"A method of providing Resource-Event-Agent (REA) model based security, the method comprising: identifying an association between a first object and a second object in an REA model; creating an association class for the association between the first object and the second object, the association class defining security between the first object and the second object."
Yes, this patent (or is it still just an application for a patent?) is for associating a set of security properties to an association between to objects. Damn clever of them. Never would have thought of that.
