DYNAMIC ACCESS CONTROL FOR DOCUMENTS IN ELECTRONIC COMMUNICATIONS WITHIN A CLOUD COMPUTING ENVIRONMENT

摘要

The present invention provides a solution to manage and control document transmission and electronic communication. Specifically, the present invention solves the problem of having control over data (documents, image files, and attachments hereafter referenced as “documents”) that are associated with multiple types of data communication. Along these lines, the present invention provides a hub and spoke communication model in order to achieve multiple benefits in terms of effectiveness, efficiency, flexibility, and control. This type of granular control is critical for information sharing within a Cloud computing environment. This approach is also useful for collaboration tools and can be augmented by the creation and management of access control lists (ACL) for the hub-spoke system. To this extent, this present invention solves the problem of being able to automatically update ACL's as documents are being forwarded or otherwise communicated between multiple people. These ACL's are kept up to date through the analysis of to whom (and where) a document has been sent.
