Patent attributes
A digital forensic search tool which enables a first entity, such as a federal investigation agency, to share its suspect and sensitive data with a second entity, such as another investigative agency, in a manner that allows the second agency to utilize the suspect data while not revealing the actual content of the sensitive data to the second agency. The second agency can perform comparisons and other operations on the sensitive data without having to know the actual content of the data. The search tool allows an investigative agency to define an investigative strategy for a particular case via the search markup language programs and by the data features that it includes in the search tool. Thus, by sharing search tools among agencies, an agency can share or inform others of that agency's theory of the case and investigative goal.
