Developing a secure healthcare information network on the Internet.
Healthcare professionals across the country are using the Internet for a variety of activities, including the transmission of medical record data via e-mail. The transmission of confidential information, however, is a serious concern of healthcare consumers, providers, and payers alike. At Indiana University School of Medicine, security on the Internet is no longer a concern. The Internet is, in fact, the heart of a healthcare information network currently in development for the Indianapolis area. A complex set of encryption/decryption algorithms and user identifier and private passwords currently in development should greatly reduce the risk of security breach on the network.

Legal issues: office management practices.
Student health records, whether paper or electronic, are restricted and protected to a greater degree than are educational records. Some school health office software is designed to provide greater data protection than is possible in paper records. However, unless basic district and health office practices are established to prevent access to or corruption of electronic health data, technological safeguards will be useless. This article describes school and health office policies and practices that are necessary for the integrity, confidentiality, and security of student health information.

Integrating the lightweight authentication protocol (LAP) with access control mechanisms in wireless health care information systems.
Health information networks are expected to support information exchange that is authentic, accurate, private and available when, where and to whom is needed. With the increase of the shared medical information and resources in healthcare wireless information systems, unauthorized access to the information by illegal users also increases. The security of the transmitted information is a vital issue. In this paper, we report on the development of the Lightweight Authentication Protocol (LAP), which makes a mobile and distributed system more secure and flexible and we implement it in a Health Care Environment where the clinicians use mobile and wireless devices like PDAs. We also provide an indicative example of integrating the LAP with access control mechanisms. Context-based Team Access Control (C-TMAC) model is used in this example, since it provides great flexibility on user-permissions management in collaborative healthcare environments. LAP is indeed capable to support efficiently the advanced authorization procedures of such demanding active security models.

ARTEMIS: towards a secure interoperability infrastructure for healthcare information systems.
The ARTEMIS project is developing a semantic web service based P2P interoperability infrastructure for healthcare information systems. The strict legislative framework in which these systems are deployed means that the interoperability of security and privacy mechanisms is an important requirement in supporting communication of electronic healthcare records across organisation boundaries. In ARTEMIS, healthcare providers define semantically annotated security and privacy policies for web services based on organisational requirements. The ARTEMIS mediator uses these semantic web service descriptions to broker between organisational policies by reasoning over security and clinical concept ontologies.

Privacy-preserving framework for genomic computations via multi-key homomorphic encryption.
MOTIVATION: The affordability of genome sequencing and the widespread availability of genomic data have opened up new medical possibilities. Nevertheless, they also raise significant concerns regarding privacy due to the sensitive information they encompass. These privacy implications act as barriers to medical research and data availability. Researchers have proposed privacy-preserving techniques to address this, with cryptography-based methods showing the most promise. However, existing cryptography-based designs lack (i) interoperability, (ii) scalability, (iii) a high degree of privacy (i.e. compromise one to have the other), or (iv) multiparty analyses support (as most existing schemes process genomic information of each party individually). Overcoming these limitations is essential to unlocking the full potential of genomic data while ensuring privacy and data utility. Further research and development are needed to advance privacy-preserving techniques in genomics, focusing on achieving interoperability and scalability, preserving data utility, and enabling secure multiparty computation. RESULTS: This study aims to overcome the limitations of current cryptography-based techniques by employing a multi-key homomorphic encryption scheme. By utilizing this scheme, we have developed a comprehensive protocol capable of conducting diverse genomic analyses. Our protocol facilitates interoperability among individual genome processing and enables multiparty tests, analyses of genomic databases, and operations involving multiple databases. Consequently, our approach represents an innovative advancement in secure genomic data processing, offering enhanced protection and privacy measures.

A joint signal processing and cryptographic approach to multimedia encryption.
In recent years, there has been an increasing trend for multimedia applications to use delegate service providers for content distribution, archiving, search, and retrieval. These delegate services have brought new challenges to the protection of multimedia content confidentiality. This paper discusses the importance and feasibility of applying a joint signal processing and cryptographic approach to multimedia encryption, in order to address the access control issues unique to multimedia applications. We propose two atomic encryption operations that can preserve standard compliance and are friendly to delegate processing. Quantitative analysis for these operations is presented to demonstrate that a good tradeoff can be made between security and bitrate overhead. In assisting the design and evaluation of media security systems, we also propose a set of multimedia-oriented security scores to quantify the security against approximation attacks and to complement the existing notion of generic data security. Using video as an example, we present a systematic study on how to strategically integrate different atomic operations to build a video encryption system. The resulting system can provide superior performance over both generic encryption and its simple adaptation to video in terms of a joint consideration of security, bitrate overhead, and friendliness to delegate processing.

Image file interoperability for data protection, communication and trans-system connectivity.
DICOM (Digital Imaging and Communication in Medicine) is a set of international imaging standards developed for medicine and extended to incorporate other professions. These standards encompass primary digital and secondary capture images made for dental diagnostic procedures. The standards provide a basis of interoperability for digital system outputs, providing portability and reducing the danger of obsolescence that would render valuable diagnostic information impossible to display. The American Dental Association, through the activities of its Working Group 12.1, is promoting interoperability within DICOM as the industry standard for digital imaging in dentistry.

Velocity-image model for online signature verification.
In general, online signature capturing devices provide outputs in the form of shape and velocity signals. In the past, strokes have been extracted while tracking velocity signal minimas. However, the resulting strokes are larger and complicated in shape and thus make the subsequent job of generating a discriminative template difficult. We propose a new stroke-based algorithm that splits velocity signal into various bands. Based on these bands, strokes are extracted which are smaller and more simpler in nature. Training of our proposed system revealed that low- and high-velocity bands of the signal are unstable, whereas the medium-velocity band can be used for discrimination purposes. Euclidean distances of strokes extracted on the basis of medium velocity band are used for verification purpose. The experiments conducted show improvement in discriminative capability of the proposed stroke-based system.
