Introductory description

In this module, you will learn about the scientific techniques used to collect probative facts from digital data often in relation to cyberphysical crime.

Module aims

The module will focus on a subfield of digital forensics that involves analysing image and video data for forensic purposes. This subfield (digital image forensics) is getting increasingly important since digital cameras and sophisticated photo editing softwares have become commonplace. Advanced machine learning methods are now capable of generating fake images and videos that can easily fool humans. Image forensic experts develop and use computational techniques to identify photo forgery, detect image sources and collect crime-related evidences from image data.

Outline syllabus

This is an indicative module outline only to give an indication of the sort of topics that may be covered. Actual sessions held may differ.

The module will deal with core concepts and enabling methodologies in multimedia-based digital
forensics. It will also examine current applications, and address theoretical and practical
challenges. More specifically the syllabus will cover:

Learning outcomes

By the end of the module, students should be able to:

Research element

The 'Sensor based forensics' section in the syllabus is based on recent research advances on this topic. The students will be reading from research papers instead of textbooks. They will also implement the techniques described in the research paper.
