Since the mid 1990s, data hiding has been proposed as an enabling technology for securing multimedia communication, and is now used in various applications including broadcast monitoring, movie fingerprinting, steganography, video indexing and retrieval, and image authentication. Data hiding and cryptographic techniques are often combined to complement each other, thus triggering the development of a new research field in multimedia security. Two related disciplines, steganalysis and data forensics, are also increasingly attracting researchers and forming another new research field in multimedia security. This journal, LNCS Transactions on Data Hiding and Multimedia Security, aims to be a forum for all researchers in these emerging fields, publishing both original and archival research results.

This inaugural issue contains five papers dealing with a wide range of topics related to multimedia security. The first paper deals with evaluation criteria for the performance of audio watermarking algorithms. The second provides a survey of problems related to watermark security. The third discusses practical implementations of zero-knowledge watermark detectors and proposes efficient solutions for correlation-based detectors. The fourth introduces the concept of Personal Entertainment Domains (PED) in Digital Rights Management (DRM) schemes. The fifth reports on the use of fusion techniques to improve the detection accuracy of steganalysis.

Negli ultimi decenni il rapido sviluppo delle tecnologie IT ha influito in maniera determinante nella vita dell'uomo, trasformando, spesso inconsapevolmente il suo lavoro, le sue abitudini, il suo modo di interagire con il mondo che lo circonda. Il fenomeno della "globalizzazione" dei mercati e solo una delle trasformazioni che l'intero pianeta sta attraversando. Anche se i vantaggi derivanti dall'utilizzo delle moderne tecnologie di comunicazione ci facilitano nel lavoro e nella attivita ludiche e personali, molte sono le perplessita e i dubbi che attanagliano tutti coloro che le utilizzano. Se l'Information Technology rappresenta il "combustibile" indispensabile per la sopravvivenza delle aziende e delle attivita dell'uomo, nel contempo puo generare problematicita di grande rilievo. Il testo tratta alcune delle problematiche che destano preoccupazioni rilevanti nel mondo intero come il consumo energetico dei sistemi informatici (incontrollabili e inquinanti), il problema della garanzia della privacy e dell'integrita dei dati su Internet, l'utilizzo della rete Internet come strumento di controllo delle masse, la possibile sparizione degli attuali sistemi operativi che potranno essere sostituiti dal sistema operativo Web Operating System."

It is our pleasure to present in this volume the proceedings of the 7th Inter- tional Workshopon InformationHiding (IH 2005), held in Barcelona, Catalonia, Spain, during June 6-8, 2005. The workshop was organized by the Department of Computer Science and Multimedia, Universitat Oberta de Catalunya (UOC). Continuing the tradition of previous workshops, we sought a balanced p- gram, containing talks on various aspects of data hiding, anonymous commu- cation, steganalysis, and watermarking.Although the protection of digital int- lectual property has up to now motivated most of our research, there are many other upcoming ?elds of application. We were delighted to see that this year's workshop presented numerous new and unconventional approaches to infor- tion hiding. The selection of the program was a very challenging task. In total, we - ceived 90 submissions from 21 countries. At this point we want to thank all authors who submitted their latest work to IH 2005-and thus assured that the Information Hiding Workshop continues to be the top forum of our community.

The10thintheseriesofIMAConferencesonCryptographyandCodingwasheld at the RoyalAgricultural College, Cirencester, during 19 21 December 2005. As usual, the venue provided a relaxed and informal atmosphere for attendees to discuss work and listen to the collection of talks. The program consisted of four invited talks and 26 contributed talks. The invitedtalkswheregivenbyTuviEtzion, UeliMaurer, AlfredMenezesandAmin Shokrollahi, and three of these invited talks appear as papers in this volume. Special thanks must go to these four speakers as they helped to set the tone, by coveringall the areasthe meeting aimed to cover, from cryptographythrough to coding. In addition the best speakers are often the hardest to persuade to come to a meeting, as they are usually the most busy. We therefore feel privileged to have had a meeting with four such distinguished speakers. The contributed talks were selected from 94 submissions. This is nearly twice thenumberofsubmissionsforthepreviousmeetingin2003.Thisisanindication of the strength of the subject and the interest in the IMA series of meetings as a venue to present new work. The contributed talks ranged over a wide number of areas, including information theory, coding theory, number theory and as- metric and symmetric cryptography. Subtopics included a number of current hot topics, such as algebraic cryptanalysis and cryptographic systems based on bilinear pairings. Assembling the conference program and these proceedings required the help of a large number of individuals. I would like to thank them all here."
