July 15, 2020 @ 12:00pm - 1:00pm CDTFree
A common frustration in the investigative process is the authentication of digital images. It is difficult to definitively conclude that an image is legitimate for the purpose of evidence collection, subject identification, or timeline reconstruction. This presentation will provide some insight into the tools and techniques used to detect image forgery and alterations beyond mere observation by examining embedded noise, wave-forms, and lossy-format error levels. It will also cover the concept of camera ballistics used to match images to the camera used to capture it.
