Document Access in a Multi-Party Information Management System
A multi-party information management system such as an electronic contract system deals with a large number of secure documents for many organizations.The access and retrieval of these documents for different organizational users are very complex.In this paper,we present a sequencing access model,that dictates who and when a given version of a document can be retrieved,viewed and acted upon along multi-party workflow processes.To effectively implement the access model,a novel counter-based access algorithm has been proposed to provide dynamic tracking of access privileges and priorities for different organizations participating in the workflows.To support secure search and retrieval of documents,a secure-indexing mechanism has been introduced to incorporate document access control information directly into search index.Using an XML-based search engine and a compound query generation technique to combine user role and organization information in search query,high-performance retrieval has been achieved very securely and efficiently in our information management system.
