his week's reading gives you basic technical information about passwords and encryption, and how to recover data protected by these mechanisms. There is also a section on Steganography, which literally translated means "covered writing." When some people think of steganography, or "stego," they think of documents or other data files being hidden in other file types (usually image/picture files). Interestingly, the use of stego goes much farther back than the use of computers.  Like cryptology, steganography is used to hide something in something else. So, even though a code breaker can detect the hidden code, they may not be aware that the code actually contains a different message. Cryptography scrambles a message so that it is unreadable, but still visible, while stego camouflages data to hide it or make it undetectable. This course is not meant to teach you about the technical details of encryption or passwords or steganography (entire books are written on each of those subjects), but rather to help you understand their place in the criminal justice process.

Does a warrant give you the authority to break passwords protecting information or to decipher encrypted data? This is a very important question. As many of you have discussed, it is important to make sure you know the limits of your warrant.  But while you are conducting a search with a properly executed warrant, you may come across other information that is not included in your scope but is still evidence of a crime. For example, imagine you are searching a hard drive for information related to a fraud scheme. While you are looking through the files you come across a picture that is obviously child porn, but you do not have child porn addressed in any way by your warrant. What do you do? The proper response is to stop the search and obtain another warrant for evidence related to child pornography. The same thing applies to discovering encrypted data. In your affidavit you should explain that criminals sometimes encrypt files that contain evidence. Some may even use stego techniques to hide other files.

This week I would like you to do some research on encryption and steganography.  

1.            List five (5) examples each of how steganography and encryption or cryptology were used BEFORE the advent of computers. (REMEMBER it has to be 5 EXAMPLES each of steganography and encryption)
2.            Discuss how steganography or encryption could be used legitimately, and 
3.            Why this could cause you a problem as a computer forensic examiner.

Also Include two different reply comment to the over all questions. Must be half a page for each comments.

All APA citations must be formatted perfectly. Also, all answers must be answered in a full paragragh. Must be half a page answers on each questions. and must be discussed thoroughly. you can include any outside source too. I have provided the chapter 7 text so as to help answer the questions. thanks
