Responsible use

Goal and impact

PZH-Assist has been developed as a secure alternative to ChatGPT and similar chatbots. PZH-Assist is only available to officials of South Holland province. PZH-Assist is intended as an assistant and has no direct impact on businesses and citizens. PZH-assist does not necessarily have a direct and major impact on citizens, as it is mainly used internally. However, the user determines the specific purpose for which PZH-assist is used.


The experiment has been completed. PZH-assist will remain available until the end of 2024.

Considerations

PZH-Assist mitigates a number of privacy risks that commercial language models do have. For example, the conversations and uploaded files are not used to train the language models. Furthermore, PZH-Assist does not monitor interface usage.

Human intervention

PZH-Assist is not used for automated decision-making. Employees ask questions and receive answers from the chatbot. Employees themselves are responsible for using the answers correctly.

Risk management

Privacy:

- Conversations and files are used to train language models. This risk is mitigated by the fact that we use a proprietary environment where the conversations and files are stored. The language models used also run in our own environment and do not learn from the calls and files.

- Monitoring interface usage. This risk is mitigated by the fact that we have built our own interface. This proprietary interface does not monitor interface usage.

- Extracting personal data from the underlying language model. Through a process of prompt engineering, we tried to extract third-party personal data from the underlying language model. From this process, this was not possible and the underlying security measures worked.

Elaboration on impact assessments

DPIA has been carried out and is now also signed off by the Data Protection Officer. Consent is subject to 12 months.

An IAMA is in preparation.
