ACM News Service: New Protocol Can Defuse Turf Wars Over Information Sharing Among Federal Agencies. It is a commonplace (and perhaps even valid) to say that people resist open-ness and sharing. The turf wars in organizations of all kinds are an easy source of evidence. I've hear it attributed to universal human nature, to culture and to individual fears of vulnerability and exploitation.
Whatever it is all about, I'm intrigued by development of a protocol that affords "gradual disclosure of information, which lowers the risk that an agency's interests will be harmed, while also building trust between the entities sharing data." The idea of Penn State's Dr. Peng Liu is that providing a trustworthy mechanism for gradual disclosure will allow the self-interest in information sharing to be engaged.
The technical approach involves using XML Web Services to deploy a protocol that makes the trust-building process attractive for assuring mutual, timely access to information that is valuable when shared. The Kansas City InfoZine staff article provides more on the protocol for "Trust-Based Secure Information Sharing Between Federal Government Agencies [JASIST 56, 3 (Feb. 2005), 283-298]." On the face of it, this seems like something that could be abstracted into some patterns that could be applied in diverse situations, Web Service based or not. I have a place where I need that, so I'm moving the article to the top of my literature-search hit list, along with other work of the Penn State S2 Group.
