摘　　要：访问监控是监控服务的核心研究内容,是矢量数据版权保护实现的关键,能有效弥补数据解密后不再被保护以及数字水印技术事后检测的缺点。本文通过分析矢量数据访问过程,在数据输入、输出设置监控点,将访问监控内容分解为读取、保存监控以及发布、打印、拷屏等其他方式的输出监控,同时,本文对访问监控的监控机制、监控流程进行了深入探讨。Access monitoring is the core content of monitoring service,which is the key to realize copyright protection for Vector Data.Based on access monitoring,copyright protection on vector data can effectively make up for the disadvantages of data＇s being unprotected after decrypted and post-detection of digital watermarking technology.Through analyzing the access process of vector data,the author proposed clearly to set up monitoring points during data input and output,including loading,saving and other forms of output monitoring,such as releasing,printing,printing screen.Finally,the paper probes into monitoring mechanism and the monitoring process of access monitoring.
