Optical discs are the preferred media for storing and distributing digital information, especially software. The pervasive use of these discs in motivated by their low cost coupled with their versatility and durability. But advances in circuit technology have also boosted software piracy by making it easy to create high-fidelity copies of optical discs. Thor is a security scheme that aims to prevent unauthorized disc duplication and any illegal use of the data. Thor relies on a combination of software and hardware strategies using time-tested c ....etc

Introduction
Until recently, the diverse and well-established domains of Personal Computers (PC), Web (Internet), Consumer Electronics (CE) and Broadcast domains have had their own autonomous realms of existence. Each of these domains spawned their own characteristic and individualistic ways of managing and doing things, with examples as diverse as the application specification to the very notion of interactivity. However, lately there has been considerable interest among these domain communities to share and adopt in ....etc

ABSTRACT
The Extensible Markup Language (XML) is considered as the de facto standard for information processing and exchange on the Internet and in the enterprise services domain. The standardization bodies of the Internet domain such as W3C and OASIS have defined specifications for cryptography-based security solutions using XML technology that is mainly aimed for web applications. This prasentation presents various scenarios where XML Security can be applied to ....etc

HIGH DEFINITION OPTICAL DISC TECHNOLOGY
Current Media Format
CD’s
Consist of pits and lands stamped out in a spiral pattern on the disc.
A laser then reads the pits and lands.
The change from a pit to a land or a land to a pit indicates a one while no change indicates a zero.
Current Media Format (Cont.)
CD-RW’s
Consist of a metal phase change alloy which when heated can be to change to reflectivity
CD-R’s
Consist of a dye that is applied to the disc.
When a writing laser is shined it change ....etc
