Goal and impact
The purpose of the algorithm is to enable risk-based monitoring of the Telecommunications Act and the Radio Regulations. The algorithm assesses the correctness of broadcast messages by vessels equipped with an Automatic Identification System (AIS). This is done using registrations from the maritime categories of inland, maritime and pleasure navigation. This methodology contributes to risk-based monitoring and ensures better use of inspectors' available time. The Algorithm does not currently result in an action or decision within the supervision process. In addition, it is still under further development.
Considerations
Due to limited capacity, it is not possible to annually inspect all registrars with maritime registrations (±55,000 registrations) for compliance with the Telecommunications Act and the Radio Regulations. Inspectors therefore have to choose which locations and target groups to inspect. That choice relies on knowledge and experience, which is time-consuming and difficult to transfer to new colleagues. The algorithm can quickly and independently, using large amounts of information, suggest which locations and target groups could be inspected.
Human intervention
The outcome of the algorithm is a summary of findings found by the algorithm based on broadcast AIS messages. Three fields of the AIS message are assessed by the algorithm, namely the ship's name, call sign, and MMSI number. An inspector uses this list for information and, based on the findings, determines what action can or should be taken according to the Surveillance Policy.
Risk management
The outcome of the algorithm is a list of findings identified by the algorithm based on broadcast AIS messages. An inspector uses this list for information to assess compliance behaviour and, based on the findings, decides what action to take within the monitoring process.
Legal basis
The Telecommunications Act is a Dutch law that sets rules for (providers of) communication networks and services. Among other things, it regulates user protection, providers' duty of care for safety and security and sets obligations for network operators.

Data
There are two sources of information used by the algorithm. The first source is the observed messages sent by the vessel, this contains the MMSI number, call sign and ship name covered by the Telecommunications Act and the Radio Regulations. The second source is the internal registration database where registration holders enter their data themselves using their accounts.
Technical design
The algorithm works on the basis of a decision tree. The decision tree compares the content of observed AIS messages with the expected content based on the registrations. When one or more of the attributes ship name, call sign or MMSI number do not match the registered data, this is recorded. That information is then reviewed by a human to determine compliance or non-compliance.
