Referring to fig. 2, a first embodiment of the present invention provides a flowchart illustrating an application push method. In this embodiment, the application pushing method includes the following steps:
step S10, acquiring the name of the application package of the current application, and if the name of the application package exists in an application store, performing screen capture on the current display interface to generate screen capture data;
the application pushing method in the embodiment is applied to an application pushing system, the application pushing system belongs to an intelligent home, the intelligent home takes a home as a platform, and facilities related to the home are integrated by utilizing a comprehensive wiring technology, a network communication technology, a safety precaution technology, an automatic control technology, an audio and video technology and the like, so that an efficient management system for home facilities and home schedule affairs is constructed. With the improvement of living standard, a user often installs various applications on smart devices such as a smart phone and a tablet computer, the preference of the user for selecting the applications is updated all the time, and if the characteristics of the applications installed on the smart devices by the user can be known more quickly, more related applications can be recommended to the user quickly. However, a key technical problem is how to enable the cloud to quickly identify the type and name of an application in the smart device. Therefore, the invention provides a method for identifying the name and the type of the application in the intelligent device and generating the fingerprint identification code according to the application type and the name, so that the application pushing system can push other applications with the same type as the current application viewed by the user when the user uses the application, and the accuracy of application pushing is effectively improved. It is understood that the application push system may be disposed in the smart device, and the fingerprint identification code is generated and the application push is performed in real time.
Further, the system identifies the current application running in the smart device, specifically, the system invokes the application thread running in the foreground, obtains application information of the current application through the application thread, and identifies an application Package name in the application information, where the Package name is a 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. Further, the system compares the application package name of the current application with all standard application package names in the application store, determines whether the application package name exists in the application store, determines that the current application exists in the application store after determining that the application package name exists in the application store, and performs screen capture on the current display interface. Further, if the current application is determined to exist in the application store, the system acquires screen capture parameters preset by a user or the system according to screen capture requirements, and performs screen capture on the current display interface of the current application in the intelligent terminal according to the acquired screen capture parameters to obtain initial screen capture data representing a screen capture image. Further, the system compares the initial format of the initial screenshot data with a preset format, and if the initial format is the same as the preset format, format conversion is performed on the initial screenshot data to generate screenshot data representing the final screenshot.
And step S30, generating a fingerprint identification code based on the screen capturing data, and sending the fingerprint identification code to a cloud end, so that the cloud end can obtain a corresponding target application according to the fingerprint identification code and push the target application to a current display interface.
Further, after the screen capture data are generated, the system inputs the image information in the screen capture data into a random encryption program, processes the image information through the random encryption program, and obtains the fingerprint identification code according to the processed image hash value, wherein the random encryption program is used for generating the fingerprint identification code according to the image information of the screen capture data. Further, the system sends the fingerprint identification code to the cloud end, so that the cloud end can obtain the type and the name of the current application according to the fingerprint identification code, search a target application with the same name and type as the current application from an application store or an application database, push application information of the target application to a current display interface, enable a user to click or touch the application information and jump to an application profile page of the target application, and enable the target application to be downloaded and used if the user is interested in the target application.
Further, the step of sending the fingerprint identification code to a cloud comprises:
step S34, transcoding the fingerprint identification code to obtain a transcoded fingerprint identification code;
and step S35, sending the transcoded fingerprint identification code to the cloud through a preset transmission channel.
Further, in order to smoothly send the generated fingerprint identification code to the cloud without being maliciously intercepted by the cloud, the system also needs to transcode the generated fingerprint identification code. Specifically, the system interacts with the cloud end, jointly appoints an encoding and decoding rule with the cloud end, and after the appointment of the encoding and decoding rule is completed, the generated fingerprint identification code is transcoded through the encoding and decoding rule to obtain the transcoded fingerprint identification code. Further, the system sends the transcoded fingerprint identification code and a preset transmission channel to the cloud, so that the cloud decodes the transcoded fingerprint identification code according to an agreed encoding and decoding rule, analyzes the decoded fingerprint identification code to obtain a corresponding current application type and name, searches a target application with the same name and type as the current application from an application store or an application database, pushes application information of the target application to a current display interface, and allows a user to click or touch the application information to jump to an application profile page of the target application.
The embodiment provides an application pushing method, an application pushing device, application pushing equipment and a computer readable storage medium, wherein an application package name of a current application is obtained, and if the application package name exists in an application store, a current display interface is subjected to screen capture to generate screen capture data; and generating a fingerprint identification code based on the screen capture data, and sending the fingerprint identification code to a cloud end so that the cloud end can obtain a corresponding target application according to the fingerprint identification code and push the target application to a current display interface. According to the method and the device, after the current application is judged to be the application in the application store according to the application package name of the current application, the screen capture is carried out on the current display interface, the fingerprint identification code is generated according to the screen capture data generated by the screen capture and is sent to the cloud, so that the cloud can accurately search the same type of application information according to the fingerprint identification code and push the same to the display interface of the current application, and the accuracy of application pushing is effectively improved.
Further, a second embodiment of the application push method of the present invention is proposed based on the first embodiment of the application push method of the present invention, and in the second embodiment, the step of generating the fingerprint identification code based on the screen capture data includes:
step S31, inputting the screen capture data into a random encryption program;
step S32, processing the screen capture data according to the perceptual hash algorithm of the random encryption program, and calculating an image hash value;
and step S33, determining the image hash value as the fingerprint identification code of the screen capture data.
Furthermore, a fingerprint unique identification module is arranged in the system and used for generating the screen capture data into a fingerprint identification code through an internally arranged random encryption program, and a perceptual hash algorithm is arranged in the random encryption program. Further, the system extracts image information such as length information, width and height of the image frame in the screen capture data, inputs the image information and the generated screen capture data into a random encryption program of the fingerprint unique identification module, processes the screen capture data through a perception hash algorithm and the image information of the random encryption program, and calculates an image hash value. Further, after the image hash value is calculated through a random encryption program of the fingerprint unique identification module, the system determines the image hash value as a fingerprint identification code generated by intercepting screen capture data from the current application, the fingerprint identification code can be used for uniquely identifying the current application, the type and the name of the current application can be obtained through the fingerprint identification code, and a target application with the same type and the same name as or similar to the current application can be searched.
Further, the step of processing the screen capture data according to the perceptual hash algorithm of the random encryption program and calculating an image hash value includes:
step S321, scaling the size of the screen capture data according to the perceptual hash algorithm of the random encryption program, and performing gray processing on the screen capture data after scaling to obtain gray image information;
step S322, performing discrete cosine transform on the gray image information, and determining target matrix data from the matrix data after cosine transform;
step S323, calculating an image hash value according to the target matrix data.
Further, the system calls a random encryption program in the fingerprint unique identification module, and performs size scaling on the screenshot data by combining the input image information through a perceptual hash algorithm set in the random encryption program, specifically, since the high frequency and the detail content of the screenshot image need to be filtered and the structure brightness is kept, the system performs size scaling on the screenshot data by referring to the image information such as the length information, the width and the height of the image frame, and the like, in this embodiment, the screenshot data can be reduced to the size of 8x8 to obtain 64 pixels, so as to reduce the image deviation caused by different sizes and proportions. Further, in order to facilitate further processing of the scaled screen capture data, the system needs to perform color simplification on the scaled screen capture data, specifically, perform gray scale processing on the screen capture data after size scaling through a binarization algorithm to obtain binarized gray scale image information, for example, convert the screen capture data after size scaling into 64-level gray scale, that is, all pixel points in the screen capture data have 64 colors in total. Further, the system performs discrete cosine transform on the gray image information, wherein the discrete cosine transform is to aggregate the picture decomposition frequencies and have a ladder shape, although JPEG uses 8 × 8 discrete cosine transform, and 32 × 32 discrete cosine transform is used in the embodiment for better effect. Further, after the discrete cosine transform is completed to obtain 32 × 32 matrices, since 8 × 8 matrices in the upper left corner of the matrices represent the lowest frequencies in the grayscale image information, the 8 × 8 matrices in the upper left corner of the matrices are determined as target matrix data. Further, the system calculates the hash value of the gray level image according to the target matrix data.
Further, the step of calculating an image hash value according to the target matrix data includes:
step S3231, carrying out average value calculation on the target matrix data to obtain matrix average value data;
step S3232, performing hash operation on the matrix mean value data to obtain hash matrix data;
step S3233, convert the hash matrix data into hash image data, and combine the hash image data to obtain an image hash value.
Further, the system firstly performs average value calculation on the target matrix data, specifically, calculates the average value of 64 values in the target matrix data to obtain matrix average value data; further, the system performs hash operation according to matrix mean data representing 8 × 8 discrete cosine transform matrices, hash values of 0 or 1 are respectively set for 64 mean values, wherein the mean value greater than or equal to the discrete cosine transform mean value is set as '1', the mean value smaller than the discrete cosine transform mean value is set as '0', and hash matrix data are formed after the hash operation is completed. It can be understood that as long as the overall structure of the screen capture image remains unchanged, the result value of the hash operation is unchanged, and therefore the present embodiment can avoid the influence of gamma correction or color histogram adjustment. Further, in order to facilitate identification and analysis of the cloud, the system also needs to convert the hash matrix data in the character form into long and integer hash image data, and further, the system combines the hash images according to a certain order to obtain an image hash value representing the fingerprint identification code, where the order is not limited in this embodiment.
According to the embodiment, the screenshot data are processed through the perception hash algorithm in the random encryption program, the image hash value is generated and determined as the fingerprint identification code of the screenshot data, the fingerprint identification code is conveniently sent to the cloud, the cloud can accurately find the same type of application information according to the fingerprint identification code and pushes the same to the display interface of the current application, and the accuracy of application pushing is effectively improved.
Further, a third embodiment of the application push method according to the present invention is provided based on the first embodiment of the application push method according to the present invention, and in the third embodiment, if the application package name exists in the application store, the step of capturing the screen of the current display interface and generating the screen capture data includes:
step S11, acquiring the standard application package names of all the applications in the application store, and if any standard application package name in each standard application package name is matched with the application package name, judging that the application package name exists in the application store.
Further, the system calls background services, standard application package names of all applications are obtained from an application store package name library, the application package names of the current applications are compared with the standard application package names, whether any standard application package name is matched with the application package name exists in the standard application package names is determined, the application store contains a plurality of applications meeting the installation standard, and each application has a unique corresponding standard application package name. Specifically, the system uses a character matching algorithm to compare consistency of character information in the application packet name with character information of each standard application packet name, where the character matching algorithm includes multiple algorithms such as BF (Brute Force, storm) algorithm, rk (rabin karp) algorithm, bm (boyer moore) algorithm, and Sunday algorithm, and in this embodiment, specific algorithms of the character matching algorithm are not limited. Further, after consistency comparison is conducted on the character information in the application package names and the character information of each standard application package name through a character matching algorithm, it is determined that the payment information of any standard application package name in each standard application package name is completely matched with the payment information of the application package name, the system judges that the application package name of the current application exists in an application store, the representation that the current application can be found in the application store and belongs to legal installation application, and no adverse effect is caused by generating a fingerprint identification code according to the current application and pushing the corresponding application.
On the contrary, if the consistency comparison is carried out on the character information in the application package name and the character information of each standard application package name through a character matching algorithm, the fact that the payment information of each standard application package name in each standard application package name is not matched with the payment information of the application package name is determined, the system judges that the current application does not exist in an application store, the current application is suspected of illegal installation or information tampering, and the harmful effects are possibly caused by generating a fingerprint identification code according to the current application and pushing the corresponding application.
In this embodiment, by comparing the application package name of the current application with each standard application package name, it is determined whether any standard application package name is matched with the application package name in each standard application package name, and it can be determined whether the current application is legally installed, so as to ensure the security of the system and avoid pushing information with adverse effects to the user.
Further, a fourth embodiment of the application push method according to the present invention is provided based on the first embodiment of the application push method according to the present invention, and in the fourth embodiment, if the application package name exists in the application store, the step of capturing a screen of the current display interface and generating screen capture data includes:
step S21, acquiring screen capture parameters, and capturing a screen of the current display interface according to the screen capture parameters to generate initial screen capture data;
step S22, recognizing an initial format of the initial screen capture data, and if the initial format is the preset format, performing format conversion on the initial screen capture data to generate screen capture data.
It can be understood that, since the sizes of the display screens of different smart devices, such as a smart phone, a tablet computer, and the like, are different, the screen capture parameters adopted when the different smart devices are captured are also different. Further, if the name of the application package is determined to exist in the application store, the system acquires display information of the current intelligent device, and the display information is used as screen capture parameters of the current intelligent device, wherein the display information at least comprises resolution information and length and width information of a display screen. Further, the system captures a screen of a current display interface representing the current application page used by the user according to the screen capture parameters, and generates initial screen capture data representing the screen capture image after the screen capture is completed. Further, the system reads an initial format of the initial screen capture data, identifies the initial format, compares the initial format with a preset format, and determines whether the initial format is the same as the preset format, wherein the preset format is a YUV format in the embodiment, and YUV is a color coding system and is mainly used in a video and graphic processing pipeline.
