to the front-end device, when the front-end device re-acquires verification codes, it first traverses the batch verification codes. Only after traversing all the codes does it initiate the back-end service to re-batch generate verification codes, reducing the frequency of back-end interface access. This solves the technical problem in related technologies where the back-end service needs to be called to regenerate verification codes every time a verification code is re-acquired, resulting in frequent access to the back-end interface.

[0125] Optionally, the batch verification device further includes: a first sending module, used to send a verification code acquisition request to a backend server before acquiring the batch verification code, wherein, after receiving the verification code acquisition request, the backend server randomly generates N image verification codes, combines the N image verification codes into a batch verification code, stores the batch verification code in a key-value pair cache, and generates a batch keyword and a verification code list corresponding to the batch verification code; and a first receiving module, used to receive the batch verification code, the batch keyword corresponding to the batch verification code, and the verification code list returned by the backend server.

[0126] Optionally, the extraction unit includes: a first acquisition module, used to acquire a list of verification codes associated with the batch verification codes and generate an index order corresponding to the list of verification codes; and a second acquisition module, used to acquire a verification code from the batch verification codes cached at the front end according to the index order and use the acquired verification code as the target verification code.

[0127] Optionally, the batch verification device further includes: a second receiving module, used to receive a change operation after the target verification code is displayed on the front-end screen interface, and respond to the change operation by retrieving the next verification code after the target verification code from the batch verification codes according to the index order, and displaying the next verification code on the front-end screen interface.

[0128] Optionally, the batch verification device further includes: a first query module, used to query whether all the verification codes in the batch verification code have been used up after receiving the replacement operation; a third acquisition module, used to acquire new batch verification codes if all the verification codes in the batch verification code have been used up; and a first response module, used to respond to the replacement operation if not all the verification codes in the batch verification code have been used up.

[0129] Optionally, the batch verification device further includes: a display module, used to, after receiving the verification result returned by the backend server, if the verification code indicated by the verification information in the verification information indicated by the verification result in the user input information matches the target verification code, confirm that the verification is successful and display a verification success notification on the front-end screen interface; and a confirmation module, used to, if the verification code indicated by the verification information in the verification information indicated by the verification result in the user input information does not match the target verification code, confirm that the verification is unsuccessful and display a re-verification notification on the front-end screen interface.

[0130] The invention will now be described in conjunction with another alternative embodiment.

[0131] This invention provides another batch verification device for CAPTCHAs, which is applied to a backend server and connected to the frontend device used by the user.

[0132] Figure 6This is a schematic diagram of another optional batch verification device according to an embodiment of the present invention, such as... Figure 6 As shown, the batch verification code verification device includes: a second receiving unit 60, a query unit 61, a comparison unit 62, and a second sending unit 63, wherein,

[0133] The second receiving unit 60 is used to receive the batch keywords, verification code index value and user input information input by the front-end device. The user input information refers to the information generated by the user performing a verification operation on the target verification code displayed on the front-end screen interface of the front-end device.

[0134] The query unit 61 is used to query the target verification code in the batch verification code based on the verification code index value based on the batch verification code pre-stored in the batch keyword index key-value pair cache. The batch verification codes are pre-cached in the key-value pair cache of the backend server.

[0135] The comparison unit 62 is used to compare the verification information of the user input information with the target verification code to obtain the verification result;

[0136] The second sending unit 63 is used to send the verification result to the front-end device.

[0137] In the aforementioned batch verification code verification device, when the backend server verifies the verification code, it receives the batch keywords, verification code index value, and user input information from the frontend device through the second receiving unit 60. The user input information refers to the information generated by the user performing a verification operation on the target verification code displayed on the frontend screen interface of the frontend device. The query unit 61 queries the target verification code in the batch verification code based on the batch verification code index value and the batch verification code cached in advance. The batch verification codes are pre-cached in the key-value pair cache of the backend server. The comparison unit 62 compares the verification information of the user input information with the target verification code to obtain the verification result. The verification result is then sent to the frontend device through the second sending unit 63.

[0138] In this embodiment, by generating verification codes in batches and returning them to the front-end device, the front-end device first iterates through the batch of verification codes when it needs to retrieve them again. Only after it has finished iterating through them does it initiate the back-end service to regenerate the verification codes in batches, thereby reducing the frequency of access to the back-end interface. This solves the technical problem in related technologies where the back-end service needs to be called to regenerate the verification codes every time they need to retrieve them again, resulting in frequent access to the back-end interface.

[0139] Optionally, the batch verification device further includes: a third receiving module, used to receive a verification code retrieval request sent by the front-end device before receiving the batch keywords, verification code index value, and user input information input by the front-end device; a second response module, used to respond to the verification code retrieval request, randomly generate N graphic verification codes, and combine the N graphic verification codes into a batch verification code, where N is an integer greater than or equal to 2; a storage module, used to store the batch verification codes in a key-value pair cache, and generate a batch keyword and a verification code list corresponding to the batch verification codes; and a second sending module, used to send the batch verification codes, batch keywords, and verification code list to the front-end device.

[0140] The aforementioned batch verification code verification device may also include a processor and a memory. The first acquisition unit 50, extraction unit 51, first sending unit 52, first receiving unit 53, second receiving unit 60, query unit 61, comparison unit 62, and second sending unit 63 are all stored in the memory as program units, and the processor executes the aforementioned program units stored in the memory to realize the corresponding functions.
