A bypass forwarding-based mail management method and system

Abstract

The application discloses a bypass forwarding-based mail management method and system. The method is applied to a mail management system, and the mail management system comprises a server, a management terminal and a mail retrieval system. The mail retrieval system receives a retrieval request sent by the management terminal. The mail retrieval system performs word segmentation processing on retrieval content of the retrieval request to obtain a target word segmentation result. The mail retrieval system queries a target mail ID corresponding to a target word segmentation index matched with the target word segmentation result, so as to call a target mail corresponding to the target mail ID by a mail management background. In this way, the mail retrieval system performs retrieval on at least one word segmentation index according to the target word segmentation result, and obtains a target word segmentation index matched with the target word segmentation result. Since the at least one word segmentation index comprises a pinyin index, a partial character index and a component index, compared with complete matching or fuzzy matching in the prior art, the method can adapt to complex retrieval requirements, improve a hit rate of retrieval and improve mail management efficiency.

[0052] The multiple referred to in the embodiments of the present application refers to greater than or equal to two. It should be noted that in the description of the embodiments of the present application, the words "first", "second", etc. are only used for the purpose of distinguishing the description and cannot be understood as indicating or implying relative importance, nor can it be understood as indicating or implying order.

[0053] In order to make the above objectives, characteristics and advantages of the present application more apparent, easy to understand, the embodiments of the present application are further described in detail below in combination with the drawings and specific embodiments. It can be understood that the specific embodiments described herein are only used to explain the present application, and not to limit the present application. In addition, it should be noted that, for the convenience of description, only the parts related to the present application are shown in the drawings, not all structures.

[0054] First, the part of the proper nouns involved in the embodiments of the present application is explained:

[0055] 1) Client / Server (C / S) architecture, the server is responsible for data management, and the client completes the interaction with the user.

[0056] 2) Exact match, which means that the searched field and the search rule field are exactly the same.

[0057] 3) Fuzzy match, which means that the searched field contains the search rule field and may also contain other content. For example, the rule "mail body" can be successfully fuzzy matched with "* mail body *", where "*" means wildcard and can represent any value.

[0058] 4) Lexical segmentation, simply called word segmentation, which divides a certain text into several words, such as "mail body", one of the word segmentation results is: "mail", "body", "text", "four words", which can also be divided into "mail" and "text" two words. The division result depends on the specific rule.

[0059] The normal operation of an enterprise cannot be separated from communication with the outside world, therefore, even the internal mail management system of an enterprise will face the challenge of an insecure Internet environment in the process of use, such as risk mail containing phishing content, identifying and timely disposing of such risk mail is beneficial to avoid unnecessary losses.

[0060] When an enterprise solves the problem of risk mail prevention, it generally considers building a gateway system, which identifies and filters risk mail using the gateway system when the risk mail arrives at the Internet entrance of the enterprise network, and timely prevents such mail from entering the internal agency. However, the gateway system cannot guarantee 100% correct identification and interception of risk mail, and it is inevitable that some fish will slip through the net.

[0061] Consider the following scenario: if the risk mail is not intercepted correctly by the gateway system, it has entered the enterprise internal mail management system. The user reviews the mail and identifies the risk content, and reports to the administrator. The administrator plans to conduct a comprehensive investigation within the enterprise to determine whether there are similar risk emails to avoid other users receiving similar risk emails from suffering losses. How to locate the risky email in a large number of emails has become an inevitable problem in the construction of enterprise information security.

[0062] See Figure 1 , a prior art mail management system structure schematic diagram provided for the embodiments of the present application. In the process of querying the data in the mail database by the administrator management end through the mail management background, the mail system generally saves the sender mail address, mail subject, and even part of the mail body and other key information of the mail in the database when receiving the Internet mail. The database system provides complete matching or fuzzy matching search capability, and the administrator can query all the above data within a specified time through the database, and check one by one whether other mails have the same or similar above-mentioned content as the risk mail. If the matching is successful, it means that the risk mail is retrieved. In the process of obtaining the mail of the logged-in user from the mail background by the user client, after obtaining the user mail, the text data in the mail is processed by word segmentation, and an index is established according to the word segmentation result, so as to provide better search capability than complete matching or fuzzy matching.

[0063] Applicants have found that the prior art mail management system has the following problems:

[0064] First, the search function of the existing mail management system is searched by complete matching or fuzzy matching, and the rules of complete matching or fuzzy matching are relatively strict, such as the rule "mail body" can be successfully fuzzy matched with "mail body", but cannot be successfully matched with "mail body", which makes the mail management efficiency low.

[0065] Second, the existing mail management system usually only stores the sender address, mail subject and other data in the original text. In order to reduce the running cost of the mail management system and improve the security of the mail management system, the mail body is generally compressed and encrypted when storing the mail, that is, the mail body which occupies the most storage space and is the most sensitive needs to be compressed and encrypted before storage. However, compression and encryption processing will change the format of the data, and the data after compression and encryption processing is completely inconsistent with the original text, so the key information matching based on the database cannot realize the search of the data in the mail body.

[0066] Third, risk mail in order to avoid the gateway system interception and other security defense means, will also be confused to the data of risk mail processing. For example: a risk mail contains the title of "subsidy" phishing link, may use homophonic, radical or similar radicals, will link title to "post" and other changes, in order to avoid the interception of gateway system, but still can play a certain role in attracting users. In this example, the rule "subsidy" also can't match "post" successfully, can't succeed. Therefore, the function of full match or fuzzy match provided by the database can't meet the more complex retrieval requirements.

[0067] Fourth, based on the user data of the word segmentation retrieval function is the user client in the acquisition of the user has logged in the mail data, in the user equipment on the word segmentation index, the word segmentation index only contains the current user data, only can retrieve the current user mail, can't retrieve other user mail.

[0068] Based on this, the embodiment of the application provides a kind of based on bypass forwarding mail management method and system, it is applied to mail management system, mail management system includes server, management end and mail retrieval system, server includes mail background and mail management background, in the method, mail retrieval system receives the retrieval request sent by management end;Mail retrieval system carries out word segmentation processing to the retrieval content of retrieval request, obtains target word segmentation result;Target word segmentation result includes the original text of Chinese text after retrieval content word segmentation processing, pinyin, partial and head;At least one word segmentation index corresponding to the mail of mail retrieval system storage by mail background bypass forwarding is stored, and the value of at least one word segmentation index is mail identifier ID;At least one word segmentation index includes original text index, pinyin index, partial index and head index;Mail retrieval system queries target mail ID corresponding to target word segmentation index matched with target word segmentation result, so that management end calls mail management background and processes target mail ID corresponding target mail.

[0069] Thus, the mail retrieval system performs word segmentation processing on the retrieval content of the retrieval request, retrieves in at least one word segmentation index according to the target word segmentation result, and obtains a target word segmentation index matched with the target word segmentation result. Since the at least one word segmentation index includes a pinyin index, a partial character index, and a component head index, compared with the full match or fuzzy match in the prior art, the complex retrieval requirement can be adapted, the hit rate of retrieval is improved, and the bypass retrieval method can be avoided to some extent, thereby improving the mail management efficiency. In addition, in the mail retrieval system in the embodiment of the present application, at least one word segmentation index corresponding to the mail content in the bypass forwarded mail is included, the retrieval function of non-original text storage data is covered, the hit rate of retrieval is improved, the target mail is quickly and accurately retrieved, and the mail management efficiency is improved. Moreover, the mail retrieval system in the embodiment of the present application can provide a retrieval function covering all mail data of users, and the management end can retrieve the mail of all other users through the mail retrieval system. Compared with the prior art, in the embodiment of the present application, the index content is generally the ID of a mail, and the presence of a mail ID in the index of a certain word indicates that the content of the mail contains the word. The user can retrieve whether the risk content exists in the mail of the user according to the key word in the risk mail.

[0146] In the embodiment of the application, the mail retrieval system performs word segmentation on the text content (not including image, audio and video and other non-text format content) in the initial mail, and if the Chinese text is involved, when the word segmentation index of the original text of the Chinese text is established, multiple word segmentation indexes of the pinyin, partial character and radical of the Chinese text are also established, and the keys of each word segmentation index are respectively the original text, pinyin, partial character and radical, and the value of the index is the ID of the initial mail.

[0147] As an example, the email retrieval system receives the initial email A forwarded by the email background bypass, and the email ID of the initial email A is 111. The text content in the initial email A (for example, the text content "補帖") is obtained. First, the text content is segmented to obtain multiple initial segmentation results ["補"] and ["帖"]. For each initial segmentation result, at least one segmentation index is established. Then, establishing at least one segmentation index includes the original text index {補, 111} {帖, 111}, the pinyin index {bǔ, 111} {tiē, 111}, the radical index {衤, 111} {刂, 111}, and the radical index {衤, 111} {刂, 111}. Another example is that the email retrieval system receives the initial email B forwarded by the email background bypass, and the email ID of the initial email B is 222. The text content in the initial email B (for example, the text content "补贴") is obtained. First, the text content is segmented to obtain multiple initial segmentation results ["补"] and ["贴"]. For each initial segmentation result, at least one segmentation index is established. Then, establishing at least one segmentation index includes {补, 222} {贴, 222} {bǔ, 222} {tiē, 222}, the radical index {衤, 百, 222} {贝, 222}, and the radical index {衤, 222} {贝, 222}.

[0148] Based on the above embodiments, the email retrieval system stores the obtained segmentation indexes for retrieving the retrieval requests sent by the management terminal. S27 provided by the embodiments of the present application may include: The email retrieval system stores the original text index, the pinyin index, the radical index, and the radical index.

[0149] It should be noted that the premise for the embodiments of the present application to execute is that the email background supports the bypass forwarding function, which can forward the original email to other systems. Each email has a unique email ID. The email management background supports querying email data from the email database according to the email ID and can perform further operations (such as viewing the original email, querying the recipients of the email, or deleting the email, etc.).

[0150] First, the embodiments of the present application use a retrieval method based on segmentation indexes to retrieve email content, and establish segmentation indexes for the pinyin, radicals, and radicals of Chinese texts when constructing segmentation indexes, which is beneficial to improving the retrieval hit rate, avoiding bypassing retrieval, improving email management efficiency, and improving the security of the email management system to a certain extent.

[0151] Moreover, the email retrieval system of the embodiments of the present application is established on the basis of all users and supports retrieving data within the scope of all users, including email content such as the email body. The retrieval scope is wider, which is beneficial to improving the retrieval hit rate and improving the management efficiency of the email management system to a certain extent.

[0152] Then, the SMTP-based mail bypass forwarding function is a common function of the mail management system, and most of the mail management systems have supported. According to the unique mail ID retrieval data, the basic function of the system, most of the mail management systems support the query of the specified mail according to the mail ID. The embodiment of the application reuses the original mail management system, adds a mail retrieval system on the basis of the original mail management system, and uses the existing function of the original mail management system to achieve the purpose of retrieval and processing, without the need for large-scale modification of the original associated mail system, thereby reducing the modification cost.

[0153] In a possible implementation, the mail management system further includes a gateway system, and before S21, the method provided by the embodiment of the application can further include:

[0154] S20, the gateway system checks the initial mail and obtains a checking result; when the checking result represents that the initial mail is not a junk mail, the gateway system sends the initial mail to the mail background.

[0155] In the embodiment of the application, the mail first arrives at the gateway system in the mail management system, and then arrives at the mail background after being checked by the gateway system.

[0156] In a possible implementation, the service end further includes a mail database, and the method provided by the embodiment of the application can further include:

[0157] S31, the mail management background receives the first query request sent by the management end;

[0158] S32, the mail management background retrieves the first mail corresponding to the first query request in the mail database;

[0159] S33, the mail management background sends the first mail to the management end.

[0160] In the embodiment of the application, the administrator can send a query request to the mail management background through the management end, and match the mail data of all users stored in the mail database in the mail database.

[0161] In a possible implementation, the mail management system further includes a client, and the service end further includes a mail database, and the method provided by the embodiment of the application further includes:

[0162] S41, the mail background receives the second query request sent by the client;

[0163] S42, the mail background retrieves the second mail corresponding to the second query request in the mail database;

[0164] S43, the mail background sends the second mail to the client.

[0165] In the embodiments of the present application, a user initiates a query request such as a mail viewing request to a mail background through a client, the mail background retrieves and returns mail data of the user from a mail database, and the mail data is displayed to the user through the client.

[0166] In the embodiments of the present application, the mail background supports a bypass forwarding function, can forward mails to a mail retrieval system, each mail has a unique ID, the mail management background supports querying mail data according to the mail ID to the mail database, and can further operate (such as viewing the original text of the mail, querying the recipients of the mail, or deleting the mail).

[0167] In this way, the embodiments of the present application improve the commonly used architecture of the mail management system, add a mail retrieval system, obtain the original data of the mail through the bypass forwarding mode, and establish a full-system and full-user-level word segmentation index to provide a retrieval function that can cover all users and can cover non-original storage data.
