Description

Detection method of application notification message and electronic equipment

Technical Field

The present application relates to the field of terminal technologies, and in particular, to a method for detecting an application notification message and an electronic device.

Background

With the continuous development of intelligent electronic devices (such as mobile phones) and the increase of the number of applications, the number of applications installed in the electronic devices is increasing. Various application programs often push notification messages to users in order to achieve different business purposes; wherein the content of the notification message pushed to the user by different application programs is different. For example, a news class application may push real-time news and hotspots to users; the investment financing class application may push an investment financing message to the user, etc.

Some malicious applications, however, present problems of revealing user privacy and affecting user property security with respect to the content of notification messages pushed to users.

Disclosure of Invention

The embodiment of the application provides a detection method of an application notification message and electronic equipment, which can remind a user of risks and protect privacy and property safety of the user.

The embodiment of the application adopts the following technical scheme:

In a first aspect, a method for detecting an application notification message is provided, and the method is applied to an electronic device, in which a first application is installed, and includes: the electronic equipment receives a first notification message of a first application and acquires attribute information of the first notification message; wherein the attribute information of the first notification message includes a notification title and notification content of the first notification message; the electronic equipment takes attribute information of the first notification message as input, and operates a text classification model to obtain a text classification prediction result; the text classification prediction result is used for indicating whether the first notification message is a target notification message, wherein the target notification message is a notification message with risk of revealing user privacy or losing user property; if the text classification prediction result indicates that the first notification message is a target notification message, the electronic equipment displays a second notification message; the second notification message comprises a notification title, notification content and risk prompt information created by the electronic device based on the first notification message, wherein the risk prompt information is used for prompting a user that the first notification message has risks.

Based on the first aspect, after the electronic equipment receives a first notification message of a first application, the electronic equipment acquires attribute information of the first notification message, and runs a text classification model by taking the attribute information of the first notification message as input so as to obtain a text classification prediction result; if the text classification prediction result indicates that the first notification message is the target notification message, the electronic equipment displays a second notification message, wherein the second notification message not only comprises a notification title and notification content of the first notification message, but also comprises risk prompt information created by the electronic equipment based on the first notification message.

In one implementation manner of the first aspect, the method further includes: the electronic equipment receives a first operation of a user on the second notification message; the first operation is used for triggering the electronic equipment to display a detail page of the notification content corresponding to the first notification message; the electronic device does not respond to the first operation; or the electronic device displays a first interface in response to the first operation, the first interface not including a detail page of notification content of the first notification message.

In this implementation, the electronic device may be configured to not respond to the user's operation on the second notification message; or the electronic device does not display a detail page of the notification content of the first notification message in response to the user's operation on the second notification message. Thus, the user cannot see the detail page of the notification content corresponding to the first notification message, and the problems of revealing the user privacy and property safety are avoided.

In one implementation manner of the first aspect, the method further includes: if the text classification prediction result indicates that the first notification message is the target notification message, the electronic device closes the message pushing service of the first application.

In this implementation, if the electronic device identifies that the first notification message is a target notification message, that is, the text classification prediction result indicates that the first notification message is a target notification message, the electronic device closes the message push service of the first application. Therefore, the first application can not push the notification message in the using process, and the problems of revealing the privacy and property safety of the user are fundamentally solved.

In an implementation manner of the first aspect, the electronic device stores a preset application list, where the preset application list includes application package names of applications whose user usage frequency is less than a preset frequency; the method further comprises the steps of: if the text classification prediction result indicates that the first notification message is a target notification message, the electronic equipment acquires an application package name of the first application; and if the application package name of the first application is in the preset list, the electronic equipment uninstalls the first application.

In this implementation manner, by matching the application package name of the first application with the preset list, if the application package name of the first application is in the preset list, the electronic device uninstalls the first application, that is, the electronic device uninstalls the application that is not commonly used by the user. Thus, the problems of revealing user privacy and property safety can be further avoided.

In an implementation manner of the first aspect, obtaining attribute information of the first notification message includes: if the first application is not the application downloaded by the electronic equipment from the application store, the electronic equipment acquires the attribute information of the first notification message.

If the potential safety hazard of the application is detected, the application is not put on shelf in the application store. That is, applications that can be put on shelf in the application store are not hidden by security, i.e., normal applications. In the subsequent use process, the target notification message is not pushed

In the implementation manner, by judging whether the first application is downloaded from the application store, if the first application is downloaded from the application store, the electronic device can normally display the first notification message pushed by the first application without executing the method of the application; if the first application is not downloaded from the application store, the electronic device executes the method of the application to identify whether the first notification message is a target notification message so as to reduce the power consumption of the device.

In an implementation manner of the first aspect, the electronic device stores a correspondence between the notification message and the risk prompt information; if the text classification prediction result indicates that the first notification message is a target notification message, the electronic device displays a second notification message, including: if the text classification prediction result indicates that the first notification message is a target notification message, the electronic equipment acquires attribute information of risk prompt information corresponding to the first notification message; the attribute information of the risk prompt information comprises a prompt box and prompt contents; the electronic device displays a second notification message based on the prompt box and the prompt content of the risk prompt message, and the notification title and the notification content of the first notification message.

In one implementation manner of the first aspect, the method further includes: the electronic equipment stores the first notification message and a text classification prediction result corresponding to the first notification message as a group of log files; if the number of the log files stored by the electronic equipment is larger than a preset number threshold, the electronic equipment sends a first notification message and a text classification prediction result corresponding to the first notification message to the server; the text classification prediction result corresponding to the first notification message is used for updating the text classification model; the electronic equipment receives the updated text classification model from the server; the updated text classification model is updated by the server through an over-the-air technology OTA.

The workflow of the software system and hardware system of the electronic device 100 is illustrated below in connection with the scenario of applying push notification messages.

Referring to fig. 5, a schematic diagram of the software architecture, hardware structure, and server interaction of the electronic device 100 is shown. The embodiment of the present application is described herein with reference to the interaction diagram shown in fig. 5, which describes a software architecture, a hardware structure, and a specific implementation flow of detection of the server collaboration completion application notification message of the electronic device 100. The software architecture includes a first application in an application layer, and a management class (hereinafter referred to as notification) and a system interface application (hereinafter referred to as system UI) of status bar notifications in an application framework layer. The hardware structure mainly includes a read-only memory (ROM). Wherein the ROM stores a text classification model. As shown in fig. 5, the process may include steps ① - ⑥.

Step ①: the first application pushes a first notification message to the notification. Step ②: the ROM loads the stored text classification model into a random access memory (random access memory, RAM) for notification to detect the first notification message. On the basis, after the notification receives the first notification message of the first application, the text classification model is operated to obtain a text classification prediction result.

The text classification prediction result is used for indicating whether the first notification message is a target notification message, wherein the target notification message is a notification message with risk of revealing user privacy or losing user property.

If the text classification prediction result indicates that the first notification message is the target notification message, step ③: the notification stores the first notification message and the text classification prediction result corresponding to the first notification message as a set of log files in the ROM. Step ④: the notification system UI displays a second notification message. The second notification message comprises a notification title, notification content and risk prompt information created by notification based on the first notification message, wherein the risk prompt information is used for prompting a user that the first notification message has risks.

Step ⑤: and uploading the saved log file to a server by the ROM, and updating the text classification model according to the log file by the server. Step ⑥: the server sends the updated text classification model to the ROM.

The method provided by the embodiment of the application is exemplified below.

It should be understood that, in the Android ^TM system, the notification message based on the status bar notification is a global system notification, which is mainly implemented through the management class (notification manager) of the status bar notification; wherein notification manager is responsible for sending or clearing notification messages.

By way of example, a notification message may be composed of the following attribute information:

Notification notification＝new NotificationCompat.Builder(context)

setContentTitle ("This is content title")// notification title

SetContentText ("This is content text")// notification content

.setWhen(System.currentTimeMillis())

SetSmallIcon (R.extensible. Small_icon)// Notification small icon

SetLargeIcon (bitmap factor. Decode resource (getResources ()), r.extensible_icon))/(notify big icon)

.build()；

By way of example, a notification message may consist of a notification title, notification content, a notification small icon, a notification large icon, a notification channel (channel), and so forth. Wherein the notification channel (channel) is used for managing the authority of all applications to push notification messages; when the application opens the right to push the notification message, the application can display the pushed notification message in the status bar.

Typically, the notification message displayed in the status bar by the application mainly includes a notification title and notification content, and as shown in fig. 1, the notification message includes a notification title: "today's top bar" and notification content: "Beijing: and (5) entering various public places to carry out negative proof time limit adjustment …. Therefore, in the embodiment of the application, the notification title and the notification content included in the notification message can be trained as a group of texts to obtain a text classification model.

In the present application, a notification message in which there is a risk of revealing user privacy or losing user property may be referred to as a malicious notification message (or a target notification message as shown in the above-described embodiments of the present application), and a notification message in which there is no risk of revealing user privacy or losing user property may be referred to as a normal notification message.

On the basis, the text (i.e. sample data) of the notification message is taken as the input of the model, the classification prediction result corresponding to the label is taken as the output of the model, and model training is carried out to obtain a text classification model. Wherein in the present application, the sample data (i.e., the text of the notification message) includes the text of the malicious notification message and the text of the normal notification message. That is, the application inputs the text of the malicious notification message and the text of the normal notification message into the machine model as training samples for training.

The tag is used for indicating the occurrence frequency of the target word in the text of the malicious notification message, and the classification prediction result corresponding to the tag comprises the malicious notification message (which can be expressed as lable 1) and the normal notification message (which can be expressed as lable 0). Wherein, the target words refer to some keywords which can characterize the notification message as malicious notification message, such as "pension", "financial management", "one's own profit", and the like.

It should be understood that the foregoing is merely illustrative of target words, and that different malicious notification messages may include other target words, which is not limited in this regard by embodiments of the present application.

Fig. 6 is a schematic flow chart of model training provided in an embodiment of the present application, and exemplary, as shown in fig. 6, a text of a malicious notification message and a text of a normal notification message are used as training samples and input into a machine model for training.

It should be noted that, in the model training process, the more the number of training samples, the more accurate the model training result, i.e. the more mature the text classification model obtained by training. Therefore, to ensure accuracy of the training results, the total number of training samples is about two tens of thousands or more, and the number of each sample is not less than ten thousands. That is, the text of the malicious notification message and the text of the normal notification message are not less than ten thousand pieces, respectively.

Further, since the notification message mainly includes a notification title (content title) and notification content (content text), the inputted training samples include the notification title and the notification content. Moreover, since the notification title and the notification content belong to different texts of the training sample, data preprocessing can be performed on the training sample for training.

Firstly, combining a notification title and notification content, then carrying out text vectorization processing on the combined notification title and notification content to obtain a numerical vector with a preset length, and finally inputting the numerical vector with the preset length into a machine model for training to obtain a final text classification model.

For example, the notification title and the notification content may be combined in the form of content title/content text, and then text vectorization processing is performed on the content title/content text to obtain a numeric vector with a preset length. The text vectorization process refers to converting the combined text characters of the notification title and the notification content into numeric characters with a fixed length (i.e., the preset length).

In some embodiments, if the length of the combined notification title and text characters of the notification content is less than the fixed length, the combined notification title and text characters of the notification content may be converted to numeric characters, which may be supplemented to the fixed length with space or punctuation marks. In other embodiments, if the length of the combined notification title and text characters of the notification content is greater than the fixed length, the combined notification title and text characters of the notification content may be truncated by the fixed length, and then the truncated text characters may be converted into digital characters.

And then taking the numerical vector with the preset length as the input of the machine model, taking the classification result corresponding to the label as the output of the machine model, and running the machine model for training to obtain the text classification model. For example, assuming that the training samples include twenty-four thousands, firstly, performing text vectorization processing on the twenty-four thousands of training samples, converting the twenty-four thousands of training samples into twenty-four thousands of numerical vectors with preset lengths, and then sequentially performing vector operation on the twenty-four thousands of numerical vectors with preset lengths, namely, calculating a vector quantity product of the numerical vectors with preset lengths.

It should be appreciated that the machine model includes multiple input layers (or convolution layers) and one output layer, and after the operation of the vector number product of the numerical vector with the preset length, the machine model finally outputs a calculated vector number product. The vector quantity product of the machine model output is as follows: the machine model is based on the actual values (i.e., actual classification results) obtained after training the training samples.

On this basis, the machine model adopts an activation function (such as sigmoid) to map the actual value obtained by training between [0,1] so as to facilitate the subsequent processing. Note that, in the present application, the classification result corresponding to the tag includes lable a1 and lable a 0. Wherein lable is used to indicate that the notification message is a malicious notification message, lable is used to indicate that the notification message is a normal notification message. Thus, the machine model maps the actual value trained to [0,1], then if the actual value is less than 0.5, it is denoted lable0, and if the actual value is greater than 0.5, it is denoted lable 1.

Further, starting from the actual value obtained by training the machine model, performing inverse regression training (namely adopting a back propagation algorithm) on the machine model, and enabling the obtained actual value (namely the actual classification result) to be consistent with the classification result corresponding to the label, thereby obtaining the trained text classification model.

In the present application, the machine model may be a convolutional neural network model (convolutional neural networks, CNN), a transducer model (transducer), a support vector machine model (support vector machines, SVM), or the like, which is not limited thereto.

In the application, the text classification model can be trained through the electronic equipment, and other devices with the model training function can also be used for training the text classification model; alternatively, the text classification model may be trained by a server, which is not limited by embodiments of the present application.

In summary, the text classification model can be trained through the steps, and the trained text classification model is adopted to detect the notification message pushed by the application, so as to identify whether the notification message pushed by the application is a malicious notification message. For example, the trained text classification model can be stored in a read-only memory ROM, and when the electronic equipment is started, the text classification model stored in the ROM is loaded into the RAM to operate. On this basis, when the application pushes a message, the electronic device may run a text classification model in RAM to identify whether the notification message pushed by the application is a malicious notification message.

Fig. 7 is a schematic diagram of a method for detecting an application notification message according to an embodiment of the present application, where, as shown in fig. 7, the method may be implemented by S201-S205.

S201, the electronic equipment receives a first notification message of a first application.

Illustratively, as shown in connection with FIG. 5, the first application pushes notification manager a first notification message; accordingly, notification manager receives the first notification message of the first application.

S202, the electronic equipment acquires attribute information of the first notification message.

Wherein the attribute information of the first notification message includes a notification title and notification content of the first notification message.

For example, in connection with the above embodiment, the attribute information of the first notification message may further include a notification small icon, a notification large icon, a notification channel (channel), and the like.

In some embodiments, as shown in connection with fig. 5, the first application carries the notification header and the notification content of the first notification message when pushing the first notification message to notification manager. Thus, after receiving the first notification message of the first application at notification manager, notification manager may obtain attribute information of the first notification message, that is, a notification title and notification content of the first notification message.

S203, the electronic equipment takes attribute information of the first notification message as input, and operates a text classification model to obtain a text classification prediction result; the text classification prediction result is used for indicating whether the first notification message is a target notification message or not.

Wherein the targeted notification message is a notification message that risks revealing user privacy or losing user property.

As shown in connection with fig. 5, after the first application pushes the first notification message to notification manager, the ROM loads the stored text classification model to notification manager. And then notification manager takes the attribute information of the first notification message as input, and operates the text classification model to obtain a text classification prediction result.

In some embodiments, the electronic device may pre-process the attribute information of the first notification message before entering the attribute information of the first notification message into the text classification model. For example, in combination with the above embodiment, the electronic device first combines attribute information (such as a notification header and notification content) of the first notification message, and then performs text vectorization processing on the combined notification header and notification content to obtain a numeric vector with a preset length.

Subsequently, the electronic equipment takes the numerical vector with the preset length as input, operates a text classification model, and performs vector quantity product calculation on the numerical vector with the preset length. If the vector quantity product is larger than the preset vector quantity product, the text classification prediction result indicates that the first notification message is a target notification message; if the vector quantity product is smaller than the preset vector quantity product, the text classification prediction result indicates that the first notification message is a normal notification message.

In the present application, the predetermined vector quantity product may be any value between [0,1] above, for example, 0.5. Thus, when the vector number product is greater than 0.5, it indicates that the first notification message is a target notification message (i.e., a malicious notification message); when the vector quantity product is smaller than 0.5, the first notification message is indicated to be a normal notification message.

S204, if the text classification prediction result indicates that the first notification message is a normal notification message, the electronic device displays the first notification message.

S205, if the text classification prediction result indicates that the first notification message is the target notification message, the electronic device displays the second notification message.

The second notification message comprises a notification title, notification content and risk prompt information created by the electronic device based on the first notification message, wherein the risk prompt information is used for prompting a user that the first notification message has risks.

For example, as shown in fig. 8 (1), if the text classification prediction result indicates that the first notification message is a normal notification message, the notification title and the notification content are included in the first notification message displayed by the electronic device. As shown in (2) of fig. 8, if the text classification prediction result indicates that the first notification message is the target notification message, the second notification message displayed by the electronic device includes the notification title and the notification content of the first notification message, and the risk notification information corresponding to the first notification message.

In some embodiments, the electronic device stores a correspondence between the notification message and the risk prompt message; on the basis, if the text classification result indicates that the first notification message is the target notification message, the electronic equipment acquires attribute information of risk prompt information corresponding to the first notification message. The attribute information of the risk prompt information comprises a prompt box and prompt contents.

And then, the electronic equipment creates risk prompt information based on the prompt box and prompt content of the risk prompt information. For example, in connection with the above embodiment and as shown in fig. 5, after the electronic device obtains the prompt box and the prompt content of the risk prompt message, notification manager recreates a function based on the prompt box and the prompt content of the risk prompt message, and writes the prompt box and the prompt content of the risk prompt message into the recreated function. In this way, the electronic device will display a notification message (i.e., a second notification message) that includes the risk reminder information.

In summary, in the present application, after the electronic device receives the first notification message of the first application, the electronic device obtains attribute information of the first notification message, and uses the attribute information of the first notification message as input to run the text classification model to obtain a text classification prediction result; if the text classification prediction result indicates that the first notification message is the target notification message, the electronic equipment displays a second notification message, wherein the second notification message not only comprises a notification title and notification content of the first notification message, but also comprises risk prompt information created by the electronic equipment based on the first notification message.

Typically, before an application store of an electronic device (such as a mobile phone) is put on shelf, the application is detected, such as virus searching and killing, trojan searching and killing, and the like. If the potential safety hazard of the application is detected, the application is not put on shelf in the application store. That is, applications that can be put on shelf in the application store are not hidden by security, i.e., normal applications. In the subsequent use process, the target notification message is not pushed.

Based on this, in the embodiment of the present application, as shown in fig. 9, after the first application pushes the first notification message, that is, after the electronic device receives the first notification message of the first application, the electronic device may determine whether the first application is downloaded from the application store. If the first application is not downloaded from the application store, the electronic device obtains attribute information of the first notification message so as to detect whether the first notification message is a target notification message. If the first application is downloaded from the application store, the electronic device displays a first notification message pushed by the first application.

In this way, by judging whether the first application is downloaded from the application store, if the first application is downloaded from the application store, the electronic device can normally display the first notification message pushed by the first application without executing the method of the application; if the first application is not downloaded from the application store, the electronic device executes the method of the application to identify whether the first notification message is a target notification message so as to reduce the power consumption of the device.

To further protect user privacy and property security, in some embodiments, the electronic device may be configured to not respond to user operation of the second notification message; or the electronic device does not display a detail page of the notification content of the first notification message in response to the user's operation on the second notification message. Thus, the user cannot see the detail page of the notification content corresponding to the first notification message, and the problems of revealing the user privacy and property safety are avoided.

Taking an electronic device as an example of a mobile phone, as shown in (1) in fig. 10, the mobile phone receives a first operation of a user on a second notification message; the first operation is used for triggering the mobile phone to display a detail page of the notification content corresponding to the first notification message. In some embodiments, the mobile phone does not respond to the first operation, that is, after the mobile phone receives the first operation of the user on the second notification message, the mobile phone does not jump to the detail page of the notification content corresponding to the first notification message.

Or as shown in fig. 10 (2), the mobile phone displays a first interface in response to the first operation. The first interface does not include a detail page of the notification content of the first notification message, i.e., the first interface is a blank page.

In combination with any of the foregoing embodiments, in some embodiments, if the electronic device identifies that the first notification message is a target notification message, that is, the text classification prediction result indicates that the first notification message is a target notification message, the electronic device closes a message push service of the first application. Therefore, the first application can not push the notification message in the using process, and the problems of revealing the privacy and property safety of the user are fundamentally solved.

For example, in combination with the above embodiment, the electronic device may close a notification channel (channel) of the first application, that is, the electronic device closes the authority of the first application to push the notification message. In this way, even if the first application pushes a notification message, the pushed notification message is not displayed in the status bar.

It should be noted that, in general, applications that are not commonly used by users are installed on the electronic device, and the applications have a high probability of pushing the target notification message. Based on this, in the embodiment of the present application, the electronic device may further store a preset application list, where the preset application list includes application package names of applications whose user usage frequency is less than the preset frequency. That is, the preset list includes application package names of applications that are not commonly used by the user.

On the basis, if the text classification prediction result indicates that the first notification message is the target notification message, the electronic equipment acquires the application package name of the first application, and matches the application package name of the first application with a preset list. And if the application package name of the first application is in the preset list, the electronic equipment uninstalls the first application.

In this embodiment, by matching the application package name of the first application with the preset list, if the application package name of the first application is in the preset list, the electronic device uninstalls the first application, that is, the electronic device uninstalls the application that is not commonly used by the user. Thus, the problems of revealing user privacy and property safety can be further avoided.

Correspondingly, in combination with any of the above embodiments, if the electronic device identifies that the first notification message is the target notification message, the electronic device stores the first notification message and the text classification prediction result corresponding to the first notification message as a set of log files. For example, the electronic device stores the log file in the ROM.

In some embodiments, if the number of log files stored by the electronic device is greater than a preset number threshold, the electronic device sends a first notification message and a text classification prediction result corresponding to the first notification message to the server. In other embodiments, the electronic device periodically sends a first notification message to the server, and a text classification prediction result corresponding to the first notification message. For example, the electronic device sends the first notification message to the server every 24 hours, or 48 hours, and the text classification prediction result corresponding to the first notification message.

The server receives a first notification message sent by the electronic device and a text classification prediction result corresponding to the first notification message, and trains and updates a text classification model based on the first notification message and the text classification prediction result corresponding to the first notification message. Subsequently, the server sends the updated text classification model to the electronic device, which is stored in the ROM.

In some embodiments, the server may update the text classification model through over-the-air technology (OTA), that is, the server updates the text classification model simultaneously when updating the system of the electronic device, without separately updating the text classification model, thereby improving the resource utilization. It should be noted that the server may update the text classification model in other ways, which are not listed here.

The above description is given by taking the example of updating the text classification model by the server, and of course, the electronic device may also update the text classification model autonomously. For example, after the electronic device saves the first notification message and the text classification prediction result corresponding to the first notification message as a set of log files, the text classification model may be updated when the electronic device is powered on (e.g., each time the electronic device is powered on).
