The server is provided with a plurality of sets of encryption and decryption algorithms in advance, each set of encryption and decryption algorithm has a respective ID interface, and the encryption algorithm/decryption algorithm can be directly called by inquiring the ID interface.
Preferably, the check code for each time of day may be generated in advance, and the corresponding algorithm ID may be randomly acquired.
Optionally, the verification codes, the encryption algorithm ID and the decryption algorithm ID of each period of time are loaded in the program of the server in a red-black tree mode to verify the verification codes between the recording equipment and the server, and the decryption algorithm and the generated verification codes are rapidly searched through the storage structure of the red-black tree.
Alternatively, to improve security, the check code and algorithm ID may be automatically refreshed once at 0 point per day.
Then, a generation module is arranged in the data server, the generation module generates random check codes according to time periods, each time period corresponds to one random check code, and each time period corresponds to one set of encryption and decryption algorithm.
Then, the random check code generated by the generation module of the data server and the acquired encryption algorithm ID and decryption algorithm ID are respectively input into the red-black tree data structure according to the segmentation of the time period. As shown in FIG. 6, according to the time period of every 5 minutes, the check code and algorithm ID corresponding to different time periods can be quickly found by adopting the red-black tree data structure.
And finally, the current recording equipment firstly transmits an uploading requirement to a server before uploading data, and the server confirms that the uploading requirement is transmitted by the equipment meeting the encryption condition, and then transmits a check code to the recording equipment. Because each recording device has its own device ID, the recording device carries its own device ID and current time stamp when sending the uploading demand, and the server judges that the device ID is held by the device meeting the encryption condition, and according to the time stamp carried by the recording device in the uploading demand. For example, timestamp: 2020-01-01:10:01:01, confirming that the time period is 10:00-10:05, and quickly searching a corresponding check code and algorithm ID from the time period to the red black tree data structure; and issuing the check code to the recording equipment.
After the current recording equipment acquires the check code, the audio data file and the received check code are together transmitted to the server. And the data server checks the uploaded audio data file by extracting the check code, and after the check codes are consistent, the data server inquires an ID interface of the uploaded audio data file according to the corresponding encryption algorithm ID, so that the corresponding encryption algorithm is called to encrypt the audio data file.
Optionally, when the user needs to download or query the encrypted audio data file, the user queries the ID interface of the encrypted audio data file by confirming that the corresponding decryption algorithm ID is acquired in the server in the uploading time period, so as to invoke the corresponding decryption algorithm to decrypt the audio data file.
