Data processing in connection with our hearing car
At the Fraunhofer IDMT in Oldenburg, we have been researching and developing methods for data security and technical data protection, such as acoustic anonymization strategies, for years. We are working on specific technologies for the requirements of the market, as modern vehicles have numerous driver assistance systems, such as cameras, lidar and radar, which help with parking or lane keeping. However, cars still lack a sense of hearing. However, it is very important to be able to perceive and classify outside noises in order to follow the traffic around you. To this end, we use our appropriately labeled test vehicles to record data with various sensors, including video and audio recordings in the vehicle interior and the vehicle environment.
1. Collection, processing and use of your personal data
Who is responsible for data processing?
The Fraunhofer IDMT Oldenburg Branch for Hearing, Speech and Audio Technology HSA (hereinafter referred to as “Fraunhofer IDMT in Oldenburg” or “Fraunhofer IDMT-HSA”), located in 26129 Oldenburg, Marie-Curie-Straße 2, as part of the Fraunhofer Institute for Digital Media Technology IDMT, located in 98693 Ilmenau, Ehrenbergstr. 31, is a legally non-independent institution of the Fraunhofer-Gesellschaft zur Förderung der angewandten Forschung e.V., 80686 Munich, Hansastraße 27c (registered under Munich VR 4461). The Fraunhofer IDMT is the controller within the meaning of the EU General Data Protection Regulation (“GDPR”) for the processing of personal data in connection with video and audio recordings relating to the development of assisted, connected, partially automated and autonomous driving functions.
What data do we collect and for what purpose?
The personal data mentioned here, which is collected through the use of our marked test vehicles on public roads, is processed as follows:
The test vehicles are equipped with various sensors, microphones and video cameras. Public road traffic (surroundings of the test vehicle) can be recorded on video and audio files and stored for further analysis and, if necessary, combined with other sensor data.
The audio recordings, such as from the siren, are used to recognize that the vehicle in motion must pull over in the event of an approaching emergency vehicle with the siren running and right of way. The video, audio and sensor data are used during the test drives to recognize road users and basic traffic scenarios and to act accordingly. In a further evaluation of the recordings, the video, audio and sensor data are used to develop and improve the algorithms for the assisted, networked, partially automated and autonomous driving functions.
The acoustic sensors on and in the vehicle process the audio data directly and only pass on metadata. While still on the sensor, the data stream also passes through a privacy filter that filters out speech components in the audio data. Conversations from passers-by inside and in the immediate vicinity of the car are therefore not included in the analysis. The Fraunhofer IDMT-HSA never identifies people in the data records.
What is the legal basis for this data processing?
The collection, processing and use of your personal data is based on a balancing of interests in accordance with Art. 6 para. 1 lit. f GDPR. The Fraunhofer IDMT-HSA has a legitimate interest in the processing of your data for the further development of driver assistance and information systems as well as automated driving functions and comfort functions. Information about your rights, including the right to object to the processing of your personal data, can be found in section 2 of this statement.
The video and audio recordings of the test vehicle environment are necessary to ensure the safe use of assisted, connected, partially automated and autonomous vehicles.
How long do we store the data?
We only store your personal data for as long as the respective purpose requires. If data is processed for several purposes, the data will be deleted or only stored in a form that cannot be traced back to you as soon as the last specified purpose has been fulfilled.
How is the data backed up?
We secure your data according to the state of the art. For example, the following security measures are used to protect your personal data from misuse or other unauthorized processing:
- Access to personal data is additionally technically restricted for a limited number of authorized persons for the declared intentions:
- Collected data is only transmitted in encrypted form.
- The IT systems for processing the data are technically isolated from other systems in order to make unauthorized access, e.g. through hacking, more difficult and to prevent it where possible.
- In addition, access to these IT systems is permanently monitored in order to detect and prevent misuse at an early stage.
Who do we share the data with?
We share the data with universities and other research institutes in order to work together in the field of research and development. As a large amount of data is required for analysis, we also share this with our cooperation partners. The transmission of video, audio and sensor data to our cooperation partners is subject to strict purpose restrictions (i.e. for development and research purposes in the field of highly and fully automated driving).
The Fraunhofer IDMT-HSA and its cooperation partners do not use the video, audio and sensor data to identify persons, as the identification of persons is not relevant for the development of assisted, networked, partially automated and autonomous driving systems. For the development of the platform for assisted, connected, partially automated and autonomous driving, it is only relevant and necessary that relevant environmental data is recorded for the driving task.
