Abstract: Systems and methods are disclosed for determining whether a third party observer could determine that an organization has an intent with respect to subject matter based on the organization's web activity. The determination that there is a risk of information leaks to the third party observer can be completed by analyzing the entropy of web usage information destined for the third party observer's servers.
