[0069] To better understand the above technical solutions, exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments described herein. Instead, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0070] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0071] Reference Figure 2 The first embodiment of the present invention provides a flowchart of an application push method. In this embodiment, the application push method includes the following steps:

[0072] Step S10, obtaining the application package name of the current application, and if the application package name exists in the application store, taking a screenshot of the current display interface to generate screenshot data;

[0073] In this embodiment, the application push method is applied to an application push system. The application push system belongs to a smart home. A smart home uses a residential platform and integrates home-related facilities using integrated wiring technology, network communication technology, security technology, automatic control technology, audio and video technology, etc., to build an efficient management system for residential facilities and family schedules. With the improvement of living standards, users frequently install various applications on smart devices such as smartphones and tablets. Users' preferences for application selection are constantly changing. If the characteristics of applications installed by users on smart devices can be more quickly understood, more relevant applications can be quickly recommended to users. However, a key technical problem lies in how to enable the cloud to quickly identify the type and name of applications in smart devices. Therefore, the present invention proposes a method for identifying the name and type of applications in smart devices and generating a fingerprint identification code based on the application type and name. This method enables the application push system to push other applications of the same type as the application currently being viewed by the user when the user is using the application, effectively improving the accuracy of application push. It is understood that the application push system can be set up in the smart device to generate fingerprint identification codes and push applications in a timely manner.

[0074] Furthermore, the system identifies the current application running in the smart device. Specifically, the system calls the application thread running in the foreground, obtains the application information of the current application through the application thread, and identifies the application package name in the application information, wherein the package name (Package name) is the unique identifier of the application, that is, the package name is unique, one package name represents one application, and two applications are not allowed to use the same package name. Furthermore, the system compares the application package name of the current application with all standard application package names in the application store to determine whether the application package name exists in the application store. After determining that the application package name exists in the application store, it determines that the current application exists in the application store and takes a screenshot of the current display interface. Furthermore, if it is determined that the current application exists in the application store, the system obtains the screenshot parameters pre-set by the user or the system according to the screenshot requirements, and takes a screenshot of the current display interface of the current application in the smart terminal according to the obtained screenshot parameters to obtain initial screenshot data representing the screenshot image. Furthermore, the system compares the initial format of the initial screenshot data with a preset format. If the initial format is the same as the preset format, the system performs format conversion on the initial screenshot data to generate screenshot data representing the final screenshot.

[0075] Step S30: Generate a fingerprint identification code based on the screenshot data, and send the fingerprint identification code to the cloud, so that the cloud can obtain the corresponding target application according to the fingerprint identification code and push it to the current display interface.

[0076] Furthermore, after generating the screenshot data, the system inputs the image information in the screenshot data into a random encryption program, processes the image information through the random encryption program, and obtains a fingerprint identification code based on the processed image hash value, wherein the random encryption program is used to generate a fingerprint identification code based on the image information in the screenshot data. Furthermore, the system sends the fingerprint identification code to the cloud, so that the cloud can obtain the type and name of the current application based on the fingerprint identification code, search for a target application with the same name and type as the current application from the application store or application database, and push the application information of the target application to the current display interface. The user can click or touch the application information to jump to the application introduction page of the target application. If the user is interested in the target application, the target application can be downloaded and used.

[0077] Furthermore, the step of sending the fingerprint identification code to the cloud includes:

[0078] Step S34, transcoding the fingerprint identification code to obtain a transcoded fingerprint identification code;

[0079] In step S35 , the transcoded fingerprint identification code is sent to the cloud via a preset transmission channel.

[0080] Furthermore, in order to smoothly send the generated fingerprint identification code to the cloud without being maliciously intercepted by them, the system also needs to transcode the generated fingerprint identification code. Specifically, the system interacts with the cloud and agrees on encoding and decoding rules with the cloud. After completing the agreement on the encoding and decoding rules, the generated fingerprint identification code is transcoded according to the encoding and decoding rules to obtain the transcoded fingerprint identification code. Furthermore, the system sends the transcoded fingerprint identification code to the cloud through a preset transmission channel, so that the cloud can decode the transcoded fingerprint identification code according to the agreed encoding and decoding rules, and parse the decoded fingerprint identification code to obtain the corresponding current application type and name, and search the application store or application database for the target application with the same name and type as the current application, and push the application information of the target application to the current display interface. The user can click or touch the application information to jump to the application introduction page of the target application. If the user is interested in the target application, the target application can be downloaded and used.

[0081] This embodiment provides an application push method, apparatus, device, and computer-readable storage medium, which obtains the application package name of the current application. If the application package name exists in the application store, the current display interface is captured to generate screenshot data; a fingerprint identification code is generated based on the screenshot data, and the fingerprint identification code is sent to the cloud, so that the cloud can obtain the corresponding target application based on the fingerprint identification code and push it to the current display interface. After determining that the current application is an application in the application store based on the application package name of the current application, the present invention captures the current display interface, generates a fingerprint identification code based on the screenshot data generated by the screenshot, and sends it to the cloud, so that the cloud can accurately search for application information of the same type based on the fingerprint identification code and push it to the display interface of the current application, effectively improving the accuracy of application push.

[0082] Furthermore, based on the first embodiment of the application push method of the present invention, a second embodiment of the application push method of the present invention is proposed. In the second embodiment, the step of generating a fingerprint identification code based on the screenshot data includes:

[0083] Step S31, inputting the screenshot data into a random encryption program;

[0084] Step S32, processing the screenshot data according to the perceptual hash algorithm of the random encryption program to calculate an image hash value;

[0085] Step S33: Determine the image hash value as the fingerprint identification code of the screenshot data.

[0086] Furthermore, a fingerprint unique identification module is provided in the system, and the fingerprint unique identification module is used to generate the screenshot data into a fingerprint identification code through an internally set random encryption program, and a perceptual hash algorithm is provided in the random encryption program. Furthermore, the system extracts image information such as the length information, width information, width and height of the image frame in the screenshot data, and inputs the image information and the generated screenshot data into the random encryption program of the fingerprint unique identification module. The screenshot data is processed through the perceptual hash algorithm of the random encryption program and the image information to calculate the image hash value. Furthermore, after the image hash value is calculated through the random encryption program of the fingerprint unique identification module, the system determines the image hash value as the fingerprint identification code generated by the screenshot data captured from the current application. The fingerprint identification code can be used to uniquely identify the current application, and the current application type and name can be obtained through the fingerprint identification code, and the target application with the same or similar type and name as the current application can be searched.

[0087] Furthermore, the step of processing the screenshot data according to the perceptual hash algorithm of the random encryption program to calculate the image hash value includes:

[0088] Step S321, scaling the screenshot data according to the perceptual hash algorithm of the random encryption program, and performing grayscale processing on the scaled screenshot data to obtain grayscale image information;

[0089] Step S322, performing discrete cosine transform on the grayscale image information, and determining target matrix data from the matrix data after the cosine transform;

[0090] Step S323: Calculate the image hash value according to the target matrix data.

[0091] Furthermore, the system calls the random encryption program in the fingerprint unique identification module and scales the screenshot data using the perceptual hash algorithm set in the random encryption program, combined with the input image information. Specifically, because it is necessary to filter out the high-frequency and detailed content of the screenshot image while retaining the structural brightness and darkness, the system scales the screenshot data based on image information such as the length and width of the image frame, as well as the width and height of the image. In this embodiment, the screenshot data can be reduced to an 8x8 size, resulting in 64 pixels, to reduce image deviations caused by different sizes and proportions. Furthermore, to facilitate further processing of the scaled screenshot data, the system also needs to simplify the colors of the scaled screenshot data. Specifically, the scaled screenshot data is grayscaled using a binarization algorithm to obtain binary grayscale image information. For example, the scaled screenshot data is converted to 64 levels of grayscale, meaning that all pixels in the screenshot data have a total of 64 colors. Furthermore, the system performs a discrete cosine transform on the grayscale image information. The discrete cosine transform decomposes the image into frequency clusters and trapezoidal shapes. Although JPEG uses an 8*8 discrete cosine transform, a 32*32 discrete cosine transform is used in this embodiment to achieve better results. Furthermore, after completing the discrete cosine transform to obtain a 32*32 matrix, since the 8*8 matrix in the upper left corner of the matrix presents the lowest frequency in the grayscale image information, the 8*8 matrix in the upper left corner of the matrix is ​​determined as the target matrix data. Furthermore, the system calculates the hash value of the grayscale image based on the target matrix data.

[0092] Furthermore, the step of calculating the image hash value according to the target matrix data includes:

[0093] Step S3231, performing average calculation on the target matrix data to obtain matrix mean data;

[0094] Step S3232, performing a hash operation on the matrix mean data to obtain hash matrix data;

[0095] Step S3233: convert the hash matrix data into hash image data, and combine the hash image data to obtain an image hash value.

[0096] Furthermore, the system first calculates the average value of the target matrix data. Specifically, it calculates the average value of the 64 values ​​in the target matrix data to obtain matrix mean data. Furthermore, the system performs a hash operation based on the matrix mean data representing the 8*8 discrete cosine transform matrix, assigning hash values ​​of 0 or 1 to each of the 64 average values. Average values ​​greater than or equal to the discrete cosine transform mean are set to "1," and average values ​​less than the discrete cosine transform mean are set to "0." After completing the hash operation, hash matrix data is formed. It can be understood that as long as the overall structure of the screenshot image remains unchanged, the resulting value of the hash operation remains unchanged. Therefore, this embodiment can avoid the effects of gamma correction or color histogram adjustments. Furthermore, to facilitate cloud-based recognition and parsing, the system also converts the character-based hash matrix data into long integer hash image data. Furthermore, the system combines the hash images in a specific order to obtain an image hash value representing the fingerprint identification code. The order is not limited in this embodiment.

[0097] This embodiment processes the screenshot data through the perceptual hash algorithm in the random encryption program, generates an image hash value and determines the image hash value as the fingerprint identification code of the screenshot data, so as to facilitate sending the fingerprint identification code to the cloud, so that the cloud can accurately search for application information of the same type based on the fingerprint identification code and push it to the display interface of the current application, effectively improving the accuracy of application push.

[0098] Furthermore, based on the first embodiment of the application push method of the present invention, a third embodiment of the application push method of the present invention is proposed. In the third embodiment, if the application package name exists in the application store, taking a screenshot of the current display interface and generating the screenshot data include:

[0099] Step S11, obtaining the standard application package names of all applications in the application store, and if any of the standard application package names matches the application package name, determining that the application package name exists in the application store.

[0100] Furthermore, the system calls the background service to obtain the standard application package names of all applications from the application store package name library, compares the application package name of the current application with each standard application package name, and determines whether any standard application package name matches the application package name, wherein the application store contains multiple applications that meet the installation standards, and each application has a unique corresponding standard application package name. Specifically, the system uses a character matching algorithm to compare the character information in the application package name with the character information of each standard application package name for consistency. The character matching algorithm includes a variety of algorithms such as the BF (Brute Force) algorithm, the RK (Rabin Karp) algorithm, the BM (Boyer Moore) algorithm, and the Sunday algorithm. The specific algorithm of the character matching algorithm is not limited in this embodiment. Furthermore, if the character information in the application package name is compared with the character information of each standard application package name for consistency through a character matching algorithm, and it is determined that the payment information of any standard application package name in each standard application package name completely matches the payment information of the application package name, the system determines that the application package name of the current application exists in the application store, indicating that the current application can be found in the application store and is a legally installed application. Generating a fingerprint identification code based on the current application and pushing the corresponding application will not cause adverse effects.

[0101] On the contrary, if the character information in the application package name is compared with the character information of each standard application package name for consistency through a character matching algorithm, and it is determined that the payment information of each standard application package name does not match the payment information of the application package name, the system determines that the current application does not exist in the application store and is suspected of being illegally installed or the information has been tampered with. Generating a fingerprint identification code based on the current application and pushing the corresponding application may cause adverse effects.

[0102] This embodiment compares the application package name of the current application with the standard application package names to determine whether any of the standard application package names matches the application package name. This can determine whether the current application is legally installed to ensure the security of the system and avoid pushing information with adverse effects to users.

[0103] Furthermore, based on the first embodiment of the application push method of the present invention, a fourth embodiment of the application push method of the present invention is proposed. In the fourth embodiment, if the application package name exists in the application store, taking a screenshot of the current display interface and generating screenshot data includes:

[0104] Step S21, obtaining screenshot parameters, taking a screenshot of the current display interface according to the screenshot parameters, and generating initial screenshot data;

[0105] Step S22 , identifying the initial format of the initial screenshot data, and if the initial format is the preset format, performing format conversion on the initial screenshot data to generate screenshot data.

[0106] Understandably, since the display screen sizes of different smart devices, such as smartphones and tablets, vary, the screenshot parameters used when taking screenshots of different smart devices are also different. Furthermore, if it is determined that the application package name exists in the app store, the system obtains the display information of the current smart device and uses the display information as the screenshot parameters of the current smart device, where the display information includes at least resolution information and the length and width of the display screen. Furthermore, the system takes a screenshot of the current display interface representing the application page currently being used by the user according to the screenshot parameters, and after completing the screenshot, generates initial screenshot data representing the screenshot image. Furthermore, the system reads the initial format of the initial screenshot data, identifies the initial format, and compares the initial format with a preset format to determine whether the initial format is the same as the preset format. In this embodiment, the preset format is the YUV format. YUV is a color encoding system primarily used in video and graphics processing pipelines. Compared to the RGB color space, the YUV format facilitates data encoding and transmission, reduces bandwidth usage, and reduces the probability of information errors. Furthermore, if the initial format is determined to be the same as the preset format after comparison, it means that the initial format of the initial screenshot data meets the preset format. Since the initial screenshot data in the preset format cannot be recognized by the random encryption program, that is, the preset format does not meet the conditions for generating a fingerprint identification code from the initial screenshot data, it is necessary to perform format conversion on the initial screenshot data to convert the initial screenshot data into data in the target format. Furthermore, the system performs format conversion on the initial screenshot data. Specifically, it identifies the target format, obtains the conversion relationship between the preset format and the target format, and converts the initial screenshot data according to the conversion relationship between the preset format and the target format to generate screenshot data representing data that can be recognized by the random encryption program. In this embodiment, the preset format is the YUV format, and the target format is the JPEG (Joint Photographic Experts Group) format.

[0107] In this embodiment, when the current application exists in the application store, a screenshot of the current display interface is taken according to the screenshot data, and when the initial format of the initial screenshot data is a preset format, the screenshot data is generated. Since the initial format is the preset format, it is convenient to encode and transmit the data, reduce bandwidth usage and reduce the probability of information errors, and convert the initial screenshot data into screenshot data of the target format, so as to facilitate the generation of a fingerprint identification code based on the screenshot data.

[0108] Furthermore, the present application also provides an application push device.

[0109] Reference Figure 3 , Figure 3 This is a functional module diagram of the first embodiment of the push device used in this application.

[0110] The application push device includes:

[0111] The screenshot module 10 is used to obtain the application package name of the current application, and if the application package name exists in the application store, take a screenshot of the current display interface to generate screenshot data;

[0114] The acquisition unit is used to acquire the standard application package names of all applications in the application store, and if any standard application package name among the standard application package names matches the application package name, it is determined that the application package name exists in the application store.
