Flow chart of the method of historical mail. detailed description

The present invention will be further described in detail below with reference to the accompanying drawings and embodiments in order to make the present invention. It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

As shown in FIG. 1, the present invention provides a method for offline browsing history mail, which is applied to a terminal having an email client, including:

5100. Obtain a mail from a mail server to a mail database of the terminal;

5101. Set up a backup mail folder in the storage device, and back up the mail in the mail database to the backup mail folder.

In a preferred embodiment, the mail database is located under the system directory email dedicated path of the terminal. For example, the mail database described here includes two sub-databases, one for storing information such as headers and attachments of the mail, and the other for storing the body of the mail. And each database has a corresponding table for storing the specific information of the mail.

As shown in Figure 3, when the terminal receives the mail from the mail server, the terminal stores the mail in the mail database, and the corresponding mail database is stored in the terminal mail system directory, mainly including the database A and the mail storing the mail header and the attachment information. The database B of the text, and the database A contains two tables: Tablel is used to store the header, Table2 is used to store the attachment of each email, if there is no attachment, it is empty; Database B contains a table Table3, dedicated to The body of the mail.

Each message has a unique ID number, which is also associated with Tablel and Table2. And the ID in Table3 corresponds to the MessageKey. When the user initiates the mail backup, according to the ID of the selected mail, the same ID is found in the three tables of the mail database. If found, the corresponding key field in Table 1 is taken (for example: From\To\Cc\Bcc , Subject, X_nikename, etc.), the corresponding key fields in Table3 (for example: HtmlContentVTextContent, etc.) and the corresponding key fields in Table2 (for example: FileName, Size, etc.) to assemble them into a new text format, The new text naming method is: From: ... ( Subject: ...+Date ), and finally save the attachment in the same path as the mail text according to the storage location of the attachment in Table 2, the command mode is: Attachment— From: ... ( Subject: ...+Date ).

In the preferred embodiment, before backing up the mail in the mail database to the backup mail folder, the method includes:

According to the user's mail backup command, some or all of the mails are backed up from the mail database to the backup mail folder.

If you choose to take part of the mail backup, you only need to back up the mails required by the user from the mail database to the backup mail folder. If you select all mail backups, all the mails in the mail database will be backed up to the backup mail folder.

According to the user's predefined mail backup rules, the corresponding mail is backed up from the mail database to the backup mail folder.

For example, the user can pre-form the mail backup rule to back up the latest received mail to the backup mail folder. When the terminal accesses the Internet, once the new mail is received, the mail received by the letter is backed up to the backup mail in time. folder. Alternatively, when the user can pre-mail the mail in the mail database to the backup mail folder in a preferred embodiment sent by a contact in advance, the user includes: Here is based on security considerations. Once the mail is backed up to the storage device, the user needs to open the backup mail folder on the storage device to view the corresponding mail. Then, the corresponding security certificate information needs to be input to verify the authenticity of the user and prevent others from being Stealing email messages.

In another preferred embodiment, when backing up the mail in the mail database to the backup mail folder, the method includes:

Here is also based on security considerations, that is, in order to better protect the user's email security, when the user operates the storage device and opens the corresponding email, it is necessary to input the password that meets the requirements to successfully open the email, and the user who cannot open the password cannot be mastered. The backup mail folder cannot be opened smoothly, so that the security of the mail can be protected to some extent.

Preferably, the open password is sender information of the corresponding mail. For example: if the mail stored in the backup mail folder is Zhang San's mail, the opening password setting of the backup mail folder can be set by using Zhang's nickname, real name, or E-mail address information, so that It is convenient for users to remember the opening password of each backup mail folder.

In a preferred embodiment, the method for offline browsing history mail further includes:

When performing the operation on the backup mail folder, the terminal detects the network. If the network exists, the user is prompted to select the email client to perform the operation on the corresponding mail. If the network does not exist, the operation of the backup mail folder is directly performed.

In an implementation manner, if the terminal detects that the network does not exist, the operation of the backup mail folder is performed according to the security certificate information.

In another implementation manner, if the terminal detects that the network does not exist, the operation of the backup mail folder is performed according to the open password. When the number of times the password is turned on is more than the preset restart threshold, the operation of the backup mail folder is performed in accordance with the input security certificate information.

As shown in Figure 4, when the user initiates a mail backup, the page of the terminal prompts the user to upload the same. The security certificate bound to the email account, and prompted to enter the security certificate password. After the verification is passed, the security certificate information is written into the backup mail folder to start the backup.

When the backup is completed, when the user opens the backup mail folder in the storage device (such as SD card), the user is prompted to enter the security certificate password. After the risk certificate is passed, the folder is opened.

When the user selects the advanced security policy, that is, when the password is required to be input, during the process of reading the specific email, when the screen is not clicked within the specified time, the system automatically enters the mail lock screen state and saves the current state of the email. The next time the user clicks on the screen, the unlocking mechanism is triggered, and the nickname corresponding to the contact of the email is entered as the opening password. The nickname is that each user has been set up before the backup, and has been copied to each backup mail text folder during backup, as a user-defined key field. In the lock screen state, the user enters the correct nickname (open password) to unlock and returns to the reading interface of the mail. If the first input is unsuccessful, multiple input is allowed, and the unlocking device presets a fixed maximum number of inputs (ie, The threshold is restarted, which is customized by the user. If the input exceeds this number, the terminal automatically returns to the basic security policy state, and the user is required to input the security certificate information to log in again. This approach prevents privacy leakage and provides an entry for the user to forget the opening password of the current contact and not to enter the email.

The present invention also provides a system for browsing historical mails offline. As shown in FIG. 2, the present invention includes a mail server 10, a processor 20, and a storage device 30, wherein the processor 20 includes a local storage module 201.

Mail server 10, for receiving mail from the network;

The processor 20 is configured to obtain a mail from the mail server 10 and store it in the local storage module 201. The backup mail folder is set up in the storage device 30, and the mail in the local storage module 201 is backed up to the backup mail file. In the folder;

a local storage module 201, configured to store mail locally;

The storage device 30 is configured to store the backed up mail. The storage device 30 can be a storage device that can be connected to a mobile phone or a PC, such as an SD card or a mobile hard disk.

Three detailed embodiments will be enumerated below to explain the detailed flow of the method of browsing history mail provided by the present invention.

Example 1

As shown in FIG. 5, it is a flowchart of a method for offline browsing history mail provided by Embodiment 1 of the present invention, where the method includes the following steps;

Step 201: The user starts a full backup and an advanced backup for the first time. A full backup is a default backup. All mail on the local or server. Advanced backup refers to the security policy adopted during backup.

Step 202: The advanced backup needs to collect the information required by the normal backup and secondary security policies at the same time. Ordinary backups need to upload the certificate associated with the account, which is used to open the identity verification of the historical mail folder. The secondary security policy needs to set the sender's nickname in advance. In the backup, if the advanced backup is selected, the backup will be performed. When the sender's address is associated with the nickname, the operation when the user opens an advanced email through the SD card is the same as the basic backup, but if you are reading the email interface, after 1 minute or after setting In the default time period, if the user has not clicked on the screen, the user needs to lock the screen. The unlocking password can be the corresponding nickname of the sender, so that the user does not need to remember the password and ensure the security of the email. Sex.

Step 203: The system starts to read the information of each email to prepare for the following backup. The information read includes the header, body, etc., and the sender's address is stored separately.

Step 204: After the preparation is ready, start the backup.

Step 205: Determine whether the backup is completed. If not, proceed to step 204.

Step 206: After the backup is completed, you can open the SD card and view the history email.

Step 207: Because it is offline, the system opens the historical mail in the form of a document. When the folder is opened, the system detects that a certificate exists and prompts the user for authentication.

Step 208: After the verification is passed, the historical mail folder can be successfully opened. Step 209: The verification fails and the history mail folder cannot be opened.

Step 210: Due to the secure backup used during backup, a secondary security policy is required. After reading the sender A's email interface, the user has not clicked on the screen, the mobile phone enters the lock screen state, and the user inputs the nickname of the previously set A, and the user is successfully unlocked, and the mail of A can be normally viewed.

Example 2

As shown in FIG. 6, it is a flowchart of a method for offline browsing history mail provided by Embodiment 2 of the present invention, which describes a method for completely backing up a mail and partially browsing mail after offline mailing, which includes the following steps;

Step 301: The user has previously enabled mail backup.

Step 302: After receiving the new mail, the user starts the full and normal backup again.

Step 303: Collect information required for normal backup, and the user uploads a certificate associated with the account. Step 304: The system starts to read the information of each mail, including the mail header, mail body, etc., and stores the sender address separately.

Step 305: Since the mail has been backed up before, the user may complete the backup again without deleting, so it is necessary to query whether there is a duplicate record. If yes, go to step 306; otherwise, go to step 307.

Step 306: There are duplicate records, skip duplicate records, and only back up new mail.

Step 307: Back up the mail.

Step 308: Determine whether the backup is completed. If yes, go to step 309; otherwise, return to step 307.

Step 309: After the backup is completed, you can open the SD card and view the historical mail.

Step 310: Because it is offline, the system opens the historical mail in the form of a document. When the folder is opened, the system detects that a certificate exists and prompts the user for authentication.

Step 311: The verification fails and the history mail folder cannot be opened.

Step 312: The risk certificate is passed, and the historical mail folder can be successfully opened. Example 3

As shown in FIG. 7, the method flow for offline browsing history mail provided by Embodiment 3 of the present invention includes:

Step 401: First, the normal backup mail is performed by the system with the mail client.

Step 402: Move the SD card to another terminal to open the historical mail folder.

Step 403: The system first detects whether the client login is supported, and the network is good.

Step 404: If the client is supported to log in, and the network is good, the user is prompted to log in with the client or directly using the document form. If the user has deleted the historical mail on the server after backing up the mail, the user will select the document mode. If the user does not delete the history mail, the user can also open it by using the client.

Step 405: If it is detected that the terminal does not have the condition for the client to log in, the document is opened by default, so the user is prompted to perform identity verification.

Step 406: The user selects the client mode to open, that is, enters the email login interface. Step 407: Passed the authentication, the historical mail can be opened normally.

Step 408: Authentication failed, unable to open historical mail.
