Robust Detection of Copy-Move Forgery Based on Wavelet Decomposition and Firefly Algorithm

Abstract

Abstract Nowadays, the whole world is covered with the revolution of digital information so that digital data are easy to transfer, access and process. Modern image processing tools are used to create forged images; by using these tools, forgers introduced forged region in the original image to spread the rumor in the public. Now there is a challenge for the forensic department to prove the authenticity of the original image. So there is required a new efficient copy-move tamper detection method. To fulfill this requirement, a new computational efficient method for copy-move forgery detection using firefly algorithm is proposed.
