Location-Aware Collaboration (02-Feb-2010)
A location-aware collaboration system and method which provides selective communication between users sharing a common digital asset is described. For example, once a digital document is send to multiple recipients, it's no longer protected from unauthorized use. A novel location aware collaboration protocol is disclosed. It provides the ability to dynamically change the protection attributes of digital documents after a target digital document is electronically distributed.
Location-Aware Collaboration
This system and method selectively executes a program embedded into an active digital document, tracks and grants scope-specific access to the target data or document using a location-aware policy. The following figures illustrates the key steps involved in implementing the capability to dynamically change protection attributes associated with the target active digital document while allowing a selective audience to access the multi-tier protected data. Each time the target active digital document is opened, a
validation
process embedded into the document is executed and the
protection
attributes are updated as appropriate.

A system and method of dynamically adapting the protection attributes of a digital asset such that new
usage models of the said digital asset can be supported after the said digital asset is distributed to a
variety of audiences.
