What you can learn from: Crime Fighter
by Jack Maple with Chris Mitchell
In Crime Fighter we learn that enforcing sound principles can turn a losing fight against crime into a winning fight. Using the four principles below, the NYPD dramatically reduced crime in just two years (from 1994 to 1996):
1) Accurate, timely intelligence. Everyday each precinct reviewed their crime statistics on a map that was posted in the station. At each level, decision makers were help responsible for the crime in their area. They would use the maps to help establish patterns and track down the criminals.

- Security is only as strong as the weakest link. If a crook can enroll as a provider without providing any credentials and can bill using a list of patients stolen from another provider, then all the computer network security in the world is not going to help you. If he can create believable bills, most of your sophisticated algorithms aren’t going to find him. Provider enrollment is just one of many very weak links in healthcare payment.
- Class breaks allow a perpetrator to attack several systems with the same ease as he can attack one system. The standardization required under HIPAA is going to make it easier for us to use fraud fighting algorithms developed for one plan to find fraud in another plan, but it will also make it easier for criminals to use the same exact scam in multiple places.
