Detailed Description
In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it should be understood that the drawings in the present application are for illustrative and descriptive purposes only and are not used to limit the scope of protection of the present application. Additionally, it should be understood that the schematic drawings are not necessarily drawn to scale. The flowcharts used in this application illustrate operations implemented according to some embodiments of the present application. It should be understood that the operations of the flow diagrams may be performed out of order, and steps without logical context may be performed in reverse order or simultaneously. One skilled in the art, under the guidance of this application, may add one or more other operations to, or remove one or more operations from, the flowchart.
In addition, the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. The components of the embodiments of the present application, generally described and illustrated in the figures herein, can be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the present application, presented in the accompanying drawings, is not intended to limit the scope of the claimed application, but is merely representative of selected embodiments of the application. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present application without making any creative effort, shall fall within the protection scope of the present application.
It should be noted that in the embodiments of the present application, the term "comprising" is used to indicate the presence of the features stated hereinafter, but does not exclude the addition of further features.
Before the proposal of the present application is made, in the prior art, in the process of transmitting a file, in HTTP, Basic access authentication (Basic access authentication) is a login verification method for allowing a web browser or other client program to provide an identity credential in the form of a user name and a password when requesting the file transmission, before the file transmission, a colon is added to the user name and then the password is concatenated, and the obtained result character string is encoded by using the Base64 algorithm. For example, if the user name provided is adadin and the password is open session, the result after splicing is that adadin is openeseme, and then the result is encoded by Base64, so as to obtain QWxhZGRpbjpvcGVuIHNlc2FtZQ ═ qwzq. And finally, sending out the character string coded by the Base64, decoding by the server to obtain a character string of a user name and a password separated by a colon, and acquiring a corresponding file according to the password.
However, while basic authentication is very easy to implement, this approach is based on the following assumptions: the connection between the client and the server host is secure and trusted. In particular, if transport layer security protocols such as SSL/TLS are not used, keys and passwords transmitted in the clear can be easily intercepted, resulting in the file being intercepted.
Fig. 1 is a schematic diagram of exemplary hardware and software components of a processing device that can implement the concepts of the present application according to an embodiment of the present application. For example, the processor 220 may be used on the electronic device 200 and to perform the functions herein. The electronic device 200 may be a general purpose computer or a special purpose computer, both of which may be used to implement the document processing method of the present application. Although only a single computer is shown, for convenience, the functions described herein may be implemented in a distributed fashion across multiple similar platforms to balance processing loads.
For example, the electronic device 200 may include a network port 210 connected to a network, one or more processors 220 for executing program instructions, a communication bus 230, and a different form of storage medium 240, such as a disk, ROM, or RAM, or any combination thereof. Illustratively, the computer platform may also include program instructions stored in ROM, RAM, or other types of non-transitory storage media, or any combination thereof. The method of the present application may be implemented in accordance with these program instructions. The electronic device 200 also includes an Input/Output (I/O) interface 250 between the computer and other Input/Output devices (e.g., keyboard, display screen).
For ease of illustration, only one processor is depicted in the electronic device 200. However, it should be noted that the electronic device 200 in the present application may also comprise a plurality of processors, and thus the steps performed by one processor described in the present application may also be performed by a plurality of processors in combination or individually. For example, if the processor of the electronic device 200 executes steps a and B, it should be understood that steps a and B may also be executed by two different processors together or separately in one processor. For example, a first processor performs step a and a second processor performs step B, or the first processor and the second processor perform steps a and B together.
The following describes specific implementation steps, principles and beneficial effects of the program anti-aliasing processing method according to the present application by using various embodiments.
Fig. 2 is a schematic flowchart of a file processing method according to an embodiment of the present application; fig. 3 is a diagram of a file fragmentation processing architecture according to an embodiment of the present application. The execution main body of the scheme of the application can be terminal equipment or a server. In some cases, when the file to be transmitted is a voice file in the ogg format, the voice file is mostly generated on the terminal device, for example: generated in a mobile phone or a recording pen, etc. Then, the terminal device can process the generated file by using the file processing method of the application, and send the processed file to the server for file analysis, file playing, file downloading and the like. In other cases, when other terminal devices request to obtain the target file from the server, the server may also process the target file by using the file processing method of the present application, and transmit the processed file to the corresponding terminal device.
Alternatively, as shown in fig. 2, the method of the present application may include:
s101, carrying out fragmentation processing on the original file to obtain a plurality of fragmented files.
In the present application, the original file may be a file in any format, for example: an ogg format file, an APE format file, an MPEG file format, etc.
Optionally, the original file is sliced, that is, the original file is divided into a plurality of subfiles. The size of the fragment can be set by self-definition according to actual requirements, and can also be adjusted adaptively.
And S102, adding the fragment information of the fragment file in the file header of each fragment file.
Optionally, a private protocol may be added in the header of each fragmented file, where the protocol content of the private protocol may be fragmentation information of the fragmented file, and the fragmentation information of each fragmented file may be unique. By adding corresponding fragmentation information to each fragmentation file, protection of each fragmentation file can be realized.
It should be noted that, by adopting fragmentation processing, fragmentation information is added for each fragmented file, and multiple fragmented files can be processed in parallel, which can reduce the performance consumption of the device and improve the processing efficiency of the file. On the other hand, the protection performance of the original file can be effectively improved, even if part of the fragmented files are intercepted, the complete original file still cannot be obtained, and the original file is prevented from being leaked.
As shown in fig. 3, the original file is divided into a plurality of fragmented files, each of which is composed of fragmentation information and a file stream, and the fragmentation information is added to the file stream header. Wherein, a file stream may refer to the file content of a fragmented file. Therefore, the fragmented files are protected through the fragmented information, and the original files are protected.
And S103, uploading each fragmented file added with the file header to a server.
Optionally, each fragmented file to which the header file is added may be packaged and uploaded to the server in batch, or each fragmented file may be independently uploaded to the server according to the time when the header file is added to each fragmented file. The uploading of the original file is realized in the form of uploading the fragmented file, so that the transmission safety of the original file can be improved, and the original file is protected.
To sum up, the file processing method provided by this embodiment includes: carrying out fragmentation processing on an original file to obtain a plurality of fragmented files; adding fragment information of each fragment file into a file header of each fragment file; and uploading each fragmented file added with the file header to a server. According to the method, the original file is subjected to fragmentation processing, and unique fragmentation information is added to each obtained fragmentation file, so that the fragmentation file added with the fragmentation information is uploaded to a server, and uploading of the original file is achieved.
Optionally, in step S101, performing fragmentation processing on the original file to obtain a plurality of fragmented files, which may include: and according to the preset byte size, carrying out fragmentation processing on the original file to obtain a plurality of fragment files, wherein the size of each fragment file is the preset byte size.
In an implementation manner, the original file may be fragmented according to a predetermined byte size, and the original file is divided into a plurality of files with the same size.
The byte size may be preset according to the original file size. For example: when the size of the original file meets the first threshold value, the byte size can be set to be the first byte size, so that the original file is subjected to fragmentation processing according to the first byte size, and a plurality of fragmented files are obtained. And when the size of the original file meets the second threshold value but is smaller than the first threshold value, the byte size can be set to be the second byte size, so that the original file can be subjected to fragmentation processing according to the second byte size to obtain a plurality of fragmented files.
Generally, the first byte size may be set to 65535 bytes and the second byte size may be set to 258 bytes. For example, when the original file size is 10M, the original file may be divided into 161 fragmented files according to 65535 byte size.
It should be noted that, for a plurality of fragmented files obtained by fragmentation, since the size of the original file and the size of the preset byte are fixed, there may be a case where the size of one fragmented file in the plurality of fragmented files is smaller than the size of the preset byte, but adding fragmentation information to the fragmented file is not affected.
In the embodiment, the original file is uniformly fragmented by adopting the preset byte size, and the fragmentation is not performed in a file stream format, so that the obtained fragmented file only contains one part of the complete fragmented stream, the head and the tail of the file stream are effectively separated, and the file content of the fragmented file cannot be correctly analyzed and obtained even if part of the fragmented file is stolen in the file transmission process.
Fig. 4 is a flowchart of another file processing method provided in the embodiment of the present application, and optionally, as shown in fig. 4, in the foregoing step, the fragmenting an original file according to a preset byte size to obtain multiple fragmented files may include:
s201, determining whether the byte size of the original file is larger than or equal to a preset byte size.
Optionally, when the original file is subjected to the fragmentation processing, it may be determined whether the size of the original file meets a preset condition, so that the fragmentation processing is performed on the original file meeting the preset condition.
Generally, whether the byte size of the original file is larger than or equal to the preset byte size can be judged according to the byte size of the original file and the preset byte size, and when the original file is too small and does not meet the fragmentation condition, the fragmentation processing of the original file has no practical significance.
And S202, if so, carrying out fragmentation processing on the original file according to the preset byte size to obtain a plurality of fragmented files.
When the byte size of the original file meets the preset byte size, the original file is fragmented according to the preset byte size as described above.
Optionally, the fragmentation information in step S102 may include: the sequence number of the fragment file and the size of the fragment file; step S102, adding the fragmentation information of the fragmented file in the file header of each fragmented file, which may include: and adding the sequence number of the fragment file in a first preset byte in the file header of each fragment file, and adding the size of the fragment file in a second preset byte.
In this embodiment, the fragmentation information of the fragmentation file is unique, and the fragmentation information of each fragmentation file may be determined according to the file size and the file content of each fragmentation file.
In an implementation manner, the fragmentation information may include a sequence number of the fragmentation file and a size of the fragmentation file, and then the fragmentation information may be added in a file header of the fragmentation file according to a preset rule according to the sequence number of the fragmentation file and the size of the fragmentation file.
Optionally, the sequence number of the fragmented file may also refer to a file sequence of the fragmented file corresponding to the original file, for example, the original file is formed by combining 1, 2, and 3 files in sequence, and then the sequence numbers of the three files also correspond to 1, 2, and 3 in sequence.
In the following, a method for acquiring the serial number of the fragmented file is first described: when the original file is sliced, a plurality of sliced files with consecutive numbers can be obtained by slicing, as shown in fig. 3, a sliced file 1, a sliced file 2 …, a sliced file n, and the like. And taking the number as the serial number of each fragment file according to the number corresponding to each fragment file.
Optionally, in this embodiment, a sequence number of the fragmented file may be added to a first preset byte in a file header of the fragmented file, and a size of the fragmented file may be added to a second preset byte in the file header. The first preset byte and the second preset byte may be one byte or two bytes, and may be specifically set according to a protocol rule of a private protocol.
For example: when the sequence number of the fragmentation file and the size of the fragmentation file set in the protocol rule are represented by 16-bit characters, the first preset byte may be two bytes so as to enable the complete addition of the sequence number of the fragmentation file and the size of the fragmentation file, and when the sequence number of the fragmentation file and the size of the fragmentation file set in the protocol rule are represented by 8-bit characters, the first preset byte may be one byte sufficient for the complete addition of the sequence number of the fragmentation file and the size of the fragmentation file.
It should be noted that the arrangement order of the first preset byte and the second preset byte may be arbitrarily adjusted, for example: taking the first preset byte and the second preset byte as two bytes, the first byte and the second byte add the sequence number of the fragmented file in the file header of the fragmented file, and the size of the fragmented file is added in the third byte and the fourth byte. Alternatively, the size of the slice file may be added to the first byte and the second byte, and the sequence number of the slice file may be added to the third byte and the fourth byte. The adding sequence of different fragmentation information is not specifically limited in the present application.
Optionally, the fragmentation information in step S102 may further include: the total number of the fragmented files, in step S102, adding the fragmentation information of the fragmented files in the file header of each fragmented file, which may further include: and adding the total number of the fragmented files in a third preset byte in the file header of each fragmented file.
The total number of the fragmented files, that is, the number of fragmented files obtained by performing fragmentation processing on the original file, is described. In this embodiment, the total number of fragmented files is not greater than 255. The total number of the fragmented files and the size of the fragmented files are corresponding to each other, and the total number of the fragmented files is used as one of the fragmented information, so that the transmission safety of the fragmented files can be further improved.
It should be noted that the total number of the fragmented files is usually less than 8-bit characters, and therefore, in this embodiment, the third preset byte may be one byte, which is used to add the total number of the fragmented files.
Similar to the above, the arrangement order of the first preset byte, the second preset byte and the third preset byte can be adjusted at will, and the application does not limit the arrangement order.
Optionally, the slicing information in step S102 may further include: the information digest value of the fragmented file, in step S102, adding the fragmentation information of the fragmented file in the file header of each fragmented file, which may further include: and adding the information digest value of the fragment file in the fourth preset byte in the file header of each fragment file.
In some implementations, the shard information of the shard file may further include an information digest value of each shard file, where the information digest value is associated with the file content of each shard file, and each shard file has a unique information digest value.
The information abstract value of the fragment file is mainly used for checking the integrity of the file, is not an abbreviation of the file content of the fragment file, but is a feature code obtained by performing mathematical transformation on the original fragment file according to a disclosed algorithm. This signature has the following properties, firstly it is irreversible, for example with a secret text such as: "xxxx" is transformed by an algorithm to obtain a feature code (xxxxxxx), and the feature code is informed to other people, so that the file content of the fragmented file can be determined according to the feature code.
In this embodiment, the information digest value may be an MD5 value, but is not limited to the MD5 value in practical application, and may also be an MD2 value, an MD4 value, or the like. Because the MD5 value is a 128-bit (bit) feature code, and the character string is long, the probability that the MD5 values corresponding to any two files are the same is extremely low, and the uniqueness of the files is ensured. Through the verification of the information abstract value, the complete fragment file can be effectively acquired.
Optionally, in this embodiment, the information digest value is expressed by an MD5 value, and then, the corresponding fourth preset byte may be 16 bytes, so as to be able to completely add the information digest value of the fragmented file.
Similarly, the arrangement order of the first preset byte, the second preset byte, the third preset byte and the fourth preset byte is not unique, that is, in the fragmentation information of the fragmentation file, the sequence number of the fragmentation file, the size of the fragmentation file, the total number of the fragmentation file and the information digest value of the fragmentation file may be arranged according to any rule. For example: the sequence numbers of the first byte and the second byte adding fragmentation files, the sizes of the third byte and the fourth byte adding fragmentation files, the total number of the fifth byte adding fragmentation files and the information digest values of the sixth byte to the 21 st byte adding fragmentation files. Or the sizes of the first byte and the second byte adding fragmentation files, the sequence numbers of the third byte and the fourth byte adding fragmentation files, the information summary values of the fifth byte to the 20 th byte adding fragmentation files, the total number of the 21 st byte adding fragmentation files and the like.
The different adding sequences of the fragment information have the same protection effect on the fragment files, the stealing of the original file can be effectively prevented by adding the fragment information to the fragment files, and even if all the fragment files are stolen, the complete file content can not be obtained by analyzing because the meaning of each byte in the added fragment information is not public, so that the effective protection of the file is realized.
Optionally, in this application, adding fragmentation information to each fragmentation file, where the fragmentation information is information related to the fragmentation file, may avoid adding additional information during file transmission, for example: and information such as user names, file passwords and the like does not need to be added. Therefore, the data transmission quantity can be effectively reduced, and the file transmission efficiency is improved.
Optionally, in step S103, uploading each fragmented file to which the file header is added to the server may include: uploading each fragment file added with the file header to a server through a preset protocol, so that the server analyzes each fragment file according to the preset protocol and combines the fragment files to obtain an original file.
Optionally, when uploading each fragmented file to which the header file is added to the server, the fragmented file may be uploaded according to a preset protocol, so that the server may parse each fragmented file according to a meaning represented by each byte in the header file specified in the protocol, and combine and restore the multiple fragmented files according to a sequence number of each fragmented file to obtain an original file.
It should be noted that the preset protocol may be an http transmission protocol, and through protocol transmission, security of information acquisition between the terminal device and the server may be ensured, and illegal acquisition of file information by other third-party devices may be avoided, so as to protect files during file transmission.
To sum up, the file processing method provided by the embodiment of the present application includes: carrying out fragmentation processing on an original file to obtain a plurality of fragmented files; adding fragment information of each fragment file into a file header of each fragment file; and uploading each fragmented file added with the file header to a server. According to the method, the original file is subjected to fragmentation processing, and unique fragmentation information is added to each obtained fragmentation file, so that the fragmentation file added with the fragmentation information is uploaded to a server, and uploading of the original file is achieved.
In addition, the fragmentation information is added to the fragmentation file, so that the addition of extra information during file transmission can be avoided, the data transmission quantity can be effectively reduced, and the file transmission efficiency is improved.
Finally, through protocol transmission, the security of information acquisition between the terminal equipment and the server can be ensured, and other third-party equipment is prevented from illegally acquiring file information, so that the file is protected in the file transmission process.
