FIG. 3 is a flow chart illustrating a method of cheating behavior detection according to another exemplary embodiment, which may be applied in the implementation environment shown in FIG. 1 and described above, and which may include the following implementation steps:
Step 301: when the reference operation of the online answering application is detected, address information of a proxy server is acquired, and the proxy server is used for monitoring network search requests in the running process of the online answering application, wherein the network search requests comprise search contents.
In the running process of the online answer application, when the electronic device sends a network search request, the online search may be performed on the current question, and at this time, cheating may exist, so that the network search request needs to be monitored. As an example, whether the electronic device sent a web search request may be monitored by a proxy server, so the proxy server may be set up before answering the question. Further, before answering, when a reference operation to the online answering application is detected, address information of the proxy server may be acquired, so that the proxy server is set according to the address information.
As an example, the reference operation may include an application launch operation or a start answer operation. According to the reference operation, detecting the reference operation applied to the online answer may include two possible implementations as follows:
the first implementation mode: and when the application starting operation of the online answering application is detected, determining that the reference operation of the online answering application is detected.
That is, when the user opens the online answering application, whether the user starts answering or not, the terminal determines that the reference operation to the online answering application is detected after detecting the operation, and at this time, the address information of the proxy server is obtained.
As an example, the electronic device may also provide the user with an option of whether to agree to set the proxy server, and when the user selects the agreement, the electronic device acquires address information of the proxy server; otherwise, if the user selects disagreement, the electronic device may close the online answer application, and the user cannot perform any operation on the online answer application, or the electronic device may prohibit starting to answer, that is, the user can only browse on the online answer application, but cannot start to answer.
The second implementation mode: and when the starting answer operation of the online answer application is detected, determining that the reference operation of the online answer application is detected.
That is, when the user opens the online answering application, if the user does not answer the questions, the online answering application is closed after the user browses the information, the electronic device may not acquire the address information of the proxy server, and at this time, the electronic device may directly perform communication connection with the background server; if the user selects to start answering after opening the online answering application or selects to start answering after browsing other information, the terminal determines that the reference operation to the online answering application is detected after detecting the operation, and at the moment, the address information of the proxy server is acquired.
The method includes the steps that when a user opens an online answer application, if the user browses only ranking, answer questions, winning prizes and other information of the user, the online answer application is closed after browsing is finished, answer operation is not performed, namely the electronic equipment does not detect reference operation of the user on the online answer application, and in the process of using the online answer application by the user, the electronic equipment can directly perform communication connection with a background server without obtaining address information of the proxy server; if the user opens the online answer application, the user selects to answer, or browses the ranking, answer questions, winning prizes and other information, the electronic equipment determines that the reference operation of the online answer application is detected.
Further, the electronic device determines whether to agree to set the proxy server or not when the reference operation of the online answer application is detected, and when the user selects the agreement, the electronic device acquires address information of the proxy server; otherwise, if the user selects disagreement, the electronic device may close the online answer application, and the user cannot perform any operation on the online answer application, or the electronic device may prohibit starting to answer, that is, the user can only browse on the online answer application, but cannot start to answer.
As one example, obtaining address information for a proxy server includes the operations of: when the user agrees to the electronic device to set up the proxy server, the address information of the proxy server, which includes an IP (Internet Protocol, protocol of interconnection between networks) address and a port number, may be transmitted to the electronic device by the backend server, and the address information is used for the electronic device to establish a connection with the proxy server, by itself, by the backend server.
Step 302: a communication connection is established with the proxy server based on the address information.
After the electronic equipment acquires the address information sent by the background server, communication connection is established with the proxy server based on the IP address and the port number.
After the proxy server is used, the electronic device can monitor the network search request through the proxy server when sending the network search request to the background server. That is, as long as the online answering application is running and the electronic device completes the communication connection with the proxy server, any network search request sent by the electronic device can be monitored by the proxy server, but when the user closes the online answering application, the communication connection between the electronic device and the proxy server is disconnected, and the proxy server does not monitor the network search request any more.
The user agrees that the electronic device sets the proxy server to connect with the network, and answers questions, if the user enters other application interfaces in the answer process, but the online answer application is still running in the background at this time, the user sends a network search request on the other application interfaces, and the proxy server can monitor the network search request.
Step 303: and acquiring search content, namely acquiring the question content of the current question, wherein the current question is the question currently displayed by the online answering application, and the search content is the search content detected during the running of the online answering application.
As described above, in some embodiments, when the user sends a web search request during the running of the online answer application, the web search request may be monitored by a proxy server, where the web search request includes search content, and the proxy server may obtain the search content in the web search request to the electronic device. In implementations, the proxy server obtaining the search content to the electronic device may include two possible implementations:
the first implementation mode: search content fed back by the proxy server is received.
As an example, when the electronic device sends a network search request, the proxy server acquires the search content after monitoring the network search request, and then the search content can be sent to the background server, and the background server feeds back the search content to the electronic device.
The second implementation mode: and receiving a network search request fed back by the proxy server, and acquiring search content from the network search request.
As an example, when the electronic device sends a network search request, the proxy server sends the network search request to the background server after monitoring the network search request, and the background server feeds back the network search request to the electronic device. And after the electronic equipment receives the network search request, acquiring the search content from the network search request.
In addition, the electronic device obtains the topic content of the current topic. As an example, prior to obtaining the topic content of the current topic, the topic content of the current topic may be cached in a cache file, in which case the topic content of the current topic is obtained from the cache file.
That is, in the process of answering the user, each question displayed by the online answering application, the electronic device may cache the content of the current question into a cache file, where the content of the current question may include text information, and the cache file may be stored locally in the electronic device.
As an example, after the electronic device caches the content of the question in the cache file, when the answering time of the question is over, the electronic device displays the next question by using the online answering application, and can continuously cache the content of the next question in the cache file and cover the content of the previous question, so that the storage space can be saved.
Referring to fig. 4, the online answering application shows a first question, the electronic device caches the content of the first question in the cache file, at this time, only the content of the first question in the cache file, and after 30 seconds, the online answering application shows a second question, and the electronic device caches the content of the second question, because the content of the first question already exists in the cache file, the content of the first question is covered by the content of the second question, and the content of the second question is also cached in the cache file, so that the storage space is saved.
It should be noted that, in the above example, the content of each topic is cached in the same cache file, and the content of the previous topic is covered by the content of the current topic, so as to save storage space, and in other embodiments, the content of each topic may also be cached in different cache files respectively. In the above example, the content of each question is cached in the cache file, but in other embodiments, the content of each question may be directly obtained from the online answer application without caching the content of each question, which is not limited in the embodiments of the present application.
Furthermore, the electronic device can display information such as a user account number of the user, the sequence of the currently displayed questions, the remaining answering time of the current questions, the questions and options of the current questions and the like in an answering interface of the online answering application.
It should be noted that the implementation manner of obtaining the search content is merely exemplary, and in another embodiment, the electronic device may also directly monitor the network search request and actively obtain the search content, which is not limited in this embodiment of the present application.
Step 304: a degree of matching between the search content and the topic content is determined.
The electronic device may send a plurality of network search requests during the running of the online answer application, and the network search requests may be, for example, network search requests sent by the cheating software for searching the question content, where the search content of the network search requests includes keywords in the question content or text information in the question content, and the like; it may also be a web search request sent by another application installed on the electronic device, where the search content of the web search request may include text information and the like. To determine whether a network search request monitored during the operation of the online answer application was sent by the cheating software, the electronic device may determine a degree of matching between the search content and the topic content.
As one example, determining the degree of matching between search content and topic content may include two possible implementations:
the first implementation mode: and when the search keyword is included in the topic content, determining that the matching degree between the search content and the topic content reaches a reference similarity threshold.
That is, when the search content includes a search keyword, whether the search keyword is included in the topic content is detected, and if the search keyword is included in the topic content, it is explained that the search content is related to the current topic, so that it can be determined that the matching degree between the search content and the topic content reaches the reference similarity threshold; if the search keyword is not included in the topic content, the search content is not related to the current topic, so that the matching degree between the search content and the topic content can be determined to not reach the reference similarity threshold.
The reference similarity threshold may be set by a user according to an actual requirement, or may also be set by default by the electronic device, which is not limited in the embodiment of the present application.
The second implementation mode: when the search content comprises text information, text matching is carried out on the search content and the topic content, and whether the matching degree between the search content and the topic content reaches a reference similarity threshold value is determined.
As an example, when the search content includes text information, the search content and the topic content may be matched to determine a similarity of the search content and the topic content, thereby determining whether the matching degree between the search content and the topic content reaches a reference similarity threshold according to the similarity.
It should be noted that the above two implementations are merely exemplary, and in another embodiment, the matching degree between the search content and the topic content may be determined in other manners, for example, if the search content is non-text information such as a code, it may be directly determined that the matching degree between the search content and the topic content reaches the reference similarity threshold, which is not limited in the embodiments of the present application.
Step 305: and determining that the cheating behavior is detected when the matching degree between the search content and the topic content reaches a reference similarity threshold.
When the matching degree between the search content and the topic content reaches the reference similarity threshold value, the user is indicated to perform online search on the current topic possibly by using the cheating software, so that the cheating behavior can be determined to be detected. Otherwise, when the matching degree between the search content and the question content does not reach the reference similarity threshold, the user is not used for carrying out online search on the current question by using the cheating software, so that the fact that no cheating behavior is detected can be determined.
As an example, after determining that the cheating behavior is detected, the following two operations may be further included:
the first operation: and sending a cheating notification message to a background server, wherein the cheating notification message carries a user account and cheating times, the cheating notification message is used for indicating the background server to determine whether the user account is effective in answering according to the cheating times, the user account is an account logged in to an online answering application, and the background server is used for providing the question content.
Further, when the background server records that the cheating frequency of the user account reaches the threshold value of the reference cheating frequency, the background server can record that the answer of the user account is invalid and can inform the electronic equipment to close the answer interface.
The reference cheating frequency threshold may be set by a user according to actual needs, or may be set by default by the electronic device, which is not limited in the embodiment of the present application.
That is, when the electronic device detects the cheating behavior, the user account information of the user and the number of cheating times of the user may be sent to the background server, and the background server records the user account information and counts the number of cheating times of the user account. When the cheating times of the user reach the threshold value of the reference cheating times, the background server can record the answer of the user as invalid and can inform the electronic equipment to close the answer interface. Further, the electronic device may also send a notification message to the user to notify the user that the account is sealed, and subsequently the user cannot log in the online answer application using the user account any more.
It is worth mentioning that the user cheating times are recorded through the background server, so that even if the user changes the electronic equipment to log in the online answer application, the user account cheating times can be accurately counted, and the accuracy of cheating behavior detection is guaranteed.
