Digital content security system
First Claim
1. A method of securing digital content on a hard drive of computer, comprising:
- providing a physical key adapted to be carried by a user;
detecting the physical key wit a receiver/decoder circuit communicating with the hard drive;
validating the detected physical key with the receiver/decoder circuit wherein validating includes determining whether or not the detected physical key is associated with the hard drive; and
permitting access to the hard drive or a portion thereof with the receiver/decoder circuit if the detected key is validated wherein digital content read from or written to the hard drive is decrypted or encrypted by the receiver/decoder circuit using the detected physical key in order to provide sector-level protection.

Abstract
A Personal Digital Key Digital Content Security System (PDK-DCSS) is used to protect computers from unauthorized use and protect the digital content stored on computers from being wrongfully accessed, copied, and/or distributed. The basic components of the PDK-DCSS are (1) a standard hard drive device, with the addition of a PDK Receiver/Decoder Circuit (PDK-RDC) optionally integrated into the hard drive'"'"'s controller, and (2) a PDK-Key associated with the PDK-RDC. The PDK-Key and RDC technology is utilized to provide two categories of protection: (1) hard drive access control for providing Drive-Level and Sector-Level protection and (2) operating system-level independent file protection for providing File-Level and Network-Level protection.

9. A system for securing digital content on a hard drive of a computer, comprising:
-
a physical key adapted to be carried by a user; a hard drive having digital content; and a receiver/decoder circuit communicating with the hard drive for detecting and validating the physical key wherein the receiver/decoder circuit validates the physical key by determining whether or not the detected physical key is associated with the hard drive wherein the receiver/decoder circuit decrypts or encrypts digital content read from or written to the hard drive using the physical key associated with the hard drive in order to provide sector-level protection. - View Dependent Claims (10, 11, 12, 13, 14)

15. A method of securing a hard drive of a computer, comprising:
- providing a portable, physical key adapted to be carried by a user, wirelessly detecting the portable, physical key with a receiver/decoder circuit communicating with the hard drive when the key is in proximity to the receiver/decoder circuit;
validating the detected portable physical key with the receiver/decoder circuit; and
permitting access to the hard drive or a portion thereof with the receiver/decoder circuit if the detected portable physical key is validated wherein digital content read from or written to the hard drive is decrypted or encrypted by the receiver/decoder circuit using the key associated with the hard drive.
- providing a portable, physical key adapted to be carried by a user, wirelessly detecting the portable, physical key with a receiver/decoder circuit communicating with the hard drive when the key is in proximity to the receiver/decoder circuit;
