ABSTRACT:
A software computing based environment for providing secured authentication of media downloaded from a network or loaded from a media player includes two peer-mode operating virtual machines. The low-level virtual machine provides decoding and decryption functions whereas the high-level virtual machine provides application level functions such as user interface, input/output.
