first, the data server performs segmentation at regular intervals in units of days. Specifically, each time corresponds to a check code according to a time period cut before every day, and an encryption algorithm and a decryption algorithm are randomly used. 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 of each time of the day may be generated in advance, and the corresponding algorithm ID may be randomly acquired.
Optionally, the check code, the encryption algorithm ID, and the decryption algorithm ID of each time period are loaded in the program of the server in a red-black tree manner to check the verification code between the recording device and the server, and the decryption algorithm and the generated check code are quickly queried through a storage structure of the red-black tree.
Alternatively, to improve security, the check code and algorithm ID may be automatically refreshed at 0 o' clock every day.
Then, a generating module is arranged in the data server, the generating 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 algorithms.
And then, respectively recording the random check code generated by the generation module of the data server, the obtained encryption algorithm ID and the obtained decryption algorithm ID into a red-black tree data structure according to the segmentation of the time period. As shown in fig. 6, each 5 minutes is a time period, and the check code and the algorithm ID corresponding to different time periods can be quickly found by using the red and black tree data structure.
And finally, the current recording equipment sends an uploading requirement to the server before uploading data, and the server confirms that the uploading requirement is sent by the equipment meeting the encryption condition, and then sends 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 timestamp when sending the upload request, and the server judges that the device ID is held by the device satisfying the encryption condition, and carries the timestamp in the upload request according to the recording device. For example, the time stamp: 2020-01-0110: 01:01, confirming that the time period is 10:00-10:05, and quickly finding out the corresponding check code and algorithm ID from the time period to the data structure of the red-black tree; and issuing the check code to the recording equipment.
And after the current recording equipment acquires the check code, sending the audio data file and the received check code to the server together. And the data server checks the uploaded audio data file by extracting the check code, and after the check is consistent, the ID interface of the uploaded audio data file is inquired 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 ID interface is queried by confirming that the corresponding decryption algorithm ID is obtained in the server during the uploading time period, so as to invoke the corresponding decryption algorithm to decrypt the audio data file.
