Title:
機密保護データ通信のための方法および装置
Document Type and Number:
Japanese Patent JP3877782
Kind Code:
B2
Abstract:
A user system (2) recognises data as being either secure or general (non-secure). The data may be for performing on-line transaction processing or banking via the Internet. The user system (2) transmits the secure data from an ISDN circuit (6) on the D-channel, and the general data on the B-channel. The digital exchange (8) routes the general data via the Internet (12) to a service provider (3). A frame handler in the digital exchange (8) recognises the secure data in the D-channel and routes it via a physically separate telecommunications link (20) to the service provider (3). The alternative route (20) may include a management function connected by leased lines on each side to the exchange (8) and the service provider (3). The service provider (3) merges the secure and general data and performs the usual transaction processing operations.
