CAMBRIDGE, Mass. -- As new disclosures mount about government surveillance programs, computer science researchers hope to wade into the fray by enabling data mining that also protects individual privacy.

For example, manifests of airplane passengers could be compared with terrorist watch lists � without airline staff or government agents seeing the actual names on the other side's list. Only if a match were made would a computer alert each side to uncloak the record and probe further.
