The invention relates to a system and method providing access of one or more heterogeneous digital contents to at least one offline Digital Rights Management (DRM) user by a DRM server. This invention involves establishing the trust relationship among the DRM server, DRM client, user's machine and the end user by means of digital certificate. The server generates protected digital content by means of using a standard encryption algorithm. The invention further involves determining whether a license for accessing the protected file is requested by the legitimate user, and if so, generating a license consisting the user rights and the protected decryption key to be downloaded by legitimate user. The DRM client decrypts the protected file using a decryption key of the license, and renders the content to the end user by calling the appropriate and customized viewer during consumption. |
