Beschreibung
Conventional cryptography (enciphering and deciphering messages) is like shipping a safe in an armored car with a regiment of soldiers around it. Everyone knows that there's something secret inside. This book describes steganography, the science of hiding or disguising information so it can only be found by someone who knows where to look. This new edition of our best-selling book on cryptography and information hiding delineates a number of different methods to hide and therefore protect information in all types of digital media files. These methods include encryption, compression, data embedding and watermarking, data mimicry, and scrambling. During the last 5 years, the continued advancement and exponential increase of computer processing power have enhanced the efficacy and scope of electronic espionage and content appropriation. Therefore, this edition has amended and expanded outdated sections in accordance with new dangers. von Wayner, Peter
