As rapid and tremendous progress in information technology is constantly being made, and, while an enormous amount of media such as text, audio, speech, music, image and video can be easily exchanged through the Internet and other communication networks, information security issues such as copyright protection, digital right management, integrity verification, authentication, and access control have become exceptionally acute. As a result, the subject of data hiding for information security and forensics has been taken as one of the top research and development agendas for researchers, organisations and governments worldwide. In addition, data hiding techniques have also found applications in the areas of covert communication, image/video indexing, medical image archiving and exchange, transmission error recovery and concealment, image captioning, audio in video for language translation, etc.
