Alternatively, the method can be applied to a terminal capable of calculating data, such as a mobile phone, a tablet computer, a notebook computer, a PC and the like, or intelligent hardware, such as intelligent tablet, intelligent recording equipment and the like. The terminal or 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 the wireless network comprises: WIFI and other networks that enable wireless communications. The wired network may include, but is not limited to: wide area network, metropolitan area network, local area network. The server may include, but is not limited to, any hardware device that can perform the calculations.
Alternatively, the above-described audio encryption method may be applied, but not limited to, in the course of audio transmission. Such as a live broadcast field, or a recording field, in which audio to be transmitted may be a service-generated sound recorded in a restaurant, a sound of a worker recorded in a store, or the like. The present embodiment is not limited.
Taking recording a sound generated by a restaurant service and carrying out encryption transmission of the sound as an example, in the scheme, after an original audio file to be encrypted recorded by recording equipment 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, wherein the second audio file is a file which is successfully encrypted and can be transmitted, and the second audio file is further transmitted, such as being sent to a server for storage and the like.
Optionally, the original audio file in the scheme may be a file recorded in real time, or may be a file recorded completely.
Alternatively, in the scheme, a real-time recorded file or an executable file in a recorded file, such as a bin file, can be used as an original audio file, encrypted and transmitted.
Alternatively, the obfuscated data in the present scheme may be a meaningless scrambling code of the same type as the file data of the original audio file.
Alternatively, in this scheme, when the mix-up data is inserted into the original audio file, the target position may be determined in the original audio file.
There are a variety of methods for determining the location of the target.
For example, one or more positions may be randomly determined in file data of an original audio file, and the determined positions may be 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 and after any one or more of the original audio subfiles.
Taking splitting the original audio file into three original audio subfiles as an example, the original audio subfiles 1, 2, and 3 are respectively. 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 listed here. The method can select to insert one confusion data or insert a plurality of confusion data each time the confusion data is inserted, and can randomly determine the quantity of the confusion data inserted each time the confusion data is inserted. For example, when the mix-up data is inserted after the original audio subfile 1 and before the original audio subfile 2, three mix-up data may be inserted after the original audio subfile 1, 1 mix-up data may be inserted before the original audio subfile 2, etc.
Alternatively, after the mix-up data is inserted into the original audio file, the first audio file is obtained, and then the order of the file data in the first audio file may be adjusted. In the adjusting process, a configuration file can be obtained, and a plurality of preset rules can be pre-stored in the configuration file, wherein each preset rule is used for adjusting the sequence of 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 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 is searched according to the number of the plurality of 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 splitting the first audio file into 6 pieces, the first rule is acquired as the target rule, and then the 6 first audio subfiles of the first audio file may be swapped in order according to the first rule. If the first audio sub-file and the second first audio sub-file are in the exchange order, finally obtaining the second audio file.
After the second audio file is obtained, the second audio file is transmitted to the original audio file. And sending the second audio file, the confusion data, the insertion position of the confusion data and the target rule to a receiver, and after the receiver receives the second audio file, reversely adjusting the sequence of the file data in the second audio file according to the target rule. If the target rule indicates that the first sub-file and the third sub-file in the first audio sub-file are exchanged in sequence, the first sub-file and the third sub-file in the first audio sub-file are reversely adjusted to be exchanged in sequence, so that the first audio file is obtained. And then deleting the confusion data from the first audio file according to the insertion position of the confusion data to obtain an original audio file, and realizing the decryption process of the file. After obtaining the original audio file, the recipient may 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 staff, and the client can record the sound of the staff. After the recording is finished, the original audio file can be obtained.
After the original audio file is obtained, a configuration file can be obtained from the server, wherein the configuration file comprises confusion data and preset rules. After obtaining the obfuscated data, the target location is first determined in the original audio file, which may be split into multiple original audio subfiles, and then one obfuscated data is inserted before each original audio subfile. The original audio file 202 is split into a plurality of original audio subfiles 204 as shown in fig. 2, and then the obfuscated data 206 is inserted, resulting in a first audio file 208 after the obfuscated data 206 is inserted. Then, the first audio file 208 is split again to obtain a plurality of first audio subfiles 210, then the order of the plurality of first audio subfiles 210 is adjusted according to the 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 order 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, the original audio file 202 is obtained, and the original audio file 202 is played or the original audio file 202 is stored. Optionally, before the second audio file 212 is transmitted in step S202, the second audio file 212 may be compressed and then transmitted, and the server receives the second audio file 212 and then decompresses and decodes the second audio file.
