And then generating a data picture according to the processed application data and the selected picture format, and storing the data picture into a terminal album. The second application can go to the terminal album to obtain the data picture, and perform a series of analysis processing on the obtained data picture to obtain the application data. The first application stores the application data to be transmitted in a terminal album in a picture format so that a second application can obtain the application data from the terminal album, the transmission of the application data among different applications of the same terminal is realized by utilizing the storage function of the terminal album, the network is not required, and the occupation of resources of a server can be avoided.
Due to the limitation of the sandbox mechanism of the ios system, when application data transmission is performed between two application programs in the ios system, data transmission is mainly performed through a server, and more server resources are occupied and the operation is more complicated. The application data processing method of the embodiment of the application is applied to an ios system, the application data are stored in a terminal album in a picture format to realize transmission of the application data, resources of a server can be prevented from being occupied, and transmission of the application data can be realized without depending on a network. The ios system mentioned here is only one application environment of the embodiments of the present application and should not be understood as a specific limitation of the present application.
Please refer to fig. 2, which is a flowchart illustrating an application data processing method according to an embodiment of the present application. As shown in fig. 2, the application data processing method includes:
s201, the first application acquires application data to be transmitted.
The first application may be any application in the terminal, and the first application may obtain the application data to be transmitted after receiving the task instruction for transmitting the application data, where the application data may include but is not limited to: files, video, pictures, voice, background data during application running, and the like.
In one embodiment, the task instruction for transmitting the application data received by the first application may be a press instruction or a click instruction of the user on an application interface of the first application of the terminal, and the terminal generates the task instruction according to the press instruction or the click instruction. For example, when a user wants to send application data such as a file and a video in a first application to a second application, the user interface of the first application displaying the application data may be clicked or pressed, or the application data may be clicked or pressed, and after the terminal detects a click or press instruction of the user, a task instruction may be generated and sent to the first application to instruct the first application to acquire application data to be transmitted.
In another embodiment, the task instruction for transmitting the application data received by the first application may also be a voice instruction sent by the user to the terminal, and the terminal generates the task instruction according to the voice instruction. For example, when a user wants to send a profile file in a first application to a contact user a in a second application, the user may say "please send the profile file in the first application to the contact user a in the second application" to the terminal. After the terminal acquires the voice instruction sent by the user, a task instruction for transmitting the data file can be generated according to the voice instruction, and the task instruction is sent to the first application so as to instruct the first application to acquire the related application data of the data file.
In still another embodiment, the task instruction for transmitting the application data received by the first application may also be automatically generated by the terminal. In the running process of the first application and the second application, if the terminal detects that the application data is transmitted between the first application and the second application, the terminal can automatically generate a task instruction for transmitting the application data and send the task instruction to the first application so as to instruct the first application to acquire the relevant application data of the material file. For example, if the terminal detects keywords such as "file", "second application", etc. in the application interface of the first application, as shown in fig. 3, it may be considered that there may be a transfer of application data between the first application and the second application, and a task instruction is generated. This task instruction is then sent to the first application to instruct the first application to fetch the file "one xxx solution.
S202, the first application processes the application data to be transmitted to obtain the processed application data.
After the first application acquires the application data to be transmitted, a series of processing such as hash operation, data compression, data encryption and the like can be performed on the application data to be transmitted, so that the processed application data is obtained.
The data compression processing here means: on the premise of not losing useful application data, the application data is reduced or reorganized by adopting a compression algorithm, so that redundancy and storage space of the application data are reduced. Therefore, when the first application performs data compression processing on the application data to be transmitted, a compression algorithm may be used to perform compression processing on the application data to be transmitted, where the compression algorithm may include, but is not limited to: huffman (Huffman) algorithm, LZW (Lenpel-Ziv & Welch) compression algorithm, LZ (Lempel-Ziv) algorithm, LZR (LZ-Renau) algorithm, and the like. By compressing the application data to be transmitted, the memory of the terminal album occupied by the application data can be reduced, the data transmission efficiency can be improved, and the data transmission time can be saved.
The encryption process here may be an asymmetric encryption process or a symmetric encryption process. The application data to be transmitted is subjected to hash operation, data encryption and other processing, so that the safety of the application data in the transmission process can be improved.
S203, the first application selects a picture format and generates a data picture according to the processed application data and the picture format.
The picture format refers to a format in which a computer (terminal) stores pictures, and the picture format may include, but is not limited to: JEPG format, JPG format, PNG format, BMP format, PCX format, TIFF format, GIF format, TAG format, and the like.
Since each picture format has a corresponding image file structure, multiple data units may be included in the image file structure. Therefore, in an embodiment, a specific implementation manner of the first application selecting the picture format and generating the data picture according to the processed application data and the picture format may be: a first application selects an initial picture and acquires an image file structure of the initial picture, wherein the image file structure comprises at least one filled data unit; and the first application adopts the processed application data to replace the data in the at least one filled data unit to generate a data picture.
For example, the image file structure of the initial picture may be as shown in fig. 4a, and the image file structure includes a plurality of data units, each of which has associated data filled therein. Wherein, the data unit for filling the letter is the filled data unit. The processed application data is "65468 br93e6h6 ijk", the data in the filled data units are replaced by the processed application data, an image file structure as shown in fig. 4b can be generated, and a corresponding data picture can be obtained according to the image file structure as shown in fig. 4 b.
It should be noted that, in an embodiment, after the first application acquires the application data to be transmitted, the application data to be transmitted may not be processed, that is, step S202 is not executed. Therefore, in step S203, after the first application selects the picture format, the data picture can be directly generated according to the application data to be transmitted and the picture format.
S204, the first application stores the data picture into a terminal album so that a second application obtains the data picture from the terminal album and obtains the application data according to the data picture.
After the first application generates the data picture, the data picture may be saved in a terminal album, as shown in fig. 5. In one embodiment, since the data picture is generated according to the image file structure of the initial picture and the processed application data, there may be no actual image content in the data picture, and the user opens the data picture in the terminal album, and the content in the data picture will be displayed in the user interface of the terminal in a messy code form. After the second application acquires the data picture from the terminal album, the data picture can be analyzed to obtain application data. The parsing process herein may include, but is not limited to, a hash operation, a data decompression process, and a data decryption process.
In the embodiment of the application, after the first application acquires the application data to be transmitted, the application data to be transmitted may be processed to obtain processed application data. Then, the first application can select a picture format, generate a data picture according to the processed application data and the selected picture format, and store the data picture in a terminal album, so that a second application obtains the data picture from the terminal album, and obtains the application data according to the data picture. Therefore, the application data processing method provided by the embodiment of the application can store the application data to be transmitted in the terminal album in a picture format so that the second application can obtain the application data from the terminal album, thereby realizing the transmission of the application data, avoiding occupying resources of a server, and realizing the transmission of the application data without depending on a network.
Fig. 6 is a schematic flow chart of another application data processing method according to an embodiment of the present application. As shown in fig. 6, the application data processing method includes:
s601, the first application acquires application data to be transmitted.
In one embodiment, a user can perform authorization processing on the first application and the second application through the terminal in advance, so that the first application and the second application have access rights for accessing the terminal album.
S602, the first application adopts a one-way irreversible function to operate the application data to be transmitted, and first data are obtained.
The one-way non-reversible function may be a hash function that may pass an input of arbitrary length through a hash algorithm to a fixed length output. The hash function herein may include, but is not limited to: MD2(Message-Digest Algorithm 2) function, MD4(Message-Digest Algorithm 4) function, MD5(Message-Digest Algorithm 5) function, and the like. The first application calculates application data to be transmitted by adopting a hash function, so that tamper-resistant identification data can be obtained, and the tamper-resistant identification data is used as first data.
S603, the first application splices the first data and the application data to be transmitted to obtain second data.
In one embodiment, the first application may stitch the first data behind the application data to be transmitted to obtain the second data. In another embodiment, the first application may also splice the first data to the front of the application data to be transmitted to obtain the second data.
S604, the first application adopts a compression algorithm to compress the second data to obtain third data.
The first application may perform compression processing on the second data by using a data compression algorithm such as Huffman algorithm, LZW compression algorithm, LZ algorithm, and the like to obtain third data, which may specifically refer to step S202 in the foregoing embodiment, and details are not described here.
And S605, the first application adopts an encryption algorithm to encrypt the third data to obtain processed application data.
The first application may use a symmetric encryption algorithm or an asymmetric encryption algorithm to encrypt the third data, so as to obtain processed application data.
If the first application adopts a symmetric encryption algorithm to encrypt the third data, the public key and the private key used in the encryption process are consistent. Symmetric encryption algorithms herein may include, but are not limited to: des (data Encryption standard) algorithm, 3des (triple des) algorithm, aes (advanced Encryption standard) algorithm, and the like. In one embodiment, when the first application encrypts, the third data may be encrypted by using a public key or a private key agreed with the second application in advance. In one embodiment, since the application data may carry the data identifier, the first application may further encrypt the third data by using the data identifier of the application data.
In another embodiment, since each application has an application identifier, the first reference may use the application identifier of the first application or the second application as the encrypted public key and private key when the encryption algorithm is used for encryption. In an embodiment, if the number of the second applications is one, the first application may obtain an application identifier of the second application, and encrypt the third data by using the application identifier of the second application, so that the second application may directly decrypt the processed application data by using its own application identifier after obtaining the processed application data. In another embodiment, if the number of the second applications is multiple, the first application may encrypt the third data by using its own (first application) application identifier. After the second application obtains the processed application data, the second application may obtain the application identifier of the first application and decrypt the processed application data by using the application identifier of the first application.
If the first application adopts the asymmetric encryption algorithm to encrypt the third data, the public key and the private key used in the encryption process are inconsistent. Symmetric encryption algorithms herein may include, but are not limited to: SSH (secure Shell) algorithm, RSA (RSA algorithm) encryption algorithm, Elgamal algorithm, etc. In one embodiment, the second application may generate a public key and a private key, the private key being stored by itself, the public key being sent to the first application. After receiving the public key sent by the second application, the first application encrypts the third data by using the public key, so that the second application can decrypt the processed application data by using the private key stored by the second application.
And S606, selecting a picture format by the first application, and generating a data picture according to the processed application data and the picture format.
In one embodiment, a first application can arbitrarily select a picture format and acquire an image file structure of the picture format, wherein the image file structure comprises at least one data unit to be filled; and the first application fills the processed application data into the at least one data unit to be filled to generate a data picture. In an embodiment, the first application fills the processed application data into the at least one data unit to be filled, and a specific implementation of generating the data picture may be: the method comprises the steps that a first application determines a target data unit to be filled from at least one data unit to be filled and acquires data to be filled of the target data unit to be filled; the first application determines matched application data from the processed application data according to the data to be filled in of the target data unit to be filled in; and the first application fills the matched application data into a target data unit to be filled to generate a data picture.
S607, the first application stores the data picture in the terminal album, so that the second application obtains the data picture from the terminal album and obtains the application data according to the data picture.
For a specific process of the first application to store the data picture in the terminal album, reference may be made to step S204 in the above application embodiment, which is not described in detail herein.
It should be noted that, after the second application acquires the data picture, the second application may determine an image file structure according to the picture format of the data picture, and perform analysis processing on the image file structure to obtain the processed application data. Then, the second application can select the symmetric encryption algorithm or the asymmetric encryption algorithm adopted by the first application to decrypt the processed application data to obtain third data, and decompress the third data to obtain second data. The second application decomposes the second data to obtain the application data and the first data to be transmitted. The second application may use a one-way irreversible function (such as a hash function) to perform operation on the application data to be transmitted, which is obtained by decomposition, to obtain the operated application data, and then compare the operated application data with the first data, if the operated application data is consistent with the first data, it is determined that the application data is not tampered. If the application data are inconsistent with the application data, the application data are abandoned, and prompt information can be output to prompt that the application data acquired by the user are wrong and are modified, so that the user can retransmit the application data to the second application through the first application.
In the embodiment of the application, after the first application acquires the application data to be transmitted, the application data to be transmitted may be processed to obtain processed application data. Then, the first application can select a picture format, generate a data picture according to the processed application data and the selected picture format, and store the data picture in a terminal album, so that a second application obtains the data picture from the terminal album, and obtains the application data according to the data picture. Therefore, the application data processing method provided by the embodiment of the application can store the application data to be transmitted in the terminal album in a picture format so that the second application can obtain the application data from the terminal album, thereby realizing the transmission of the application data, avoiding occupying resources of a server, and realizing the transmission of the application data without depending on a network.
