Steganography is the art and science of sending covert messages such that the existence and nature of such a message is only known by the sender and intended recipient.
Steganography has been practised for thousands of years, but in the last two decades steganography has been introduced to digital media. Digital steganography techniques typically focus on hiding messages inside image and audio files; in comparison, the amount of research into other digital media formats (such as video) is substantially limited.
In this talk we will discuss the history of steganography and the categories of steganographic technique before briefly discussing image and audio steganography and how to build such tools. The main body of our talk will focus on how video files are coded and the steganographic techniques that can be used to hide messages inside video files.
The principles discussed in this talk will be illustrated with live demos.
This lecture will take place at 10:00 on Monday, 22nd April 2013 in Mappin, LT02. This lecture is being pitched specifically for:
