Entertainment and Communication Services on Broadband Become More Accessible

Tokyo, December 11, 2001 – Sony Computer Entertainment Inc. (SCEI) announced today that it would commence commercial services of Dynamic Network Authentication System (DNAS) for copyright protection and security for broadband business applications on the PlayStation®2 platform. These services are offered to game software developers, publishers and network business providers.


Through combination of IDs unique to individual PlayStation 2 units and IDs unique to each PlayStation 2 disk, DNAS authenticates user IDs and manages copy protection for digital content on the network. In July 2001, SCEI started test runs for DNAS to bring into operation the authentication system using these IDs. At the same time, the company has provided DNAS client modules to game developers and publishers who have been developing network services and have jointly conducted field tests. From this fall, the company has extended DNAS trial operations to Square Co. Ltd.’s PlayOnline beta test for authentication and coding of content. In addition to user ID authentication and content copy management, DNAS also provides many other functions such as parental lock function and time-based access control.
