Abstract:
The pervasive use of social networks has revolutionized how we connect, communicate, and share information. However, this convenience comes with inherent privacy and security risks that demand our attention. In this talk, we delve into the critical aspects of social network privacy and security, exploring the challenges and potential solutions. We discuss the detection of anomalous vertices and communities in complex networks, unveiling fake users and influential individuals. Additionally, we investigate the privacy vulnerabilities that arise from video conferencing, revealing the ease with which personal information can be extracted from publicly posted meeting images. Furthermore, we address the pressing concern of interruptions in video conferences and present an algorithm for detecting abnormal events. By shedding light on these issues and providing insights into safeguarding privacy and security, we aim to foster a greater understanding of the risks involved and encourage the development of effective measures to protect users in social network environments.
