Macrovision Corporation, the leading provider of copy protection and digital rights management ("DRM") technologies, today unveiled its new DVD version of SafeDisc during the Electronic Entertainment Exposition (E3 Expo) at the Los Angeles Convention Center. SafeDisc-DVD protects DVD-ROMs from unauthorized copying. SafeDisc is the most effective and widely used copy protection available for CD-ROMs, protecting over 70% of the top 20 PC games titles sold to retail in the United States, according to the NPD Techworld data for 2002. Once again demonstrating its industry leadership, Macrovision has extended the patented SafeDisc technologies for the growing DVD-ROM market to provide developers and publishers with a high level of copy protection for this higher capacity format. The number of DVD-ROM games available is growing rapidly due to the popularity of DVD-enabled consoles such as the Xbox and PlayStation2, and due to the increasing use of DVD media for PC games. While the current version of SafeDisc-DVD is optimized for PC DVD-ROM drives, the same technologies can be used as a second-level copy protection enhancement to the proprietary copy protection and security features that are used by console games manufacturers. SafeDisc is a software-based solution that does not require any changes to the publisher's application code and is compatible with standard PC or Mac environments and CD/DVD-ROM hardware. It is comprised of authenticating digital signatures embedded on the disc, an encryption wrapper, and various anti-hacking technologies that secure the CD/DVD-ROM executable. The patented SafeDisc digital signatures are added to each original disc during the mastering/replication process and prevent copying by standard optical disc writers. With a number of security options available, depending on the requirements of the publisher, SafeDisc DVD is extremely flexible. It can be set up to require the original DVD-ROM be present in the DVD drive each time the main application is accessed, or for the DVD-ROM to be inserted after a specified number of days, at the discretion of the publisher. Alternatively, the configuration can be formatted to lock the application to a particular PC, so that the DVD-ROM is only required for installation.
