If the messagemethod is not determined after an allotted amount of time, the original group should shareexplain its method of message encoding.Once their messages are hidden, classmates attempt to decipher them.

Steganography Examples For Kids Software Engineers PerformThis means that software engineers perform analyses that create and identify these hidden messages. In examples dealing with terrorism communication, their success or failure to identify messages can determine the outcome of an attack and citizen safety. Computers are useful for a variety of purposes, such as running simulations to test different ways of solving a problem or to see which one is most efficient or economical; and in making a persuasive presentation to a client about how a given design will meet his or her needs. Steganography has been used historically to convey secret messages in plain sight. The first known use of steganography was in ancient Greece, and it has been used in many wars since. In recent years, terrorists have used steganography to pass information and help plot attacks. Thus, computer software engineers are on the front lines for detecting messages hidden using steganography. In Figure 1, the innocuous looking trees are hiding the cat, shown in Figure 2. The hidden image is revealed by removing all but the two least significant bits of each color component and then performing normalization on the resulting image. It is an extension of what is taught in the AP curriculum and requires knowledge of Java programming. Using the resources provided in the attachments, students create an image with information hidden in it using steganography. To accomplish this task, they must follow the engineering design process, shown in Figure 3. Steganography Examples For Kids How To Modify TheThey must identify the problem and its constraints, create ideas about how to modify the image, select and implement the solution, test the solution (done by classmates to see if they can discover the message), and finally refine the solution to better solve the problem. The image, available software, and their knowledge of steganography are the constraints. The implementation is done using the Java PictureEdit class to modify the image in some fashion determined by the student. Place these files on each computer along with the Java editor of your choice. ![]() Picture Edit Zip contains: PictureEdit.java and Picture Edit API documentation. Using the API documentation, you can see how the PictureEdit class is created and how you can modify images using it. Using the API documentation (from whatever Java editor you are using), students can see how the PictureEdit class is created and how they can modify images using it.
