Goal and impact
The purpose of the algorithm is to protect DigiD users from abuse or improper use by quickly signalling whether DigiD is being misused. The signal given by the algorithm is a starting point for an investigation. If a DigiD is actively being abused, it can be revoked, suspended or blocked. This prevents further abuse. After revocation, citizens can apply for a new DigiD. A suspension or block can be lifted.
Considerations
The added value of this algorithm, is to identify and prevent abuse and improper use of DigiD. The confidentiality, availability and integrity of the data used are not violated. By law, the authority of Logius is established to signal abuse and improper use of DigiD.
Human intervention
The algorithm sends a signal. No automated follow-up takes place. The signal that goes off is the basis for (potentially) starting an investigation into the observed activity. Review and judgment follows an investigation conducted by several analysts. Depending on the outcome of the investigation, action may be taken to revoke, suspend or block DigiD. The citizen is always informed when the DigiD account is revoked, suspended or blocked.
Risk management
When a signal goes off it means further investigation is necessary. Not in all cases when the signal goes off there is abuse and improper use. Further investigation should always show that. The algorithm is evaluated at least every 6 months for usefulness, necessity and functioning.
The investigation into abuse and improper use consists of an analysis of DigiD use. Built into the process is that at least three people are involved in the investigation to avoid assumptions as much as possible. The maximum risk of the algorithm is that someone's DigiD is revoked, suspended or blocked. After a DigiD is revoked, the citizen is able to apply for a new DigiD and a suspension or blocking can be lifted.

Data
The following data is used in running the algorithm;
- A BSN that can be used to identify a person
- Usage data, including the IP address, successful and failed authentications
- Application data, including a unique app code (DigiD App instance_id) and a service provider identifier (Webservice_id)

- The algorithm uses sensor data to make a calculation for predictions of slipperiness risks. These predictions are used to determine where to grit (preventively), in consultation with meteorologists. In addition, the algorithm can issue various alarms, for example when there is a chance of wet road sections freezing.Last change on 19th of June 2025, at 12:38 (CET) | Publication Standard 1.0

- The algorithm marks personal data in documents. An employee manually checks everything and then instructs the marked info to be irreversibly removed or made unreadable. The documents can then be published, e.g. based on the WOO. This is low-risk, self-learning AI.Last change on 17th of June 2025, at 9:12 (CET) | Publication Standard 1.0

- This algorithm helps the ACM find price announcements in messages that might say something about tacit or explicit alignment. This information by itself does not trigger action, but it can be a reason for inspectors to further investigate a possible infringement.Last change on 4th of October 2024, at 13:36 (CET) | Publication Standard 1.0
