s102, acquiring an original audio file to be encrypted;
s104, inserting confusion data into the file data of the original audio file to obtain a first audio file, wherein the data type of the confusion data is the same as that of the file data of the original audio file;
s106, adjusting the sequence of file data in the first audio file according to a target rule to obtain a second audio file;
and S108, determining the second audio file as a file obtained by encrypting the original audio file.
Alternatively, the method may be applied to, but not limited to, a terminal capable of calculating data, such as a mobile phone, a tablet computer, a notebook computer, a PC, or the like, or intelligent hardware, such as an intelligent card, an intelligent sound recording device, or the like. The terminal or the smart device may interact with the server through a network, which may include, but is not limited to, a wireless network or a wired network. Wherein, this wireless network includes: WIFI and other networks that enable wireless communication. Such wired networks may include, but are not limited to: wide area networks, metropolitan area networks, and local area networks. The server may include, but is not limited to, any hardware device capable of performing computations.
Alternatively, the audio encryption method can be applied to the audio transmission process without limitation. Such as the live broadcast domain or the recording domain, in which the audio to be transmitted may be the voice of a waiter recorded in a restaurant, or the voice of a staff recorded in a shop, etc. The present embodiment is not limited.
Taking recording of sound of a restaurant waiter and encrypted transmission of the sound as an example, in the scheme, after an original audio file to be encrypted recorded by a recording device is obtained, confusion data is inserted into file data of the original audio file to obtain a first audio file, then the sequence of the file data in the first audio file is adjusted according to a target rule to obtain a second audio file, the second audio file is a file which is successfully encrypted and can be transmitted, and the second day audio file is further transmitted, for example, sent to a server for storage and the like.
Optionally, the original audio file in the present scheme may be a file recorded in real time, or may also be a file that is recorded.
Optionally, in the present solution, an executable file in a file recorded in real time or a recorded file, such as a bin file, may be used as an original audio file, encrypted, and transmitted.
Alternatively, the obfuscated data in the present scheme may be a piece of meaningless scrambling code of the same file data type as the original audio file.
Alternatively, in the present scheme, when the obfuscated data is inserted into the original audio file, the target position may be determined in the original audio file.
The determination of the target location may be performed in a variety of ways.
For example, one or more positions may be randomly determined in the file data of the original audio file and used as target positions, or after the file output of the original audio file is split to obtain a plurality of original audio subfiles, one or more confusion data may be inserted before or after any one or more original audio subfiles.
Taking the original audio file split into three original audio subfiles as an example, the three original audio subfiles are an original audio subfile 1, an original audio subfile 2 and an original audio subfile 3. The obfuscation data may be inserted before or after any one or more of the original audio subfiles 1, 2, and 3. Such as inserting the obfuscation data before the original audio subfile 1, inserting the obfuscation data before the original audio subfile 3, or inserting the obfuscation data before the original audio subfile 2 and after the original audio subfile 3, or inserting the obfuscation data after the original audio subfile 1 and before the original audio subfile 2, etc., all of which are not recited herein. Each time the obfuscated data is inserted, one obfuscated data or a plurality of obfuscated data may be inserted, or the number of obfuscated data inserted each time the obfuscated data is inserted may be randomly determined. For example, when the obfuscated data is inserted after the original audio subfile 1 and before the original audio subfile 2, three obfuscated data may be inserted after the original audio subfile 1, 1 obfuscated data may be inserted before the original audio subfile 2, and so on.
Alternatively, after inserting the obfuscated data into the original audio file, a first audio file is obtained, and then the order of file data in the first audio file may be adjusted. In the adjusting process, a configuration file can be obtained, a plurality of preset rules can be prestored in the configuration file, and each preset rule is used for adjusting the sequence of the file data in the first audio file. The file size of the first audio file can be obtained, then a target rule matched with the file size is searched according to the file size, then the sequence of file data in the first audio file is adjusted by using the target rule, or the first audio file is split into a plurality of first audio subfiles, then a preset rule corresponding to the number of the split first audio subfiles is searched according to the number of the split first audio subfiles to serve as the target rule, and the sequence of the file data in the first audio file is adjusted.
For example, after the first audio file is split into 6 audio files, and the first rule is acquired as the target rule, the 6 first audio subfiles of the first audio file may be transposed according to the first rule. For example, the first audio subfile is transposed with respect to the second first audio subfile, and the second audio file is obtained.
And after the second audio file is obtained, the second audio file is the original audio file to be transmitted. And after receiving the second audio file, the receiving party firstly carries out reverse adjustment on the sequence of the file data in the second audio file according to the target rule. If the target rule indicates that the first subfile and the third subfile in the first audio subfile are exchanged in sequence, the sequence of the first subfile and the third subfile in the first audio subfile is reversely adjusted and exchanged back, so that the first audio file is obtained. And then deleting the obfuscated data from the first audio file according to the insertion position of the obfuscated data to obtain an original audio file, and realizing the decryption process of the file. After the original audio file is obtained, the receiving party can play the original audio file.
The following description is made with reference to fig. 2 in conjunction with a specific example.
The scheme can be applied to the client, the client can be worn by workers, and the client can record the sound of the workers. After the recording is finished, the original audio file can be acquired.
After the original audio file is obtained, a configuration file may be obtained from the server, where the configuration file includes obfuscated data and a preset rule. After the obfuscated data is obtained, the target location is first determined in the original audio file, the original audio file may be split into multiple original audio subfiles, and then one obfuscated data is inserted before each original audio subfile. As shown in fig. 2, the original audio file 202 is split into a plurality of original audio subfiles 204, and then the obfuscated data 206 is inserted, after the obfuscated data 206 is inserted, a first audio file 208 is obtained. Then, the first audio file 208 is split again to obtain a plurality of first audio subfiles 210, and then the sequence of the plurality of first audio subfiles 210 is adjusted according to a first rule to obtain a second audio file 212, after the data is transmitted to the server in step S212, the server first restores the second audio file 2121 to the first audio file 208 according to the first rule, and the restoring process is to reversely adjust the sequence of the first audio subfiles 210. After the first audio file 208 is obtained, the obfuscated data in the first audio file 208 is deleted to obtain the original audio file 202, and the original audio file 202 is played or stored. Optionally, before the second audio file 212 is transmitted in step S202, the second audio file 212 may also be compressed and then transmitted, and the server receives the second audio file 212, decompresses the second audio file 212 first, and then decodes the second audio file.
Through the embodiment, the method achieves the effect of improving the encryption and decryption efficiency of the audio file.
