CNet News blogger Declan McCullagh writes about a new study from the National Research Council on whether data mining works to identify and flag terrorists. According to McCullagh, data mining just gives too many false positives to make it reliable. The authors of the report recommend agencies follow some steps to improve data mining results:

From his blog:

* U.S. government agencies should be required to follow a systematic process to evaluate the effectiveness, lawfulness, and consistency with U.S. values of every information-based program, whether classified or unclassified, for detecting and countering terrorists before it can be deployed, and periodically thereafter.

* Periodically after a program has been operationally deployed, and in particular before a program enters a new phase in its life cycle, policy makers should (carefully review) the program before allowing it to continue operations or to proceed to the next phase.

* To protect the privacy of innocent people, the research and development of any information-based counterterrorism program should be conducted with synthetic population data... At all stages of a phased deployment, data about individuals should be rigorously subjected to the full safeguards of the framework.

* Any information-based counterterrorism program of the U.S. government should be subjected to robust, independent oversight of the operations of that program, a part of which would entail a practice of using the same data mining technologies to "mine the miners and track the trackers."

* Counterterrorism programs should provide meaningful redress to any individuals inappropriately harmed by their operation.

* The U.S. government should periodically review the nation's laws, policies, and procedures that protect individuals' private information for relevance and effectiveness in light of changing technologies and circumstances. In particular, Congress should re-examine existing law to consider how privacy should be protected in the context of information-based programs (e.g., data mining) for counterterrorism.
