Zero Watermarking Using Sectional Obfuscation Scheme and Stealthy Code Obfuscation Technique

Abstract: Stealing of Watermarks is a fashionable trend in the scientific field ,the most common medium for exchange of information used is the plain text which suffers from tampering attacks. There are very limited techniques available for plain text watermarking and authentication. The traditionally used methods are obfuscation and watermarking. In order to overcome such limitation the concept of code obfuscation and zero watermarking are combined. The use of opaque predicates as one of the building blocks of obfuscating transformation conceals the control flow of the program in the protection of intellectual property. By this the ownership of the software products can be proved, which increases the security level of the software to a greater extend.

Keywords: obfuscation, software security, zero water marking, authentication.
