Our contributions are designed to better protect the patient's data and to increase the functionality and interoperability of smart cards in health care. Our solution, called SAMSON, consists of two types of smart cards. The first, a security card, is issued to all personnel within any medical organization, while the second, the medical card, is issued to patients and used to securely store and retrieve health care information. These smart cards are being tested within a 14 hospital federated consortium in Michigan's Upper Peninsula.

However, issues within the medical field such as interoperability, scalability and security continue to plague electronic exchange of information within the healthcare sector. In this paper we present an approach, called~ecure !!ealthcare Information Exchange for Local)!omains (SHIELD), which defines strategic components within an architecture that solves the problem of interoperability, scalability and security. Our solution integrates biometric and smart card technology that permits each hospital to exchange medical data with other hospitals within the trusted federation, without sacrificing the ability for individual hospitals to maintain their own policy enforcement. This research is currently being implemented within one Regional Center and fourteen hospitals within the Upper Peninsula of Michigan in the United States.

The Health Insurance Portability and Accountability Act (HIPAA) mandates that patient information can only be accessed by authorized personnel. The complexity of this task increases significantly when associated with a rural healthcare network due to a combination of factors, including economic disadvantages, educational shortcomings, inadequate infrastructure, lack of support by legislators, the sheer isolation of living in remote rural areas, and frequent needs to share patient's information across hospitals. This paper analyzes a rural healthcare network in Michigan's Upper Peninsula and introduces the Security for Clinical Authorization and Authentication on Health Care Networks (SCAAHN) system. A centralized repository is configured to store health level 7 (HL7) data from various healthcare organizations affiliated with the common network. Standard Electronic Medical Records (EMRs) containing patient's information can be securely accessed by authenticated and authorized personnel throughout the healthcare network. The preliminary results indicate that SCAAHN within the rural healthcare architecture has enhanced the authentication and authorization of patient records, and provided secure access to patient's information via a web portal interface.

Consequences of misidentification include incomplete and inaccurate electronic patient health records potentially jeopardizing patients' safety, a significant amount of cases of medical fraud because of inadequate identification mechanisms, and difficulties affiliated with the value of remote health self-management application data being aggregated accurately into the user's Electronic Health Record (EHR). We introduce a new technique of user identification in healthcare capable of establishing a global identifier. Our research has developed algorithms capable of establishing a Unique Health Identifier (UHID) based on the user's fingerprint biometric, with the utilization of facial-recognition as a secondary validation step before health records can be accessed. Biometric captures are completed using standard smartphones and Web cameras in a touchless method. We present a series o...

Accurate patient identification is often overlooked in the areas of security and privacy. We have used our own architecture and experiences to bring forward this problem and offer suggestive solutions of incorporating biometric fingerprints and photographs of patients in a strategic manner to help strengthen our healthcare security model.

The application utilizes Microsoft Kinect to detect and track body joints and then calculates nine gait parameters that are important for performing a gait assessment. The measurements of the hip flexion/extension, hip abduction/adduction and knee flexion/extension followed the graphs of standard gait pattern. Also they were consistent and homogeneous among all ten participants. Due to the low tracking accuracy for both the ankle and the foot, measurements of ankle plantar flexion and dorsiflexion didn’t follow the trajectory of the standard graph. Moreover, measurements from participants were sparsely distributed across their average value.

This technology has revolutionized the voice telephony field and significant research has been conducted in this area. Therefore, it becomes critical to implement the latest developments of this technology into academic programs associated with technology, in order to provide adequate training and education to students and professionals. In this paper, we present the drawing and implementation of a senior design project, Asterisk VoIP in a Commercial Environment, which is associated with developing and testing an open-source VoIP solution for a small medical institution. This project consists of building a test environment that emulates the participating institution's network and designing an open-source VoIP system, where its end result will be compared against the institution's current commercial VoIP solution. This design will incur both technical and economical analy...

Estas doenças têm um importante impacto nas atividades diárias dos pacientes em virtude do comprometimento locomotor, como as mãos. O objetivo deste trabalho foi o de avaliar a mão de pacientes com MPS utilizando a versão brasileira do Michigan Hand Outcome Questionnaire (MHQ). Dos 16 indivíduos selecionados, entre 8 e 21 anos, portadores de MPS, 87.5%, apresentaram MPS IV, sendo as atividades de vida diária o domínio mais acometido com (46.87%). A versão brasileira do MHQ demonstrou ser eficiente, consistente e confiável para avaliação e quantificação do acometimento da mão na MPS. Artigo original: Marcos A. Matos, PhD, Ingrid C. F.

Nevertheless, studies showed that the Kinect manifested inaccuracy when tracking the joints of the lower body, especially in non-ideal tracking conditions. In this work, a new algorithm was proposed for rectifying this tracking problem. As a proof of concept, the proposed algorithm was implemented only for the ankle joint because its readings contained the noisiest return values when compared to other joints. The proposed algorithm was used for inferring the joint's position in the 3D space. We were able to infer the ankle joint's position using the subject's gait pattern as expressed by the lower joints' angles and geometric relationships between these joints.

Rural locations more commonly face shortage of physicians, a lack of high-paying jobs with adequate insurance benefits, transportation, health literacy, a stigma with health conditions due to lack of anonymity and difficulties accessing specialty care. Rural communities see higher rates of suicide, heart diseases, respiratory disease, stroke, social isolation, and public health crisis such as the opioid epidemic. More than 46 million Americans, or 15% of the population, live in rural areas within the United States.
