Digital data wallets are user-centric platforms that enable users to control their privacy online. The relationship between trust and digital data wallets remains unclear. This study aims to examine factors that influence different trust targets. We constructed the research model based on a mixed methods approach. The qualitative study is used to identify antecedents of each trust target. We built the research model based on the network of trust model and the qualitative study results. The model will then be tested with data from three European countries - Austria, Romania, and Spain.
