Abstract

The present invention discloses a multimedia file processing method and device. The method comprises: firstly acquiring encoding information of a to-be-processed multimedia file; then selecting part of the encoding information as to-be-encrypted encoding information and performing encryption processing on the to-be-encrypted encoding information; and forming new encoding information by the encrypted encoding information and the unencrypted encoding information, and furthermore, performing encoding on the new encoding information to obtain a numbered multimedia file. According to the multimedia file disclosed by the scheme of the present invention, the user can decrypt and play a lossless multimedia file only if the user has the decryption authority corresponding to the multimedia file; therefor, even if the user with the decryption authority transmits a downloaded multimedia file to other users, the other users still can not play the lossless multimedia file if the other users do not have the decryption authority of the multimedia file, so that multimedia file copyrights are protected.
