Abstract

The invention provides an audio encryption method and device and an audio decryption method and device. The method comprises the following steps: selecting a plurality of audio segments with fixed frequencies as a secret key space, and formulating a secret key comparison table according to the secret key space; wherein different characters in the key comparison table correspond to a plurality of audio clips in the key space; integrating the audio clips in the key space into a player, acquiring account information of a user from a server by the player when the player requests a video or an audio, and acquiring the corresponding audio clips from the player according to the account information and a key comparison table; and the player embeds the obtained corresponding audio clips into an audio to be played according to the account information, and splits the audio clips into an audio file containing the user account information so as to encrypt the audio. According to the invention, theaudio clip containing the account information of the user is embedded into the audio, so that the screen recording source is effectively traced to restore the information of a stealer, and an anti-theft effect is achieved.
