While enormous digital multimedia data nowadays mostly enrich our everyday life, cyber terrorists and cyber criminals may use the data to conduct stealthy communication by using steganography, or alter the truth and make fraudulent illusions by forgery manipulation. To protect national security and public safety, multimedia forensics has emerged and developed in a rapid fashion; however, it still falls short of efficient and effective digital forensics algorithms and/or systems. Particularly, advanced steganography and advance forgery on multimedia data with combined attacks have severely impeded the progress in multimedia forensics.
