8,955,150, "Apparatus and method for managing digital rights using virtualization technique," assigned to Fasoo (KR).
The present invention relates to an apparatus and a method for managing digital rights using virtualization technique, and more particularly to an apparatus and a method for enabling a user to access a desired text file in an independent area through a virtual machine corresponding to a licensed right for accessing the text file. The present invention comprises a virtual machine (VM) management unit for controlling a user access authorization function for accessing the text file in the area to which the virtualization technique is applied.
8,955,141, "Method of digital rights management about a compressed file," assigned to Fasoo (KR).
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.
