This document presents a research project outline focused on the security of personal data on the internet, specifically addressing data theft and privacy concerns related to social networking sites. The research problem is framed around the case study of Facebook and Cambridge Analytica, investigating the importance of securing online data and the preventive measures users can take. The project aims to determine the extent to which personal data is secured on social networking sites, the impact of online data theft, and the steps to mitigate these risks. Employing a mixed-methods approach, the research will collect both qualitative and quantitative data through primary sources like interviews and surveys, supplemented by secondary data from previous data theft instances. The sample includes various stakeholders such as politicians, Cambridge Analytica members, Facebook staff, and general internet users to ensure a comprehensive analysis.
