In this work, we examined the usability and trustworthiness of different electronic signature systems together with the technology commitment of the participants. The participants had to evaluate the following six signature systems: Web-based services, hardware-based systems (tokens), certificate-based signatures in e-mails, certificate-based signatures in PDF readers, eID-based methods, and Pretty Good Privacy (PGP)-based applications. The data were collected by using a service in Germany. Usability and trust scores were calculated for each signature system and evaluated with regard to correlation with the technology commitment score. We analyzed the correlation coefficients and found strong relationships between technology commitment and the rating of usability and trust with very high significance. Additional questions on new ideas, such as QR/URL-based placeholders for signatures, or the use of a blockchain to secure data against forgery, were asked. The survey results suggest that the use of blockchain technology would not have a significant impact on user trust. This observation also applies to the use of QR/URL-based signatures.     «
