Any close encounters with the FBI terrorist watchlist?

tsc080105aJust before this summer the U.S. Department of Justice filed a report about the FBI Terrorist Watchlist. This watchtlist serves as a critical tool for screening and law enforcement personnel for alerting them when they come across a known or suspected terrorist. It is used by personnel at airports, harbours and the borderline. Also when you apply for a visum you are matched against this watchlist. The Terrorist Screening Center, a subsidiary of the FBI, is responsible for maintaining the watchlist.

This watchlist was created in 2004 from several other lists and at that time it consisted of about 68.000 entries. I use the word entries, because in the years after it became fuzzy if one record is the same as one individual. By the end of 2008 the list had grown to over 1,1 million entries. In 2008 after the American Civil Liberties Union (ACLU) mentioned that the list had passed the 1 million, the government came with an explanation. Although we have recorded over 1 million entries in the database, the net result is that these records correspond to about 400.000 individuals. Terrorist often use different and thus multiple identities, use several (falsified) passports etc. But adding entries with only the first initials and last name, while an entry of the full first names and last name already exists will result in unwanted side-effects.

Bi-lingual streetnames in Amsterdam, do we really need it?

StraatnaambordSo once in a while I visit Amsterdam and have a drink or two in the centre. Afterwards I use the tram to get back to the hotel. This weekend I was quite surprised to find out that all the streetnames are announced in English, at each stop. The easy and obvious one is of course Centraal Station, which was translated to Central Station. I also can see how they came up with Rembrandt Square instead of Rembrandtsplein. But translating “Spui” to “Courtyard with a chapel” doesn’t help any tourists to find their destination. Continue reading ‘Bi-lingual streetnames in Amsterdam, do we really need it?’

The importance of persistent identification

A much overlooked issue in Customer Data Integration projects is “Persistent Identification”.

Persons and companies are very often identified using their address data. But, what do you do if a person has moved from address A to address B. One, thing you really don’t want is that the person is added to database as a new person (INSERT). From that moment a duplicate person or company resides in your system. This should be prevented, by creating searching indexes which include the current and the previous address of the persons and companies in your database.
