Smart cities are nowadays producing a massive amount of data from environmental cameras, microphones and other sensors that remain unprocessed. Therefore, many AI-based solutions are recently emerging to support new smart cities’ applications, from dangerous event detection to statistics extraction for decision making. However, these data may contain sensitive personal information, calling for responsible AI solutions.
We proposes some privacy-preserving AI-components enabling responsible use of this data, by preventing unauthorised usage of personal data at both data storage and transmission under the context of Smart Cities. The proposed technologies are developed for the EU H2020 MARVEL project. Both video and audio anonymisation components are deployed at the edge level, enabled by a model compression component for complexity reduction. We discuss each component’s technical challenges, current progress, and future directions.
