Intersection Attacks on Discrete Epochs
… of user messaging simulated from a generated social graph. This thesis compares the success of the state of the art intersection attack using a model simulated from a generated social graph versus models simulated from real social graphs, such as those of Twitter and Google+. We find that …

Learning to de-anonymize social networks
Releasing anonymized social network data for analysis has been a popular idea among data providers. Despite evidence to the contrary the belief that anonymization will solve the privacy problem in practice refuses to die. This dissertation contributes to the field of social graph de-anonymization …

Partitioning social networks for data locality on a memory budget
"Typical queries on online social network (OSN) applications are complex and require ""feeds"" to be compiled with timely information about many friends and friends' friends, which may be stored across many servers. Partitioning the OSN social graph in such a way as to promote data locality, i.e. …

Mining User Behavior in Social Environments
… the Web 2.0 has brought to a widespread use of social media systems and to an increasing number of active users. This phenomenon implies that each user interacts with too many users and is overwhelmed by a huge amount of content, leading to the well know “social interaction overload” problem. In …

Human-Centric Spatio-temporal Modeling and Analysis for Multimedia Data
… into the 3D realm, I introduced an Interpolation Graph Convolutional Network, a technique inspired by the foundational operations of convolutional neural networks, to efficiently distill and interpret features from 3D point cloud data. This foundation is crucial for building upon in the subsequent …

Optimizing search user interfaces and interactions within professional social networks
Professional social networks (PSNs) play the key role in the online social media ecosystem, generate hundreds of terabytes of new data per day, and connect millions of people. To help users cope with the scale and influx of new information, PSNs provide search functionality. However, most of the …

Privacy engineering for social networks
… I enumerate several privacy problems in online social networks (OSNs) and describe a system called Footlights that addresses them. Footlights is a platform for distributed social applications that allows users to control the sharing of private information. It is designed to compete with the …

Supporting meaningful social networks
Recent years have seen exponential growth of social network sites (SNSs) such as Friendster, MySpace and Facebook. SNSs flatten the real-world social network by making personal information and social structure visible to users outside the ego-centric networks. They provide a new basis of trust and …
