eHealth 2008, the First International Conference on Electronic healthcare for the twenty-first century, was held in City University, London, during September 8-9, 2008. The conference was organized as a meeting point for telecare product vendors, policy makers, government ministers, academics, clinicians and all those involved in electronic and mobile health, to examine and to share ideas contributing to the - vancement of electronic healthcare into the twenty-first century. The conference had a huge success with a large number of paper submissions. Ninety-seven papers were submitted, of which 32 were selected for presentation. Each paper was carefully reviewed blindly by a minimum of three referees from the resp- tive field. A special thanks should go to the Technical Program Committee for their hard and efficient work in the review process. In addition to the submitted contributions, the conference included a business pres- tation track with 12 invited talks by key people in the world of eHealth. The business presentation track was chaired by Sir Jonathan Michael (Deputy Director, BT Health). The success of this conference is to be credited to the contribution of many people.

ISDF 2009, the First International Conference on Information Security and Digital Forensics, was held at City University London during September 7-8, 2009. The c- ference was organized as a meeting point for leading national and international - perts of information security and digital forensics. The conference was rewarding in many ways; ISDF 2009 was an exciting and vibrant event, with 4 keynote talks, 25 invited talks and 18 full-paper presentations and those attending had the opportunity to meet and talk with many distinguished people who are responsible for shaping the area of information security. This conference was organized as part of two major research projects funded by the UK Engineering and Physical Sciences Research Council in the areas of Security and Digital Forensics. I would like to thank all the people who contributed to the technical program. The most apparent of these are the Indian delegates who all accepted our invite to give presentations at this conference. Less apparent perhaps is the terrific work of the members of the Technical Program Committee, especially in reviewing the papers, which is a critical and time-consuming task. I would like to thank Raj Rajarajan (City University London) for making the idea of the ISDF 2009 conference a reality with his hard work. Last but not least, I would like to thank all the authors who submitted papers, making the conference possible, and the authors of accepted papers for their cooperation. Dasun Weerasinghe

This book investigates the security and privacy issues in mobile healthcare management and develops solutions based on Mobile Web services and XML security technologies. Web services can be extended to develop services for the applications in mobile hand-held devices that are connected to a mobile network. Transferring healthcare services to electronic and mobile environment is one of the emerging research areas in healthcare as solutions to the present overstretched and under budgeted healthcare services. This approach will transfer patient medical records and services on wired and over the air techniques between patients and healthcare services. So patients and healthcare service providers have remote access to medical records and medical services over the Internet or mobile network. Mobile healthcare environment transfer patient life sensitive medical records between different actors in the environment. There are a number of possible external security attacks on the system during the data storage and transmission. Therefore, protecting the mobile healthcare Web services environment from security and privacy attacks is one of the emerging research areas.
