Read the chapter: chapter XVIII Steganography and Steganalysis
Provide an overview of the article:
The article aims at creating a more hands on approach towards learning computer security. It covers key
security principles and approaches that are important in modern world. The article focuses mainly on corporate
world and how to better secure businesses from security threats. Chapter 18 highlights the importance of
steganography and steganalysis in digital world. It defines the basics of steganography as a covered writing. In
essence, it is defined as any process that aims at concealing information or hiding data being sent. A brief
history of steganography is given and its application in modern world. Finally, steganalysis is briefly discussed
and how it is used to analyze the presence of hidden data.
Describe LSB Steganography:
LSB Steganography is a technique used in hiding messages whereby the messages are hidden inside an image.
This is achieved by replacing each pixel’s least significant bit with messages bits that are supposed to be
hidden. To be able to hide messages with this type of steganography, the following steps are followed:
–
Encoding the message into binary codes
–
Determining the length of encoded message
–
Adding the message and its length to the Pixel’s LSBs
To decode
–
Decode its length from the starting bits
–
Decode the pixels to determine the hidden message
It is often difficult and time consuming to detect steganography. What are some clues for a forensic
analyst to discover the presence of steganography? (might need some additional research / Google
searchers)
The messages in steganography are hidden from unauthorized users, therefore, it become difficult to detect it.
As a forensic analyst to detect steganography would require careful physical examination. These examinations
can entail the use of ultra violet light, magnification and chemicals for a physical document. For digital files,

steganalysis can come in handy. It entails the detection of steganographically encoded files. For a digital image,
one compare the suspected image with the original one. Discrepancy in file sizes or pixels can be one of the
clue.

Describe what this website does:
Spam mimic websites offers a tool that allows users to encrypt their messages, therefore, making it hard for it to
be intercepted. Additionally, it allows the creation of spam messages from short messages.
