21世纪计算机技术和网络技术的飞速发展将地理信息产业带进了一个崭新的领域。地理空间信息服务成为解决数据异构、实现资源共享的有效途径。然而,随着地理信息服务在各领域的推广应用,传统分布式技术在开发地理信息网络服务中所面临的安全问题逐渐突显出来,已严重制约了网络服务在地理信息产业的发展。针对矢量数据服务在数据传输、服务操作、服务审计等阶段所面临的来自网络内部和外部的安全风险,应用WCF技术,深入地研究了矢量数据服务安全机制的构建与实现。
The rapid development of computer technology and network technology in the 21st century has brought the geoinformation industry into a completely new field. Geospatial information service has become an effective way to solve data heterogeneity and realize resource sharing. However, with the popularization and application of geographic information services in various fields, the security problems faced by traditional distributed technologies in the development of geographic information network services have gradually become prominent, which has severely restricted the development of network services in the geographic information industry. Aiming at the security risk of vector data service in the data transmission, service operation, service audit and other phases from the inside and outside of the network, WCF technology is applied to deeply study the construction and implementation of vector data service security mechanism.
