This US News and World Report’s article, Digging through data for omens, addresses information gathering challenges inherent in the TSA’s new airline screening program, CAPPS II. The article states the program is… “a delicate dual challenge: accurately spotting suspicious patterns across multiple databases while minimizing false alarms and safeguarding individual privacy.”
Within the context of the privacy issue, the article mentions a joint study by the National Credit Reporting Association and the Consumer Federation of America, Credit Score Accuracy and Implications for Consumers (PDF). The report “found that 10 percent of credit reports contain errors in names or other identifying information–yet such reports are one of the tools the TSA will use to verify identity.”
