SOUPS is an international conference in the fields of usable privacy and security. At SOUPS 2020, the acceptance rate was 19.8% (26/131).

Their paper, "Why They Ignore English Emails: The Challenges of Non-Native Speakers in Identifying Phishing Emails" discusses phishing attacks, which have become a serious global threat, to identify the challenges of non-native English speakers in Identifying English phishing emails, and proposes design implications that help them combat phishing attacks. In this paper, through an online survey with 862 non-native English speakers (284 Germans, 276 South Koreans, and 302 Japanese), we analyze users' behavior, perceptions in identifying English phishing emails. Our analysis suggests their concerns to deal with dealing with emails written in their non-native language: (1) difficulty understanding English email content, (2) difficulty identifying errors and unnatural language in English, (3) unfamiliarity with English phishing emails, (4) decreased attention in English contexts, and (5) difficulty finding similar cases in English on the Internet. To solve their concerns and minimize discrepancy in communication between native and non-native speakers, we present following design implications to develop assistive technologies: language-agnostic phishing knowledge base, Auto follow-up mechanism, Training on anti-phishing emails for non-native English speakers, and machine translation as an assistive tool.

NTT will continue to work on a fundamental theory that approaches the essence of human beings and information, as well as innovative technologies that will transform society, and promote the safe and secure society through R&D activities in security, privacy, and human factors.
