Abstract
Provided is a method for digital rights management of a compressed file created by compressing one or more original files. The method include the steps of: generating right information on an encrypted compressed file during the encryption of the compressed file by a digital rights management server; checking the user right to the compressed file by controlling a predetermined compression application program by a controller module installed in a user terminal when the user terminal to which the encrypted compressed file is downloaded opens the compressed file using the compression application program; requesting the digital rights management server to provide a certificate to decrypt the encrypted file by the controller module of the user terminal; generating the certificate according to a certificate request from the user terminal and sending the generated certificate to the user terminal by the digital right management server; and decrypting the encrypted compressed file by the controller module of the user terminal based on the received certificate.
