Technical Data Protection and Data Security
Ensuring security and data protection objectives such as confidentiality, integrity/authenticity, anonymity or pseudonymity, unobservability, etc. also plays an important role, especially when processing audio and video data inside and outside trains - whether it is processing and recognizing speech on trains, recognizing people, training and using AI-based acoustic event recognition or securely transmitting media data and associated metadata. These goals can be achieved through the use of IT security standards, cryptography and privacy enhancing technologies (anonymization, differential privacy, homomorphic encryption).
