Why there are maximum of (fe)males in a country

Tuesday, January 19th, 2010

Within Europe there is no such system as European Social Security Number or European Identification Number. A lot of countries have their own system, and other countries are struggling to get a system into place.

The struggle of some countries has to do with historical reasons and with privacy aspects. Unique identifiation is not always used in favour of the community. And some of the used identification systems contain privacy-sensitive information, among others date of birth, gender and/or place of birth, where older systems might even contain religious or other privacy-senitive information.

A wide range of countries use the combination of date of birth, gender identification and the political region where you are born. In such a mechanism it is most common that part of the identification number is a 2-digit or 3-digit serial number to identify the unique male or female born on a specific date (or born on a specific month). Some countries provide odd serial numbers for male, and even for female. Bulgaria is the only one that wants “odd” females. Some countries like to divide on range (0-499 male, 500-999 female).  And some countries like Norway make nice combinations to include the century of birth or period of birth in the serial number.

The “miracle” of customer data integration

The more a company knows about its customer’s wishes, needs and habits and the more that company is able to tailor its proposition accordingly, the greater the value it will eventually provide for its customers. We all know that there are countless examples where defective, fragmented, or just plain poor customer data cause unnecessary costs, decrease in revenue, employee dissatisfaction or frustation, damage of the corporate image and many other unsdesirable or painful consequences.

Customer data quality and integration problems impact every area of the value chain of organisations. Far too often companies have a multiple view of their customers. Customer Data Integration (or MDM for Customer Data) is the key to providing companies with a single view of their customer. (more…)

Any close encounters with the FBI terrorist watchlist?

Monday, August 17th, 2009

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.

What’s the value of unique identifiers

Thursday, October 16th, 2008

In a survey by Human Inference processes were discovered to be the most challenging data quality aspect.

Since in processes often unique identifiers are used to identify customers, accounts or data in general the reliability of these identifiers influence the quality of your process. To avoid incorrect results and decisions a check of the data related to the identifiers is required. The illegal use of such an identifier leads to polluted data. A name-number-check should be implemented for e.g.:

  • bank account numbers
  • social security numbers
  • chamber of commerce numbers
