This trend is continuing and will for the foreseeable future. While an enormous amount of text, data, speech, music, image and video is easily exchanged through the Internet and other communication channels, some serious security issues have arisen: in particular, information assurance (authentication, integrity and access control), which has caught the attention of people, societies and governments worldwide.
Since the middle of the 1990s, digital watermarking has been proposed as an enabling technology for solving security problems in multimedia applications. Digital watermarks have now been used in applications including broadcast monitoring, movie fingerprinting, digital rights management, secure data systems, secure data exchange, video indexing and retrieval, and image authentication, to name a few. In some of these applications, data hiding and cryptographic techniques complement each other to achieve the goal. It is expected that this approach will mature and will play a significant role in future multimedia applications.
As a reflection of this trend, several international workshops and special sessions in conventional conferences and workshops have been devoted to the field of digital watermarking and data hiding. More and more papers have been published in this field. This new journal, LNCS Transactions on Data Hiding and Multimedia Security, aims at publication of original and archival research in this field.
