Storage & retrieval of trusted information: A temporal probabilistic database approach

This paper proposes a data model for the management of information exchanged during trust negotiation. The information exchanged during trust negotiation has been considered to be structured or may be converted to a structured format Uncertainty associated with such information transfer has been modeled as probabilistic data Updating of message has been explained using a particular application domain. Effect of associating uncertainty to individual attributes and computation of overall uncertainty for a record has also been shown.
