The present invention relates to a recording file segment encryption method, device, computer equipment and storage medium; wherein, the method includes: starting the recording pen, and recording the recording time T1 at the same time; The recording time T1, the unique serial number DSN of the recorder, the size of the recording file DSZ, the recording duration DT, and the unique serial number FSN of the audio file are integrated into a file TS and sent to the application; upload the file TS and user ID to the server; File TS and user ID, calculate and generate several seeds, then form a segment code, and send the segment code to the application program; the application program receives the segment code, and sends the segment code to the recorder; the recorder takes out the segment code The seed in is used as the secret key to encrypt the recording file segment by segment. The invention uses randomly generated seeds as secret keys to encrypt recording files in sections, thereby improving the encryption performance.
