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."

This volume contains the proceedings of the 8th International Information - curity Conference (ISC 2005), which took place in Singapore, from 20th to 23rd September 2005. ISC 2005 brought together individuals from academia and - dustry involvedin manyresearchdisciplines of information security to foster the exchange of ideas. During recent years this conference has tried to place special emphasis on the practical aspects of information security, and since it passed from being an international workshop to being an international conference in 2001, it has become one of the most relevant forums at which researchers meet and discuss emerging security challenges and solutions. Advised by the ISC Steering Committee, and in order to provide students with more opportunities for publication, ISC 2005 accepted extra student papers - sides the regular papers. The initiative was very well accepted by the young sector of the scienti?c community, and we hope that the success of this idea will remainfornextISCevents. AnotherimportantfactorforthesuccessofISC2005 was that selected papers in the proceedings will be invited for submission to a special issue of the InternationalJournalof InformationSecurity. The result was an incredible response to the call for papers; we received 271 submissions, the highest since ISC events started. It goes without saying that the paper selection process was more competitive and di?cult than ever before - only 33 regular papers were accepted, plus 5 student papers for a special student session.

We are delighted to welcome the attendees of the Fourth International Wo- shop on Digital Watermarking (IWDW). Watermarking continues to generate strong academic interest. Commercialization of the technology is proceeding at a steadypace. We haveseen watermarkingadoptedfor DVD audio.Fingerpri- ing technology was successfully used to determine the source of pirated video material. Furthermore, a number of companies are using watermarking as an enabling technology for broadcast monitoring services. Watermarking of digital cinema contentis anticipated. Future applications may also come from areas- related to digital rights management. For example, the use of watermarking to enhance legacy broadcast and communication systems is now being considered. IWDW 2005 o?ers an opportunity to re?ect upon the state of the art in digital watermarking as well as discuss directions for future research and applications. This year we accepted 31 papers from 74 submissions. This 42% acceptance rate indicates our commitment to ensuring a very high quality conference. We thankthemembersoftheTechnicalProgramCommitteeformakingthispossible by their timely and insightful reviews. Thanks to their hard work this is the ?rst IWDW at which the ?nal proceedings are available to the participants at the time of the workshop as a Springer LNCS publication.

This book constitutes the refereed proceedings of the 11th Australasian Conference on Information Security and Privacy, ACISP 2006, held in Melbourne, Australia, July 2006.

Althoughcryptographyandsecuritytechniqueshavebeenaroundfor quitesome time, emerging technologies such as ubiquitous computing and ambient intel- gence that exploit increasingly interconnected networks, mobility and pers- alization put new requirements on security with respect to data management. As data is accessible anytime anywhere, according to these new concepts, it - comes much easier to get unauthorized data access. Furthermore, it becomes simpler to collect, store, and search personal information and endanger people's privacy. Therefore, researchin the area of secure data management is of growing importance, attracting the attention of both the data management and security researchcommunities.Theinterestingproblemsrangefromtraditionalones, such as access control (with all variations, like dynamic, context-aware, role-based), database security (e.g., e?cient database encryption schemes, search over - crypted data, etc.), and privacy-preserving data mining to controlled sharing of data. In addition to the aforementioned subject, this year we also called for - pers devoted to secure data management in healthcare as a domain where data security and privacy issues are traditionally important. The call for papers - tracted 38 papers both from universities and industry. The ProgramCommittee selected 16 research papers for presentation at the workshop. These papers are also collected in this volume which we hope will serve you as a useful research and reference material.
