摘要: Information Hiding: Steganography and Watermarking - Attacks Countermeasures deals with information hiding. With the proliferation of multimedia on Internet, hiding addresses two areas concern: privacy from surveillance (steganography) protection intellectual property (digital watermarking). (literally, covered writing) explores methods to hide existence hidden messages. These include invisible ink, microdot, digital signature, covert channel, spread spectrum communication. Digital watermarks represent a commercial application steganography. Watermarks can be used track copyright ownership electronic media. In this volume, authors focus techniques for in They analyze uncover their limitations. limitations are employed devise attacks against information. The goal these is expose secret message or render watermark unusable. assessing attacks, countermeasures developed assist protecting watermarking systems. Understanding current will lead us build more robust that survive various manipulation attacks. placed public's reach owners such need protect themselves theft false representation. Systems uncovering recover seemingly destroyed useful law enforcement authorities computer forensics traffic analysis. presents authors' research contributions three fundamental respect image-based steganography watermarking: analysis data techniques, information, watermarks. e suitable secondary text graduate level course, as reference researchers practitioners industry.
