Abstract: 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.

Abstract: A portable evidence preservation system for storing and transporting forensic evidence, in particular items containing blood, fibers, hair, and semen samples, in one or more generally energy-efficient, cool, dry, contaminate-free, isolated chambers. The system includes a housing having a plurality of chambers for storing and transporting forensic evidence therein, an HVAC unit for providing, and desirably recirculating, a supply of air through the chambers and for maintaining the supply of air at a predetermined temperature and at a predetermined humidity. A plurality of HEPA-type filters separately filters the supply of air to each chamber. The cool, dry air in the chambers inhibits and reduces the rate of the growth of bacteria which can destroy DNA and other proteins in the items of evidence containing blood and semen samples. The HEPA-type filters are effective to reduce cross-contamination between items in a chamber and between items in different chambers.
