Programming security is a paramount concern in IT industry because of its immense monetary misfortunes. Programming is inclined to different security assaults, for example, Software piracy. In this proposal, program security assurance through code Obfuscation, a technique which opposes reverse engineering attacks. In this paper, different sets of criteria are depicted to gauge viability of code obfuscation, for example, intensity: trouble for human to comprehend code, imperviousness to computerized piracy. A large portion of the current obscurity procedures and plans fulfil just a couple of these criteria. In this paper, it shows that the novel code obfuscation plan created for securing exclusive code. A software framework for providing software security using Metric based Code Obfuscation Techniques named as M-COT is designed to propose which will maximize the objectives. The essential thought is to change unique code to obfuscated codes which will concede more state space. This is attained by developing obfuscated non inconsequential code clones for intelligent code parts exhibit in unique code. These code clones that are connected utilizing element predicate variables to present legitimate control flows. The performance of the system is observed by experimentation on a couple of projects (for example, scientific calculator code, searching) to assess our plan. The demonstration made that product unpredictability nature of obfuscated code is higher than that of unique code and comparing to single execution Despite of the fact that the proposal builds the improvement of obfuscated code (because of development of non-inconsequential code clones for legitimate code parts).
