DOI: 10.1109/ICSAI53574.2021.96641769781665426244http://hdl.handle.net/10230/55715This paper describes the architecture of a trust module for the interaction between human users and virtual characters. The module is part of a bigger project whose goal is that of creating virtual and truly realistic characters capable of interacting with human users. An example of such a virtual character is a computer rendered museum clerk that interacts with visitors. The role of the security module in the envisioned scenarios is that of providing trust, mainly regarding the identity of the human user, but also about the “identity” of the virtual character. In this paper we design (and describe the implementation) of an architecture in which human users identities are checked through face recognition and handled with verifiable credentials managed through a public blockchain. The project has been funded by the European Union and is under realization.application/pdfeng© 2021 IEEE. Personal use of this material is permitted.
