For example, some operations / steps can be decomposed, and some operations / steps can be combined or partially combined, so the actual execution order may change according to actual conditions.

[0049] Figure 1 A schematic diagram of an exemplary system architecture to which the technical solution of the embodiments of the present application can be applied is shown.

[0050] like Figure 1 As shown, the system architecture may include terminal devices (such as Figure 1 The embodiment of the present invention is a schematic diagram of a mobile phone 101, a tablet computer 102, a portable computer 103, a desktop computer, etc., a network 104, and a server 105. The network 104 is used to provide a medium for a communication link between the terminal device and the server 105. The network 104 may include various connection types, such as a wired communication link, a wireless communication link, etc.

[0051] It should be understood that Figure 1 The number of terminal devices, networks and servers in the embodiment is only for illustration. According to the implementation requirements, there may be any number of terminal devices, networks and servers. For example, the server 105 may be a server cluster composed of multiple servers.

[0052] The user can use the terminal device to interact with the server 105 through the network 104 to receive or send emails, etc. In one embodiment of the present application, the terminal device (such as one or more of the smart phone 101, the tablet computer 102 and the portable computer 103) can receive emails and obtain the type of the email from the information carried by the email. If the type of the email is a specified type, the type identifier of the email is displayed in the receiving list of the mail client, and the summary information of the email is prohibited from being displayed in the receiving list.

[0053] Based on the above embodiments, it can be known that the email processing method provided in the embodiments of the present application can be executed by a terminal device. Accordingly, the email processing device is generally provided in the terminal device.

[0054] The implementation details of the technical solution of the embodiment of the present application are described in detail below:

[0055] Figure 2 A schematic diagram of a process flow of an email processing method according to an embodiment of the present application is shown. The email processing method can be executed by a terminal device, which can be Figure 1 One or more of the smartphone 101, tablet computer 102, and portable computer 103 shown in FIG. Figure 2 As shown, the email processing method at least includes steps S210 to S230, which are described in detail as follows:

[0056] In step S210, an email is received.

[0057] The content of the email may be any form of information, for example, the content of the email may include but is not limited to information in the form of text, audio, video, and picture.

[0058] In one embodiment of the present application, in response to a request to receive an email sent by a user, the email client can obtain the email to be received from the email server. Specifically, the user can send a request to receive an email by clicking a specific area on the interface (such as a "Get Email" button, etc.), and when the email client receives the request to receive an email, it can obtain the email to be received from the email server.

[0059] In step S220, the type of the email is obtained from the information carried in the email.

[0060] The type of email may be classification information for classifying emails according to the importance of the email content. For example, the type of email may be classified into important emails and ordinary emails, or private emails and public emails, etc. according to the importance of the email content.

[0061] In one embodiment of the present application, the type of an email may be associated with the email. When a mail client receives an email from a mail server, the type of the email may be sent to the mail client together with the email so that the mail client can identify the type of the email.

[0062] In step S230, if the type of the email is a specified type, the type identifier of the email is displayed in the recipient list of the mail client, and the summary information of the email is prohibited from being displayed in the recipient list.

[0063] The specified type may be an email with important content, for example, an important email or a private email, etc. If the type of the email is the specified type, it means that the email content of the email needs to be protected to prevent leakage of the email content of the email.

[0064] The type identifier may be identification information corresponding to the type of the email. In one example of the present application, the type identifier may be a graphic identifier, such as a red flag corresponding to an important email, a yellow flag corresponding to an ordinary email, etc.; in another example of the present application, the type identifier may also be a text identifier, such as "Important Email" corresponding to an important email, "Ordinary Email" corresponding to an ordinary email, etc.; in other examples of the present application, the type identifier may also be a letter identifier or a number identifier, etc., and the present application does not make any special restrictions on this.

[0065] The summary information may be summary information of the email content. For example, the summary information of the email may be the subject of the email, the file name of the attachment, or keyword information extracted from the email content.

[0066] In this embodiment, if it is detected that the type of the email received by the mail client is a specified type, the type identifier of the email is displayed at the position corresponding to the email in the mail list of the mail client, and the summary information of the email is prohibited from being displayed at the position corresponding to the email in the mail list.

[0067] exist Figure 2In the embodiment shown, after receiving an email, the email client obtains the type of the email from the information carried in the email and detects the type of the email. If the type of the email is a specified type, it means that the content of the email needs to be protected, so the type identifier of the email is displayed in the email client's receiving list to remind the user of the importance of the email content and to take protective measures to prevent leakage of the email content. In addition, the summary information of the email is prohibited from being displayed in the receiving list, so that the content of the email can be protected when the user does not view the content of the email to prevent the content of the email from being leaked due to the summary information of the email.

[0068] based on Figure 2 The embodiment shown, Figure 3 The method for processing an email according to an embodiment of the present application further includes a flowchart of viewing an email of a specified type. Figure 3 In the illustrated embodiment, if the type of the email is the specified type, the email processing method at least further includes steps S310 to S330, which are described in detail as follows:

[0069] In step S310, when a request to view the email is received, the email content of the email is pulled from the email server corresponding to the email, and the email content is encrypted using an encryption key.

[0070] Among them, the mail server can be a server that can receive and deliver emails to realize email transmission between mail clients. It should be noted that, according to actual implementation needs, in one example of the present application, the mail server can be a server that can simultaneously provide the functions of receiving and delivering emails to realize email transmission between mail clients; in another example of the present application, the mail server can also include two or more servers, and different servers have different functions. For example, the mail server can include a mail sending server and a mail receiving server. The mail sending server can receive emails from the mail client and deliver them to the mail receiving server. The mail receiving server can receive emails delivered by the mail sending server and send them to the receiving mail client of the email, and so on.

[0071] The email content of an email may be content related to the information transmitted by the email, for example, the email content may include but is not limited to the body of the email and attachments, etc. It should be understood that the email content may be information in any form, for example, the email content may include but is not limited to information in the form of text, video, picture, and audio.

[0072] In this embodiment, when a request to view an email of a specified type is received, the email client can pull the email content of the email from the email server corresponding to the email in real time to avoid the email content being directly stored in the email client and causing the email content to be leaked. The email server can encrypt the email content of the email using an encryption key, and the email needs to be decrypted before the email content can be viewed, which can prevent the email content from being leaked when others obtain the email (such as when the pull is wrong). In step S320, the email content is decrypted based on the stored decryption key.

[0073] In one embodiment of the present application, the encryption key may be the identity information of the recipient of the email, for example, the decryption key may be the account number and / or password of the recipient of the email, etc. The decryption key may be the identity information of the current login account of the email client, for example, the decryption key may be the account number and / or password of the current login account of the email client, etc. Therefore, when the encryption key and the decryption key are the same, it means that the recipient of the email and the current login account of the email client are the same user, and the email transmission is correct, so the email content of the email can be decrypted without causing the email content to be leaked.

[0074] In one example of the present application, the email client can directly obtain the decryption key from the identity information of the currently logged-in account to improve the efficiency of the decryption process; in another example of the present application, when the email content needs to be decrypted, the email client can also obtain the decryption key from the user in real time. The user can input the decryption key through the input device of the terminal device (such as a keyboard, a touch screen, etc.), and the email client will then decrypt the email content according to the decryption key entered by the user, which can prevent others from maliciously stealing the account to obtain the email content of the email, thereby ensuring the security of the email content of the email.

[0075] It should be understood that "and / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent three situations: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the associated objects before and after are in an "or" relationship.

[0076] In step S330, if the email content is decrypted successfully, the email content is displayed.

[0077] In this embodiment, if the encryption key and the decryption key correspond to each other, that is, the recipient of the email and the current login account of the email client are the same user, the email content can be successfully decrypted to display the email content.

[0078] exist Figure 3 In the illustrated embodiment, upon receiving a request to view an email of a specified type, the email client can pull the email content of the email from the email server corresponding to the email in real time, wherein the email content has been encrypted by an encryption key. By pulling the email content of the email in real time, it is possible to prevent the email content of the specified type of email stored in the email client, thereby preventing the email content of the email from being leaked. Furthermore, by encrypting the email content of the email, it is possible to prevent the email content from being leaked even if it is pulled incorrectly, thereby ensuring the security of the email content.

[0079] In one embodiment of the present application, each time an email of a specified type is viewed, the email is decrypted, and when the viewing is completed, the email is restored to an encrypted state to prevent others from viewing the email content of the specified type through the user's email client, thereby avoiding leakage of the email content.

[0080] In another embodiment of the present application, the email of a specified type may be decrypted when the email is viewed for the first time. After the viewing is completed, the email of the specified type is no longer restored to the encrypted state, thereby improving the viewing efficiency of the email when it is viewed again and improving the user experience.

[0081] based on Figure 2 and Figure 3 The embodiment shown, Figure 4 The method for processing an email according to an embodiment of the present application further includes a flowchart of extracting email content. Figure 4 In the illustrated embodiment, pulling the email content of the email from the email server corresponding to the email includes at least steps S410 to S430, which are described in detail as follows:

[0082] In step S410, the identity information of the mail client is encrypted by using the certificate issued by the mail server to obtain encrypted identity information.

[0083] The certificate may be information issued by the mail server and used to indicate that the mail client has passed security authentication. If the mail client has a certificate issued by the mail server, it means that the mail client has passed security authentication, and the mail client is allowed to pull the mail content of the specified type of email.

[0084] The identity information of the mail client may be information related to the mail client. For example, the identity information of the mail client may include but is not limited to the name and version number of the mail client.

[0085] In this embodiment, the mail client encrypts the identity information of the mail client according to the certificate issued by the mail server to obtain the encrypted identity information of the mail client, so that the certificate owned by the mail client is associated with the identity information of the mail client.

[0086] In step S420, a pull request for the email is generated, wherein the pull request includes the encrypted identity information.

[0087] In this embodiment, a pull request for the email is generated based on the encrypted identity information of the email client. It should be noted that the pull request may include identification information of the email that the email client needs to pull to avoid incorrect pulling of the email. In one example of the present application, the identification information of the email may be the number information of the email, such as No.123456, etc.; in another example of the present application, the identification information of the email may also be information generated based on the sending and receiving information of the email (such as sender and receiver information, sending and receiving time information, etc.), and the present application does not make any special limitation on this.

[0088] In step S430, the pull request is sent to the mail server, and the mail content returned by the mail server after verifying the encrypted identity information is received.

[0089] In this embodiment, the mail client sends a pull request to the mail server to pull the email content of the email from the mail server. After receiving the pull request, the mail server obtains the encrypted identity information of the mail client from the pull request to verify the encrypted identity information of the mail client and determine whether the mail client meets the requirements for protecting the email content of the specified type of email. If the verification is successful, the mail server returns the email content of the email that the mail client wants to pull to the mail client, and the mail client receives the email content returned by the mail server and displays it; if the verification fails, that is, the mail client does not meet the requirements for protecting the email content of the specified type of email, the mail server does not return the email content to the mail client.

[0090] In one embodiment of the present application, after receiving the encrypted identity information sent by the mail client, the mail server decrypts the encrypted identity information to obtain the identity information of the mail client. The mail server matches the identity information of the mail client with a set client set, wherein the client set includes the identity information of the mail client that has passed the security authentication. If the identity information of the mail client received by the mail server exists in the client set, it means that the mail client has passed the authentication and can pull the email content of the specified type of email.

[0091] It should be noted that if the email client is a web version, the email client should be prohibited from pulling email contents of specified types of emails from the email server, because the web version of the email client runs based on the browser, and the plug-ins or functions of the browser may cause the email contents of specified types of emails to be leaked, making it difficult to protect the email contents of specified types of emails.

[0092] exist Figure 4 In the illustrated embodiment, when the mail client pulls the content of a specified type of email, a pull request for the email is generated based on the encrypted identity information of the mail client, and the pull request is sent to the mail server. The mail server obtains the encrypted identity information of the mail client based on the received pull request, and verifies the encrypted identity information. If the verification is successful, the email content of the email is returned to the mail client, which can prevent the email content of the specified type of email from being pulled by a mail client that does not meet the requirements for protecting the email content, resulting in the leakage of the email content.

[0093] In one embodiment of the present application, the mail client can be security authenticated according to the functions of the mail client. If the mail client does not have the function of protecting the mail content of the email (for example, displaying the type identification of the specified type of email in the mail client's receiving list, and prohibiting the display of the summary information of the specified type of email in the receiving list, etc.), it means that the mail client cannot protect the mail content of the specified type of email, so the mail client cannot pass the security authentication and cannot pull the content of the specified type of email from the mail server. If the mail client passes the security authentication, the mail server issues a certificate to the mail client.

[0094] It should be noted that since the functions of the same version of mail clients are the same, security authentication can be performed only for different versions of mail clients. The certificate issued by the mail server is valid for the same version of mail clients, and there is no need to perform security authentication repeatedly.

[0095] based on Figure 2 and Figure 3 The embodiment shown, Figure 5 A schematic diagram of a process for displaying email content is shown in the email processing method according to an embodiment of the present application. Figure 5 In the illustrated embodiment, displaying the email content at least includes steps S510 to S520, which are described in detail as follows:

[0096] In step S510, watermark prompt information is generated according to the identity information of the current account of the email client.

[0097] The current account may be the account currently logged in by the mail client, and the information of the current account may be identity information related to the current account. For example, the information of the current account may be the name, nickname or account number of the user corresponding to the current account.

[0098] The watermark prompt information may be information used to prompt the user to protect the email content of the email of a specified type that the user is viewing.

[0099] In this embodiment, when a request to view an email of a specified type is received, information of the current account of the email client is obtained, and watermark prompt information is generated based on the information of the current account. For example, when user A is viewing an email of a specified type, a watermark prompt information "XXX is reading this email, please pay attention to information security matters" is generated based on user A's identity information (such as user A's name), etc.

[0100] In step S520, when displaying the email content, the watermark prompt information is displayed on the email content display interface.

[0101] The mail content display interface may be an interface for displaying the body text or attachments of an email.

[0102] In this embodiment, when a user is viewing the email content of a specified type of email, a watermark prompt information is displayed at any specified displayable position on the email content display interface. The watermark prompt information can remind the user of the importance of the email content being viewed and require the user to protect the email content, such as prohibiting the user from forwarding, replying, downloading or taking screenshots of the email content, etc., to ensure the security of the email content.

[0103] In one embodiment of the present application, an expiration date may be set for a specified type of email, and the watermark prompt information may include the expiration date prompt information for the specified type of email. For example, the expiration date prompt information may be "This email will expire in 7 days", etc., to remind the user of the expiration date of the specified type of email, making it easier for the user to control the expiration date.

[0104] based on Figure 2 and Figure 3 The embodiment shown, Figure 6 A schematic diagram of a process for obtaining operation data is shown in a method for processing an email according to an embodiment of the present application. Figure 6 In the illustrated embodiment, the method for processing an email for obtaining operation data includes at least steps S610 to S630, which are described in detail as follows:

[0105] In step S610, during the process of displaying the email content, operation data for the email content is detected.

[0106] The operation data for the email content may be data related to the operation of the user when viewing the email content.

[0107] In this embodiment, when a user is viewing the content of an email, the email client can detect the user's operations on the email content (such as viewing, copying, or taking screenshots, etc.) and obtain data related to the user's operations (such as the time when the user viewed the email content, the IP address, or the number of times the user viewed the same specified type of email, etc.).

[0108] In step S620, if the operation data contains risk data, risk warning information is generated.

[0109] Among them, risk data can be operational data that makes the email content at risk of leakage. For example, when viewing the email content of a specified type of email, the email client detects operations such as screenshots, copies, or multiple views, or the current IP address is not a commonly used address, etc., which indicates that the risk of leakage of the email content is high.

[0110] The risk warning information may be information for warning the sender of an email of a specified type.

[0111] In this embodiment, based on the operation data on the email content detected by the email client, if the operation data on the email content contains risk data, risk warning information is generated based on the risk data, wherein the risk warning information may include but is not limited to the type of operation (such as screenshot, copy, etc.), the time of the operation, the number of operations, etc.

[0112] In step S630, the risk warning information is sent to the sender of the email.

[0113] In one embodiment of the present application, the risk warning information can be sent to the sender of the email in the form of an email, that is, the risk warning information is sent to the sender's mailbox for review, thereby realizing a risk warning; in another embodiment of the present application, the risk warning information can also be sent to the sender's phone number (for example, in the form of text messages), social account (for example, in the form of QQ messages or WeChat messages, etc.) or other contact methods for communication, so that the sender of the email can timely manage the leakage risk of specified types of emails without logging into the mailbox.

[0114] exist Figure 6 In the illustrated embodiment, it is detected whether the operation data of the email content of a specified type of email contains risk data. If the operation data contains risk data, a corresponding risk warning information is generated, and then the risk warning information is sent to the sender of the email, so that the sender of the email can promptly manage the leakage risk of the specified type of email, and promptly know who, when and what operation caused the increased leakage risk of the specified type of email.

[0115] based on Figure 6 In the embodiment shown, in one embodiment of the present application, the email processing method further includes:

[0116] In response to a request to view the operation data of the sent email of the specified type, the operation data related to the sent email of the specified type is displayed on the interface.

[0117] The sent emails of the specified type may be emails of the specified type that have been sent historically by the current account of the mail client.

[0118] In this embodiment, when a request for viewing risk data of a sent email of a specified type is received, the operation data related to the sent email of the specified type is displayed on the interface for the user to view, so that the user can perform leakage risk control on the email of the specified type that he has sent. For example, as shown in Table 1:

[0119]

[0120]

[0121] Table 1 Operation data information table

[0122] As shown in the above table, an operation data information table is generated based on the operation data related to the specified type of email sent by the user, and the operation data information table may include but is not limited to the email / attachment name, the recipient of the email, the viewing time, the viewing location, and the potential security risk, etc. In this embodiment, different potential security risk levels can be set according to different operations of the recipient. For example, if the user normally views the specified type of email, the potential security risk level is low; if the user views the specified type of email at an uncommon address, the potential security risk level is high, and so on.

[0123] based on Figure 2 and Figure 3 The embodiment shown, Figure 7 A schematic diagram of a process of viewing emails is shown in the email processing method according to an embodiment of the present application. Figure 7 In the illustrated embodiment, the email processing method for viewing emails at least includes steps S710 to S720, which are described in detail as follows:

[0124] In step S710, during the process of displaying the email content, downloading, forwarding or replying to the email content is prohibited.

[0125] In this embodiment, when the email content of a specified type of email is displayed, the user is prohibited from downloading, forwarding or replying to the email content, thereby preventing the email content of the specified type from further spreading, thereby reducing the risk of leakage of the email content.

[0126] In one embodiment of the present application, function buttons such as download, forward, and reply may not be displayed on the content display interface of a specified type of email, so that users viewing the specified type of email cannot spread the email content of the email, thereby reducing the risk of leakage of the email content and thereby ensuring the security of the email content.

[0127] In step S720, upon receiving an instruction indicating that the viewing of the email is complete, the cache information of the email is deleted.

[0128] In one embodiment of the present application, the detection of whether the email is viewed completely can be performed by detecting whether a specific area (such as a "close" button, etc.) on the email content display interface is triggered to determine whether the viewing is complete. If it is detected that the specific area on the email content display interface is triggered, it indicates that the viewing is complete, and the email content display interface of the specified type of email is closed.

[0129] When receiving the instruction to complete the email viewing, the cache information related to the email is deleted. It should be understood that the cache information related to the email may include the cache information of the email in the terminal device and the cache information of the email in the mail client, etc.

[0130] exist Figure 7 In the illustrated embodiment, after finishing viewing an email of a specified type, the cached information related to the email is deleted, thereby preventing the user or others from obtaining the content of the email through the cached information of the terminal device or email client, thereby prohibiting the user or others from saving or disseminating the email content of the email, thereby reducing the risk of leakage of the email content of the specified type of email.

[0131] based on Figure 2 In the embodiment shown, in one embodiment of the present application, the information carried by the email includes the validity period of the email, and the email processing method further includes:

[0132] If it is determined that the email has expired according to the validity period of the email, a prompt message indicating that the email has expired is displayed in the recipient list.

[0133] The validity period may be a period during which the email content of the specified type of email is allowed to be viewed, for example, the validity period of the email may be 3 days, 5 days or 7 days, etc. If the validity period of the specified type of email has expired, the email content of the expired specified type of email is prohibited from being viewed, so as to protect the email content of the email.

[0134] In this embodiment, if it is determined that the email has expired based on the validity period of the email, a prompt message indicating that the email has expired is displayed at the position corresponding to the email in the recipient list of the email client, such as "This email has expired", etc., so that the recipient of the email can know that the email has expired without viewing the email, thereby facilitating the recipient to know the current status of the email.

[0135] In one embodiment of the present application, the existence time of an email of a specified type may be compared with the validity period of the email. If the existence time of the email is greater than the validity period of the email, it indicates that the email has expired.

[0136] In one example of the present application, the existence time of an email can be calculated from the time the email is sent. For example, the sender of the email sends the email at 17:00 on 2019.08.16, then the existence time of the email is calculated from 17:00 on 2019.08.16; in another embodiment of the present application, the existence time of the email can also be calculated from the time when the email is received by the recipient. For example, the sender of the email sends the email at 17:00 on 2019.08.16, but the recipient of the email receives the email at 19:00 on 2019.08.16, then the existence time of the email is calculated from 19:00 on 2019.08.16.

[0137] The current time can be subtracted from the sending timestamp or receiving timestamp of the email to obtain the existence time of the email. For example, if the current time is 19:00 on 2019.09.20 and the receiving timestamp of the email is 19:00 on 2019.09.16, then the existence time of the email is four days (20-16=4), and the corresponding validity period of the email is 3 days. Since 4>3, the email has expired.

[0138] Based on the above embodiment, in one embodiment of the present application, the email processing method further includes:

[0139] If the email has expired, when a request to view the email is received, it is prohibited to send a pull request for the email to the email client, and an expiration prompt message is displayed on the email content display interface of the email, and the content and summary of the email are not displayed.

[0140] Among them, the summary of the email can be the summary information of the email content. Based on the summary of the email, certain information about the email content can be obtained. For example, the summary of the email can be the subject of the email, the file name of the attachment, etc. The summary of the email can also be keyword information extracted from the content of the email, and so on.

[0141] In this embodiment, if it is detected that an email has expired, then upon receiving a request for an expired email, the email client is prohibited from sending a pull request for the expired email, so that the email client cannot obtain the email content of the expired email of the specified type from the email server, thereby protecting the email content of the expired email of the specified type.

[0142] The expired email message (e.g., "This email has expired") is displayed on the email content display interface of the expired email, so that the user can know the status information of the email, that is, whether the email has expired. The email content and summary are not displayed on the email content display interface of the email, so that the user can no longer obtain the email content of the expired email, so as to protect the email content of the expired email and prevent the email content of the expired email from being leaked.

[0143] Based on the above embodiment, in another embodiment of the present application, the email processing method further includes:

[0144] If the email has expired, when a request to view the email is received, an expiration reminder message is displayed on the email content display interface of the email according to the indication information returned by the mail server after the email has expired, and the content and summary of the email are not displayed.

[0145] The indication information may be information that the mail server indicates to the mail client that the email of the specified type has expired, and the indication information may include information about the expired email of the specified type.

[0146] In this embodiment, if a request to view an expired email is received, a pull request for the email is sent to the mail server. The mail server returns an indication that the email has expired to the mail client based on the pull request of the mail client. The mail client displays an expiration prompt message on the email content display interface of the email based on the indication message to prompt the user with status information of the email, and the content and summary of the email are not displayed on the email content display interface of the email to prevent the user from obtaining the email content of the expired email, thereby protecting the email content of the expired email.

[0147] In one embodiment of the present application, when an email of a specified type has expired, the mail server storing the email may delete the email content of the email and save the sending and receiving record information of the email, wherein the sending and receiving record information of the email may be information generated based on the sender and receiver information, sending and receiving time information and summary of the email, and the sending and receiving record information may include but is not limited to the sender information, receiver information, sending time, receiving time and summary of the email, etc.

[0148] Deleting the email content of the expired email of the specified type from the email server can prevent the email content of the specified type from being leaked under special circumstances (such as when the email server is maliciously hacked, etc.). And saving the sending and receiving record information of the email can be used as the basis for the existence of the email. Compared with deleting all the information of the email of the specified type, a certain amount of information of the email can be obtained based on the stored sending and receiving record information, which is convenient for subsequent litigation evidence, etc.

[0149] After the mail server deletes the email content of the expired email, it can generate indication information that the email has been deleted. After receiving the pull request for the email sent by the email client, it returns the indication information that the email has been deleted to the email client. According to the indication information, the email client can display the expiration prompt information on the email content display interface of the email, but does not display the email content and summary of the email.

[0150] based on Figure 2 The embodiment shown, Figure 8 A schematic diagram of a process of creating an email is shown in the email processing method according to an embodiment of the present application. Figure 8 In the illustrated embodiment, the email processing method for creating an email includes at least steps S810 to S830, which are described in detail as follows:

[0151] In step S810, if a request for creating an email of a specified type is received, an editing interface for the email validity period is displayed.

[0152] The editing interface of the validity period of the email may be an editing interface for editing the validity period of an email of a specified type. The user may edit the validity period of an email of a specified type in the editing interface.

[0153] In one embodiment of the present application, if a request to create an email is received, a mail type list is displayed on the interface, wherein the mail type list may include information on the types of emails that can be created, for example, the mail type list may include mailbox types such as important mail, ordinary mail, private mail, and public mail. The user can select from the mail type list to create an email of the corresponding type.

[0154] If the user selects a specified type (such as important emails or private emails, etc.) in the email type list, a creation request for the specified type of email is sent. After receiving the creation request, the email client displays an editing interface for the email validity period on the interface for the user to edit the validity period of the specified type of email.

[0155] In step S820, the validity period information of the email input in the editing interface is received.

[0156] In one embodiment of the present application, the editing interface of the email validity period may include multiple validity periods for users to select (for example, 1 day, 3 days, 5 days or 7 days, etc.), and the user can determine the validity period of the email by clicking on the corresponding validity period. For example, if the user clicks on the validity period of "1 day", the validity period of the specified type of email created is determined to be 1 day, and so on.

[0157] In another embodiment of the present application, the editing interface of the validity period of the email may also include a validity period input box for the user to input, and the user may enter the required validity period in the validity period input box to determine the validity period of the created email. For example, if the user enters "3" in the validity period input box, the validity period of the created email is determined to be 3 days, and so on.

[0158] In step S830, the designated type and the validity period information are added to the created email.

[0159] In one embodiment of the present application, the mail type and validity period information can be associated with the created email, and identification information can be generated according to the mail type and validity period information selected by the user, and the identification information is added to the data stream of the created email, so that the identification information can be transmitted together with the created email. During the transmission process, the mail server and the mail client receiving the email can determine the mail type and validity period of the email according to the identification information to protect the mail content of the specified type of email. For example, the letter corresponding to "important mail" is A, and the validity period of the email (for example, 3 days) is converted into a four-digit binary sequence, and the identification information of the email is generated according to the letter and the binary sequence, so the identification information of the email with a validity period of three days and a mail type of "important mail" can be A0011, and the identification information is added to the data stream of the email, so that in subsequent transmissions, the mail type and validity period of the transmitted email can be determined according to the identification information.

[0160] exist Figure 8 In the illustrated embodiment, in response to a request to create an email of a specified type, an editing interface for the email validity period is displayed, and the user can enter the validity period information of the email to be created in the editing interface for the email validity period, and then add the email type and validity period of the email to the created email to facilitate identification in subsequent transmissions.

[0161] based on Figure 8 The embodiment shown, Fig. 9 A schematic diagram of a process of sending an email is shown in the method for processing an email according to an embodiment of the present application. Fig. 9 In the embodiment shown, the email processing method for sending an email includes at least steps S910 to S920, which are described in detail as follows:

[0162] In step S910, if a request to send the created email is received, the legitimacy of the mail server corresponding to the created email is verified.

[0163] The legitimacy verification may be a verification process for detecting whether the mail server meets the requirement for protecting the mail content of a specified type of email.

[0164] In this embodiment, when a request to send an email of a specified type is received, in order to protect the email content of the specified type of email, it is necessary to verify the legitimacy of the mail server corresponding to the email to determine whether the mail server corresponding to the email meets the requirements for protecting the email content of the specified type of email. It should be understood that the mail server corresponding to the email can be the mail server corresponding to the recipient of the email, and the recipient of the email can pull the email from its corresponding mail server. According to actual implementation needs, mailbox users within a certain range such as the same region (such as a province, city, etc.) or the same enterprise can be divided into the same mail server, and this application does not make special restrictions on this.

[0165] In step S920, if the legitimacy verification of the mail server is passed, the created email is sent to the mail server for delivery by the mail server.

[0166] In this embodiment, if the mail server passes the legitimacy verification, it means that the mail server meets the requirements for protecting the email content of the specified type of email, so the created email of the specified type can be sent to the mail server for delivery through the mail server.

[0167] exist Fig. 9 In the embodiment shown, when sending an email of a specified type, the mail server corresponding to the email is verified for legitimacy, and it can be determined whether the mail server meets the requirements for protecting the email content of the specified type of email. If the mail server passes the legitimacy verification, the created email is sent to the mail server for delivery. This can prevent the email of the specified type from being delivered by a mail server that has not passed the legitimacy verification, thereby reducing the risk of leakage of the email content of the specified type of email.

[0168] based on Fig. 9 The embodiment shown, Fig.10 A schematic diagram of a process for verifying the legitimacy of a mail server is shown in the method for processing an email according to an embodiment of the present application. Fig.10 In the embodiment shown, the email processing method performs legitimacy verification on the email server, which includes at least steps S1010 to S1030, which are described in detail as follows:

[0169] In step S1010, identification information of the mail server is obtained.

[0170] The identification information of the mail server may be information uniquely corresponding to the mail server. For example, the identification information of the mail server may include but is not limited to the domain name, IP address and other information related to the identity of the mail server.

[0171] In this embodiment, the mail server corresponding to the email can be determined based on the recipient information of the created email of a specified type (such as the recipient's email account, etc.), and the identification information of the mail server can be obtained.

[0172] In step S1020, the identification information of the mail server is matched with a set mail server set, wherein the mail server set includes the identification information of the authenticated mail servers.

[0173] The mail server set may be pre-set and contain identification information of authenticated mail servers, that is, mail servers whose identification information exists in the mail server set all meet the requirement of protecting the mail content of designated types of emails.

[0174] In this embodiment, the identification information of the mail server may be matched one by one with the identification information in the mail server set to determine whether the identification information of the mail server exists in the mail server set.

[0175] In step S1030, if the mail server set includes the identification information of the mail server, it is determined that the legitimacy verification of the mail server is passed.

[0176] In this embodiment, the identification information of the mail server is matched with the identification information of the authenticated mail servers contained in the mail server set. If the identification information of the mail server is the same as any identification information contained in the mail server, it means that the mail server set contains the identification information of the mail server, that is, the mail server has passed the authentication, and therefore the created email of the specified type can be sent to the mail server for delivery.

[0177] exist Fig.10 In the illustrated embodiment, the identification information of the authenticated mail servers is collated to generate a mail server set. When the legitimacy of the mail server is verified, the identification information of the mail server can be matched with the identification information contained in the mail server set. If the match is successful, it is determined that the mail server has passed the authentication and meets the requirements for protecting the specified type of emails. The security of the mail server corresponding to the specified type of emails can be guaranteed, and the verification is performed according to the pre-set mail server set, without the need for cumbersome verification steps, thereby improving the verification efficiency.

[0178] Based on the technical solution of the above embodiment, the following introduces a specific application scenario of an embodiment of the present application:

[0179] Please refer to Fig.11 , Fig.11 The following is a schematic diagram showing an application scenario of a method for processing an email according to an embodiment of the present application. Fig.11 In the application scenario shown, a user can create an email of a specified type through an email client 1110. When the user needs to send an email of the specified type, the email of the specified type can be first sent to the email sending server 1120, and the email sending server 1120 delivers the email to the email receiving server. During the delivery process of the email sending server, the email sending server verifies the legitimacy of the email receiving server. If the email receiving server is a credit email receiving server 1130 (i.e., a certified email server), it is allowed to deliver emails of the specified type to the credit email receiving server 1130. If the email receiving server is an ordinary email receiving server 1140 (i.e., an uncertified email server), it is prohibited to deliver emails of the specified type to the ordinary email receiving server 1140, so as to prevent the email content of the email of the specified type from being leaked due to the low security of the email receiving server.

[0180] When the trusted mail receiving server 1130 receives an email of a specified type, the mail client may request to pull the email content of the email of the specified type from the trusted mail receiving server 1130. When receiving a pull request for an email of a specified type from a mail client, the trusted mail receiving server 1130 may verify the mail client according to the information of the mail client that initiated the pull request (i.e., the identity information of the mail client). If the mail client is a trusted mail client 1150 (i.e., a mail client that has passed the security authentication), the trusted mail client 1150 is allowed to pull the email content of the email of the specified type from the trusted mail server 1130; if the mail client is an untrusted mail client 1160 (i.e., a mail client that has not passed the security authentication), the untrusted mail client 1160 is prohibited from pulling the content of the email of the specified type from the trusted mail receiving server 1130. If the trusted mail receiving server 1130 receives a request for pulling emails of a specified type sent by the Web version mail client 1170, the Web version mail client 1170 is prohibited from pulling the email content of the specified type of email from the trusted mail receiving server 1130. By verifying the mail client, the mail client can meet the requirement for protecting the email content of the specified type of email, thereby ensuring the security of the email content of the specified type of email.

[0181] After the mail sending server 1120 delivers the specified type of email, the delivery status of the email can be reported to the security monitoring server 1180, which will record and store it for subsequent legal risks and litigation. In addition, the credit mail client 1150 can collect the operation data of the user when viewing the email content of the specified type of email, and report the operation data to the security monitoring server 1180 for storage. The security monitoring management platform 1190 can communicate with the security monitoring server 1180, and the user can query the operation data stored in the security monitoring server 1180 through the security monitoring management platform 1190 to know the operation data related to the specified type of email sent by the user, so as to facilitate the user to perform risk management and control of the specified type of email.

[0182] Based on the technical solution of the above embodiment, Figures 12 to 18 FIG. 1 is a schematic diagram of a terminal interface of an email processing method applied to an embodiment of the present application. Fig.12 As shown, when a user request to create an email is received, an email type list 1210 is displayed on the interface, and the user can create an email of the corresponding email type by clicking the corresponding email type on the email type list 1210 (for example, clicking "Important Email").

[0183] like Fig.13 As shown, in response to the user selecting "Important Email" in the email type list 1210, it is determined that the email type to be created by the user is important email (as shown in 1310 in the figure). Since "Important Email" is an email of a specified type, an editing interface 1320 for the email validity period is displayed on the interface. The user can determine the validity period of the created email by clicking on the corresponding validity period. For example, if the user clicks "Four Days", the validity period of the created email is four days, and so on.

[0184] like Fig.14 As shown, when the mail client receives an email of a specified type, the type identifier of the email is displayed in the position corresponding to the email in the recipient list (for example, as shown in 1410 in the figure, the type identifier of the email of the specified type is displayed as "internal sensitive email"). The user can know the importance of the email based on the type identifier without viewing the email content of the email. In addition, the summary information of the email (such as the subject of the email, etc.) is prohibited from being displayed in the recipient list, so that the user cannot obtain information related to the email content of the email from the summary information of the email, thereby ensuring the security of the email content of the email. When the email of the specified type has expired, the type identifier can also be displayed accordingly (for example, as shown in 1420 in the figure, the type identifier of the expired email of the specified type is displayed as "internal sensitive email has expired"), so that the user can understand the status information of the email of the specified type in the recipient list, that is, whether the email has expired.

[0185] like Fig.15 and Fig.16 As shown, when a viewing request for a specified type of email is received, a watermark prompt information is generated according to the information of the current account of the email client, and the watermark prompt information is displayed on the email content display interface (such as the text display interface or the attachment preview interface, etc.) of the specified type of email. For example, as shown in 1510 and 1610 in the figure, the watermark prompt information can be "XXX is reading this email, please pay attention to information security matters" to remind the user of the importance of the email being viewed, and the user should protect the email content of the email. It should be noted that the watermark prompt information can also include a validity period prompt for the specified type of email. For example, as shown in 1520 in the figure, the validity period prompt for the email (such as "the email will expire in 7 days") can be displayed on the email content display interface of the specified type of email, so that the user can understand the validity period of the specified type of electronic time when viewing the specified type of email.

[0186] like Fig.17and Fig.18 As shown, when an email of a specified type has expired, when a request to view an email of the specified type that has expired is received, an expiration prompt message is displayed on the email content display interface of the email of the specified type that has expired (for example, as shown in 1710 and 1810 in the figure, "The email has expired and cannot be read" or "The attachment has expired and cannot be viewed" is displayed on the email content display interface), and the email content and summary (as shown in 1720 in the figure) of the email are not displayed. This makes it impossible for the user to obtain the email content of the email of the specified type that has expired, so as to protect the email content of the email.

[0187] The following describes an embodiment of the device of the present application, which can be used to execute the method for processing emails in the above embodiment of the present application.
