摘　　要：本文旨在解决现有施工项目集中式图档协同工作系统中的安全问题。通过需求分析确定施工项目分布式图档协同工作系统所应具有的特征,然后综合应用加密技术、身份认证技术、数字权限管理技术建立系统的安全机制,设计并实现了系统化,并进行了模拟试用。结果表明,该系统能够解决施工项目多参与方协同工作系统中设计方知识产权保障问题。This paper aims to solve the security problem of existed centralized web-based collaborative system on drawing documents.Requirement analysis was carried out to determine the feature of the distributed web-based collaborative system on drawing documents in construction projects.Then the security mechanism of the system was established based on several information security technologies such as encryption,identity authentication,digital rights management.Based on the mechanism,the system was designed and implemented.In addition,a simulating use of the system was carried out to verify its feasibility and effectiveness.The result shows that the system can protect the intellectual property of the designer.
