A concise definition

The technical data that are processed to conduct and invoice/bill for electronic communication, such as your IP address or MAC address.

Want to know more?

The name-, number- and/or address-related data of the sender or receiver of the communication are used to establish the communication. The network over which the communication is conducted (BASE) converts these data in order to compose the electronic message. From that moment we call it 'traffic data'.

Specifically, the traffic data pertains to the routing, duration, time or volume of the communication, the protocol used, the location of the sender or receiver's device, the network on which the communication originates or ends and the start time, end time or duration of the connection. These may also be embedded in the format in which the network transmits the communication.

A concise definition

Intelligent algorithms that process data to make decisions without human intervention.

What does BASE do?

BASE does not make automatic decision-making - whether or not based on profiling - that has legal consequences for you or where such a decision has consequences for you:


  • it is necessary to enter into an agreement with you.
  • For example: to check creditworthiness.
  • it is necessary to execute your agreement.
  • For example: to purchase BASE products and services in the event of non-payment.
  • the legislation allows it.
  • For example: to detect tax fraud
  • you have given your explicit permission for this.

In such cases, we will inform you about how the automated decision is made. You can then request human intervention or challenge the decision.
