SURREPTITIOUS SOFTWARE

The last decade has seen significant progress in the development of techniques for resisting software piracy and tampering. These techniques are indispensable for software developers seeking to protect vital intellectual property. 'Surreptitious Software' is comprehensive resource for researchers, developers, and students who want to understand these approaches, the level of security they afford, and the performance penalty they incur. Christian Collberg and Jasvir Nagra bring together techniques drawn from related areas of computer science, including cryptography, steganography, watermarking, software metrics, reverse engineering, and compiler optimization. Using extensive sample code, they show readers how to implement protection schemes ranging from code obfuscation and software fingerprinting to tamperproofing and birthmarking, and discuss the theoretical and practical limitations of these techniques.Coverage includes: Mastering techniques that both attackers and defenders use to analyze programs; Using code obfuscation to make software harder to analyze and understand; Fingerprinting software to identify its author and to tracesoftware pirates; Tamperproofing software using guards that detect and respond to illegal modifications of code and data; Strengthening content protection through dynamic watermarking and dynamic obfuscation; Detecting code theft via software similarity analysis and birthmarking algorithms; Using hardware techniques to defend software and media against piracy and tampering; Detecting software tampering in distributed system; Understanding the theoretical limits of code obfuscation.
