针对当前测绘成果管理分散、服务效率低等问题,基于FTP与SSL传输协议,利用矢量数据脱密和数字水印嵌入技术设计了矢量数据的安全处理机制,给出了一种矢量数据的水印模型。在此基础上,利用OAIS模型和工作流机制设计了基础测绘成果管理分发工作流机制。为检验方法的有效性,将该技术集成到具体的基础测绘成果管理系统中。结果表明,给出的矢量数据水印方法和数据分发工作流机制是可行的,有助于保障基础测绘数据的安全,提高基础测绘数据成果分发服务的工作效率和科学管理水平。

Using FTP and SSL protocols, a watermarking model for vector data was proposed in this paper. We designed the security mechanism of vector data using vector data decryption and digital watermark embedding technology. On this basis, using the OAIS model and the workflow mechanism, we designed a distributed mechanism for basic surveying and mapping results. To verify the validity of this method, we used the method in basic surveying and mapping results based management system. The results show that the vector data watermarking methods and data proposed in this paper and distributed workfl ow mechanism are feasible, which is helpful to guarantee security of the basic surveying and mapping data and enhance efficiency and scientific management level of the basic surveying and mapping data distribution service work.
