Learning Outcomes
At the end of this course, students should be able to:
1. discuss secret writing and different methods and tools used for each;
2. identify why steganography is important, and how it is different from cryptography and
encryption;
3. describe the uses and applications of steganography, and how to use steganography
methods and work with any of the steganography types and techniques;
4. practice the different steganography techniques for encrypting the data and use data
hiding methods, techniques and access methods;
5. develop the information-hiding systems, steganography algorithm and security of a
steganographic algorithm;
6. analyse how to detect steganography, finding images, and verifying hidden content; and
7. organise practical experimentation of data hiding tools, investigation techniques and the
latest countermeasures.
