SECURE FILE SHARING OVER MULTIPLE SECURITY DOMAINS AND DISPERSED COMMUNICATION NETWORKS

摘要

System and method of obtaining data in a system in which share volumes of the data are dispersed across a communication network. A first computer requesting the data forwards the request to a second computer. The second computer determines if another computer has reassembled the data, and if so, responds to the first computer that the request cannot be granted. Otherwise, the second computer enables the first computer to access personal information associated only with a user of the first computer that authorizes the user to access the data. The personal information is used to determine reassembly information necessary to reassemble the data. The reassembly information is used to reassemble the data. The personal information may then be destroyed. The reassembled data is dispersed across the communication network. New personal information is created for the user.
