Register criminal database

Judicial Information Service

The criminal justice database assists in determining leading identity in criminal cases. The personal details of a suspect or convicted person are stored in this system under a unique number supported by an algorithm.

Goal and impact

The purpose of the algorithm is to compare the supplied personalia with the data in the SKDB. There are too many sets of personalia coming in each day to perform the task manually, so an algorithm is used here as a tool. The added value of the algorithm in this process is that it saves a huge amount of time. It is impossible to manually match all supplied personalia. Also, deployment of the algorithm can prevent and/or reduce inaccuracies due to human actions.

Considerations

There are too many sets of personalia coming in every day to perform this task manually, so an algorithm is used here as a tool. The added value of the algorithm in this process is that it saves a huge amount of time. It is impossible to match all supplied personalia manually. Also, deployment of the algorithm can prevent and/or reduce inaccuracies due to human actions.

Human intervention

If there is a sufficient match, the algorithm automatically places the supplied personalia under an existing SKN. If only a possible match, i.e. without sufficient certainty, is found by the algorithm, there is always human intervention, examining the algorithm's results.

Risk management

Careful matching is important, which is why the algorithm is tested when changes are made. Correction requests and incidents indicating possible errors are investigated and lead to improvement proposals and enhancements where appropriate.

Legal basis

The legal basis for this task is Article 27b of the Code of Criminal Procedure and the Identity Determination of Suspects and Convicted Persons Decree.

Operations

Data

Your data will be used by the algorithm if you are convicted of a crime or suspected of a crime after your identity has been established. The data used are those supplied to the SKDB by other organisations in the criminal justice chain and those contained in the Basic Registration of Persons (BRP) or the Basic Provision of Foreigners (BVV).

Technical design

The algorithm follows the rules given to it by experts from the Judicial Information Service (Justid) in the field of identity determination. This is also known as a rule-based algorithm. Using these rules, the algorithm first checks whether there is sufficient similarity with an existing registration to which the new set of personal details can be automatically linked. If this is not the case, the algorithm uses the rules to check whether there are registrations of persons that have a lot of similarities with the supplied set of personal details. In the latter situation, this suggestion from the algorithm is submitted to a Matching Authority employee. The Matching Authority employee then examines whether the supplied set of personalia and the result found by the algorithm are the same person.
