Talk: Multimedia Phylogeny Concepts for Media Provenance Analytics

Earlier today Prof. Anderson Rocha gave a talk at Purdue University, where he has been hosted by Prof. Edward Delp. The talk title is “Multimedia Phylogeny Concepts for Media Provenance Analytics”.

Abstract: Currently, multimedia objects can be easily created, stored, (re)-transmitted, and edited for good or bad. In this sense, there has been an increasing interest in finding the structure of temporal evolution within a set of documents and how documents are related to one another overtime. This process, also known in the literature as Multimedia Phylogeny, aims at finding the phylogeny tree(s) that best explains the creation process of a set of near-duplicate documents (e.g., images/videos) and their ancestry relationships. Solutions to this problem have direct applications in forensics, security, copyright enforcement, news tracking services and other areas. In this talk, we explore solutions for reconstructing the evolutionary tree(s) associated with a set of visual documents, more specifically images and videos. This can be useful for aiding experts to track the source of child pornography image broadcasting or the chain of image and video distribution in time, being extremely useful for complex different media provenance tasks.

The call of the talk is available here. And, if you are interested in the talk’s content, the slides are also available here.
