We report in this article on name matching experiments, in particular on hit rates. We matched a sample of 631’845 fictitious customers aigainst PEP profiles (Politically Exposed Person).  A hit is a match between a customer and at least one PEP profile independent of the correctness of the match. A correct match (also called true positive) means that the customer is eventually the PEP described in the profile. A false match (also called false positive) means that the customer and the PEP are two different persons with very similar or identical names. The hit rate is the portion of customers for which a match was found. The chart shows how the hit rate is affected by taking into account date of birth and country information.

The names of the fictitious customers including their date of birth and their nationality have been extracted from en.wikipedia.org. The PEP profiles do not include the profiles of relatives and close associates.

Matching Results 384

The hit rates shown in the charts above correspond to the following configurations:

Only politically exposed persons were considered for which their date of birth and their nationality are known, i.e. only high quality profiles (hqp) of PEP. Date of birth (dob) and country (nationality and country of residence) were required to match.

Date of birth (dob) and country (nationality and contry of residence) were required to match. In the case of missing dob or country information, the match was not excluded.

Date of birth (dob) and country (nationality and contry of residence) were *not* required to match.

Nothing but the family name were required to match. Thus, many matches are obtained with different first names, dates of birth, and country codes.

The last hit rate was included, because we are occasionally asked, why eCPM does not support checks without first names. From the very high hit ratio it is evident that checking without first names is not recommended.

Complete Revision of the Federal Data Protection Act

The complete revision's draft of the Federal Data Protection Act is currently in political consultation. Data Protection is to be increased by giving people more control over their private data as well as reinforcing transparancy regarding the handling of confidential data.
