1. A method for playing media data, applicable to a first terminal, the method comprising:
receiving a trigger instruction;
generating a second count value based on a stored first count value and a preset algorithm, and storing the second count value to overwrite the first count value, wherein the second count value is different from the first count value;
generating a first digest value based on a pre-stored authority identifier, the second count value, and a pre-stored key;
generating audio data carrying the first digest value, the authority identifier, and the second count value; and
playing the audio data, wherein the audio data is configured to instruct a second terminal to acquire the first digest value, the authority identifier and the second count value carried in the audio data, and send digital information comprising the first digest value, the authority identifier and the second count value to a server, such that the server performs the following:
calculating a second digest value based on the authority identifier, the second count value in the digital information, and a pre-stored key in the server; and in response to determining that the second digest value is the same as the first digest value in the digital information, legal authority identifiers stored locally in the server comprise the authority identifier in the digital information, and the second count value satisfies a preset condition with respect to the first count value corresponding to the authority identifier stored locally in the server, acquiring a pre-stored playback address of media data corresponding to the authority identifier and sending the playback address of the media data corresponding to the authority identifier to the second terminal,
wherein the second terminal is configured to acquire the audio data, acquire digital information, and play the media data based on the playback address.
