HIDDEN IN PLAIN SIGHT CT SOFTWARE

The first known use of steganography was in ancient Greece where messages were carved in wax tablets that were then covered with more wax.

These software engineers are the front lines in detecting illegal behavior and protecting our country. Regardless, software engineers must be able to detect very subtle changes in documents and images in order to detect hidden messages. They also try to detect information hidden by using steganography this can be thought of as cyber law enforcement. Software engineers use steganography to hide information in messages. Steganography is used by countries and their governments, as well as terrorists. This is one of the coolest topics that you may have never heard of which may have large impacts on your life. In this lesson, you will be introduced to the concept of steganography, which is the art and science of hiding information in plain sight. The teacher should have a working knowledge of the engineering design process. Lesson Assessment Answers (pdf) Visit [ to print or download. Describe positive and negative uses of steganography.Compare and contrast several different methods of steganography.These software engineers are on the front lines in detecting illegal behavior that is planned and communicated via steganography.Īfter this lesson, students should be able to: Software engineers, both those who hide messages and those who attempt to detect messages, use the design process to identify methods for hiding information and detecting the very subtle document and image changes that indicate the presence of hidden messages. More recently, terrorists use steganography to hide messages from law enforcement. For a centuries, individuals and governments have delivered messages to interested parties secretly using steganography. The process is driven by the concept of steganography, which may be new to students and potentially intriguing. Students identify a problem, develop solutions, select and implement a possible solution, test the solution and redesign as needed to meet requirements.

Students obtain practice with a portion of the design process that may be less exciting, but is just as important as the other steps in the process.Īlong with its associated activity, the lesson is designed to provide students with practice in implementing the engineering design process.

In computer science, a thorough design phase makes program implementation much easier and more effective. These are the critical first steps in the engineering design process, often overlooked by students who want to get to the 'doing' phases-designing, building and testing. Through this lesson, students experience a portion of the engineering design process as they research steganography and steganographic methods identify problems, criteria and constraints brainstorm possible solutions and generate ideas. Steganography can be characterized as security through obscurity. Steganography is the science and art of hiding messages in plain sight so only the sender and intended recipient know the existence of a message.
