AbstractThis 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.
