数字矢量地图版权保护关键技术研究

Copyright protection technology is an effective measure that can keep down the fact that the digital vector maps are copied illegally, spread wantonly and maliciously tampered. Under the premise of ensuring the precision of the digital vector maps that is not altered, the existing copyright protection technology doesn't have the satisfying high robustness and practicality. So this paper studies and comes up with a satisfying digital vector maps copyright protection strategy. This paper attaches importance to combine Information Hiding theory with the Digital Watermarking technology and solves the practical problems such as the damage of Copyright embedded operations to the digital vector maps content, the unstoppable data illegally copying action, the trace to the infringed maps' original data source and the Responsibility Determination. The main contents of this paper are (1)the non-destructive Technology of Information Hiding based on the digital vector maps multiple characteristics fusion;(2)the digital vector maps reversible Copyright protection technology based on safe container;(3)the digital vector maps Copyright protection technology based on authentication. These three points are a hierarchical inheritance research system. It solves the data safe problems from production release, marketing communications to the right of full life cycle and takes into account the interests of map user and map producers.

数字矢量地图版权保护技术是防止地图资源被非法复制、肆意传播和恶意篡改的有效手段。在确保数字矢量地图的地理精度和关键内容不被改动的前提下，现有的版权保护技术还不达到令用户满意的实用化标准。因此，研究并提出满足实际需求的数字矢量地图版权保护策略；重点结合信息隐藏理论和数字水印技术，解决版权保护技术实施过程中的内容无损标准、满足遏制地图传播过程中的非法数据拷贝要求、具备被侵权地图原始数据来源追踪和责任认定的功能，研究的主要内容包括：（1）基于数字矢量地图多特征融合的无损信息隐藏技术；（2）基于安全容器的数字矢量地图可逆版权保护技术；（3）基于身份认证的数字矢量地图版权保护技术。以上三点内容作为一个层次递进的技术体系，在兼顾地图开发，传播、应用环境的前提下，拟解决数字矢量地图从生产发布、市场传播到售后维权全生命周期的数据安全问题。

数字矢量地图版权保护技术是防止地图资源被非法复制、肆意传播和恶意篡改的有效手段。在确保数字矢量地图的地理精度和关键内容不被改动的前提下，研究并提出满足实际需求的数字矢量地图版权保护策略是当前信息隐藏与地理信息系统交叉领域研究的重要课题之一。结合多特征融合、安全容器与攻防技术、身份认证与权限限制等理论与手段，本项目解决或部分解决了地图非法数据拷贝问题、被侵权数据来源追踪问题和失泄数据责任认定问题等，寻求把信息安全关键技术和信息隐藏共同作用于数据安全的可达途径，促进信息科学中数据安全领域某些问题的解决，已发表或录用论文10篇，待出版著作1本，获得黑龙江省科技进步奖二等奖一项，黑龙江省高校科学技术奖一等奖一项。
