As the communication and information technologies (especially mobile devices) have become a central part of our daily lives, people have started to bring their own devices to schools, universities, companies and other types of organizations. Bearing in mind the difficulty of stopping people from carrying these devices, Bring Your Own Device (BYOD) represents a paradigm shift, presenting new ways for organizations to function and offering several advantages to businesses, notably a reduction in hardware costs. Although BYOD (allowing people to bring their technological devices to schools or workplaces) sounds simple in words, BYOD implementations come with their own challenges (security related problems being the first). This study aims to analyze the perceptions of a group of South Korean undergraduate and master students (n=110 in total) of BYOD implementations in schools and in workplace separately. The study instrument had three sections; (i) basic demographics (age, gender and currently attending education level), (ii) 12 survey items on a Likert scale for BYOD perception at school questions, and (iii) 12 survey items on a Likert scale for BYOD perception at workplace questions. After the analyses of demographics, separate independent sample t-tests were applied in order to check if each set of 12 items for BYOD at school and at workplace significantly differ for gender and education level variables. While no significant difference was revealed based on gender variable, education level demonstrated differences on certain items. At the end, the 12 items for BYOD at school and BYOD at workplace were compared by applying paired samples t-tests to the dataset where significant differences were also observed for some items. The general results showed that participants supported BYOD in schools more than BYOD at workplace. Besides, master students showed more trust than undergraduate students on cyber-security both at school and at workplace.
