基于WebService的遥感数据流监控系统

随着遥感技术的不断发展,遥感数据普及应用程度逐步提高,海量遥感数据安全和版权问题面临着巨大的挑战。由于WebService技术的跨平台性和低耦合等优势,其对处于复杂网络环境中的监控系统有着重要的作用,因此,通过WebService技术实现对数字水印加密过程的监控具有一定的研究意义。以Java EE的三层结构为设计思想,文中开发了一套基于B/S架构的数字水印加密监控系统,通过模块化的编程,实现了3种功能:水印实时监控、叛逆者追溯、水印操作情况统计。其主要的服务用WebService接口提供,具有异构程序耦合性及高可靠性和可扩展性,更适合当前网络技术的发展。通过对WebService技术的研究及海量遥感数据流的特点设计出了更为实用、可靠的监控系统,在保证系统稳定的前提下,提高了开发效率及数据监控的实时可靠性。

Remote Sensing Data Flow Monitoring System Based on WebService

With the continuous development of remote sensing technology,the popularization and application of remote sensing data are gradually increasing,and the security and copyright of massive remote sensing data are facing enormous challenges.Because of the cross-platform and low coupling,the WebService technology plays an important role in the monitoring system in the complex network environment. Therefore,it has certain research significance to realize the monitoring of digital watermarking encryption process through WebService technology.Based on the three-tier structure of Java EE,we develop a digital watermarking encryption monitoring system based on B/S architecture.Through modular programming,it achieves three functions of real-time watermarking monitoring,traitor tracing and watermarking operation statistics. Its main service is provided by WebService interface,with heterogeneous program coupling,high reliability and scalability,which is more suitable for the development of current network technology. Through the research of WebService technology and the characteristics of massive remote sensing data stream,a more practical and reliable monitoring system is designed to improve the development efficiency and real-time reliability of data monitoring on the premise of ensuring the stability of the system.
