Abstract: In this talk, I will present some of the research projects

I’m currently involved with and their available opportunities. I will discuss problems associated with synchronizing specific events in space and time (X- coherence), fact-checking, and mining persons, objects and contents of interest from various and heterogeneous sources including — but not limited to — the internet, social media and surveillance imagery. For that, we seek to harness information from various media sources and synchronize the multiple textual and visual information pieces around the position of an event or object as well as order them so as to allow a better understanding about what happened before, during, and shortly after the event. After automatically organizing the data and understanding the order of the facts, we can devise and deploy solutions for mining persons or objects of interest for suspect analysis/tracking, fact-checking, or even understanding the nature of the said event. Additionally, by exploring the possible existing links among different pieces of information, we aim at further designing and developing media integrity analytics tools to hint at existing forgeries, sensitive content (e.g., violent content, child pornography), and spreading patterns of multimedia objects online. With demanding and sophisticated crimes and terrorist threats becoming ever more pervasive, allied with the advent and spread of fake news, our objective is to use the developed solutions to help us answering the four most important questions in forensics regarding an event: “who,” “in what circumstances,” “why,” and “how,” thus identifying the characteristics and circumstances in which an event has taken place.

Biografia: Anderson Rocha is an associate professor at the Institute of Computing, University of Campinas (Unicamp), Brazil. His main interests include Digital Forensics, Reasoning for Complex Data and Machine Intelligence. He has actively worked as a program committee member in several important Computer Vision, Pattern Recognition, and Digital Forensics events and is an associate editor of numerous top-tier international journals such as the IEEE Transactions on Information Forensics and Security (T.IFS) and the IEEE Security & Privacy Magazine. He is an elected affiliate member of the Brazilian Academy of Sciences (ABC), the Brazilian Academy of Forensic Sciences (ABC) and a two-term elected member of the IEEE Information Forensics and Security Technical Committee (IFS-TC). He is a Microsoft Research and a Google Research Faculty Fellow, important academic recognitions given to researchers by Microsoft Research and Google, respectively. In addition, in 2016, he has been awarded the Tan Chin Tuan (TCT) Fellowship, a recognition promoted by the Tan Chin Tuan Foundation in Singapore. He has been the principal investigator of a number of research projects in partnership with funding agencies in Brazil and abroad as well as national and multi-national companies having already deposited and licensed several patents. Finally, he is currently the Associate Director of the Institute of Computing at Unicamp, Brazil.
