Identity Resolution at the Federal Information Technology Center (ITZBund)
This is how 5,000 tax offices search for identification numbers.
Initial situation
In 2008, every resident of the Federal Republic of Germany received a unique, lifelong identification number for taxation purposes, which replaced the conventional tax number.
§ 139b of the German Fiscal Code (AO) specifies which personal data the Federal Information Technology Center (ITZBund) processes for this purpose (surnames, first names, date of birth, main residence, etc.).
Pioneer of digital administration
Introduction of error-tolerant search
To enable tax authorities to search the database intelligently, the ITZBund relies on matchmaker from exorbyte. The data required for setting up the central database in the ITZBund were transmitted by the relevant registration authorities. At the beginning of the project, the database contained approximately 110 million entries and has since grown to 450 million entries - and the trend is still rising. Today, the technology is used in various tax procedures.
Search for identification numbers
In an elaborate selection process matchmaker convinced with all requirements. In particular, the introduction of identification numbers required sophisticated duplicate identification and exact matching. More than 5,000 tax offices throughout Germany use the central database to search for identification numbers or to make corresponding search queries. With matchmaker, the authorities have a lightning-fast, error-tolerant search across multiple fields at their disposal, which can be used to search according to a wide variety of criteria – for example, name, date of birth, location.
Smart Technology
matchmaker is a high performance matching technology, which is particularly suitable for large data volumes and high query loads. The technology is deployed on top of existing database systems, works in the back-end of these systems and offers extensive configuration options. Thus matchmaker efficiently utilizes existing hardware and software resources. The engine can be seamlessly integrated into a mainframe environment. Thus, with matchmaker, the ITZBund is excellently positioned for future challenges.
