English abstract:
In this paper we propose an e-voting authentication scheme
combined with QR-codes and visual cryptography. We focus on the us-
ability, in order to supply voters with less technical experience with a usable scheme. The only requirement is that the user needs to handle a device containing a QR-code reader, most probably a smartphone.
This approach is based on visual cryptography as the work horse: The
e-voting passwords for authentication are encoded as QR-codes and later encrypted into shadow transparencies. Thus, the transparency by itself conveys no information but when the layers are combined, the secret password is revealed.
