Module Overview

With the tremendous growth of the Internet and computer technologies, and the wide usage of multimedia content such as audio, image and video data, the protection and authentication of multimedia content is becoming increasingly important to industry and government sectors, as well as for individual personal usage. Moreover, recent terrorist events such as 9/11 and London bombings further highlight the necessity of information security technologies that can be applied to detect covert communication, such as steganography (data hiding) and cryptography, as well as deploying multimodal biometric techniques that can be used to accurately identify faked passports at airports and border checkpoints. Protection of ownership and authentication of multimedia contents and documents are also attracted significant attention in the digital arena through the application of digital watermarking and digital rights management technologies.

This module will provide an introductory background to various digital security technologies currently used in different applications for multimedia content and documents. The knowledge gained in this module will also serve as a pre-requisite for students to attend the more advanced modules in Security Technologies and Applications.
Module Aims

The main aim of this module is to provide students with a comprehensive understanding of the fundamentals of multimedia security technologies for multimedia content currently available in the digital arena. The module will equip students with a critical awareness of current technologies including digital steganography and its counter-measure, steganalysis, watermarking and authentication, cryptographic techniques and biometric identification. Through lab sessions students will be able to apply their theoretical understanding in developing and evaluating a digital watermarking system prototype.     

Learning Outcomes
  • Demonstrate a critical awareness of digital steganography and steganalysis techniques for images and text documents
  • Contrast the different types of digital watermarking systems for copyright protection and authentication applications
  • Describe and account for the differences in multimodal biometrics systems
Demonstrate a systematic understanding of cryptographic algorithms and their usage in industrial applications
