For ordinary technicians in this field, other drawings can also be obtained based on these drawings.

[0052] The multiple involved in the embodiments of the present application means 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 they be understood as indicating or implying an order.

[0053] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the embodiments of the present application are further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It is understood that the specific embodiments described herein are only used to explain the present application and are not intended to limit the present application. In addition, it should be noted that, for ease of description, only the parts related to the present application are shown in the accompanying drawings, not all structures.

[0054] First, some of the terms used in the examples of this application are 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 means that the searched field is exactly the same as the search rule field.

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

[0058] 4) Lexical segmentation, also known as word segmentation, is the process of dividing a text into several words. For example, the word segmentation result of "email body" is four words: "mail", "item", "body", and "text". It can also be divided into two words: "email" and "body". The segmentation result depends on the specific rules.

[0059] The normal operation of an enterprise is inseparable from communication with the outside world. Therefore, even the internal email management system of an enterprise will face the challenge of an unsafe Internet environment during use, such as risky emails containing phishing content. Identifying and promptly handling such risky emails can help avoid unnecessary losses.

[0060] When enterprises are trying to solve the problem of risky email prevention, they usually consider building a gateway system. When risky emails arrive at the Internet entrance of the enterprise network, the gateway system is used to identify and filter risky emails and promptly prevent such emails from entering the organization. However, the gateway system cannot guarantee 100% correct identification and interception of risky emails, and it is inevitable that some of them slip through the net.

[0061] Consider the following scenario: If a risky email is not correctly intercepted by the gateway system and has entered the company's internal email management system, the user will identify the risky content after reading the email and report it to the administrator. The administrator intends to conduct a comprehensive investigation within the company to see if there are similar risky emails to prevent other users who receive similar risky emails from suffering losses. How to locate risky emails among a large number of emails has become an inevitable problem in the company's information security construction.

[0062] See also Figure 1 , is a structural diagram of an email management system in the prior art provided in an embodiment of the present application. In the process of the administrator querying the data in the email database through the email management background, when the email system receives an Internet email, it generally saves the sender's email address, email subject and even part of the email body and other key information in the database. The database system provides a complete match or fuzzy match retrieval capability. The administrator can query the database for all the above data within a specified time, and check one by one whether other emails have the same or similar content as the risk email. If the match is successful, it means that the risk email has been retrieved. In the process of the user client obtaining the email of the logged-in user from the email background, after obtaining the user's email, the text data in the email is segmented, and an index is established based on the segmentation results, so as to provide a retrieval capability that is better than a complete match or fuzzy match.

[0063] The applicant has found that the email management system in the prior art has the following problems:

[0064] First, the search function of the existing email management system is to search through complete matching or fuzzy matching, and the rules of complete matching or fuzzy matching are relatively strict. For example, the rule "the content of the message" can be successfully fuzzily matched with the "body of the email", but cannot be successfully matched with the "body of the email", which makes the email management efficiency low.

[0065] Second, existing email management systems usually only store the sender address, email subject and other data in the original text. In order to reduce the operating costs of the email management system and improve the security of the email management system, the email body is generally compressed and encrypted when storing emails. In other words, the email body, which takes up the most storage space and is the most sensitive, needs to be compressed and encrypted before storage. However, compression and encryption will change the format of the data. The compressed and encrypted data is completely inconsistent with the original text. Therefore, it is impossible to retrieve the data in the email body based on key information matching in the database.

[0066] Third, in order to circumvent security and air defense measures such as gateway system interception, risky emails will also be misleading in their data. For example, a risky email contains a phishing link titled "Subsidy". It may use homophones, radicals, or characters with similar radicals to change the link title to "Bu Tie" to circumvent the interception of the gateway system, but it can still play a certain role in luring users. In this example, the rule "Subsidy" cannot be successfully matched with "Bu Tie". Therefore, the full match or fuzzy match functions provided by the database cannot meet more complex retrieval requirements.

[0067] Fourth, the word segmentation search function based on user data is a word segmentation index on the user device when the user client obtains the email data of the logged-in user. The word segmentation index only contains the data of the current user and can only retrieve the emails of the current user, but not the emails of other users.

[0068] Based on this, an embodiment of the present application provides a mail management method and system based on bypass forwarding, which is applied to a mail management system. The mail management system includes a server, a management end and a mail retrieval system. The server includes a mail backend and a mail management backend. In the method, the mail retrieval system receives a retrieval request sent by the management end; the mail retrieval system performs word segmentation processing on the retrieval content of the retrieval request to obtain a target word segmentation result; the target word segmentation result includes the original text, pinyin, radicals and radicals of the Chinese text after the word segmentation processing of the retrieval content; the mail retrieval system stores at least one word segmentation index corresponding to the mail forwarded by the mail backend bypass, and the value of at least one word segmentation index is a mail identifier ID; at least one word segmentation index includes an original text index, a pinyin index, a radical index and a radical index; the mail retrieval system queries the target mail ID corresponding to the target word segmentation index that matches the target word segmentation result, so that the management end calls the mail management backend to process the target mail corresponding to the target mail ID.

[0069] In this way, the search content of the search request is segmented by the mail retrieval system, and the target segmentation result is retrieved in at least one segmentation index to obtain the target segmentation index that matches the target segmentation result. Because at least one segmentation index includes a pinyin index, a radical index, and a radical index, compared with the complete match or fuzzy match in the prior art, it can adapt to complex retrieval needs, improve the hit rate of retrieval, and to a certain extent avoid the method of bypassing the retrieval, thereby improving the efficiency of mail management; in addition, the mail retrieval system in the embodiment of the present application includes at least one segmentation index corresponding to the mail content in the bypass forwarded mail, covering the retrieval function including non-original storage data, improving the hit rate of retrieval, quickly and accurately retrieving the target mail, thereby improving the efficiency of mail management. In addition, the mail retrieval system in the embodiment of the present application can provide a retrieval function covering the mail data of all users, and the management end can retrieve the mails 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 an email, and the presence of an email ID in the index of a certain word segmentation means that the content of the email contains the word. Users can search whether there is risky content in the user's email based on the key words in the risky email.

[0070] To facilitate understanding of the specific implementation of the email management method based on bypass forwarding provided in the embodiment of the present application, it will be described below with reference to the accompanying drawings.

[0144] It should be noted that the key of the original text index is the original text, and the value of the original text index is the email ID of the initial email; the key of the pinyin index is the pinyin, and the value of the pinyin index is the email ID of the initial email; the key of the radical index is the radical, and the value of the radical index is the email ID of the initial email; the key of the radical index is the radical, and the value of the radical index is the email ID of the initial email.

[0145] That is, the original text index is {original text: email ID}, the pinyin index is {pinyin, email ID}, the radical index is {radical, email ID}, and the radical index is {radical, email ID}.

[0146] In an embodiment of the present application, the email retrieval system performs word segmentation on the text content in the initial email (excluding non-text content such as images, audio and video). If Chinese text is involved, when establishing a word segmentation index for the original text of the Chinese text, multiple word segmentation indexes are also established for the pinyin, radicals and components of the Chinese text. The keys of each word segmentation index are the original text, pinyin, radicals and components, and the index value is the ID of the initial email.

[0147] As an example, the mail retrieval system receives the initial mail A forwarded by the mail background bypass, and the mail ID of the initial mail A is 111. It obtains the text content in the initial mail A (for example, the text content "補帖"), first performs word segmentation on the text content, and obtains multiple initial word segmentation results ["補"] and ["帖"]. For each initial word segmentation result, at least one word segmentation index is established. Then establishing at least one word 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 mail retrieval system receives the initial mail B forwarded by the mail background bypass, and the mail ID of the initial mail B is 222. It obtains the text content in the initial mail B (for example, the text content "补贴"), first performs word segmentation on the text content, and obtains multiple initial word segmentation results ["补"] and ["贴"]. For each initial word segmentation result, at least one word segmentation index is established. Then establishing at least one word segmentation index includes {补, 222} {贴, 222} {bǔ, 222} {tiē, 222}, the radical index {衤, 222} {贝, 222}, and the radical index {衤, 222} {贝, 222}.

[0148] Based on the above embodiments, the mail retrieval system stores the obtained word segmentation indexes for retrieving in response to the retrieval requests sent by the management terminal. S27 provided in the embodiments of the present application may include: the mail 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 mail background supports the bypass forwarding function, can forward the original mail to other systems, each mail has a unique mail ID, and the mail management background supports querying mail data from the mail database according to the mail ID and can perform further operations (such as viewing the original mail, querying the recipients of the mail, or deleting the mail, etc.).

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

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

[0152] Then, the SMTP-based mail bypass forwarding function is a common function of mail management systems, and most mail management systems already support it. Retrieving data based on a unique mail ID is a basic function of the system, and most mail management systems support querying specified mails based on mail IDs. The embodiment of the present application reuses the original mail management system, adds a mail retrieval system based on the original mail management system, and uses the existing functions of the original mail management system to achieve the purpose of retrieval and processing, without the need for large-scale transformation of the original associated mail system, thereby reducing the transformation cost.

[0153] In a possible implementation, the mail management system further includes a gateway system. Then, before S21, the method provided in the embodiment of the present application may further include:

[0154] S20, the gateway system checks the initial email and obtains a check result; when the check result indicates that the initial email is not a spam email, the gateway system sends the initial email to the email backend.

[0155] In the embodiment of the present application, the email first arrives at the gateway system in the email management system, and after being checked by the gateway system, the email arrives at the email backend.

[0156] In a possible implementation, the server also includes a mail database, and the method provided in the embodiment of the present application may further include:

[0157] S31, the mail management backend receives a first query request sent by the management terminal;

[0158] S32, the email management backend searches the email database for a first email corresponding to the first query request;

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

[0160] In the embodiment of the present application, the administrator can send a query request to the email management backend through the management terminal to match the email data of all users stored in the email database to the email database.

[0161] In a possible implementation, the email management system further includes a client, the server further includes an email database, and the method provided in the embodiment of the present application further includes:

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

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

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

[0165] In the embodiment of the present application, the user initiates a query request such as viewing emails to the email backend through the client, and the email backend retrieves and returns the user's email data from the email database and displays it to the user through the client.

[0166] In an embodiment of the present application, the email backend supports a bypass forwarding function, which can forward emails to an email retrieval system. Each email has a unique ID identifier. The email management backend supports querying email data in the email database based on the email ID, and can perform further operations (such as viewing the original text of the email, querying the recipient of the email, or deleting the email, etc.).

[0167] In this way, the embodiment of the present application improves on the commonly used architecture of the email management system, adds an email retrieval system, obtains the original email data through bypass forwarding, and establishes a system-wide, user-level word segmentation index, providing a retrieval function that covers all users and non-original stored data.
