ABSTRACT:
A great deal of intellectual property is currently handled digitally, in the from of audible, visual, or audio-visual files or data streams. With today's powerful electronic equipment and communication networks such as the internet, this digital content can be reproduced flawlessly and distributed without control. While attemps have been made to protect such digital content, none of the existing protection techniques have been successful. The invention provides a system and method of protecting digital content by integrating the digital content with an executable software package such as a digital media player, executing some sort of protection mechanism (such as password, watermark or encryption protection), and then encoding the software into a tamper-resistant form. In this way, the digital content can be used by initiating the executable software it was encoded with, but the content itself cannot be accessed, nor can the protection mechanism be cracked.
