Reverse engineering (RE) is the process of taking something apart to see how it works and making a product that functions, in whole or part, like the original product, or as an intermediate step to an improvement on the original product. It is an attempt to recover as much of the “top level specification”1 of a product as possible, and understand how and why a product works. Other related concepts to reverse engineering are reverse modeling and image reconstruction. In this chapter will be a discussion of the general subject of reverse engineering, case examples, and a list of resources.
