Abstract
Over the last few years, with an increase in the adoption of mobile phones amongst older adults - especially in Singapore - their limited knowledge of the digital world and products not designed with older adults in mind, put them at higher risk of cyberattacks and giving away unintended private information. Designing in this area requires the knowledge of the day-to day experience of older adults. To address this multi-disciplinary issue, the author embarked on a three-phase design research inspired by the British Design council’s Double Diamond Design Methodology. In the first phase the author interviewed 10 older adults and 10 adults who have supported older adults with mobile privacy and security (PS) and identifies various socio-cultural factors which affect how older adults experience and navigate PS online. In the subsequent phase, the issues are further refined and 18 stakeholders from the Design, HCI and security disciplines are invited to co-design ideas via participatory design sessions. Next, these ideas are embedded to design a hypothetical application design - SociAI (Social + CrowdSourcing + AI) - which aims to solve the problem of phishing links through a multi-modal approach. 30 older adults and adults assessed the usability of SociAI and rated it as having significantly higher usability as compared to current trust mechanisms in Android mobile browsers
