LONDON--(BUSINESS WIRE)--Aug. 28, 2003

Macrovision Corporation (Nasdaq:MVSN), leading provider of copy protection and digital rights management technologies, today announced the launch of SafeDisc(R) version 3.1, designed to upgrade its CD/DVD-ROM copy-protection against hacking and unauthorised copying of protected titles. SafeDisc V3.1 builds upon the security wrapper that PC games publishers have used to protect over 200 million CDs worldwide, and provides effective and time-efficient security tools for PC games developers themselves.

Key features include:

-- Unique instance-based security that creates individual new

security system for each title, and an improved code masking

technology which can be used to thwart hackers from

reverse-engineering Macrovision copy protection out of a

protected application.

-- Robust SafeDisc security API (Application Programming

Interface) with "Intelligent Protected Functions (PFNs)" and

improved interface, allowing faster and more effective

implementation.

-- Expanded Professional Services with on-site Macrovision

development engineer working along side your developers to

produce world-class highly secure implementation of SafeDisc

protection for each title. This also includes SafeDisc API

training, software installation pack and additional code tools

and methodologies to increase the level of protection that

developers can apply to their titles.

-- New unique signature for each title to foil copying to even

the most advanced optical disc burners.

Steve Weinstein, executive vice president of Macrovision, commented: "Our ongoing investment in research and development provides our SafeDisc customers with a constantly evolving product for more effective protection in a fast moving and ever changing market environment."

SafeDisc V3.1 will be available in September, 2003 to meet publishers' and developers' demand for the 2003 holiday season. For additional product information, contact: [e-mail].
