IM4DEC : Identity Management for the Digital Emergency Call

UN convention Article 9 requires countries to take measures for the full and equal participation of persons with disabilities, including access to communication and information services. Despite this, there are still about 1 million deaf and hard of hearing persons in Europe who currently rely on outdated technology (e.g. fax) and help from others to make an emergency call.
DEC112 is a non-profit association that has designed and developed a standard-conform infrastructure (ETSI TS 103 479) for deaf emergency chats (ETSI TS 103 698). Since 2019, the association is now operating a system in Austria in collaboration with the Ministry of Interior that connects emergency chats to the appropriate emergency communication centre by utilising location information.
However, still a number of challenges exist that are addressed in our project:

  • Presenting a verified identity when delivering an emergency chat: replace current SMS verification with an eIDAS 2.0 compliant identity based on DIDs
  • Deliver relevant (pre-recorded) information in case of an emergency: extend current free-text stored on the smartphone with structured information stored securely online
  • Operators struggle with chat from deaf persons: introduce an AI-based chatbot to train users and share this information with emergency organisations as basis for new training material
  • Such data (identity, emergency information, training chats) are considered special category data under the GDPR and we will perform a formal DPIA (Data Protection Impact Assessment) for the end-to-end dataflow
  • This is not only for the benefit of deaf people but also individuals oppressed by domestic violence can make use of this technology through the use of a silent emergency notification; already in operation since 2022 in Austria we will provide an SDK to include this functionality in an EU Digital Identity Wallet to get such functionality on every phone.

EU Authorities addressed these topics in Regulation 2023/444 that require all member states to ensure accessible communication services to emergency services from 2025 onwards: with our project we make sure that such future solutions take special needs of the deaf community and oppressed individuals into consideration.
