Fig. 1 is a flow chart showing a method for previewing a message according to an exemplary embodiment. The method for previewing a message is applied to a terminal. As shown in Fig. 1 , the method for previewing a message includes the following steps.

In step 101, sensitive information in a message to be previewed is identified.

In step 102, the sensitive information in the message is replaced with fuzzy information to obtain preview information. The fuzzy information is information obtained by fuzzing the sensitive information.

In step 103, the preview information is displayed.

To sum up, the message preview method provided by this disclosure obtains the preview information by identifying sensitive information in the message to be previewed; replacing the sensitive information in the message with fuzzy information; and displays the preview information. Sensitive information is obtained after fuzzing, and only the sensitive information in the message is replaced with fuzzy information without changing other content in the message. In this way, the leakage of sensitive information in the message can be prevented and the security of message preview can be improved. ; In addition, the user can quickly determine the content of the message according to other content in the message.

Fig. 2 is a flow chart of a method for previewing a message according to another exemplary embodiment. The method for previewing a message is applied to a terminal. As shown in Fig. 2 , the method for previewing a message includes the following steps.

In step 201, sensitive information in a message to be previewed is identified.

The message may be an instant messaging message, such as a short message, an email, a Weibo message, a Michat message, a WeChat message, etc., which is not limited in this embodiment. Due to the strong real-time nature of instant messaging messages, users can set the preview function for such messages, so that when the terminal receives such messages, it can preview such messages so that users can view such messages in time .

Sensitive information refers to information that involves user privacy. For example, sensitive information includes the user's bank card balance, salary amount, password, verification code, and so on.

When the terminal receives a message, it needs to determine whether the message contains sensitive information; when the message contains sensitive information, identify the sensitive information in it; when the message does not contain sensitive information, it does not process the message and directly previews the message . This embodiment provides two identification methods for sensitive information in the message, and the two identification methods will be introduced respectively below.

In the first identification method, the sensitive information in the message to be previewed is identified, including: obtaining the sender account of the message and the message content of the message; searching for a match with the sender account and message content in the preset message template library message template; identify sensitive information in the message based on the found message template.

A message template library is pre-stored in the terminal, and the message template library can be downloaded from the server. The message template library includes message templates, and each message template is a template obtained after feature extraction is performed on a message including sensitive information. For example, if the sender account of a banking financial institution starts with 955, and the sensitive information includes credit limit xx, transfer-in amount xx, balance xx, etc., the terminal will send at least one of the credit line xx, transfer-in amount xx, and balance xx Type and the sender account number starting with 955 are set as a message template. For another example, if the sender account of the service organization starts with 1065, and the sensitive information includes verification code xx, dynamic password xx, etc., the terminal will send at least one of the verification code xx, dynamic password xx and The sender account is set as a message template.

When the terminal receives a message, it searches the message template library for a message template that matches both the sender's account number and message content; when the message template is found, it determines that the message contains sensitive information, and identifies the sensitive information in the message according to the message template. information; when the message template is not found, it is determined that the message does not include sensitive information.

When the position of the sensitive information in the message template is fixed, the terminal can determine the position of the sensitive information in the message template, and then determine the content at this position in the message as sensitive information; or, the terminal can determine the position of the sensitive information from the message template Sensitive keywords are searched for the sensitive keywords in the message, and the contents corresponding to the sensitive keywords are identified as sensitive information. For example, if the sensitive keyword is "verification code", and the content of the verification code is usually located after the three keywords of "verification code", then the character string that is located after "verification code" and includes numbers and/or letters can be identified for sensitive information.

When the message template library is not preset in the terminal, the terminal can first determine whether the message includes sensitive information according to the account number of the sender, and then identify the sensitive information in the message according to the keyword. In this way, in the second identification method, the method also includes: obtaining the account number of the sender of the message; detecting whether the account number of the sender belongs to a sensitive account, and the sensitive account is an account that sends a message including sensitive information; when the account number of the sender belongs to a sensitive account When using an account, it is determined that the message is a message that includes sensitive information.

For example, the sensitive account may be an account starting with 955, an account starting with 1065, etc., which is not limited in this embodiment.

At this time, identifying the sensitive information in the message to be previewed includes: obtaining the sensitive keyword corresponding to the sensitive account; finding the sensitive keyword in the message content of the message; identifying the content corresponding to the sensitive keyword as sensitive information.

Different sensitive accounts correspond to different sensitive keywords. For example, the sensitive keywords corresponding to sensitive accounts starting with 955 are credit limit, transfer amount, balance, etc.; the sensitive keywords corresponding to sensitive accounts starting with 1065 are verification code, dynamic password, etc.; therefore, the terminal can also obtain the sensitive keyword corresponding to the sensitive account, search for the sensitive keyword in the message, and identify the content corresponding to the sensitive keyword as sensitive information. For details, see the first description in the identification method.

In step 202, the fuzzy processing method corresponding to the sensitive information is determined, and the sensitive information is processed according to the fuzzy processing method to obtain fuzzy information.

The obfuscation processing method is used to process sensitive information, so that the fuzzy information obtained by the obfuscation processing cannot be recognized by the user. For example, the obfuscation method can be to replace each bit in the sensitive information with characters such as "*" and "#"; or, the obfuscation method can be to overlay a non-transparent layer on the sensitive information; or, to blur The processing method may be to mosaic the sensitive information, etc., which is not limited in this embodiment.

In this embodiment, the terminal can also set different obfuscation processing methods for different sensitive information, thereby extending the generation methods of the obfuscation information. For example, the fuzzy processing method corresponding to financial sensitive information such as credit limit and balance is to cover the non-transparent layer; the corresponding fuzzy processing method corresponding to verification sensitive information such as verification code and dynamic password is to replace each digit in the sensitive information into characters such as "*" and "#".

In step 203, the sensitive information in the message is replaced with fuzzy information to obtain preview information.

The terminal only replaces the sensitive information in the message with fuzzy information without changing other content in the message to obtain the preview information.

In step 204, the preview information is displayed on the lock screen interface of the terminal; or, the preview information is displayed on the notification bar of the terminal.

When the user is using the terminal, that is, when the terminal is in the lock screen state, the terminal displays the preview information on the lock screen interface. Please refer to the first display schematic diagram of preview information shown in FIG. 3 .

When the user is using the terminal, that is, when the terminal is in an unlocked state, the terminal displays preview information in a notification bar. Please refer to FIG. 4 for a second display diagram of preview information.

To sum up, the message preview method provided by this disclosure obtains the preview information by identifying sensitive information in the message to be previewed; replacing the sensitive information in the message with fuzzy information; and displays the preview information. Sensitive information is obtained after fuzzing, and only the sensitive information in the message is replaced with fuzzy information without changing other content in the message. In this way, the leakage of sensitive information in the message can be prevented and the security of message preview can be improved. ; In addition, the user can quickly determine the content of the message according to other content in the message.

Determine the fuzzy processing method corresponding to the sensitive information; process the sensitive information according to the fuzzy processing method to obtain fuzzy information, so that different sensitive information may correspond to different fuzzy processing methods, thereby expanding the generation method of fuzzy information.

In a possible implementation scenario, the user is using a terminal to register an account in an application. Usually, during the account registration process, the user needs to fill in the mobile phone number on the registration page of the application, and the application server sends a verification message to the mobile phone number. code, the user needs to fill in the verification code on the registration page and send it to the server. If the terminal displays the preview information in the notification bar at this time, the user cannot directly read the verification code from the preview information, but needs to leave the registration page first, then start the SMS application to view the verification code in the message, and then open the registration page , enter the verification code on the registration page, resulting in a long time-consuming registration process. Therefore, when the terminal receives the message, it also needs to determine whether to obfuscate the sensitive information. Please refer to the flow chart of the message preview method shown in FIG. 5 , before step 201 is performed, the terminal further performs steps 205 and 206 .

In step 205, when the message is received, it is detected whether the terminal is in a screen-locked state.

In step 206, when the terminal is in a screen-locked state, step 201 is triggered to be executed.

Among them, the technology for detecting whether the terminal is in the lock screen state is very mature, and will not be described here.

Since most users do not allow others to use their terminals, and users may need to read sensitive information in messages during the use of terminals, when receiving messages, check whether the terminal is in the lock screen state; when the terminal is in When the screen is locked, the step of identifying sensitive information in the message to be previewed is triggered, that is, the sensitive information is replaced with fuzzy information when the user is not using the terminal, which avoids the need for the user to manually view the sensitive information when the user needs to read it The original message makes the operation of obtaining sensitive information cumbersome, thereby improving the efficiency of obtaining sensitive information.

Some users have high requirements on terminal security, and these users do not want others to use their terminals. At this time, the users will enable an unlock password. When the user enables the unlock password, the terminal will ask the user to enter the unlock password when the user unlocks the screen of the terminal. When the unlock password entered by the user is consistent with the preset unlock password, the terminal will unlock the screen; If it is inconsistent with the preset unlock password, the terminal will continue to keep the screen locked to prevent the terminal from being used by others. Therefore, for a terminal with high security requirements, the terminal can perform obfuscation processing on sensitive information; for a terminal with low security requirements, the terminal can directly preview the received message. Please refer to the flow chart of the message preview method shown in FIG. 6 , before step 201 is performed, the terminal further performs steps 207 and 208 .

In step 207, it is detected whether the unlocking password is enabled on the terminal, and the unlocking password is used to verify the identity of the user.

Wherein, the terminal can read the unlocking configuration information set by the user, and determine whether the unlocking password is enabled according to the unlocking configuration information.

In step 208, when the unlocking password is enabled in the terminal, the execution of step 201 is triggered.

Optionally, the terminal may also detect whether the terminal is in the lock screen state when receiving the message; when the terminal is in the lock screen state, detect whether the terminal has enabled the unlock password; when the terminal has enabled the unlock password, trigger execution of step 201.

When the user does not want others to use his terminal, the unlocking password will be enabled. Therefore, it is detected whether the unlocking password is enabled on the terminal, and the unlocking password is used to verify the user's identity; The sensitive information in the step, so that it can be determined whether to replace the sensitive information with the fuzzy information according to the user's security requirements for the terminal.
