  FIDO Transaction Confirmation is an extension for the FIDO authentication protocols to enable the verification and signing of digital transactions, e.g., for online banking. The standard currently considers only to include a transaction message text in the assertion which is signed by the user’s authenticator. However, this is not useful for more complex transactions and leaves room for ambiguities that might lead to security vulnerabilities. Therefore, we propose to include the transaction information to the FIDO protocols in a structured data format with a strictly defined schema to validate and sign transactions more reliably and securely.

  Technological advancements allow biometric applications to be more omnipresent than in any other time before. This paper argues that in the current EU data protection regulation, classification applications using biometric data receive less protection compared to biometric recognition. We analyse preconditions in the regulatory language and explore how this has the potential to be the source of unique privacy risks for processing operations classifying individuals based on soft traits like emotions. This can have high impact on personal freedoms and human rights and, therefore, should be subject to data protection impact assessment.
