(50 minutes).
This talk focuses on using Python to acquire LIVE open-source intelligence (OSINT) from tweets and the associated images, videos, and translated emojis from geographically bounded areas anywhere in the world. This method delivers a plethora of information (tweets, images, videos, emojis, friends, followers, and detailed mapping of movement) within a specific time/space continuum, including chronolocation data. Twitter routinely removes tweets and images from their platform based on policy violations and other influences. By acquiring them “at the moment they are tweeted” provides timely access to live events, as well as the ability to preserve future redacted information. Our ability to generate alerts of aberrant behaviors through the lens of those on the scene has never been more important. The lecture and demonstration will include real examples of collections and mapping from war zones, natural disasters, social unrest, and criminal activity.
