We identify three types of attack on the intellectual property contained in software and three corresponding technical defenses.A defense against reverse engineering is obfuscation, a process that renders software unintelligible but still functional. A defense against software piracy is watermarking, a process that makes it possible to determine the origin of software. A defense against tampering is tamper-proofing, so that unauthorized modifications to software will result in nonfunctional code. We briefly survey the available technology for each type of defense.What is water marking?• Originally used to identify paper quality• Anti-counterfeiting of paper money• Extended to other forms of hidden information.Definitions:• Work: specific song, video, image, text, etc.• Watermarking: practice of imperceptibly altering a work to embed a message about that work.WATER MARKING GOALS:– verify the owner of a digital image– detect forgeries of an original image– identify illegal copies of the image–Prevent unauthorized distribution.
