Abstract: 

 

Our daily lives have been immersed in widespread online social networks (OSNs). As an open platform, OSNs typically allow all kinds of users to register accounts. Malicious attackers can easily join and post misleading information, often with the intention of influencing users' decisions in OSNs. To provide reliable information and improve the experience for legitimate users, we leverage emerging deep learning technologies to learn users' dynamic behavior and build models to distinguish between legitimate users and malicious users. Our deep learning-based approaches have been shown useful in different kinds of OSNs, including location-based social networks, online developer communities and online dating apps.
