   Reverse engineering is one of the useful procedures of discovering the technological principles of a human made machines, object or system through observing its structure, function and operation. Usually in this process a mechanical device, electronic component, or software program is involve for the analysis of its workings in detail to be used in maintenance, or to try to prepare a new gadget or program that perform the same thing without using the real one .
   The origin of Reverse engineering belongs to the analysis of hardware for commercial or military benefits. The usage of this procedure is to infer the design decisions from end products with little or no additional knowledge about the process involved in the original manufacture. The same method is subsequently being researched for application to legacy software systems, not for industrial or defense ends, but rather to changed incorrect, incomplete, or otherwise unavailable documentation.
   The phrase reverse engineering as applied to software describes as different things to different people, prompting Chikofsky and Cross to write a paper finding the different usage researching of different products and defining taxonomy. From their paper, they said, "Reverse engineering is the complete procedure of analyzing a subject system in order to prepare representations of the system at a top level of abstraction. According to this project the output of the implementation phase is reverse-engineered back to the analysis stage, in an inversion of the traditional waterfall model. Reverse engineering is a procedure of observation only: the software system under analysis is not improved or replaced.
