Datamining and Terrorists: Use It?

I understand the privacy concerns.

Buit it is also provocative that:
'...Of the people with the 80 highest scores, five were among the Sept. 11 hijackers, Seisint's presentation said. Forty-five were identified as being or possibly being under existing investigations, while 30 others "were unknown to FBI." ...

What about those 30?

AP: Database Measured 'Terrorism Quotient'

By BRIAN BERGSTEIN, AP Technology Writer

NEW YORK - Before helping to launch the criminal information project known as Matrix, a database contractor gave U.S. and Florida authorities the names of 120,000 people who showed a statistical likelihood of being terrorists — sparking some investigations and arrests.

The "high terrorism factor" scoring system also became a key selling point for the involvement of the database company, Seisint Inc., in the Matrix project.

Public records obtained by The Associated Press from several states show that Justice Department (news - web sites) officials cited the scoring technology in appointing Seisint sole contractor on the federally funded, $12 million project.

Seisint and the law enforcement officials who oversee Matrix insist that the terrorism scoring system ultimately was kept out of the project, largely because of privacy concerns.

However, new details about Seisint's development of the "terrorism quotient," including the revelation that authorities apparently acted on the list of 120,000, are renewing privacy activists' suspicions about Matrix's potential power.

"Assuming they have in fact abandoned the terrorist quotient, there's nothing that stops them from bringing it back," said Barry Steinhardt, director of the technology and liberty program at the American Civil Liberties Union (news - web sites), which learned about the list of 120,000 through its own records request in Utah.

Matrix — short for Multistate Anti-Terrorism Information Exchange — combines state records and data culled by Seisint to give investigators fast access to information on crime and terrorism suspects. It was launched in 2002.

Because the system includes information on people with no criminal record as well as known criminals, Matrix has drawn objections from liberal and conservative privacy groups. Utah and at least eight other states have pulled out, leaving Florida, Connecticut, Ohio, Michigan and Pennsylvania.

The AP has received thousands of pages of Matrix documents in records requests this year, including meeting minutes and presentation materials that discuss the project in detail.

Not one indicates that Matrix planners decided against using the statistical method of determining an individual's propensity for terrorism.

When the AP specifically requested documents indicating the scoring system was scrapped, the general counsel's office for Florida state police said it could not uncover any.

Even so, people involved with Matrix pledge that the statistical method was removed from the final product.

"I'll put my 26 years of law enforcement experience on the line. It is not in there," said Mark Zadra, chief investigator for the Florida Department of Law Enforcement.

He said Matrix, which has 4 billion records, merely speeds access to material that police have always been able to get from disparate sources, and does not automatically or proactively finger suspects.

Bill Shrewsbury, a Seisint executive and former federal drug agent, said the terrorism scoring algorithm that produced the list of 120,000 names was "put on the shelf" after it was demonstrated immediately following Sept. 11, 2001.

He said the scoring system requires intelligence data that was fed into the software for the initial demonstration but is not commonly available. "Nor are we interested in pursuing that," he said.

The Utah documents included a Seisint presentation saying the scoring system was developed by the company and law enforcement officials by reverse engineering an unnamed "Terrorist Handbook" that reveals how terrorists "penetrate and in live our society."

The scoring incorporated such factors as age, gender, ethnicity, credit history, "investigational data," information about pilot and driver licenses, and connections to "dirty" addresses known to have been used by other suspects.

According to Seisint's presentation, dated January 2003 and marked confidential, the 120,000 names with the highest scores were given to the Immigration and Naturalization Service, FBI (news - web sites), Secret Service and Florida state police. (Later, those agencies would help craft the software that queries Matrix.)

Of the people with the 80 highest scores, five were among the Sept. 11 hijackers, Seisint's presentation said. Forty-five were identified as being or possibly being under existing investigations, while 30 others "were unknown to FBI."

"Investigations were triggered and arrests were made by INS and other agencies," the presentation added. Two bullet points stated: "Several arrests within one week" and "Scores of other arrests." It does not provide details of when and where the investigations and arrests took place.

Phil Ramer, who heads Florida state police's intelligence division, said his agency found the list a useful starting point for some investigations, though he said he could not recall how many. He stressed that the list was not used as the sole evidence to make arrests.

"What we did with the list is we went back and found out how they got on the list," Ramer said.

Dean Boyd, a spokesman for U.S. Immigration and Customs Enforcement, a descendant of INS in the Department of Homeland Security, said he could not confirm that INS used or was given the list.

Although Seisint says it shelved the scoring system — known as high terrorist factor, or HTF — after the original demonstrations in the wake of Sept. 11, 2001, the algorithm was touted well into 2003.

A records request by the AP in Florida turned up "briefing points," dated January 2003, for a presentation on Matrix to Vice President Dick Cheney (news - web sites) and other top federal officials delivered jointly by Seisint, Florida Gov. Jeb Bush and Florida's top police official.

One of the items on Seisint's agenda: "Demonstrate HTF with mapping." Matrix meeting minutes from February 2003 say Cheney was briefed along with Homeland Security Director Tom Ridge and FBI Director Robert Mueller.

In May 2003, the Justice Department approved Seisint as sole data contractor on the project, citing the company's "technical qualifications," including software "applying the `terrorism quotient' in all cases."

"The quotient identifies a set of criteria which accurately singled out characteristics related to the perpetrators of the 9-11 attacks and other terrorist events," said a memo from an Office of Justice Programs policy adviser, Bruce Edwards. "This process produced a scoring mechanism (that), when applied to the general criminal population, yields other people that may have similar motives."

A spokeswoman for the Office of Justice Programs declined to comment.

Ramer, the Florida agent, said the scoring system was scrapped because it was "really specific to 9/11," and not applicable for everyday use. Also, he said, "we didn't want anybody abusing it."

Seisint Inc., is a Boca Raton, Fla., company founded by a millionaire, Hank Asher, who stepped down from its board of directors last year after revelations of past ties to drug smugglers.

I'm not sure what, precisely, the privacy concerns should be.

I imagine many feel that folks who have committed no crimes should not gain the attention and possible monitoring/questionning/arrest from authorities. I.e., the government should not be analyzing everything it can about you. Where would it stop?

E.g., what if the Bush administration could identify all possible liberals?

But, if I understand this project properly, all it does is collate a bunch of information they already have from disparate sources. So, insofar as law-abiding citizens shouldn't be monitored, the Matrix thing isn't doing anything new.

As for the HTF, which may or may not be happening, is it sufficient for a warrant? My understanding from the article is that they'd use the list it produced to identify people. They would then have to find some evidence of a crime to start an investigation. Or am I misunderstanding the system? So, to put it in some concrete terms, if I make this watch-list, what privacies of mine will they intrude upon? Can they get a search warrant simply on the basis of this list or do they have to rely on evidence from my public life?
