Breakthrough software protection techniques for fighting piracy, tampering, and malicious reverse engineering * * Everything software and content developers need to know to protect their intellectual property - including pioneering techniques available in no other book * Includes extensive code examples, supported with a new model designed to help readers classify, compare, and choose the right algorithms for their applications. * By three of the world's most respected software security researchers. Software companies and content providers spend millions of dollars every year fighting piracy, tampering, and malicious reverse engineering. Microsoft alone has spent over $400 million on these challenges. In this book, three of the world's leading software security experts present ground-breaking techniques for protecting their valuable assets against intellectual property theft. The authors' comprehensive new approach, called 'surreptitious software,' brings together techniques not only from computer security, but also from many other areas of computer science, including cryptography, steganography, watermarking, software metrics, reverse engineering, and compiler optimization. Readers will learn how to implement software protection schemes ranging from birthmarking and fingerprinting to code obfuscation. The authors even cover the use of software to defend against hardware exploits. Drawing on these techniques, readers can address the full spectrum of IP protection problems, from tracing software pirates to tamper-proofing software against the removal of license checks - all without adding any more computational overhead than absolutely necessary. Surreptitious Software includes extensive code examples, as well as a new model for classifying and comparing algorithms - everything readers need to choose the right approaches, and successfully implement them.

Obfuscation, Watermarking, and Tamperproofing for Software Protection

Surreptitious Software

“This book gives thorough, scholarly coverage of an area of growing importance in computer security and is a ‘must have’ for every researcher, student, and practicing professional in software protection.” —Mikhail Atallah, Distinguished Professor of Computer Science at Purdue University Theory, Techniques, and Tools for Fighting Software Piracy, Tampering, and Malicious Reverse Engineering 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 the first authoritative, 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 trace software 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

This volume constitutes the refereed post-proceedings of the 8th International Workshop on Information Hiding held in Alexandria, Virginia, in July 2006. Twenty-five carefully reviewed full papers are organized into topical sections covering watermarking, information hiding and networking, data hiding in unusual content, fundamentals, software protection, steganalysis, steganography, and subliminal channels.
