Abstract
Systems and methods for joining results in loosely collaborative data exchanges which include a plurality of nodes in communication with each other wherein a node is constrained from sharing payload data regarding a first subject, is allowed to share matching data regarding the first subject, and is further constrained to be separate from the other nodes. In some embodiments, a method includes receiving a set of virtual results from the constrained node including the matching data and excluding the payload data. The method also includes receiving results from the other nodes and determining whether any of the results correspond to the same subject. The method also includes, when any of the results correspond to the same subject, joining the corresponding portions in a hub separate from the constrained node. The joined results can be output.
