Abstract: A method for ranking politically exposed persons and/or other persons and entities that pose a heightened risk based on their importance wherein an exposure index is determined for each person in the population as a function of the existence or absence of a relationship with each of the other members of the population and each of one or more exposure factors such as position held by the person, country in which the position is held, and source of information about the person. The politically exposed persons in the population are ranked in accordance with their respective exposure indexes. The population is sorted and a subset of the population containing those politically exposed persons having exposure indexes indicative or the highest likelihood of illicit financial activity is thereby identified.

Abstract: A system for providing access to data. The system comprises at least two data centers. Each data center including a processing computer effective to receive first data, the first data including patient identification data. The processing computer further effective to de-identify the first data to produce de-identified data. A database is in communication with the processing computer. The database is effective to receive and store the de-identified data. A central processor is in communication with the at least two data centers over a network, the central processor is effective to receive a query from a user computer, forward the query to the at least two data centers, receive responsive data from at least one of the data centers as a result of a search of the de-identified data, and forward the responsive data to the user computer.
